Continuity mistake: In the scene where Jet-Li sprays Maurice and the other henchmen with water from the hose, one of them stops him by chopping the hose with an axe but if that was the case the water should have continued to spray wildly from the bit where he chopped it. The water just stops instead. (01:28:50)
Continuity mistake: In the scene where Trish lets Han into her bedroom at her father's house, a small white rocking horse figurine can be seen on the top shelf on the wall next to her bed. When Trish's father knocks on the door and comes in, the figurine disappears from the shelf and reappears under the bed when Trish reaches for it. (01:20:45)
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.
Continuity mistake: In the scene where Aaliyah and Jet are being chased by the two motorcycles, one of them catches up to them - it is seen that he shoots out both driver and passenger windows, but when the shot changes to Aaliyah's side (passenger) the window is still intact then when it goes back to Jet's side it is shot out again.
Continuity mistake: Before the barber shop is blown up, the man getting shaved has a full coat of shaving cream on his right cheek. Then during a close-up, the shaving cream on the right cheek is much less. But then when it goes back out to a farther camera angle, the cheek is coated with more shaving cream again.
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)
Continuity mistake: In the scene where Jet Li is at the funeral of his brother you can see a wedding ring on his dead brother's left hand, then when the camera goes to a different angle the ring magically disappears. (00:45:00)
Continuity mistake: During the fight, if you look closely, you can see the wire that holds the brazier in the air.
