Continuity mistake: When Ray first arrives at Devil's Tower and stops the station wagon, the broken fence post resting on the hood changes positions between shots. In the view of him through the wind shield, the post is lying straight, parallel to the length of the wagon. In the next shot, it is suddenly at an angle, even though the car hasn't moved.

Continuity mistake: When Roy says to Ronnie, "I saw something last night that I can't explain.," and he bridges his arms across the door frame his forearms are parallel to the ground. In the following shot, when Ronnie straightens up, Roy's forearm points upward. (00:36:15)
Continuity mistake: When Roy first encounters the alien ship at the railroad crossing, when the bright light comes on, he leans out of the truck window, and the right side of his face is exposed to the light. Therefore, it is the right side of his face that should have been burned. Subsequent shots show that the left side of his face is burned. (00:21:00)DavidCBohn
Continuity mistake: After Roy fills their kitchen with shrubs, bricks, soil, and chicken wire, Ronnie takes their three kids out of the house and into their station wagon. She tells her kids to lock the doors, but the driver's side door lock is up (unlocked). When Roy walks around the driver's side to speak with Ronnie, the driver's side door lock is now down (locked).

Continuity mistake: Barry is leaving his house, going towards the trees. Jillian looks out her upstairs window and Barry as well as the immediate area surrounding him are drenched in bright direct light, as if from a spotlight mounted on the side of the house. However, from an outside angle of the scene he is not bathed in light, and neither is the area he is in.Kit Sullivan
Continuity mistake: When Barry is taken from the house, just before that happens we see a grate get blown out of the floor and it lands on its side. In the next scene the grate is back in the hole, but at an impossible angle, even if it fell in.
Continuity mistake: When Richard Dreyfuss is building the model of the Devil's Tower in his living room, behind him in the sliding glass doors you can see that it is raining, and when he turns around and walks to the door to look out, it is now sunny, and people are out side mowing the grass and children playing.
