Factual error: Before the assault by the criminals, the marshal says that they are unlikely to make it to Cedar City faster than an hour in that rain. The movie though is apparently set between Michigan (most of the license plates are from there) and Ohio (the main character's car plate, plus you can actually see GPS coordinates 41°42'57.2"N 83°41'19.3"W, which puts them near Toledo). Driving from Michigan to Utah (where Cedar City is) is just short of driving coast to coast, certainly no-one hour affair either way. (00:06:20 - 00:07:05)
Other mistake: Introducing the workplace to the new employee (Banderas), Vance says that the mall has never been updated because it has everything "Menswear, kidswear, ladieswear, cosmetics." The Italian dub misinterprets the last word (probably figuring it was 'medics'), and so the mall has the rather unlikely lineup; "Menswear, kidswear, ladieswear, doctors." (00:14:20)
Continuity mistake: Eddie is taken into the staff room to be introduced to the team and on the wall there's a big digital clock, making rather obvious the various takes combined in editing, creating a bunch of errors in continuity. When Vance starts mocking Mason, the clock is on 8:48, going back to 8:47 when Mason stands up from the chair. Ruby enters the room and the clock flips from 8:47 to 8:48 at the very first cut. (00:15:00 - 00:16:00)
Continuity mistake: After display the taser, Vance gets the uniform for Eddie. As he brings it to him, at the edge of the frame Mason turns around in his chair, casting an annoyed look around. He repeats the gesture in the following shot. (00:16:55)
Continuity mistake: When Vance does the military salute to welcome Eddie on the team, getting an icy stare and "Really?", in the two shots there's a glaring discontinuity in the position of Vance's epaulette, arched in the first shot, straightened out perfectly in the second. (00:20:15)
Continuity mistake: When the evil boss is trying to talk Vance into opening the door, in certain shots the gap between the doors is barely as wide as Ben Kingsley's head, in others the gap is much larger, and he is leaning closer to either side. (00:28:00)
Revealing mistake: The scene from above the shopping mall displays as a night scene, but when you look just a little closer, you see traffic (cars) driving around in the background with no headlights. Meaning, this was taken in the daytime and adjusted to look like it's at night. (00:29:44)
Continuity mistake: Jamie is holding at (toy) gunpoint Eddie; she has her thumb on the 'barrel', but it cuts mid-sentence to a close-up as she says "You don't cut me out and don't talk to me like a child", and her thumb is now on the 'fore-end' (if it makes sense with a toy weapon). (00:31:25)
Continuity mistake: In the basement, Eddie gives Jamie a bottle of water and a pink walkie-talkie. They switch hands in the one shot from Katherine Mary de la Rocha's left. (00:34:40)
Continuity mistake: Eddie and the others are looking at parking cameras; when Vance stands from his crouching position to say "Oh shit, they're gonna find Betty", he brings his hand to his mouth - not so in the following close-up on Banderas, where you see Vance's arm relaxed along his side. (00:35:35)
Continuity mistake: Midway through the scene when the guards discuss the intentions of the assailing force disabling their cars, specifically when Vance says "He is now" (in charge), Mason's bag turns around in his arms for no reason. He was clutching it with the colored size closer to his chest, and then it's the opposite. (00:36:05)
Continuity mistake: Close to the door of the staff room as he is on the verge of leaving, Mason during the scene has sometimes the tie of his uniform draped over the backpack he's carrying, while in other views the tie is straight down his chest as normal. (00:36:30)
Revealing mistake: When Banderas and co set ablaze the SUV dropping the flaming sofa on it, the man coming out of it is wearing a full fire retardant suit. (00:38:35)
Other mistake: Eddie, Johnny and Vance are under fire on the roof of the mall from a sniper who wields a single-action rifle that he reloads, manually, slowly, distinctly pulling the level in the close-ups, but that somehow when he is not in frame fires shots in rapid succession. (00:38:45)
Continuity mistake: When the sniper mercy-kills the driver on fire, he falls in a spot on the asphalt completely different from where Cung Le's men later retrieve the corpse from. (00:38:45 - 00:40:00)
Continuity mistake: Talking for the first time with Eddie, Ruby says "I can use a bow": Antonio Banderas' hand goes from his chin to being firmly against the counter right at the cut. (00:41:30)
Continuity mistake: Mason is in shock after killing the first bad guy with the automatic weapon. Eddie tells him "Okay buddy, I'm on my way", leaning with the left arm against the counter - but in the next shot, turns out his hand is on his knee instead. (00:51:25)
Continuity mistake: Looking at the food court from the security monitor, Johnny appears to have his left leg bent, but in the previous close-up of his dead body, the leg was straight. (00:54:10)
Character mistake: When we see the relative positions Eddie and Johnny have, Eddie appears to be the one that should have done the signaling to the patrol car instead. (00:55:40)
Revealing mistake: To kill the second and third guy at the food court, Eddie does a rather unlikely slide across the floor. His shirt is pristine even in the back, despite having sailed across soda. (00:57:40)
