Munchies (film)
Munchies is a 1987 comedy horror film starring Harvey Korman, Charlie Stratton, and Nadine Van der Velde. Clearly inspired by the success of Gremlins, and directed by that films editor, Tina Hirsch, the film features a remarkably similar plot line. It spawned two sequels, Munchie and Munchie Strikes Back, which possess no relation to the original save the title. These two films dealt with an impish wishgranting creature named Munchie.
When Arnold is hurt by his kidnappers, it becomes aggressive and attacks Cecils adopted son. Attempting to kill Arnold, they chop him into quarters, but instead of dying, Arnold multiplies into four new munchies. The quartet of creatures develop a love of women, beer, attacking people, and junk food in the process.
