Bill Hader to Star in Warner Bros. Pictures Animation’s ‘The Cat in the Hat’

Warner Bros. Pictures Animation and Dr. Seuss Enterprises have announced an all-star comedic cast for the upcoming feature film, “The Cat in the Hat,” which will debut in theaters globally on March 6, 2026. The cast, led by Bill Hader (Barry) as The Cat, includes Quinta Brunson (Abbott Elementary), Bowen Yang (SNL), Xochitl Gomez (Doctor Strange in the Multiverse of Madness), Matt Berry (What We Do in The Shadows) and Paula Pell (Girls5eva).

In the whimsical tradition of Dr. Seuss, “The Cat in the Hat” comes to the big screen in his animated theatrical feature film debut, doing what he does best – spreading joy to “happyless” kids. In the film, The Cat takes on his toughest assignment yet: to cheer a pair of siblings struggling with their move to a new town.

“We are overjoyed to partner with our friends at Dr. Seuss to take audiences of all ages on an adventure into the beloved world of ‘The Cat in the Hat,’” says Bill Damaschke, president, Warner Bros. Pictures Animation. “With this incredible voice cast led by Bill Hader as the fun-loving, agent of chaos himself, and our filmmakers, Alessandro and Erica at the helm, we look forward to sharing this Seussian cinematic spectacle with audiences everywhere in 2026.”

“We are excited to see such an exceptional group of talent join the effort to bring this iconic property to the screen as an animated feature,” says Susan Brandt, president, chief executive officer, Dr. Seuss Enterprises. “It’s been an amazing experience collaborating with the team from Warner Bros. Pictures Animation so far, as they truly understand what it takes to capture the magic of ‘The Cat in the Hat’ and share his brand of imagination and joy with a new generation of Dr. Seuss fans.”
