Jeff Lieberman’s cult horror classic Squirm proves that the saying “A little dirt never hurt anyone” could not be more wrong. A violent storm in Fly Creek causes power lines to fall, sending electrical currents into the ground and bringing up evil worms seeking vengeance. At first, residents of the tiny town are hesitant to believe city boy Mick when he finds a worm in his egg cream, until the creepy-crawlies turn up everywhere, including in lead character Geri’s showerhead (a sick twist on Psycho‘s famous shower scene) and writhing down walls. In a pivotal nature-strikes-back scene, a man overturns a bucket full of bait worms while in a boat, and the earthworms proceed to bite and bore holes into his face. That’ll learn him.
