I saw this over at ohnotheydidnt and thought it was really fun to read! I took the most interesting ones from the original post to share here.

"We all love movies, and its interesting to find out that the final cut we see in theatres or on TV isn't always what was originally imagined or intended by the creators. I raided the Internet Movie Database and picked some more famous flicks (and one Paris Hilton movie for the lolz) and compiled a list of trivia, i.e. lines that were ad-libbed, actors originally offered parts, script changes, deleted scenes, and random interesting facts. Enjoy!"

Psycho

- Considered for the role of Marion were: Eva Marie Saint, Piper Laurie, Martha Hyer, Hope Lange, Shirley Jones, and Lana Turner.

- Alfred Hitchcock originally envisioned the shower sequence as completely silent, but Bernard Herrmann went ahead and scored it anyway and Hitchcock immediately changed his mind.

- An early script had the following dialogue: Marion: "I'm going to spend the weekend in bed." Texas oilman: "Bed? Only playground that beats Las Vegas." (This discarded dialogue was resurrected for the Gus Van Sant remake, but was subsequently cut.)

- Alfred Hitchcock received several letters from ophthalmologists who noted that Janet Leigh's eyes were still contracted during the extreme closeups after her character's death. The pupils of a true corpse dilate after death. They told Hitchcock he could achieve a proper dead-eye effect by using belladonna drops. Hitchcock did so in all his later films.

- In Robert Bloch's novel, Norman Bates is short, fat, older, and very dislikable. It was Hitchcock who decided to have him be young, handsome, and sympathetic. Norman is also more of a main character in the novel. The story opens with him and Mother fighting rather than following Marion from the start.

- Alfred Hitchcock and Joseph Stefano originally conceived the film with a jazz score instead of Bernard Herrmann's miniature string orchestra.

- The character played by Janet Leigh was originally called Mary Crane.

- SPOILER: Alfred Hitchcock tested the fear factor of Mother's corpse by placing it in Janet Leigh's dressing room and listening to how loud she screamed when she discovered it there. LMFAO That's so screwed up.

- SPOILER: The MPAA objected to the use of the term "transvestite" to describe Norman Bates in the final wrap-up. They insisted it be removed until Joseph Stefano proved to them it was a clinical psychology term. They thought he was trying to get one over on them and place a vulgarity in the picture.

- SPOILER: During preproduction, Hitchcock said to the press that he was considering Helen Hayes for the part of Mother. This was obviously a ruse, but several actresses wrote to Hitchcock requesting auditions.

- SPOILER: Alfred Hitchcock even had a canvas chair with "Mrs. Bates" written on the back prominently placed and displayed on the set throughout shooting. This further added to the enigma surrounding who was the actress playing Mrs. Bates.

- SPOILER: Alfred Hitchcock was very uneasy about the morphing of Norman's face into Mother's at the end of the film. He sent out three different versions of the film during its initial release. The first version included the ending seen on all prints today, the second contained no morphing at all, and the third contained the trick at the end, yet also included it at an earlier point in the film. When Sam Loomis comes back to the Bates Motel to look for Arbogast, there is a zooming shot of Norman standing by the swamp, looking very sinister. The third version of the film included the subtle morphing of Norman's face into Mother's at this moment.

- SPOILER: Alfred Hitchcock paid the title sequence designer Saul Bass (also credited as "Pictorial Consultant") US$2,000 to draw storyboards for the scene where Arbogast is killed at the stairs. Brass was excited about the movie and asked Hitchcock for the opportunity. Hitchcock discarded his work because the shots showed Arbogast's feet slowly going up the stairs and this prepared the audience for a shock. Hitch wanted it to be a surprise and that's why he filmed Arbogast in a completely natural way.

Pirates of the Caribbean: The Curse of the Black Pearl

- The film was such a success that Disney closed the Pirates of the Caribbean attractions at Disneyland and Disney World to update them. The new storyline of the attractions will be that Captain Barbosa is chasing Jack Sparrow, both of which will be added in the form of animatronics. Disneyland opened their updated attraction on 26 June 2006, two days after the sequel's world premier. Disney World opened its new attraction on 7 July 2006.

- Jack Sparrow's line "...and then they made me their chief," is a tribute to British comedy series "The Fast Show" (1994), of which Johnny Depp is an ardent fan, so much so that he guest starred in one episode. The line was originally said by a character, played by Mark Williams, who usually appeared in a kitchen and is, in its entirety "...and then they made me their chief. Which was nice." The line has also been said by another character, in The Fast Show, Sir Roly Birkin (played by Paul Whitehouse), who blurts out random sentences during his drunken, mumbled ramblings. The Fast Show was shown in the US under the title "Brilliant". (Depp uses another Fast Show catchphrase (again from a Mark Williams character) in an unused version of the "parley" scene in the cave when he says, "I'll get me coat..." - this can be seen on the DVD.)

- Johnny Depp improvised Jack Sparrow's catch phrase, "Savvy?"

- One of the film's last lines - "Bring me that horizon" - was conceived by Johnny Depp on the morning the scene was filmed.

