Hick handymen Val McKee and Earl Bassett can barely eke out a living in the Nevada hamlet of Perfection, so they decide to leave town -- despite an admonition from a shapely seismology coed who's picking up odd readings on her equipment. Before long, Val and Earl discover what's responsible for those readings: 30-foot-long carnivorous worms with a proclivity for sucking their prey underground.
This movie contains 24 potentially triggering events.
“Meat parts purchased from a butcher were used to simulate the mutilated sheep. To simulate a monster attacking the horse, fake tentacles were wrapped around the horse. The movement of the tentacles was achieved by an inner mechanism which was operated manually. The horse was not at all frightened by this. The horse then laid down, which he was trained to do. Collapsible stirrups were used to protect the horse. A veterinarian sedated the horse briefly and an AHA representative was present at all times. A prop of fake horse flank was used where the monster bites into the horse.”
Domestic sheep and horses are killed by the graboids. I unfortunately can’t provide time stamps at the moment, but the sheep are found dead but killed off screen near the beginning of the movie, and the horses are killed on screen towards the middle whilst Val and Earl try to ride away from the graboids.
Horses, sheep, and the main monsters (graboids) all die during the film. The horses and graboids are actively killed on screen, the sheep are only shown dead.
EDIT: I now realize that this probably meant characters who are a fantasy race other than human but are still anthropomorphic, but I’ll keep it here still, just in case.
Not entirely graphic but worth mentioning just in case. Near the very end of the movie whilst they’re trapped on a rock by the graboids, Burt talks about lighting up one of the pipe bombs he made and walking out into the desert, letting one of the gaboids take him down.
Not sure what the other yes vote is referring to specifically, but some of the sound effects are rough. The screeching of the monsters when injured is probably the worst.
