Other mistake: In the fight scene outside Trish's apartment, Jet Li kicks Maurice so he gets a scar on the right side on his lip. Later in the American football sequence you can at one shot see that he has the scar on his left side of the lip and in another shot it's completely gone.
Other mistake: In the scene where Colin and his girlfriend get thrown out of their apartment windows, the camera follows them down during their fallings until they splash into the water. Look closely at the skin of the girl and it is actually much "whiter" than it was before (the stuntwoman that took her place was white, not black). (00:55:20)
