The Star-Studded Voice Cast of ‘The Cat in the Hat’ (with Pictures)

Warner Bros. Pictures Animation brings Dr. Seuss’s iconic story back to the big screen with the animated feature film ‘The Cat in the Hat’ (2026). Directed by Alessandro Carloni and Erica Rivinoja, this cinematic adaptation reimagines the classic literary character as a professional agent operating under the Institute for the Institution of Imagination and Inspiration, LLC.

When assigned to assist two siblings facing a difficult adjustment to a new hometown, the whimsical feline embarks on an imaginative and chaotic mission to restore their spirits. An ensemble cast consisting of acclaimed comedic performers and dramatic actors lends their vocal talents to bring these reimagined and newly created characters to life.

The role expands upon Hader’s extensive voice-acting career in animated features such as ‘Inside Out’ and ‘Cloudy with a Chance of Meatballs’.
