John Ratzenberger
An American character actor and voice artist affectionately known as Pixar's good-luck charm, having voiced a role in every one of the studio's feature films. He first won fame as the know-it-all mailman Cliff Clavin on the sitcom 'Cheers', then lent his gravelly warmth to Hamm the piggy bank in 'Toy Story' (1995) and its sequels, John the assembly-line worker in 'WALL·E' (2008), and parts in 'Up' (2009), 'Monsters, Inc.' (2001) and 'Ratatouille' (2007). A familiar, reassuring presence, he remains one of animation's most heard voices.
