Continuity mistake: In the last scene, Tanya gets her arm cut on a piece of glass in the window by Charles, just before he turns to fight a cop. In the next shot the glass has disappeared from the window completely.
Factual error: Ron Pearlman plays a state police captain named "Captain Soames". On his uniform he has both captain's bars on his shirt collar and sergeant's stripes on his upper shirt sleeves. He would not hold both ranks and would not keep the sergeant's stripes on if he had been promoted to captain. He also would have gone through the rank of lieutenant (one bar) prior to becoming a captain, so he would have had plenty of time to take the stripes off his uniform.Robert Sullinger
Revealing mistake: At the end, when the monster grabs the sheriff and throws him across the front yard, the sheriff lands on his back and his right arm falls into a beartrap. The trap snaps and the sheriff screams in pain, but only one jaw of the prop beartrap actually snaps into vertical position (the opposing jaw remains flat and doesn't move). A real beartrap snaps both jaws together vertically. So, the sheriff's hand doesn't get snapped at all.Charles Austin Miller
