‘The Simpsons’ Casting Director Scott Muller to Recruit Voices for Animated Film ‘The Most Serious Fart’

“The Simpsons” casting director Scott Muller will oversee voice casting for “The Most Serious Fart,” Utopai‘s animated feature based on Mike Bender’s bestselling children’s book, which wafts into theaters in 2027.

“The Most Serious Fart” follows Siegfried, an uptight fart who is ashamed of who he is and determined to change farts into something respectable. Siegfried sets out on a journey that ultimately teaches him to accept himself, find friendship and discover fun along the way.

“Voice casting will define how audiences first connect with Siegfried and the world around him,” Muller said in a statement. “Mike has created characters that invite bold comedy but also have a genuine emotional point of view. I am excited to find the voices that can make the humor land while giving the story the warmth and humanity at its center.”

Muller has also worked as the casting director on “Futurama,” “King of the Hill” and the animated “Napoleon Dynamite” series. He is joined by “Coyote vs. Acme” story artist Andy Brooks as key story artist, Bender as writer, director and producer. Russell Hollander will also produce.

Human animators and illustrators will lead the creative process and originate the film’s artwork. AI will be used selectively as a production tool to support iteration under their direction, Utopai said in a statement.

“From the beginning, our goal has been to make a film that feels as distinctive as the book,” Bender said. “Scott understands how much performance shapes an animated world. Andy brings a remarkable ability to tell stories through character, expression and movement. Together with the rest of our creative team, they will help make Siegfried’s world feel completely original while keeping its heart intact.”
