Continuity mistake: Reba gets out of their truck at the compound and looks through the binoculars - in the foreground you see the tractor and trailer they use to escape are very close together, or are attached already. When Kevin Bacon and the other guy figure out to use it, the camera pans around and the tractor and trailer are 60-100 feet apart.Joseph Greene
Continuity mistake: When Val and Earl are relaxing with a couple of cold ones after they bury the trash, Val's recliner chair changes. From the side it is a brownish-rust color cloth material. In the next shot, from the front view, it is greenish leather. This scene takes place after Rhonda's near miss with the graboid but before the first guy, old Edgar, is found dead.
Continuity mistake: When Val is getting the fuse lit on his bomb to throw to the last Graboid, we see his hands separated, one holding the bomb and one holding the rope. The camera angle changes to a close up of his hands, where they are now both holding both the bomb and rope. (01:24:50)DavidRTurner
