Continuity mistake: In the beginning with the campers as the guy says "You were right, this is definitely better than being," the girl is holding her cup with both hands around it. When it cuts, she is holding the handle of the cup. (00:00:35)

Continuity mistake: In the scene where Ryan tells Cooper to shoot the dog, Ryan pushes the gun parallel to Cooper's chest, the barrel is horizontal.

Continuity mistake: When Joe is complaining about missing the football match and Sgt. Wells says "Yeah, well it's nothing like this at all, is it Joe?", Wells is holding his hand under the front part of the machine gun. When it cuts we can see him resting his hand on top of the front part of the machine gun. (00:08:20)

Continuity mistake: When Cooper locks himself in the bedroom towards the end of the movie and looks for a way out, the wash basin does not sit on its support, a gap can be seen, but the next time it's seen it sits flush with the support.

Continuity mistake: When Terry vomits on Ryan, some of the vomit on Ryan's face appears or disappears depending on the shot.
Continuity mistake: In the scene where Ryan transforms into a wolf, as he is thrown across the table, the sword is knocked onto the floor. In the next shot the sword can be seen back on the table, before it returns to the floor.