- Johnny Depp wore contact lenses which served as sunglasses so he wouldn't be squinting in the sun all the time.

- Keira Knightly wore colored contact lenses like Johnny Depp's in the last scene of the movie. But since her eyes are lighter than Johnny Depp's, they had to be dark in the center and light on the outside. She complained they made her so dizzy that she threw them away the night after shooting.

- The title was originally just "Pirates of the Caribbean" but the name was changed in the hope that it would do well at the box office and a sequel could be made.

- The scene where Orlando Bloom impersonates Johnny Depp's performance was devised by Bloom who asked producer Jerry Bruckheimer if he could put it into the movie.

- Alan Silvestri was first suggested to provide the score but has been replaced by Klaus Badelt. However, some movie posters still show the credit "Music by Alan Silvestri". These posters also show a different story credit, omitting the fourth story writer Jay Wolpert: "Screen Story by 'Beattie, Stuart' and Ted Elliott and Terry Rossio".

- When Ted Elliott and Terry Rossio, the screenwriters, originally pitched the movie to the Disney executives in the early '90s, it was rejected.

- The various "eunuch" lines were improvisations by Johnny Depp.

- When filming in the cave, excessive makeup was added to the characters so they wouldn't looked washed out on film. When the crew realized how cool the makeup looked on Johnny Depp, they continued to use it on him for the rest of the movie.

- Michael Keaton, Jim Carrey, and Christopher Walken were all considered for the role of Captain Jack Sparrow.

- Jude Law, Ewan McGregor, Tobey Maguire, Christopher Masterson and Christian Bale were all considered for the role of Will Turner.

- According to the DVD commentaries, Geoffrey Rush has a theory that people watch the screen from left to right, just like when they read a book. Therefore, he tried to be in the left side of the screen as often as possible. He was particularly intent on doing this in the scenes with the monkey and Keira Knightley because he didn't think anyone would look at him otherwise.

Moulin Rouge!

- Catherine Zeta-Jones and Heath Ledger were contenders to play Satine and Christian.

- Filming was halted for two weeks in November 1999 after Nicole Kidman fractured two ribs and injured her knee while rehearsing a dance routine for the film. Many of the scenes where she is seen only from the chest up were shot while she was in a wheelchair.

- The necklace worn by Nicole Kidman was made of real diamonds and platinum and was the most expensive piece of jewelery ever specifically made for a film. The Stefano Canturi necklace was made with 1,308 diamonds, weighing a total of 134 carats and was worth an estimated US$1 million.

- The stage for "Spectacular Spectacular" was especially reinforced to hold the weight of a galloping horse for a scene where the evil Maharaja rides across the stage. The scene was abandoned but the white horse still appears fleetingly in one shot.

- "Come What May" was written by David Baerwald for Romeo + Juliet (1996) but not used. In Moulin Rouge, it is newly written for the stage show by Christian. However, it is the only completely original song in the entire film.

- The "placeholder" name of the Duke (Richard Roxburgh) during the writing of the script was Count Von Groovy.

- A scene establishing the "Gothic Tower" as a bordello was cut. It involved dancers in S&M gear performing Grace Jones's "Slave to the Rhythm".

- According to an interview with Craig Pearce on the DVD extras, an early draft of the script had the Count seducing both Satine and Christian and then hooking them on morphine.

- Cameo: [Tara Morice] the female lead in Baz Luhrmann's Strictly Ballroom (1992) briefly appears as a prostitute in the opening sequence.

- Renée Zellweger was next in line after Nicole Kidman to play Satine. Sharleen Spiteri was also a finalist. Renee's a great actress and all, but, uhhh, those squinty eyes would have ruined it for me, sorry.

- Courtney Love was seriously considered for Nicole Kidman's role as Satine but was the director thought she didn't fit well with the movie. Nevertheless, she allowed Baz Luhrmann to use Nirvana's "Smells Like Teen Spirit" in the opening sequence, even when she rarely lets anyone use her late husband's (Kurt Cobain) work in film or TV.

- Originally, the green fairy was going to be a long-haired muscle man with a giant sitar and Ozzy Osbourne was hired to provide the vocals. Eventually it was changed to the current "Tinker Bell" incarnation, played by Kylie Minogue, but Osbourne still gives voice to the fairy's guttural scream when it turns evil.

- Cat Stevens would not license his song "Father and Son", which was the first musical number in the original script, because of his current religious beliefs. He objected to the sexual content in the film. The scene featuring "Father and Son" was to have been between Christian and his father in his father's office, with all his father's employees joining in for the chorus. This was to be the segue into his leaving home for Paris. The scene is included in the complete script on the Special Edition DVD.

- Kylie Minogue recorded other songs for use, including "Physical", originally recorded by Olivia Newton-John.

- The song "My Way", made popular by Frank Sinatra, was considered to be performed by The Duke for the film, but this never developed. However, The Duke still repeatedly yells, "My way!" during the finale.

- Real Moulin Rouge dancers of the time wore split knickers under their dresses, a technical point that the film-makers chose not to follow in order to obtain a PG-13 rating.

