Continuity mistake: When Carter is fighting Zhang Ziyi, after she stabs him in the chest with her sword and pushes Carter and the statue over, you can see that the statue is holding a plain wooden dowel. It doesn't have a sharp blade on it that you see in the next shot when it springs up and knocks her out. (01:13:40)
Continuity mistake: When Jackie Chan is in his car after he thinks Chris Tucker is dead he plays the P. Diddy song 'Ill be missing you'. When he makes a call to the man it's at the start of the song. When the camera switches back to Chan at least a minute of the song has passed and when it switches back after going to that man again its near the end of the song in about 20 seconds.
Continuity mistake: When Lee asks the Chinese man behind the desk where 'Zeen' is he runs off. He then goes through a door and then through another door and you see him run into the yard outside. But when the shot changes to the yard you see him run through the second door again.
