In Pixar's Cars, who provides the voice of rusty tow truck Mater?

In Pixar's Cars, rusty tow truck Mater is voiced by Larry the Cable Guy.

Larry the Cable Guy is the stage name of comedian Daniel Lawrence Whitney. His exaggerated rural-comedy persona and distinctive delivery became central to Mater's personality: friendly, excitable, loyal, and often unintentionally funny. Mater's speech patterns and enthusiasm provide much of the film's comic energy.

Mater is a tow truck who lives in Radiator Springs and quickly becomes Lightning McQueen's closest friend. Although he appears unsophisticated, he is observant, generous, and brave. The character's name is a shortened form of “tomater,” matching the film's playful vehicle-based wordplay.

A frequent casting mistake is crediting John Ratzenberger, who voices Mack, Lightning McQueen's transport truck. George Carlin voices Fillmore, the town's Volkswagen Type 2-style hippie van, while Cheech Marin voices Ramone. Larry the Cable Guy continued as Mater in later Cars films and related Pixar productions.
