Factual error: After the first shot of Carter as he is walking up the stairs of the building with the bamboo scaffolding, the New York Life Building is in the background. This scene is supposed to take place in China. (Scenes were actually shot in Hong Kong, China, but the NY Life Building has famous distinctive architecture.)
Continuity mistake: When Jackie is hanging from the bamboos at the beggining of the film,the distance between his hands changes from wide open to up close one to another as the camera changes positions. (00:11:30)
Continuity mistake: During the gangster bar scene early in the film, when Carter tells Lee he is a star, one of the girls Carter was dancing with has her hair straight down. After Lee tells him they are in a gangster bar, her hair is suddenly smoothed behind her ear and lying over one shoulder. (00:07:40)
Continuity mistake: At the end of the movie, in the airport scene, Carter and Lee are saying their goodbyes. IF you look over Carter's shoulder, you see a girl in a green sweater with white sleeves walking away from him, the scene switches back to Lee, then when it switches back to Carter, you see her starting back at the exact same spot walking back again. This happens several times.
Continuity mistake: When Jackie Chan and Chris Tucker are back in L.A. and go to the Chinese restaurant to see Kenny (Don Cheadle), Kenny's hair is pulled back in a pony tail. The position of the pony tail changes several times throughout the scene - sometimes it's over his right shoulder, sometimes it's hanging down his back. (00:45:50)
Continuity mistake: Carter and Lee enter the back parking lot witnessing Zhang Ziyi and crew hauling items into the truck. The shot where Ziyi, Carter and Lee confront each other, the lighting shows pimples on her forehead. The next continuing scene where she is in the back of the limo on the highway, her forehead is clear of pimples.
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.
