Continuity mistake: When Ryan Reynolds is between the two hospital beds, preparing to pull the plugs, there are three wires he grabs to our left (two white and one black). He yanks all of them out (along with another white one to our right) and no plugs remain in the red outlet cover on the wall. But in close ups, as the other agents are banging on the door, we see the lone black wire is still plugged in. (01:40:15)
Continuity mistake: When the police rush into the bathroom towards the end of the movie to capture Sir Ivy, you'll see that as they start to lift him up his left eye is completely covered in blood but when they lead him out of the room is eye is open with way less blood than before.
Continuity mistake: In the scene which has a room full of passed out women, the topless girl laid on the floor has her arm over her chest. The arm moves to next to her side between shots.
Continuity mistake: When Hugo is shot by Zoot, a spatter of blood comes from the exit wound, hitting the wall. When Zoot puts on Hugo's jacket, however, there is no bullet hole in the back of it when the bullet left.
Continuity mistake: After saying "We've been here for 16 hours.", Ray Liotta's character is shown in close-up, looking toward Ryan Reynolds. But the wide shot shows he is staring off to his own left, into the camera. (00:02:00)
Continuity mistake: The topless girl on the floor has her legs bare in one shot, and covered in the next.
Continuity mistake: As the exterior shot of Lake Tahoe advances, the cameras closes in on the roof of a hotel. Beyond, another hotel's facade is in shadow as the sun is behind it, off to our left. The shot sinks through the roof of the closer hotel so our view is now from within the penthouse, but now the facade of the second hotel is in full sun, the light is now coming from the left, but behind the camera. (00:18:40)
Continuity mistake: Just after Ryan Reynolds pulls the plug, he's sitting upright. As the agents rush towards the door at the end, we can see in a brief shot that he is slumped with his head in his hands. We then cut to a shot inside, and he's sitting upright again.