- John Leguizamo did the entire climactic scene from a squatting position to give him greater mobility in his role. Consequently he had to endure several weeks of physical therapy afterwards.

- In the "Like a Virgin" number, Jim Broadbent's voice is dubbed by an opera singer, mimicking Broadbent's own vocal performance. This segment took a week to film.

- Stereophonics' lead singer Kelly Jones says he was approached about playing a part in the movie but turned it down.

- Jake Gyllenhaal auditioned several times for the part of Christian, but was ultimately deemed too young to play opposite Nicole Kidman.

- Singer Ronan Keating auditioned for the role of Christian.

- The word "love" and its variations (loved, loves, loving, lover and lovers) appears in this film 143 times.

- John Leguizamo was originally considered for the role of The Argentinean.

- Some of John Leguizamo's speech in the scene after Satine rejects Christian is taken from Lautrec's own correspondence.

- In original drafts of the script, Satine had a three-year-old child and the story was told in flashbacks, told by Christian to the child.

- Natalie Jackson Mendoza was originally cast as Satine, but was replaced by Nicole Kidman. Mendoza still plays a role in the film as China Doll.

Titanic
- The studios wanted Matthew McConaughey, but Cameron insisted on Leonardo DiCaprio

- When James Cameron decided to include real footage of the Titanic's remains on the seabed, he did not want to simply shoot from inside a submersible as had been done for the IMAX documentary Titanica (1995). To allow filming from outside the sub, Cameron's brother Mike Cameron and Panavision developed a deep-sea camera system capable of withstanding the 400 atmospheres of pressure at that depth.

- James Cameron went on the dives to the real Titanic himself, and found it an overwhelming emotional experience to actually see it. He ended up spending more time with the ship than its living passengers did.

- When Jack (Leonardo DiCaprio) is preparing to draw Rose (Kate Winslet), he tells her to "Lie on that bed, uh I mean couch." The line was scripted "Lie on that couch", but DiCaprio made an honest mistake and James Cameron liked it so much he kept it in.

- Cameron drew all the pictures in Jack's sketchbook. In fact, the hands seen sketching Rose wearing the necklace are not Jack's, but director James Cameron's. Since he is left-handed and Jack right-handed, the shots were mirror-imaged in post-production (see also the goofs entry).

- The scene in which Rose meets Jack to thank him for saving her life was improvised by the two actors at James Cameron's request, and the spitting scene was almost all ad-lib. Cameron also credits Kate Winslet with writing the heart-wrenching "This is where we first met" line during the final sinking, as well as suggesting Rose spit in Cal's face rather than (as scripted) jab him with a hairpin.

- In the scene where the water comes crashing into the Grand Staircase room, the film makers only had one shot at it because the entire set and furnishings were going to be destroyed in the shot.

- In the scene of Rose looking through the corridors for Jack, the water used was actually from the Pacific Ocean at the Baja California, Mexico set. The water was so cold that when Rose gasps when she first dives into the water, it was actually Kate Winslet's genuine reaction to the frigid ocean.

- Gloria Stuart, being only 86, was aged by makeup to play Rose at age 101. She did not find this a pleasant experience.

- In preference to hiring new extras all the time and repeatedly having to fit them for clothes and coach them in proper 1912 mannerisms, a group of 150 "core extras" was hired who would stay with the picture through the entire production. They and other performers learned proper 1912 behavior in a 3-hour course from Lynne Hockney, who was also the film's choreographer. Hockney also produced a video "Titanic Etiquette: A Time Traveler's Guide", which was then left playing continuously in the wardrobe department.

- Many of the "core extras" used for the movie took on characteristics of actual survivors -one scene where two little girls are loaded onto a lifeboat and he says "its only for a little while" is based on survivor testimony of one of the girls who survived.

- On the final night of shooting in Nova Scotia, one or more pranksters mixed PCP (angel dust) into the clam chowder served to the cast and crew. 80 people were taken ill, many hospitalized with hallucinations. Bill Paxton felt listless for two weeks after the incident.

- In the scene where Jack and Rose are walking the deck and talking, Rose calls herself a "poor little rich girl". Gloria Stuart, who plays old Rose, was actually IN the film Poor Little Rich Girl (1936).

- At $250 million, the movie cost more than the Titanic itself. The cost to construct the ship in 1910-1912 was £1.5 million, equivalent to $7.5 million at the time and about $120 to $150 million in 1997 dollars.

- Rose, in her old age, owns a Pomeranian. A Pomeranian was one of only three dogs known to have survived the disaster. As the real ship sank, a passenger freed dogs from their kennels, and a survivor later recalled a French bulldog swimming in the ocean. Cameron filmed scenes portraying the doomed animals but cut them.

- When James Cameron was writing the movie, he intended for the main characters Rose DeWitt Bukater and Jack Dawson to be entirely fictitious. It was only after the script was finished that he discovered that there had been a real "J. Dawson" who died aboard the Titanic. This "J. Dawson" was trimmer Joseph Dawson, who had been born September 1888 in Dublin, Ireland. His body was salvaged and buried at Fairview Lawn cemetery in Nova Scotia with many other Titanic victims. Today, his grave stone (#227) is the most widely visited in the cemetery.

