Continuity mistake: At the end of the film, Nicolas Cage assaults the enemy compound with two Glock 17s. When he exits the compound and shoots at the boss's car, which is pulling away, in one shot he is firing a SIG P226, but in a later shot is using a Glock again. (01:28:55 - 01:29:45)
Continuity mistake: When the soldiers rip off posters that depicts racial images of buffalo soldiers, the board underneath remains blank. Later in the movie, when they are about to escape the town, the board is shown with tattered old postings again.
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: In the beginning, when Michael Berg is sick on the street in Neustadt and is leaning on a wall to throw up, he's near a closed door and is positioned to the right of that door. Next shot, from inside, shows the door now open and he is leaning to the left part of the door. (00:03:15)
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: 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 Chris drives up to Edgar's house, his windshield is dirty but suddenly clean thereafter. (00:11:37 - 00:12:57)
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: When the pea-soup is first taste tested, you can see close up that it is under C. Once it zooms out to the room, it seems B and C have changed places. (00:07:20)
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 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: In the scene where the Buddies are wondering how their kids are, we see the kids really upset about them not being home and we go to Alice trying to decide what to wear. In the next shot, the dresses she's holding change places.
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: 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.
