Most Disgusting Horror Movies

Olaf Ittenbach's Premutos: Lord Of The Living Dead isn't as famous as some of the other movies on this list, but it occupies a precious spot in the bloody hearts of gore fans. The German director positively revels in spilling blood left and right, and this thriller takes things to a point of absolute insanity. In the movie's blood-soaked climax, zombies are being dispatched left and right, with gallons of red flying and body parts getting chopped off like crazy. Head explosions come fast and furious, and the scenes of the undead eating the living are tough to watch. It's hard to say if the awful English dubbing ruins the experience or improves it.

The first Human Centipede movie was stomach-turning, no doubt. But director Tom Six ensured that it wouldn't get a spot on this list simply by making the sequel. When a schlubby British parking lot attendant becomes obsessed with the first film and decides to duplicate its experiment, he goes all the way—connecting twelve people together into one hideous beast. The first film at least had a doctor doing the dirty deed—the sequel's protagonist uses a staple gun to make his monster, and the whole movie is drowning in blood, feces, and other disgustingness. People have been passing out at screenings.

Brian Yuzna's grotesque Society doesn't get its power from gore—there's barely a drop of blood spilled in it compared to some of the other flicks on this list. And yet, it's still incredibly grotesque, perverse and terrifying. The movie is about a group of rich, popular people in Beverly Hills who are actually disgusting amorphous creatures who feed on the bodily fluids of human beings. How they feed is where things get gross—in a process called "shunting," they lose all control of their bodies and melt into a sloppy, orgiastic mass of flesh. The movie's epic climax where this happens is hard to watch without flinching.

Back to the world of the zombies with the very gruesome Bone Sickness. The story is simple: a young man is afflicted with a bizarre, unexplained disorder that is causing his bones to decay. Without health insurance, he's forced to turn to a mortician's assistant who is devising peculiar home remedies from corpses. Yeah, that sounds sanitary. Before you know it, those defiled corpses are rising from the grave to get a little payback, and things only get grosser from there.
