Tremors (1990) - 38 mistakes

Revealing: When the lawn mower the heroes send off as a diversion crashes you can see a wire pulling it.

Continuity: When Val and Earl are being chased by the graboid in the first shot it appears that the graboid is going perpendicular to the fence (you can see this because of the wires that cross it). But in the next shot the graboid appears to be going parallel to the fence.

Continuity: When they all are trying to lure the graboids away from Val, Rhonda looks down the pipe running down the from the water tank. A piece of cloth soaked in water is tied around the pipe and water is dripping from it. When it cuts to Rhonda climbing down the water has stopped dripping.

Continuity: When they are picking up Burt and Heather, Burt throws a sack to Val. When it cuts Val catches a totally different sack.

Visible crew/equipment: When Bert kills one of the monsters in his place, the shot goes to Val and Earl they congratulate Bert over the radio. When the shot goes back to Bert, pause the dvd or go to slow motion, and look at the window as it pans up, you can see a man with a red cap just standing there.

Continuity: 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.

Revealing: Near the end, Val, Earl and Rhonda are way off the rocks after the blast. When the monster comes up out of the ground and Earl takes off, you can see the "ground" bounce. It's definitely a false ground so they can get the "snake-oid" pushed up through it.

Revealing: When the horse is lying on the ground with the tentacle wrapped around it, you can see a wire to the left of the screen attached to the horse.

Factual error: Throughout the entire film Burt holds all of his rifles' butts underneath his armpit, rather than against his shoulder. A trained "survivalist" such as him would surely know better. Holding the "elephant gun" in such a way would most likely break his arm, wrist and hand when it fired.

Continuity: When we see Rhonda placing a sensor to the ground we see her throwing her cap to the ground. When it cuts the cap has moved closer to the hole in the ground.

Continuity: When Dr. Jim and his wife are backing away from where the generator was, you can see them moving towards the car behind them. When it cuts, they are now facing the car.

Continuity: When Valentine and Earl gets to Chan's, you see Heather packing some stuff into a box. She then takes a ketchup bottle in her left hand and a spray box in her right hand. When it cuts she is holding the ketchup in her right hand.

Continuity: When the snakeoid is chasing Val and Earl after they lose their horses, they run along a fence and the monster causes all the fence posts to fall over backwards. But shortly after, all the fence posts are seen to be upright, although some are tilted a little to the right.

Continuity: When Rhonda, Earl and Val are pole vaulting from rock to rock, if you look closely you can see that the poles are a lot longer than when they first picked them up off the ground.

Revealing: As the last Graboid falls off the cliff at the end, just before it hits the ground, you can see its skin has already been cut up for the "blood" to gush out of upon impact.

Continuity: In the movie, Earl's last name was Basset, but in the credits, his last name was Bass.

Visible crew/equipment: Look over Val's right shoulder as Rhonda is supposedly driving upside down with her legs sticking out the back window of the truck cab and you can se a man driving for her.

Continuity: In the beginning of the movie, watch Kevin Bacon's hair when they're driving in the truck. In some camera shots, his hair is blowing in the wind. In others, his hair is not moving at all. This happens several times.

Continuity: At Dr. Jim's when he is standing by where the generator should be, you can see several items around. When it cuts all the items has moved.

Audio problem: Right after Bert kills the second graboid he gets on the radio and says "we killed that mother-humper". Val replies "...be advised there are two more mother-humpers". However Val's lips don't seem to be saying "humper". This occurs even in unedited versions of the film.
