This Hamm casting was inspired by the Radiator Springs Drive-In scene in Cars, in which Toy Story was playing, the characters switched to wheeled versions of themselves, and actor John Ratzenberger reprising his role voicing Hamm. Ratzenberger also voiced Mack in Cars, complimenting his own work at the drive-in. Funny stuff! Check out the video:
