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)
TormoniContinuity 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 Carter and Lee meets on the yacht some guards comes and tells Ricky Tan is waiting for them. Carter lifts up his arms fighting style. When it cuts his arms has changed position. (00:31:55)
MortugContinuity 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.
Answer: Although it's never shown, it was probably Ricky Tan's henchmen. Lee and Carter were outnumbered and decided to give up. After the fight, they were dropped off in the middle of a busy highway with no clothes on as a way to add insult to injury.
