Monsters, Inc. is a 2001 American computer-animated comedy film directed by Pete Docter, produced by Pixar Animation Studios and released by Walt Disney Pictures. Co-directed by Lee Unkrich and David Silverman, the film centers around two monsters employed at the titular Monsters, Inc.: top scarer James P. "Sulley" Sullivan (John Goodman), and his one-eyed assistant and best friend, Mike Wazowski (Billy Crystal). Monsters, Inc. employees generate their city's power by targeting and scaring children, but they are themselves afraid that the children may contaminate them; when one child enters Monstropolis, Mike and Sulley must return her.
