Monsters, Inc. (also known as Monsters, Incorporated) is a 2001 American animated comedy film produced by Pixar Animation Studios for Walt Disney Pictures, and starring the voices of John Goodman, Billy Crystal, Steve Buscemi, James Coburn, Jennifer Tilly, and Mary Gibbs. Directed by Pete Docter, and written by Andrew Stanton and Daniel Gerson, the film centers on two monsters, the hairy James P. "Sulley" Sullivan (Goodman) and his one-eyed partner and best friend Mike Wazowski (Crystal), who are employed at the titular energy-producing factory Monsters, Inc., which generates power by scaring human children. However, the monster world believes that the children are toxic, and when a little human girl, Boo (Gibbs), sneaks into the factory, the duo must safely return her home while evading discovery.

Plot

In a world inhabited by monsters, the city of Monstropolis harnesses the screams of human children for energy. At the Monsters Incorporated factory, skilled monsters employed as "scarers" enter the human world to scare children and harvest their screams through electronic portals connected to the closet doors of children's bedrooms. The work is considered dangerous, as human children are rumored to be toxic enough to kill a monster through physical contact. Monsters, Inc. CEO, Henry J. Waternoose III, is concerned about the declining energy production, as children are becoming less easily scared.
