Trivia: When the main agent verifies his hand against the screen, one of the pieces of information listed is 'Sector 7G'. This is where Homer Simpson works at the Springfield Nuclear Power Plant.
Trivia: The date for the newspaper Professor Utonium and Hobo Jojo read is Wednesday, July 3, 2002. That's the day the movie was released into theaters.
Trivia: In the scene right after Eddie Murphy gets in a fight with Owen Wilson and Eddie gets arrested, Owen is walking in an industrial area. While he is walking a "stray" dog runs behind him. I personally know that this dog belongs to the director.
Trivia: The shot of Meg turning on the security screens took 57 takes before director David Fincher was happy.
Trivia: Christopher Walken made the trick shot in Phil's poolroom upstairs on the first try. According to the filmmakers, this was supposed to be one of several practice shots, but the cameras were rolling "just in case" he made it.
Trivia: Monty mentions that he'd like to be the girl from 'X-Men' who can walk through walls. Both Anna Paquin and Brian Cox have appeared in at least one 'X-Men' movie, though neither as Kitty Pryde (the girl who can walk through walls).
Trivia: In the trailers (on the radio in the UK, anyway), there's a bit with Hugh Grant saying something like "This is no job for a grown up - drinking without being responsible...actually, it doesn't sound that bad". This was never in the finished film.
Trivia: Ben Affleck is the third actor to play Jack Ryan. His predecessors are Harrison Ford (Clear & Present Danger, Patriot Games) and Alec Baldwin (The Hunt for Red October).
Trivia: Not a mistake, just something nice to notice: "Dormer" sounds like "dormeur" that is to say the French for "sleeper".
Trivia: When Jimmy & Jordan are talking about their plans for their last night together, Jimmy says that he and Nick are having cocktails with their psych. prof. and that Jordan could come too. She says no and "call me later and if not I guess I'll just meet you at the party." This is what we hear, but what her mouth really said was, "Just call me later and I'll see if I can get reservations at [unclear restaurant name]. What she really said can be found in the deleted scenes. (00:05:40)
Trivia: Christian Bale declined an offer to reprise his role of Patrick Bateman from "American Psycho."
Trivia: Quite a few pop culture icons appear in this film such as Ron Jeremy who plays the bartender, Rob Halford of Judas Priest who plays the porn store clerk, Debbie Harry the lead vocalist of Blondie who plays the neighbor and of course Billy Corgan of the Smashing Pumpkins who plays the doctor.
Trivia: When this film was made, many of the original, Russian crew members involved in this historic incident were very upset about the submarine crew being portrayed as drunkards. Oddly enough, one of the promotional items given out at premieres and to executives was a silver K-19 vodka flask.
Trivia: During the film's original outdoor reception Jake carries Melanie, who feigns death after having supposedly been struck by a lightening bolt, towards the wedding guests. Jake announces, "Melanie Carmichael is dead" but then a few seconds later he says, "Long live Felony Melanie." Jake and Melanie do this as a practical joke. The reaction of Melanie's mother at the supposed death of her daughter apparently upset the test audiences so much, that the production crew reshot the whole reception scene, minus the practical joke.
Trivia: Winona Ryder's onerous contractual stipulation about her being provided a bowl of Mike 'n' Ikes with the cherry ones removed was based on the rock band Van Halen's actual contract, which contained a similar clause about green M&Ms. Its purpose was to ensure that the rest of the contract would be followed to the letter.
Trivia: In the biblical book of Jonah, there is actually no whale that swallowed Jonah. The "whale" is a mistranslation of the Hebrew word for a big fish by the translators of the King James Version. Because of the prominence, respectability, and the wide distribution (it is in the public domain in the U.S., but not in the U.K.) of the King James translation over modern translations like the New International Version, the "whale" is what most Bible readers think of the sea creature that swallowed Jonah.
Trivia: The house at the marina is the same house used in the movie "The Island". They escape from the underground bunker and trace their (clone) host(s), Lincoln Six Echos, who lives in the identical house at the marina. Look at the staircase. (01:30:30)
Trivia: All the special effects in this movie were done by Tom Savini, who also plays a Utah detective.
Trivia: Did anyone else pick up the Indiana Jones and the Temple of Doom rip-off/reference? When Mathyus is in the harem of Lord Memnon and the archers come in, he cuts the gong off the wall and runs behind it as a shield, while the guards shoot at it in vain. He then busts out the window and jumps out of it.