- Cameron regular Michael Biehn was nearly cast as Cal Hockley and attended numerous meetings with director James Cameron to discuss the role, though ultimately the part went to Billy Zane.

- Rob Lowe was considered for the role of Cal Hockley.

- Fay Wray was originally offered the role of the older Rose but turned it down, saying, "I think to have done 'Titanic' would have been a tortuous experience altogether". Hollywood legend 'Ann Rutherford' also turned it down.

- After finding out that she had to be naked in front of DiCaprio, Kate Winslet decided to break the ice, and when they first met, she flashed him.

- Has the longest cinematic release, it stayed on US movie charts from December 19, 1997, until September 25, 1998, a duration of 281 days.

- Leonardo DiCaprio and Kate Winslet committed to the film even before the script was written, on the basis only of a 165-page outline Cameron had written.

- Christian Bale auditioned for the role of Jack Dawson, but was turned down because James Cameron didn't want two British actors playing the lead roles of two Americans.

- Macaulay Culkin was considered for the role of Jack Dawson

- Reba McEntire was offered and had accepted the role of the unsinkable Molly Brown, but due to later schedule conflicts had to turn it down.

- Gwyneth Paltrow was also up for the role of Rose Dewitt Bukater but lost to Kate Winslet THANK GOD!

Pulp Fiction

- Quentin Tarantino hesitated over the choice between the character he was going to play: Jimmie or Lance. He ended up choosing Jimmie's role because he wanted to be behind the camera in Mia's overdose scene.

- Quentin Tarantino originally wrote the role of Jules specifically for Samuel L. Jackson, however it was almost given to 'Paul Calderon' after a great audition. When Jackson heard this, he flew to LA and re-auditioned, getting back the part he was supposed to play. Calderon ended up with a cameo as Paul, the bartender.

- The parts of "Honey Bunny" and "Pumpkin" were written specifically for Amanda Plummer and Tim Roth.

- Jules's character was originally written to have a gigantic afro, but a crewmember obtained a variety of afro wigs and one jheri curl wig. Quentin Tarantino had never thought about a jheri curl wig, but Samuel L. Jackson tried it on, Tarantino liked it, and it was kept.

- The shot of Vincent plunging the syringe into Mia's chest was filmed by having John Travolta pull the needle out, then running the film backwards.

- The Big Kahuna burger was also eaten in the movie From Dusk Till Dawn (1996) and first appeared in Reservoir Dogs (1992).

- Director Trademark: [Quentin Tarantino] [Red Apple cigarettes] Butch smokes "Red Apple" cigarettes. The same brand is smoked by Tim Roth's character in Four Rooms (1995).

- Quentin Tarantino wrote "The Wolf" character specifically for Harvey Keitel

- In a cut scene Vincent tells Mia he's been fantasizing about being beaten up by Emma Peel of the Avengers. Later, in 1998, Uma Thurman did star as Emma Peel in the movie The Avengers (1998).

- The role of Marsellus Wallace was originally going to be played by Quentin Tarantino favorite, 'Sid Haig' . At the last minute, Haig turned it down, saying that it was "too TV".

- Uma Thurman originally turned down the role of Mia Wallace. Quentin Tarantino was so desperate to have her as Mia, he ended up reading her the script over the phone, finally convincing her to take on the role.

- John Travolta's character, "Vincent Vega", is the brother of "Vic Vega", aka "Mr. Blonde" from Reservoir Dogs (1992).

- The role of Vincent Vega was written for Michael Madsen, who played the character's brother, Vic Vega, in Reservoir Dogs (1992), but he couldn't do the film due to scheduling conflicts for another film.

- Speculation abounds as to the nature of the mysterious glowing contents of the case:
~~~ Could it be Elvis's gold suit, seen worn by Val Kilmer (as Elvis) in True Romance (1993)?
~~~ The most persistent theory (most usually attributed to a friend of a friend who saw it posted on a message board by someone whose brother had read a report of a radio interview with Tarantino himself) is that it is Marcellus Wallace's soul. The story goes that when the Devil takes a person's soul, it is removed through the back of the head (this isn't part of any known religion, but this is what the message board posters say). When we see the back of Marcellus's head he has a Band-Aid covering the precise spot indicated by tradition for soul removal. Perhaps Marcellus sold his soul to the devil which would also explain why the combination to open the briefcase is 666.
~~~ Quentin Tarantino has said that the band-aid on the back of Marsellus Wallace's neck had nothing to do with an allusion to the Devil stealing Marsellus's soul... but that the actor Ving Rhames had a scar on the back of his neck he wanted to cover up.
~~~ Or could it be simply a 20-watt light bulb?
~~~ According to Roger Avary, who co-wrote the script with Quentin Tarantino, the original plan was to have the briefcase contain diamonds. This seemed neither exciting nor original, so Avary and Tarantino decided to have the briefcase's contents never appear on screen; this way each filmgoer could mentally "fill in the blank" with whatever struck his or her imagination as best fitting the description "so beautiful". The orange light bulb (projecting shimmering light onto the actors' faces) was a last-minute decision and added a completely unintended fantastic element.
~~~ In a radio interview with Howard Stern in late 2003, Quentin Tarantino was asked by a caller the contents of the briefcase, and he answered, "It's whatever the viewer wants it to be."

