Continuity mistake: When Jet-Li finds the paper with addresses in his brother's car, he wrinkles it when he puts it in his pocket. As he shows it to Aaliyah some time later it is a nice, unwrinkled piece of paper. (01:00:30 - 01:03:15)
Continuity mistake: Despite the story being set in California, during many driving scenes, "BC Transit" buses can be seen, indicating the shooting location of Vancouver.
Continuity mistake: During the final fight when Jet gets thrown through the wooden framework, as he falls you see a black boxy shape on the right side of the screen. That's the camera recording his fall, and when he looks into the lens you get confirmation of the camera. (01:41:50)
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)
Revealing mistake: Throughout the entire film, whenever a character performs a high flying martial arts move, you can see that they are holding on to their wires.
Continuity mistake: At the end of the fight scene on the stairs outside of Trish's apartment she comes to her balcony and looks down at the men on the ground. Next to her are some potted plants that vanish a few moments later when the shot changes back to her as she watches Jet drive off.
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)
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: During the fight, if you look closely, you can see the wire that holds the brazier in the air.
