"Fixed" brings together a number of comedy heavy-hitters for its voice cast, led by Adam Devine as Bull. Insofar as a human actor could be appropriately cast as a soon-to-be neutered dog, Devine — with his background in ridiculous comedies like "Workaholics" and "The Righteous Gemstones" — comes pretty damn close. Idris Elba co-stars as his best friend, Rocco. Genndy Tartakovsky assured Variety that Elba's fame, honed in projects like "The Wire" and "Luther," wouldn't distract from the role. "When Idris is doing Rocco, you may recognize him, but then you just settle in."
Kathryn Hahn, who previously collaborated with Tartakovsky on "Hotel Transylvania," stars as Bull's love interest, Honey. Hahn, who cut her teeth in comedies like "Anchorman" and "Step Brothers," was adamant that her character has some edge. Producer Michelle Murdocca recalled, "When Kathryn decided to do it, she told us: 'I want to be just like the guys. I don't want to be the sweet girl in the background who doesn't have any depth to her. Make her a little raunchier.' Hiring her made this character come alive."
The rest of the "Fixed" cast includes Fred Armisen, Michelle Buteau, Beck Bennett, Bobby Moynihan, and River Gallo.
