Trivia: When Harrison Ford is walking through the old guy's mansion, there is a shot of them walking down a hallway. This is the same shot (and house for that matter) that was used in the movie Fletch when he was talking about how Hopalong Cassidy used to live in that house. The front of the house with the fountain in the middle of the circle driveway is also recognizable.
Trivia: There is one error in the Tag Team race: the street is not that long. (I should know, because my dad works on that street.) In the movie, it took a little while to finish getting down that street which was unbelievable, especially at the speed they were going. In reality, if you were to race down that street from where they started (without turning back) it would take you an estimated eight to nine seconds.
Trivia: In the film poster, the "Not alone" on Halle Berry's forearm is written running from wrist to elbow. However, in the film, when she removes her bandages, it runs elbow to wrist.

Trivia: When Dustin Hoffman and Gene Hackman have their showdown in the lavatory towards the end, Hackman greets him and says that this is a "long overdue pleasure." This is a reference to the fact that this scene is the first scene ever between Hoffman and Hackman, two former classmates at film school, in their substantial screen careers. Despite being in the industry for decades, and being long-time friends, they had never made a movie together.
Trivia: The scene directly before the first victim, "the movie star", is killed she is talking to herself in the mirror. You can see her reflection and the reflection of the window behind her. If you pay close attention you can see that there is a silhouette in the curtains. Eventually the lightning flashes and you can see the face of the little boy in the silhouette looking into the window at her.
Trivia: Colin Farrell recorded a version of The Clash's "I Fought the Law..." for the film.
Trivia: When Willard's boss is working on his spreadsheet program, just before the rats show up, he is not entering the spreadsheet formula properly. He is entering the actual numbers like 235+345+315 instead of using cell addresses like =A1+B1+C1. Not really a mistake because his character could be an idiot on spreadsheets. Just an interesting observation.
Trivia: In the DVD commentary, Tony Martin (director) reveals that all the behind-the-scenes crew had roles as extras in the movie. One dolly grip refused to be in it, but Tony got lucky, as that dolly grip was the one reflected in the security guard's windows during the computer scenes. Instead of digitally taking him out, he left it it thus justifying his rule.
Trivia: I don't speak Spanish, however, after asking my fiance (from Mexico) to carefully watch the scene when Memo talks to his right hand man, it explained the movie better. If you know Spanish and listen to the dialogue carefully, you hear Memo asking his right hand man to kill his son. That explains A LOT.
Trivia: Roger Donaldson's mother Dorothy appears as a bystander in a street scene where Colin Farrell is running for a taxi.
