Continuity mistake: When Vaines takes out his gun whilst using the camcorder's night vision mode, the condition of his thumbnail in the close-up shot of him taking out his gun looks completely different to how it is in the close-up shots of him holding the camcorder. In the gun shot it looks dirty and unkempt but looks clean and pristine in the camcorder shots.
Visible crew/equipment: A crew member's bald head can be seen peaking in the bottom right hand corner of the shot as the sheriff moves his torch around. (00:32:00)
Continuity mistake: In the scene where Sarah and Ellen are attacked in the pool of poo, Ellen stabs one of the creatures in the neck with a hair pin. Sarah ends up with blood all over her face, her neck and her (white) jacket, moments later there is hardly any blood on her, which later reappears.
