Continuity mistake: On the subway while John and Cassian eyeball each other, from the front there's no-one in front of Cassian, just a guy in a hat off to the side. But from the back, another man appears between them.
Suggested correction: You can see the edge of that guy cut off on the edge of the shot he is there, that grey hair and that same jacket.
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: As Dom escapes the grappling hooks, the cars get wrecked. He crawls out from his car and the silver briefcase is within arm's reach, right next to double yellow lines. Only problem is, in the earlier shot from above, he crashed nowhere near lines like that, and there was no briefcase there either.
Visible crew/equipment: When Baby is in the car that he stole after running away from the mall center and he crashes against the back of the pickup, you can see the cameraman and the crew member on his left reflected in the rear window.
Continuity mistake: At the start Edgar smashes his car up and kicks his window out and jumps out leaving a bit of glass in the window frame. However after the camera changes, the 2 bits of glass have disappeared. (00:01:05)
Continuity mistake: When Shawn first holds up the jerky to distract the guard dog, he's holding the torch in his right hand and the bag of jerky in his left. We cut to a wider shot and the items have instantly switched hands. (00:26:50)
Continuity mistake: Michele Riondino has just killed the snitch and is going after the witness, a Chinese woman. He holds her at gunpoint; she does not move, but in a shot she has hair in front of just her left shoulder, both shoulders in the next. (00:30:30)
Continuity mistake: Jon is scarfing down a burger at the Tommy's kiosk while Ponch is jerking off in the bathroom. He gets a mess of mustard all over the shirt, down to the belt, and to the pants. The pants stain vanishes right away for the remainder of the scene (but shows up later in another scene). (00:35:40)
