Continuity mistake: In the famously later on added scene Ben Gardner's suddenly emerging head scares the hell out of Hooper the diver (as well as any viewer). What diminishes the effect is that the second close-up of the head looks nothing like the first, much creepier one.

Continuity mistake: Jack the "half-wolf" attacks a deer in the woods and bites its neck. But when he raises his head there's not one drop of blood anywhere (in his teeth, mouth etc). (00:49:40)
