Monsters, Inc. - Voice Cast

Voice Cast

• John Goodman as James P. "Sulley" Sullivan – Sulley is a giant furry blue friendly and sweet monster with horns and purple spots. Even though he excels at scaring children, he is kind hearted and thoughtful by nature. Sulley is relatively laid-back, and has a relaxed, outgoing and happy personality. In the beginning of the film he is "The Best Scarer" for several months running.
• Billy Crystal as Michael "Mike" Wazowski – Mike is a green monster with a ball-shaped body, a single big eyeball, and skinny arms and legs. He runs Sulley's station on the scare floor, and they are close friends and roommates. Mike has an outgoing personality and is dating Celia Mae. He has an ego that often makes him forget something obvious, such as how his face is obscured in advertisements for the company. He makes cameo appearances in Finding Nemo, Cars, WALL-E and Toy Story 3.
• Mary Gibbs as Boo – A 2-year-old human girl who is unafraid of any monster except Randall, who regularly scares her at night. She refers to Sulley as "Kitty". The book based on the film gives Boo's "real" name as Mary Gibbs, the name of her voice actress. In the film, one of Boo's drawings is covered with the name "Mary."
• Steve Buscemi as Randall Boggs – An impatient, multi-legged lizard-shaped monster with a chameleon-like ability to change skin color and blend in completely with his surroundings. He is Mike and Sulley's rival in scream collection.
• Jennifer Tilly as Celia Mae – A gorgon-like monster with one eye, snakes for hair, and tentacle-like legs. She is Mike's girlfriend and the receptionist for Monsters, Inc.
• James Coburn as Henry J. Waternoose III – A spider or crab-like monster with five eyes. At the start of the film, he is CEO of Monsters, Inc., the job having been in his family for three generations. He somewhat holds a mentor-like relationship with Sulley, believing him to be the best scarer.
• Bob Peterson as Roz – A slug-like monster with a raspy voice, similar to Selma Diamond's. She is the administrative clerk for Scarefloor F and "number 1" in the CDA, who has been doing secret work around Monsters, Inc. for about 2 years.
• Frank Oz as Jeff Fungus – Randall's red-skinned three-eyed assistant and reluctant participant in the plot.
• John Ratzenberger as The Abominable Snowman – A yeti banished to the Himalayas. He is also a relative of Bigfoot who like him and the Loch Ness Monster were also banished.
• Sam Black as George Sanderson – A furry monster with a horn on top of his head, he was frequently assisted by Charlie. He is the butt of a running gag in which he repeatedly contacts human artifacts by accident (due to the static cling of his fur), triggering "23–19" incidents and humorously overblown reactions by the CDA resulting in the removal of his hair.
• Phil Proctor as Charlie - George's assistant with blue skin,two octopus like arms, four tantacles as feet and snail like eyes.He is very friendly and admires Sulley and Mike's work.
• Dan Gerson as Smitty and Needleman – Two goofy monsters with cracking voices who work as janitors and operate the Door Shredder when required. They (almost excessively) idolize Sulley.
• Bonnie Hunt as Ms. Flint – A snake-like monster who trains new monsters to scare children.
• Jeff Pidgeon as Thaddeus "Phlegm" Bile – A trainee scarer for Monsters, Inc.