- The passage from the Bible that Jules has memorized was mostly made up by Quentin Tarantino and Samuel L. Jackson. The only part that's similar to what the bible says is the part where he says, "And I will strike down upon thee with great vengeance and furious anger. And you will know my name is the Lord when I lay my vengeance upon thee." However, the part about the righteous man and the shepherd are not real.

- The word "f*ck" is used 281 times.

- In real life, Vincent Vega's 1964 Chevelle Malibu convertible belongs to Quentin Tarantino and was stolen during the production of the film.

- The cab driver, Esmeralda Villalobos (Angela Jones) appeared in a 30-minute short called Curdled (1991) in which she played a character who cleaned up after murders. This makes her fascinated by the idea of murder. Quentin Tarantino saw this film and decided to include this character in Pulp Fiction (1994) but as a cabdriver.

- Pam Grier auditioned for the role of Lance's wife Jody. Though she had a great audition, Quentin Tarantino decided not to cast her because he could not imagine Pam Grier getting pushed around the way the character does.

- Quentin Tarantino had originally intended "My Sharona" (by The Knack) to be played during the Gimp torture sequence - but the rights had already been licensed to another film, Reality Bites (1994).

- Sylvester Stallone was briefly considered for the role of Butch.

- In the script, the character of Paul the bartender (played by 'Paul Calderon' ) is referred to as "English Bob" (Jules even refers to English Bob, saying "Yeah, [Winston Wolf] is about as European as f*cking English Bob"), but his line "My name's Paul, and this is between y'all" apparently stuck, as he is credited as 'Paul' in the credits.

- Jules' "Bad Mother f*cker" wallet actually belongs to Quentin Tarantino. The inscription on the wallet is a reference to the theme song of Shaft (1971).

- Quentin Tarantino wrote the script in Amsterdam, in a hotel room and in coffee shop ("Dutch" for hash-bar) Betty Boop. He stayed for several months, and left the video rental store "Cult Video" with an unpaid bill of about $150. This stay explains the references to Dutch culture and customs at the beginning of the movie. Also, the book version of the movie's screenplay includes some cut dialogue between Vincent and Mia - he realizes that she was "the girl in the cowboy hat" in a photo at a hash bar they both visited, the Cobra, which is right across from the Anne Frank house in Amsterdam.

- Daniel Day-Lewis wanted the role of Vincent Vega but Quentin Tarantino turned him down in favor of John Travolta.

- The role of Butch was originally supposed to be an up and coming boxer. Matt Dillon was in talks to play the role, but never committed. Tarantino then changed the role and offered it to Bruce Willis, who had been disappointed at not being signed to play Vincent.

- Isabella Rossellini, Meg Ryan, Daryl Hannah, Joan Cusack, and Michelle Pfeiffer where all interviewed for the role of Mia Wallace. Out of all of them Tarantino said he preferred Michelle Pfeiffer the most.

- Rosanna Arquette also auditioned for Mia, but was offered Jody instead.

- Tarantino originally wanted Kurt Cobain and Courtney Love to play Lance and Jody.

- SPOILER: According to an interview with Phil LaMarr, it was he who came up with the idea of his character Marvin being shot in the face. Marvin was originally supposed to be accidentally shot in the throat and survive. Knowing that Marvin would die a slow, painful death, Vincent and Jules decide that Marvin should be shot in the head and put out of his misery. Knowing that this would make the characters unlikeable, LaMarr took his idea to Quentin Tarantino and he agreed to it.

When Harry Met Sally

- The segments of married couples telling the stories of how they met are real stories that Rob Reiner collected for the film. Actors relate the stories.

- In the museum scene, Harry adlibs, "But, I would be proud to partake of your pecan pie." Sally laughs and looks to her right where Rob Reiner silently prompts her to go with it.

- Before deciding on the title, "Just Friends", "Playing Melancholy Baby", "Boy Meets Girl", "Blue Moon", "Words of Love", "It Had To Be You", "Harry, This Is Sally", and "How They Met", were titles were considered by Nora Ephron, Andrew Scheinman, and Rob Reiner.

- According to screenwriter Nora Ephron the infamous "I'll have what she's having" line was actually suggested by Billy Crystal.

- Sally's picky and crazy eating habits were put into the movie after Rob Reiner saw Nora Ephron ordering her food in the same way Sally did in the movie. When Rob brought this up, Nora said, "I just like it the way I like it," a line which was put into the movie.

- Harry is somewhat based on Rob Reiner. Rob was depressed, and loved being depressed, like Harry Burns in the film. Sally is somewhat based on Nora Ephron. Nora is optimistic, cheerful, loves control, and is the type of person who is "just fine" with everything, just like Sally Albright.

- For the infamous orgasm scene, the original script called for just Harry and Sally to talk about women faking an orgasm, until Meg Ryan suggested that Sally actually fake an orgasm at the table. Rob Reiner loved the idea and put it into the script.

