Revealing mistake: When Chris and Jackie are singing the Beach Boys song in the car, look at the steering wheel. When Chris Tucker begins to dance for a brief moment you can see that there is no key in the ignition. (00:02:30)
Continuity mistake: When Carter is singing karaoke, first you see the girls beginning to join him on stage. In the next scene (right after the scene with Inspector Lee's reaction to Carter singing), you see Carter dancing with a DIFFERENT group of girls (it lasts a couple of seconds). Then, when Lee is calling out Carter, the original dancers from the first scene are back. Use the tall Chinese girl wearing the pink dress on the right side of the screen as reference in the first scene, then she disappears in the second scene and reappears in the last scene. (00:06:45)
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: 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: When Jackie and Chris are hanging from the bamboo shoot Chris has hold of the shoot in his left arm first then in the next shot it has changed and now he holds it with his right arm. (00:12:45)
Other mistake: When Chris Tucker and Jackie Chan are fighting in the massage parlour, Chris Tucker is able to fight and do all sorts of moves with only a towel wrapped around his waist that magically never falls off. (00:18:30 - 00:20:20)
Continuity mistake: In the police station, just before the explosion that supposedly kills Carter, we see Jackie with his shirt untucked on his way to his office. As he falls to the ground after the explosion his shirt is miraculously tucked in. (00:22:25 - 00:24:00)
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)
Continuity mistake: After the detectives get the bag from Isabella, she shows them her badge in her bra, but before they get the bag from her, there's no badge in her bra. (00:39:15 - 00:41:55)
Suggested correction: True we don't see Isabella wearing a badge in her bra when Lee and Carter kick in her door, but when she arrives at the top of the building wearing her robe, she most likely put her badge on before following them.
Factual error: When Carter convinces Lee to head with him to L.A, apparently the plane they are leaving is a Boeing 757. When they arrive it is evident that they reached their destination in a Boeing 747-400. (00:39:43)
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: When Lee and Carter are buying clothes from the guy at the store, a woman in black pants starts to come down the stairs behind him, but after the camera turns away and cuts back to him, the woman that was coming down the stairs has disappeared. (00:57:15)
Factual error: When Jackie and Chris are at the Casino. Chris goes to play craps and throws $100,000 down for chips. The croupier give Chris two stacks of 20 $500 chips, which equates to only $20,000. (01:01:35)
Suggested correction: He wasn't really focusing on how much money he threw. Carter was creating a distraction for Lee so the Security would not see him sneak in to find the plates.
Revealing mistake: When Inspector Lee was running through the casino, his hands are bound together with tape. When he tumbles across a gambling table, his hands come apart. When he completes the tumble, he quickly puts his hands together again. (01:09:00 - 01:10:15)
Continuity mistake: When Zhang Ziyi shoots Rosalyn Sanchez in the casino office, Sanchez is facing away from her. You see no blood on her back. Later, when Sanchez falls into Jackie Chan's arms, there is still no entry wound from behind and no blood. When he spins her around, you see a bullet hole in the front of her arm and blood smeared on the front of her arm. (01:10:45 - 01:12:40)
Continuity mistake: When Carter and Zhang Ziyi are fighting, Ziyi's shoes change from high heeled in the first shot to black running shoes in the shot when she falls from the pool table. The shoes also change to medium heeled while she is on the pool table. (01:12:00 - 01:13:20)
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)
Visible crew/equipment: When Carter is fighting Zhang Ziyi, she thrusts a sword into his coat. For a split second, there is a shot where a man is crouched down behind the statue on which Carter is against, looking up at Carter and Zhang Ziyi. (01:13:45)
Continuity mistake: At the very end of the film when Jackie Chan and Chris Tucker are saying their final good-byes Chris Tucker is wearing the strap to his bag on his left shoulder and if you look you will notice in almost every scene even in the mistakes during the credits the rubber thing on his bag is there and then in the next scene the rubber thing is gone, and during the credits the rubber thing is back but the strap is crooked with the rubber thing there. (01:20:00)
Continuity mistake: When Carter and Zhang Ziyi are fighting, Carter is wearing alligator skin shoes (brown). However, when Ziyi thrusts the sword at Carter and Carter falls back on a chair raising his feet, you see him wearing black running shoes with a white sole.
