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)
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)
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)
Continuity mistake: Eddie and Jamie have been talking in the dollhouse. The bad guy calls them on the radio, and Eddie answers. Jamie uncrosses her arms and puts the hands up along the legs to get up. Next shot, she has still her arms crossed. (01:03:25)
Continuity mistake: Vance shot the tank of the forklift the baddies used to break open the riot door, and it exploded in a rather bad CGI animation. The forklift itself looks undamaged after, and when later in the movie Eddie runs past it to momentarily evade Cung Le and go deal with the jammer, the red tank itself is still there. (01:06:55 - 01:13:00)
Continuity mistake: In the 'last stand' covering Mason and Jamie, Vance collapses, hit by the last bad guy he kills; his right hand drops the gun and the assault rifle on the ground is pointing at the red fridge. When he is shown again the position is similar, but different. (01:09:05 - 01:13:05)
Continuity mistake: Eddie puts the fake fed in a leglock and shoots him in the head; the other fed to his right has his arm bent or straight up depending on the camera angle. (01:19:50)
