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.

Factual error: Rios records a message for her daughter on her mobile phone. The phone is a Nokia N81. The film is set two days after the first one, in 2005. But the N81 wasn't released until 2007. (01:02:00)

Ed Oswald: My granddaddy used to work down there. One time, him and two of his buddies broke into a whole new cave system. Really big. Company bosses figured there should be some rick picking to be had, so they sent my granddaddy back down to have a look-see. He never come back. Folks reckoned they must've broke clean through into hell. The devil was mighty pissed.

Cath: Is it okay?
Dan: You know what's good? Modern mines have metal props. Miners prefer these old wooden ones.
Cath: Why's that?
Dan: The metal ones don't give you any warning when they're about to go.

Sarah Carter: Those things were coming for us, so I hurt her so I could get away.
