Comedian Don Rickles had already committed to the fourth Toy Story film when he passed away in 2017. Though none of his scenes had been recorded, the family requested that Pixar somehow include his voice in the last movie. Director Josh Cooley confirmed the inclusion of Rickles in Toy Story 4 and said the Pixar team used archived recordings from the first three films to piece together Mr. Potato Head’s role in the franchise’s final chapter. “And so I’m very honored that they asked us to do that, and I’m very honored that he’s in the film,” Cooley said. “Nobody can replace him.”
When Rickles passed away, costars expressed their mourning of a comedic great. Tim Allen called Rickles one of his inspirations, saying, “I feel bad, mostly for everyone in heaven who will now learn firsthand from the sharpest wits ever, what it’s like to be Rickled.”
