Corrected entry: Val climbs up a metal electricity pylon to try to help Edgar. They are in the middle of the desert at noon (note the shadows) - the metal of the pylon would be unbearably hot. Val would be badly burned, but he doesn't even wear gloves.
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".
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.
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.
Corrected entry: When Rhonda has just dug a hole to bury the sensor, the shovel is spotless, but it should have at least been dusty from digging.
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.
Corrected entry: When Val and Earl and trying to get away in the truck, Earl scolds him saying "You're gonna burn the clutch!" In earlier scenes you can see that their Mazda B-series truck is an automatic.
Corrected entry: Since Carson City is so close to Perfection (as evidenced in Tremors 4), why didn't Val and Earl make a run for there, instead of Bixby? Carson City was due South, whereas Bixby was to the Northwest, in the direction the graboids were coming from.
Corrected entry: When Val is being lowered from the roof into the store to get the radio, he snaps the antenna off on the window as he pulls it out. In the next shot, it is on again.
Corrected entry: When Val and Earl are pumping out a septic tank, the hose springs a leak and sewage jets out all over them. In real life, these hoses suck (negative pressure, like a vacuum cleaner), so if the hose had a hole, it would just suck air through the hole, not shoot out liquid.
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: Val runs to save Mindy who is jumping on her pogo stick. When he snatches her off of it, the pogostick stays standing completly upright. The camera cuts to Val, Mindy and Mindy's mom. They have a bit of dialogue. It cuts back to the pogostick that's standing straight up, and the graboid sucks it into the ground. It would have had to have been standing for around 5 seconds before the graboid got to it, on its end and unsupported.
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 snakeoids 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.Krista
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 we first see Val and Earl in Chang's market, Val tells a joke about surviving World War 3 to Burt; you can obviously tell that Earl starts laughing before Val gets to the punch line. He quickly takes a huge swig of beer to cover it up.
Corrected entry: When Earl and Val stop to warn the sandblasters that there is a 'psycho killer' on the loose, Earl is talking frantically but if you look at Val, he doesn't look at all phased - surprising considering he just found half a chewed human head and a herd of chewed sheep.
Corrected entry: After Earl, Val, and Rhonda pole vault to the last rock, there's a shot of Earl's feet landing on the rock. But when the camera pulls back, he is holding his pole facing forwards. If he had just pole-vaulted to the rock, the pole would be behind him, and he probably wouldn't have landed so smoothly either.
Corrected entry: When the doctor's wife is in the station wagon, there's a coffee cup on the dash at first. In later shots it disappears.
Corrected entry: When Val & Earl are leaving Perfection, they have everything they own in the pickup truck. When they get Edgar down from the tower and take him to the doctor's home, there is nothing in the truck. Scenes later when the "grab-oid" is attacking Val & Earl's truck in town it is full again.
Corrected entry: In the start of the movie Earl, and Burt can't leave Perfection because the road is "blocked" the rocks falling. Why didn't they just drive around the rocks on the shoulder? Or if they really wanted to leave just take down a barbed wire fence, drive over it, and put it back up? These guys were experienced cowboys yet a little pile of rocks stopped them dead in their tracks.
Corrected entry: When Val gets the cat to go to the mountains, he pulls a trailer semi. When he is tying the chain to connect the cat to the semi, there's dirt in the semi. Later when everyone is in, the dirt is gone.
