Continuity mistake: Mike has a shotgun as he is trapped in the hearse. He then blows the window to pieces and jumps out, and the shotgun is not in his hands. Then when he hits the ground, the shotgun is back. (01:02:40)
Visible crew/equipment: After Reggie touches the metal poles, he goes flying backwards. As he hit's the floor, you can see a thick white rope attached to his left foot. (01:11:10)
Audio problem: When Mike is outside, in the strong winds, yelling "Jody," his mouth doesn't match up with the audio, and sometimes his mouth doesn't move at all. (01:12:00)
Revealing mistake: Reggie runs out of Morningside, and then as he runs down the stairs you can see the shadows of two crewmembers cast on the steps beside Reggie's shadow. (01:12:20)
Continuity mistake: When the Tall Man is chasing Mike, Mike treads in a pool of mud, and then his trouser legs get covered in mud. Moments later, as he continues running, his trousers are clean. (01:17:30)
Revealing mistake: When the Tall Man falls into the mine shaft, but grabs onto the ground around it, the whole ground around him wobbles badly. (01:18:40)
Revealing mistake: When the maintenance man grabs mike and won't release him, you can tell Mike has a mouth full of blood that is used when he bites the man's arm.
Other mistake: When Jody finds the dwarf in the car and recognizes it to be his deceased friend Tommy, he has a quick flashback to Tommy in the coffin and the exact moment Tommy was murdered. But the second flashback makes no sense, Jody never saw Tommy being killed and was told by Reggie that he committed suicide.
Revealing mistake: When the silver sphere flies into the guy's head, if you look closely, the wire attached to it is visible. This was shot with the ball being pulled away then the footage was reversed.
Continuity mistake: At the beginning of the movie, when the girl is having sex with a guy, her legs are parallel to his, then it cuts to her sitting up on him. It's not physically possible for legs be flat on the ground whilst sitting up like that.
Continuity mistake: A 1977 Oregon license plate is on the 1971 black Barracuda - 9GR 635, later that same plate is on a VW, when Mike flies out the back window.
