Corrected entry: When Val and Earl meet Rhonda for the first time she asks if there is any drilling, explosions etc. and they say no. She explains the graph's readings are strange and thought it could be because of possible works going on. A bit later as Val and Earl are leaving Perfection they come across 2 workmen drilling the road.
Corrected entry: Rhonda has light colored pants on earlier. When she is on the water tower, she appears to have new jeans on.
Corrected entry: Rhonda does a pretty good job on keeping her truck on the road, especially considering her head is below the wheel.
Corrected entry: When Valentine grabs Mindy off the pogo stick, you can tell it's been stuck into the ground so the actress can stand on it and be ready for Kevin Bacon to grab her (as opposed to Kevin Bacon grabbing her while she's bouncing). After she's grabbed, you can see the pogo stick shake back and forth without falling over.
Corrected entry: There is absolutely no way that a sheep farmer could survive in a desert environment. The farm is shown to be set in scrappy scrubland and sand - nothing that a sheep could eat is shown. (Apart from this, the heat would kill them.) Cows maybe - they could eat the scrub. Grass eating sheep, never.
Corrected entry: When Old Fred is eaten, he's holding a hoe. When Val and Earl find him, the hoe is nowhere to be seen. It's been established that the graboids spit out things they can't eat (the generator, the bomb) but we see a wide area around where Fred was, and no sign of the hoe. Yes, it could have been spit VERY far away, but in the other instances the objects are still in the vicinity of where they were eaten.
Corrected entry: When Burt and his wife are shooting the Graboids in their basement, he tosses her a magazine; he is kneeling and we see it tossed slightly up and then starts falling in the air, no more than 4 feet above the floor. But the camera angle changes and she catches it falling from her head height - she is 5'6" - so it magically rose about 18". (01:00:00)
Corrected entry: Why is it that Rhonda, Val and the others are safe when in their cars? Earlier in the film we see a graboid drag a large station wagon completely underground in order to get at the occupants. If they can do that then, why can't they do so with the cars used by our heroes to escape their clutches?
Corrected entry: When the heroes are on the roof and they send the lawn mower off as a diversion, you can see it would crash into some building. In the next shot, it is back on the road. (00:21:02)
Corrected entry: When Rhonda is jumping from shelf to shelf in the store, she slips and falls in one of the shots. You can just see her feet stumbling as she lands on the materials on the top shelf, but the shot ends before she falls all the way.
Corrected entry: When Val, Earl and Rhonda are stranded on the boulder the camera shows a wide shot of the entire area, then fades to dark. It's clear that the nearest boulder to theirs is at least 25 feet away. The next morning the trio "pole vault" between boulder to boulder with 7-8 feet long poles. The boulders magically became much closer together overnight. (00:38:45 - 00:40:40)
Corrected entry: The radio that was taken up onto the roof was not battery powered and should not have continued working because it was no longer plugged into an electrical outlet.
