Continuity mistake: When Jane shoots the guy in the trailer, there is no blood on the wall behind him as he slides down. When she approaches him and removes the shotgun, streaks of blood appear.
Factual error: Ben states that the temperature is -6'F. When the officers drive to Matt's camp the gravel road is quite slushy. This would not happen in freezing temperatures. (01:03:10)
Cory Lambert: Wolves don't kill unlucky deer. They kill the weak ones. You fought for your life, Jane. And now you get to walk away with it.
