Continuity mistake: When Jet Li is playing football in the park and Maurice falls on top of him, Maurice's scar is on the left side of his lip, then when the camera cuts back to him it's on the right side. (00:50:40)
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: 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: 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: When Aaliyah first gets in the cab that Jet Li has stolen she has brownish colour lipgloss on, but when Jet is done driving her to where she needed to go, her lipgloss is clear without a trace of the brownish color.
Continuity mistake: When Jet Li picks up the cigar in the office, the length changes in the next scene; it is longer. (01:04:30)
Continuity mistake: When the two people on motorcycles are chasing Jet Li and Trish, at one point the car turns around and heads away. The bulletholes in the window disappear when you see it from behind.
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: During the scene where Jet Li is holding a man behind his back by his neck on the stairs outside of Trish's apartment the man's orange baseball cap disappears and reappears as Jet is holding him. (00:41:05)
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.
Revealing mistake: Near the end of the movie Mac is chasing Roth upstairs to get the deeds back. He shoots at Roth's bodyguard, who returns fire with a machine gun. But after the guard stops shooting, sparks still fly off of the door Mac is hiding behind.
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 scene in Silk's Casino, when the Chinese man jumps and does a kick hitting two different people, look closely at his hands. You can see that he is holding on to the wires.
Continuity mistake: During the fight, if you look closely, you can see the wire that holds the brazier in the air.
Answer: Mac says 'Asalamu alaikum Akhbar' This is the Islamic greeting and means 'Peace be with you'. Akhbar is a Muslim Name so Mac would have said this to him.
