Other mistake: When Larry Crocket runs out of the house in his underwear and gets attacked by Barlow, later when the police find him his clothes are in the car. How is that possible when he ran out of the house with his clothes still inside?
Other mistake: When Father/Priest is talking with Mark and his parents around the table about Mark and Danny's friendship, the kitchen light flickers, followed by the phone ringing, which Mark's father gets up to answer. But then hesitates a moment, like the actor knew what was going to happen, ruining the suspense just as the house begins to 'shake', things crashing. Then the Demon grabs Mark too lightly, possibly to avoid hurting the Mark actor, as Straker speaks.
