Continuity mistake: In the scene when Nick Chen (Chow Yun-Fat) talks to Jack (Jon Kit Lee) at the NYC Correction, the shot facing Nick shows him grabing Jack's face by the chin. The next shot, facing Jack, shows Nick's hand around Jack's neck. The final shot facing Nick again shows his hand back on the chin. (00:58:50)
Continuity mistake: In the scene where Amelia is driving the truck full of policemen to the scene of the second (Mrs. Rubin) murder, the shot changes a couple of times before it settles looking through the front windscreen at Amelia. Through the rear windscreen of the truck, you can clearly see the highway and all the cars on it behind them. Amelia turns the steering wheel sharply to the left, and you hear the screeching rubber-tyres-on-tarmac noise as if she really had swerved left, but the scene of the highway behind them seen through the rear screen does not alter at all - as if she was just going in a straight line all the way.
Continuity mistake: When Maggie talks to Eddie Bo Smith Jr. (the Chicago cop) outside the meeting of "receivers", you can see the cop's breath when he speaks, but not Maggie's.

Continuity mistake: At the end, when Madeline is kicking dirt onto Harry when he is lying in the hole, the amount of dirt on his shirt changes from shot to shot.
Continuity mistake: After Hall has been shot in the leg in the simulation of LA 1937 the hole in his trousers and his injury disappear, as seen in the fight sequence at the pool. Hall even uses his leg to hit the bartender in the stomach, what would have made this very painful if he had been shot there.
Continuity mistake: At one point when Nick and George are driving the the Porsche, their seat-belts alternate between being on and off between shots.
Continuity mistake: When Libby goes to the BMW dealer, the dealer says the address is 20 Oriole Terrace. When Libby is driving down Oriole Terrace, she passes a house with four digits in the address.
Continuity mistake: The whole premise of the movie is a paradox: The main character's colleague thinks the main character has inherited a fortune, and the colleague wants that money which is why he tries to frame him by making him steal some fake drug money. BUT why would the main character run that risk, agreeing to steal the drug money? If he HAD inherited a fortune, he doesn't need a risky ten thousand bucks now, does he? Surely his friend might work out something was up when his supposedly rich friend agreed to run a risk to earn a comparatively small amount?
Continuity mistake: When Heather first picks up the bundle of sticks she carries them to the river. During this she steps over a log on the ground and if you look closely you can see the black bag containing the guy's teeth fall out but when Heather opens up the bundle it is still there. She couldn't have put it back herself.

Continuity mistake: When Guy Pierce is offered a nut by Jeffrey Jones, Jeffrey Jones picks up a book in order to smash the nuts.

Continuity mistake: During the scene when they are trying to bring Mr. Leniog into the rear of the door we hear them trying to open the door from the inside, shaking it rather violently. From the outside shots we hear the door rattling but it's not moving at all like it is from the inside shots.
Continuity mistake: The camera goes back and forth between Vann and Ferrin when they are having a conversation in the post office. Ferrin's hair is very frizzy the whole way around her face (and a total mess). There are some strands of hair that dangle from her scalp which aren't always the same. Perhaps more noticeable is a clump of hair on the left side of her head that intermittently sticks out sideways a few inches. When there is finally a rear view of her head, Ferrin's hair is suddenly neatly combed back in a bun with little or no frizz - only the strands that dangle in the front stay the same.
