Continuity mistake: During the chase scene, there is a Citroen XM series II (the citroen sign in the middle, on the front) and then there's a Citroen XM series I (the citroen sign on the driver's side, on the front). It changes back and forth a couple of times. There's also a difference at the bottom of the car; the series I carries the name Citroen XM on the left side, while the series II bears a Citroen sign on the left side and the XM sign on the right.
Trivia: In many of the stunt car scenes you can see the actors apparently driving. The producers used British RHD cars and fitted phoney steering wheels on the passenger sides to make it look as if the stars were really driving.
Sam: Whenever there is any doubt, there is no doubt. That's the first thing they teach you.
Vincent: Who taught you?
Sam: I don't remember. That's the second thing they teach you.
