Trivia: In the scene where Alex approaches the two girls at the record stand you can see the original score for 2001: A Space Odyssey, also directed by Stanley Kubrick.
Suggested correction: The album shown in the picture is NOT, as is commonly believed, the soundtrack of 2001, but rather a compilation of movie theme music that includes the main theme of 2001. However, the ACTUAL soundtrack of 2001 is still visible in the scene, just a little earlier: When Alex finishes flipping through a magazine and tosses it down on a counter, one of the records in that shot is the 2001 soundtrack.
Trivia: At the end of the opening credits, just after "Screenplay by David Mamet" and before "directed by Ridley Scott", look at the right hand side of the screen - you can see Hannibal's face drawn by pigeons. (00:04:25)

Trivia: When Sean is learning how to drift at the docks, the fisherman that comments about his drifting is actually the real Drift King, Keiichi Tsuchiya.

Trivia: When Eric first goes back to his apartment, right after he returns from the grave, it is raining inside the apartment and his movements look an awful lot like the movements he just made in the rainy alleyway. [Not really a mistake, but worth noticing - the filmmakers were forced to re-use some shots after Brandon Lee's death.]
Trivia: 13 Mustangs from 1967-1968 were modified to be "Eleanor" in the movie. One was a True Shelby GT500, but this was used by Bruckheimer as a reference piece and used by him personally.

One was chopped up to film certain sequences (in car shots, etc.), 2 were destroyed, and the other Mustangs were modified to perform certain tasks (Chases, Jumps, etc.).
Trivia: The movie wasn't based on a true story. The Coen brothers just threw that in.
