Continuity mistake: When we first see John, he is in the police shooting range. He has on protective head phones which he takes off and sets on the table in front of him as the other cop comes in. He and this cop talk about Jack, and when they finish, they shake hands. The mid range shot of them shaking hands shows the head phones still on the table. It then cuts to a far shot and now the head phones are gone while the two finish the hand shake. Careful which table you are looking at, as the angle makes it confusing. The head phones were on the table with the red thing on its left side. (00:06:50)Quantom X
Continuity mistake: During the chase with the blue van, it keeps changing model. Starts with a van with high roof, than low roof, high roof again. And this goes on and on.
Continuity mistake: When being shot at by the helicopter in the hotel room, the scaffolding that John and Jack make a run for is not visible from the outside shots (to the left of the building).
Continuity mistake: During the opening chase we have a long shot of the blue van turning left onto the main road next to the river - the next shot is the armoured truck doing the same, but in close up the road layout is completely different, and yet they are right behind the blue van.
Continuity mistake: Just after John asks Jack if he is "gonna cry a little" before he pulls the bolt out of him, Jack leans his head back. The next shot, Jack's head is down. Throughout this scene, his head keeps changing position between shots. Also noticable right after John says "You shot?" (00:58:25)Quantom X
