Which actor voices Mike Wazowski in the original English version of Monsters, Inc.?

Billy Crystal voices Mike Wazowski in the original English version of Monsters, Inc.

Mike Wazowski is the small, green, one-eyed monster who works as Sulley’s assistant and closest friend. Crystal’s energetic comic delivery helps define Mike as fast-talking, ambitious, anxious, and frequently overwhelmed by the consequences of his own plans.

John Goodman voices James P. Sullivan, so the two actors form the film’s central voice partnership. Steve Buscemi voices Randall Boggs, the rival scarer, while John Ratzenberger voices Yeti. Keeping these roles separate is useful because all four characters are prominent members of the factory’s story.

Crystal reprised the role in the prequel Monsters University, which was released in 2013. Mike’s character is also central to the later television series Monsters at Work, extending the role beyond the original feature film.
