Continuity mistake: The first time Sherlock shows his camouflage suit, its brown colour changes between the first and second shot. The first one matches exactly that of the room, but the second doesn't. Clearly the first one was achieved with a green-chroma-suit, and the second angle was a coloured fabric.
Continuity mistake: When Boyle arrives in his police car at the house where McCormick is murdered, he turns off his engine and his windscreen wipers are pointing towards the sky. In the next shot you see the windscreen wipers in their normal position again.
Continuity mistake: In the restaurant scene Nathan has a glass in his right hand on the table. The next shot appears the glass on the table without his hand, and then again in Nathan's hand.
Continuity mistake: When a guy brings flowers to mourn for Mitch's wife, he is in the kitchen, stands up and runs to the door. When the angle changes, a frame later, he repeats all the previous movements.
Continuity mistake: Multiple scenes: On every exterior shot of the train, you can only see one row of windows across the upper galley section. However, whenever there is a scene shot on the upper 'galley' level, there are two rows of windows, one right above the other. The external shots were filmed using a Chicago Metra train (which uses 'bilevel' galley cars), the internal scenes were filmed on a set in Montreal, Canada.
Continuity mistake: When Justin gets a text from Mike's cell phone, it shows a close up of the screen. In the "to" box, it says Nikki although it's Mike's phone.
Continuity mistake: Cutthroat awakes and finds a guy tied up in a chair. After talking for a moment, a sound and light show up behind Cutthroat and he turns around. The side of his face is lit up when he does. It cuts to a different angle and now his face is not lit up. (00:03:30)
Continuity mistake: When Valerie's father was the werewolf, his right paw was burnt. Then, when we see the hand later, there isn't a scratch on it, but again later, we see that it is, once again, looking burnt.
Continuity mistake: The women dealing with the table of drugs are dressed in their underwear. One woman in her underwear brings two glasses and alcohol to her boss. She leaves in a dress.
Continuity mistake: When Nadya escapes with her son from the monastery she drives the car through the doors, and the driver's side of the car sustains substantial damage at the side of the hood with the side-view mirror completely broken off, but during the chase there's little damage to the car's body and the driver's side-view mirror is now dangling at the side.
Continuity mistake: When Lucy comes home at the beginning of the movie she quickly buttons the top of her dress. While eating dinner, it is open and then buttoned again between shots.
Continuity mistake: At the end of the movie, when Liam Neeson looks around at the wolves approaching from the forest, the black frostbite mark on Liam Neeson's face is on his right cheek instead of his left cheek. (01:50:00)
Continuity mistake: In the opening scene just before Victoria descends into the cave, she's wearing two headlights, the bigger one is on her right side and the smaller one is on her left side. In the next scene while she is talking to Josh, the position of those two headlights changed. (00:15:10)
Continuity mistake: When the nurse is giving Liam Nelson the address of the investigator, in one shot she's writing the note with her left hand, and in the next shot, she has the pen in her right hand.
Continuity mistake: At the end of the movie when the girl and guy are boarding the submarine, the camera switches to a view where you can see an apartment complex in the background. If you look towards the top you can see someone standing at the balcony and then they move off towards the balcony door. In the next shot the person is gone.
Continuity mistake: Bill Haydon is on a call with the Hungarian embassy. He's holding his phone in his right hand talking on it, but then slams it down with his left hand.
Suggested correction: Watch the scene, he lowers the receiver to speak to Jerry and his hands come together on the receiver, the camera cuts to Jerry, then back to Haydon hanging up the phone with the left hand, closest to the cradle. Watch it again, seems to match correctly.
Continuity mistake: Vincent has brown hair. When he has the spike driven through his head, his hair is blonde.
Continuity mistake: In the reaction shot to the "Everybody wins and everybody lives" line when Kyle offers to cut the diamonds, Nicole Kidman lacks the long bangs that she is sporting in the rest of the scene. (00:22:30)

Continuity mistake: Right after Sanderson hands Kemp the itinerary for the next day's events, Sanderson places a pen and a glass ashtray directly on top of the folder lying on the table in front of him. In the next shot, the ashtray is covering only a small portion of the corner of the folder, and the pen is lying beside it.