- The orgasm scene was filmed at Katz's Deli, an actual restaurant on New York's E. Houston Street. The table at which the scene was filmed now has a plaque on it that reads, "Congratulations! You're sitting where Harry met Sally."

- Nora Ephron was happy with how the film turned out, but was never happy with the title of the film, and says it's the one thing she would go back and fix if she could.

- While writing the script, Rob Reiner once said, "You know how women have a base of makeup, I have a base of depression. Sometimes I sink below it. Sometimes I rise above it." Since the Harry Burns is based on the depressing Rob, Nora Ephron threw the line into the script, which Rob cut somewhere along the line.

- Molly Ringwald was offered the role of Sally, but was forced to decline due to a busy schedule. She would later go on to play Sally in the stage version of the film in 2004, on London's West End.

- SPOILER: In the first draft of the film, Harry and Sally did not end up together. It was only later, that Nora Ephron and Rob Reiner decided that Harry and Sally belonged together.

Breakfast At Tiffany's

- John Frankenheimer was hired to shoot the film with Marilyn Monroe. When the producers suddenly moved to Switzerland and Audrey Hepburn replaced Monroe, she said she had never heard of Frankenheimer and insisted that he be paid off and another director be hired.

- Author Truman Capote envisioned Marilyn Monroe in the part of Holly.

- Although not visible on camera, hundreds of onlookers watched Hepburn's window-shopping scene at the start of the film. This made her nervous and she kept making mistakes. It wasn't until a crew member nearly got electrocuted behind the camera that she pulled herself together and finished the scene.

- Audrey felt that she was miscast as Holly Golightly in this film, although it was one of her most popular roles.

- The song "Moon River" was written especially for Audrey Hepburn, since she had no training as a singer. The vocals were written to be sung in only one octave.

- At a post-production meeting following a screening of the film, a studio executive, in reference to "Moon River," said, "Well, I think the first thing we can do is get rid of that stupid song." Audrey Hepburn stood up at the table and said, "Over my dead body!" The song stayed in the picture.

- Steve McQueen was offered the co-starring role. However, he was still under contract for the show "Wanted: Dead or Alive" (1958), which prevented him from appearing. The role eventually went to George Peppard.

- Kim Novak told Larry King that she was offered the part of Holly Golightly before Hepburn.

The Departed

- Martin Scorsese wanted to shoot the film in Boston, where the story is set. But due to concerns on setting up production and politics, the producers chose New York City to double for Boston because of the state's 15% tax credit. The bulk of the movie was shot in New York City while a six week shooting schedule was split in two for Boston, shooting the first half in June and the second half in August.

- Martin Scorsese sent the script to Mel Gibson, offering him an unspecified role. Gibson thought the script was fantastic, but was unable to accept the part because he was starting production on Apocalypto (2006) at the time.

- Denis Leary was offered the role of Dignam in this film, but turned it down due to scheduling conflicts with his television show, "Rescue Me" (2004).

- Gerard McSorley was originally slated to play Queenan but had to drop out of the project.

- As research for his character's occupation, Matt Damon worked with a Massachusetts State Police unit out of Boston. He accompanied them on routine patrols, participated in a drug raid and was taught proper police procedures like how to pat down a suspect.

- Originally, Jack Nicholson turned down his role in the movie, but after a meeting with Martin Scorsese and Leonardo DiCaprio, he was finally convinced to play the role of Frank Costello. The main reason he joined the production was because he had previously done a few comedies, and wanted to play a villain again, and he considered the character of Costello to be the ultimate incarnation of evil.

- Leonardo DiCaprio was cast in the title role in The Good Shepherd (2006), but he dropped out to play Billy Costigan in this movie. Matt Damon then took the role.

- Martin Scorsese had originally wanted to cast a known actress, either Kate Winslet or Hilary Swank, for the part of Madolyn. But he later decided to go with someone new instead (Vera Farmiga).

- Jack Nicholson refused to wear a Boston Red Sox hat during filming and instead wore his New York Yankees hat.

- Originally Brad Pitt was cast as Colin Sullivan, but later dropped out. He continued to produce the film under his (and his then wife Jennifer Aniston's) production company, Plan B.

- The scene where Frank Costello throws cocaine on hookers was one of many bizarre ideas contributed by Jack Nicholson, who also suggested wearing strap-on for the scene with Matt Damon in the porn theater.

Chicago

- John Travolta, Kevin Spacey, John Cusack and Hugh Jackman were all considered for the role of Billy Flynn. Travolta has said to deeply regret declining the part.

- Angelina Jolie auditioned for the role of Velma Kelly.

- Renée Zellweger had no singing or dancing training prior to this film.

- Madonna (specifically for Velma Kelly), Goldie Hawn, Kathy Bates, Rosie O'Donnell, Nicole Kidman, Gwyneth Paltrow, Kristin Chenoweth (for Roxie Hart or Mary Sunshine), Cameron Diaz, Whoopi Goldberg (for Mama Morton) and Britney Spears (by Harvey Weinstein for Kitty Baxter) were all considered for roles in the movie.

