Other mistake: When Darry is in the basement under the church, Darry is laying on the floor surrounded by a circle of sunlight appearing through the pipe. Then follows a series of cuts between Trish at the open end of the pipe, and Darry. Why do we not see a silhouette of Trish on the floor rather than a perfect circle of light?
Continuity mistake: The police station that they stop at is in a very out of the way rural community with only a few people in the jail. However, once the demon enters the jail and the alarm is sounded there are at least 20 cops on duty - all at the station in the middle of the night, in the middle of nowhere.
Continuity mistake: When the main characters visit the house of the old woman with the cats, she comes out and aims at the monster with a double-barrelled shotgun, and fires one shot. Then when she goes back into the house, two shots can be heard in quick succession. She must have re-loaded the empty barrel quickly...
Continuity mistake: There are at least two different 1960 Chevys used in this film. There is a noticeable difference in the front bumpers. Notice the front bumper area just below the headlights. The first car used has a plain straight bumper, the second one has little chrome trim riser mounted just below the center of the headlights. The second one first shows up at the cat lady's house. The lower tag pan also changes.MonnieWeb
Plot hole: The whole point of Darry going down the pipe near the beginning was because he couldn't see the bottom of the pipe. However, Trish can make out his shock when he notices the body. Darry's flashlight is not providing the light in this scene as the light is coming from the tunnel. (00:21:05)A Demon
Continuity mistake: When they are in the dirt field one of them says, "Its getting dark." But in later scenes it is lighter and then it gets darker. This happens a few times.
