Continuity mistake: There is a modern coffee thermos container on the sink by the window during a scene set in the 1930s. In the next shot, it suddenly disappears. (00:46:25)
Continuity mistake: When the first guy out of the main 3 is dragged to the hunting range (after having his spine exposed and meat cut off), he falls backwards into the snow and when he sort of rolls over, there is snow all over his exposed backbone and flesh but when he stumbles and gets up, there is no evidence of snow whatsoever.
Continuity mistake: The neighbors are dripping wet as they get out of the hot tub, yet they don't drip any water when they get onto the trampoline.
Continuity mistake: The getaway car has its path blocked by the police on one end of the road. They U-turn and try to escape the other way. During this sequence there are POV shots from inside the car that were filmed at a very different time; the natural light is completely different. (00:02:20)
Continuity mistake: 50 Cent goes through the window onto the floor below. There is glass and debris everywhere. Our heroes run past him later and there is no sign of the window debris.
Continuity mistake: While Michael Malone and Gen. Patton are discussing what just happened in the subway, in the background, two ACLU zombie-lawyers begin chasing an ambulance as it drives away. After a brief cut away, we return to the same view - and the same zombie-lawyers chasing the same ambulance.
Continuity mistake: When we first see Agent Holloway viewing the crime scene photos taped to the wall, he is facing camera looking at transparent pictures on a transparent wall (as if we are behind that wall, seeing through it). When the angle changes to see the Agent from behind, the photos are now paper photos on a normal, opaque wall and the pictures are arranged somewhat differently - most notably to Holloway's right near the top where two wider photos are vertically aligned atop and below each other in the second shot when they were misaligned in the first shot by nearly half their width. The transparency versus opaque materials issue is a stylistic choice of the director and not a mistake, but the mismatched alignments is a mistake. (00:11:25)
Continuity mistake: Jim, driving Scott home, is smoking a cigarette that disappears before he slaps Scott the second time. There is no smoke in the vehicle that would suggest Jim temporarily placed the cigarette in the ashtray. (00:15:09)
Continuity mistake: After having sex on their 2nd date, Lawrence and Janet are talking in bed. Her arms move instantly from over her head to her side.
Continuity mistake: During the scene that Bo and Sam kiss, his hair changes between shots. From the back, his hair is completely pulled back. From the front, his bangs are down. (01:27:20)
Continuity mistake: When Omar Sadiki is escaping from agent Ferris, a cream Cherokee chases him and a black Kia SUV tries to intercept him as well. This black Kia takes a shot that completely shatters the windshield, but seconds later it crashes and the copilot is expelled through an undamaged windshield.
Continuity mistake: When Chris drives up to Edgar's house, his windshield is dirty but suddenly clean thereafter. (00:11:37 - 00:12:57)
Continuity mistake: Right before Ben runs over the skunk, he's wearing goggles, but when you see him on the ground right after crashing, he is not.
Continuity mistake: When Rincewind and Twoflower are at the Edge, Rincewind tells how he only knows the one spell from the Octavo and how he got it. In several shots of Twoflower the clouds in the background change drastically, often between one- and two-seconds shots of Rincewind. The clouds are almost motionless in every shot, so they could not have drifted that fast so suddenly.
Continuity mistake: When King is fighting with Lazarus in the bar, Lazarus gets blood near his mouth like you get when getting hit in the face. But when they fight near the white door, the blood is gone. (01:13:00 - 01:18:00)
Continuity mistake: While on a dirt road, the GPS tells them to turn around when they can. The car then starts to turn left. In the next cut, the car is turning right.
Continuity mistake: In the scene where the drama teacher is in the copy shop trying to decide what color paper to buy, his hand keeps moving between shots. Every time the shot is from the copy shop side of the counter, the drama teacher's right hand is in front of the blue paper. But every time the shot is from the drama teacher's side of the counter, his right hand is in front of the orange paper.
Continuity mistake: When Annie is taken to the truck (in Mexico), she has no coat on and a gag in her mouth. When they reach the cantina, she is taken out of the truck wearing a brown jacket and no gag, but as soon as they show her inside the cantina, she once again has on no coat and is gagged.
Continuity mistake: In the scene at the end of the film at his grandfather's empty lake house, Simon first unloaded the wooden Christmas figures from his duffel bag onto a pile of firewood on the dock. He then went into his grandfather's workshop and sawed the scroll off of his mother's violin. With his phone, he took a picture of the severed scroll in his hand with the dock in the background, but the dock was empty.
Continuity mistake: The first night in Genova Mary cries and her father comes to hug her. Her hair keeps swapping back and forth from sweaty and stuck to the forehead to loose.