- The song "Class" was filmed but not used because it could not fit into the "show-within-Roxie's-mind" concept. It is included as an extra on the DVD release.

- The director wanted Catherine Zeta-Jones to wear her natural long hair in the movie, but she insisted on the short bob. She explained to People magazine that she didn't want her hair to fall over her face and give people a reason to doubt that she did all the dancing herself.

- Producer Marty Richards approached Catherine Zeta-Jones about appearing in his film-adaption of CHICAGO after being wowed by her renditions of carols at a family Christmas party in Bermuda (her and Michael Douglas' home). Richards approached her for the role of Roxie Hart but Zeta-Jones, though not familiar at all with the original show did know that the character of Velma Kelly sang the song "All That Jazz" therefore only wanted to play that role because she wanted to sing that song.

- The speech by Hunyak, translated, is: "What am I doing here? They say my famous tenant held down my husband and I chopped his head off. But it's not true. I am innocent. I don't know why Uncle Sam says I did it. I tried to explain at the police station but they didn't understand." Here it is in Hungarian, just in case: "Mit keresek én itt? Azt mondják, a híres lakóm lefogta a férjem, én meg lecsaptam a fejét. De nem igaz. Én ártatlan vagyok. Nem tudom, miért mondja Uncle Sam, hogy én tettem. Próbáltam a rendõrségen megmagyarázni, de nem értették meg."

- This is the fourth film that John Travolta has turned down and which Richard Gere has accepted, following American Gigolo (1980), Days of Heaven (1978), and An Officer and a Gentleman (1982).

- In the scene in prison where Billy Flynn is passing by the bars, Hunyak starts speaking in Hungarian but the final sentence is in Russian. She says, "Help, help me, please."

- The musical numbers "My Own Best Friend" and "Me and My Baby" were originally written into the script, but were removed at the last minute. "My Own Best Friend" was to have taken place when Roxie and Velma are put in solitary confinement after getting into a cat fight.

- The music heard after Roxie faints, and proclaims that she is pregnant, is the music for the number "Me And My Baby", from the stage musical, originally included in the script.

- When the film rights were originally bought by producer Martin Richards in the 1970s, Bob Fosse was to be involved with the film project, and Goldie Hawn, Liza Minnelli and Frank Sinatra were announced as the stars; but Fosse's death in 1987 ended that attempt at a film version.

- The 1996 smash Broadway revival renewed interest, and new names became leading candidates for starring roles, including Goldie Hawn and Madonna. Nicholas Hytner was brought in as director, and he had Wendy Wasserstein re-write Larry Gelbart's script. The project again went on hold when Madonna withdrew and Nicole Kidman chose to do Moulin Rouge! (2001) instead.

- Charlize Theron had initially secured the role of Roxie Hart while Nicholas Hytner was attached as director. When Hytner withdrew and Rob Marshall took over, Theron had to audition again and lost the lead to Renée Zellweger.

- Mandy Moore auditioned for the role of Kitty Baxter but was passed over because the producers felt she was too young.

- Rob Marshall was originally considered by Miramax to direct the screen version of "Rent"(2005). When he arrived for his interview, he told them he wanted to talk about "Chicago" instead and proposed the "musical in Roxie's mind" concept. Miramax loved the idea and put "Rent"(2005) on the back burner.

- Chita Riviera, who played Velma Kelly in the original Broadway hit has a cameo in this movie - just before Mama Morton comes in, she is smoking and talking to Roxie

House of Wax

- Paris Hilton did not have to audition - she was the director's only choice for her role. The rest of the cast was built around her. LMFAO Why? Was the director that desperate for an STD?

- Throughout the movie, several characters can be heard saying Paris Hilton's (Paige) "That's hot" catch phrase.

- Although Chad Michael Murray's character and his sister are listed to have the last name "Jones", no actual last name was given for them. Chad, in a radio interview, was shocked to hear his character finally had a last name, and said that it was an ongoing debate on set.

- Jared Padalecki is one foot taller than co-star Elisha Cuthbert. To make herself appear taller in scenes where she and Padalecki would be filmed together, Cuthbert taped two-inch blocks of wood to the bottoms of her boots. This was only done during scenes where they would be shot from the knee and up.

- While filming the abandoned sugar mill chase, Paris Hilton was embarrassed by her scream, so the first three times she screamed she had the whole cast and crew scream along with her.

- SPOILER: Warner Brothers granted Paris Hilton permission to sell t-shirts that read "On May 6th, Watch Paris Die" in order to promote the film before its release.

- SPOILER: The death of Paris Hilton's character was originally longer and featured more gore but it was cut for the theatrical release.

Mr. & Mrs. Smith

- Nicole Kidman was originally cast as Mrs. Smith.

- Johnny Depp was originally cast as John Smith, but turned it down after being overworked with other movies he was shooting.

- Catherine Zeta-Jones was also considered for Mrs. Smith, while Johnny Depp and Will Smith were considered for Mr. Smith when it was not sure if Brad Pitt would sign on.

