Monsters, Inc.

Every night, the professional scarers of Monsters, Inc., sneak into children's bedroom closets around the world, eliciting screams that they convert into the energy their world needs. Aside from a minor power shortage, life is just fine for top scarer James P. "Sulley" Sullivan (John Goodman) and his assistant, Mike (Billy Crystal) -- until a little girl named Boo accidentally finds her way into the monster world -- and into Sulley's heart.
