Revealing mistake: At the end of the film when John Moon is digging a shallow grave for the dead girl (who has been dead for days, and spent additional days in a freezer also). You can see the dead girl breathing by the way her arm is moving on her chest. (01:46:00 - 01:47:00)
Continuity mistake: At the beginning of the film when the girl is shot, in the close up there is no debris on her face, but the next wider shot shows her face covered with dirt and other bits of debris.
