In the realm of things that go bump in the night ... another animated flick from Pixar (Toy Story, Toy Story 2, A Bug`s Life), this comedy-adventure tells the story of a large, furry, spotted, and horned James P. Sullivan (John Goodman) and his best friend and roommate, a green, opinionated, feisty little one-eyed monster (Billy Crystal), who audition for spots under children`s beds. They then must capture the children`s screams, that provide the energy on which the monsters live. When the two accidently transport a little girl (Mary Gibbs) back to their realm — an absolute no-no — they are exiled from their land by the factory`s mean crablike CEO (James Coburn) and are forced to live in the human world.