- Cate Blanchett was also considered for the role of Mrs. Smith

- Brad Pitt reportedly left the project after Nicole Kidman dropped out and her replacement had not yet been found. Once Angelina Jolie signed on, he returned to the project.

- In order to get a wider PG-13 audience, a very steamy sex scene between Brad Pitt and Angelina Jolie was cut.

- The original ending featured villains played by Jacqueline Bisset and Terence Stamp. After this was dropped, a second ending was filmed with Angela Bassett and Keith David as the villains. This too was dropped when it was decided that the film did not need a final confrontation with the villains at all.

- Many of the scenes from the trailer were not in the movie, including Brad Pitt riding a bike while shooting and Keith David ordering someone to "bring in everyone," after finding out "it's the Smiths".

- Angela Bassett was cast as Mr. Smith's boss but her scenes were subsequently cut from the film. Her voice is still heard in the film, giving him instructions of his next assignment.

- Gwen Stefani was considered for the role of Jane Smith after Nicole Kidman dropped out.

- Aishwarya Rai was the first choice for "Jane" but she turned it down due to filming dates.

- Body count: 43

- SPOILER: After the Smiths discover each other's identities, Jane speeds away in the car and John is running after her. He ends up tripping and crashing through a fence, and his gun goes off. The trip was a mistake, and Brad Pitt's reaction, as well as his following ad-lib, "Oh dear God," are genuine.

The Breakfast Club

- Emilio Estevez was originally going to play Bender, but Hughes couldn't find someone to play Andrew Clark so Emilio agreed to play Clark.

- Molly Ringwald really wanted to play Allison but Ally Sheedy had already been promised the part.

- Anthony Michael Hall's mother and younger sister play his character Brian's mother and sister in the movie.

- The library in which this movie takes place was actually constructed in the gymnasium of Maine North High School specifically for the film. The school closed down in 1982, two years before filming began. The building had been used for park district purposes and the Chicago Blitz before the Illinois state police bought it, turning it into a police station, which it still is to this day.

- The joke that Bender tells but never finishes (while crawling through the ceiling) actually has no punchline. According to Judd Nelson, he ad-libbed the line. Originally, he was supposed to tell a joke that would end when he came back into the library and said, "Forgot my pencil", but no one could come up with a joke for that punchline.

- The film's title comes from the nickname invented by students and staff for detention at New Trier High School, the school attended by the son of one of John Hughes' friends. Thus, those who were sent to detention were designated members of "The Breakfast Club". "The Breakfast Club" at that school probably took its name in turn from the title of American radio's longest running network entertainment show, broadcast from Chicago, 1933 to 1968.

- Nicolas Cage was originally considered for the role of John Bender but the production couldn't afford his salary at the time. John Cusack was originally cast as John Bender, but John Hughes decided to replace him with Judd Nelson before shooting began.

- Director John Hughes said that the cast rehearsed the entire movie as if it was a play a few times before filming began. After the film was a hit, Hughes was asked to write the script as a play so high schoolers could perform it.

- One subplot that was filmed but deleted showed Principal Vernon watching some women faculty members using the school swimming pool.

- Rick Moranis was originally cast as the janitor; he left due to creative differences and was replaced by John Kapelos.

- The scene in which all characters sit in a circle on the floor in the library and tell stories about why they were in detention was not scripted. John Hughes told them all to ad-lib.

- Other proposed titles were "The Lunch Bunch" and "Library Revolution".

- Deleted scene: There was a scene filmed that was originally part of the chase sequence, when the five are still on their way to Bender's locker. Vernon is getting something from the vending machine in the teachers' lounge. While Vernon is swearing at and hitting the vending machine the five kids have to sneak past him in the hallway, just outside his range of vision. Four of them dash past, but Allison (Sheedy) walks past slowly, turns and looks at him, and stands there, as if daring him to turn and see her. Claire (Ringwald) whispers to the others "she's crazy, but she's so cool" before Allison joins them and they continue on their way to Bender's locker. This scene was cut from the theatrical release and the VHS, but was re-cut back into the TV version as a time-filler due to the entire pot-smoking sequence being cut in the TV edit.

- John Hughes almost fired Judd Nelson because of his negative attitude towards Molly Ringwald off camera. Paul Gleason convinced Hughes that Nelson was a great actor and was merely trying to stay in character.

- The original running time of The Breakfast Club (1985) was about two and a half hours. Thinking the film would not be a hit, Universal Pictures trimmed the running time down to the modern 97 minute version. The studio then destroyed the negatives of the deleted scenes. John Hughes said in a "Premiere" magazine article that he has the only complete copy.

- It was originally suggested that there would be several sequels to The Breakfast Club (1985), occurring every ten years, in which "The Breakfast Club" would get back together.

- Any hope of a sequel to "The Breakfast Club" was basically dashed due to the volatile relationship between John Hughes and Judd Nelson. John Hughes has stated that he would never work with Nelson again. Also, it is unclear whether or not Hughes still holds ill-will against his oft-cast starlet, Molly Ringwald. They had a falling out in the late eighties after Ringwald decided to move on from the teen film genre to pursue more adult roles, thus severing her relationship with Hughes.
