Doing what he does best, the Cat—voiced by Bill Hader—spreads joy to kids in his hilarious, signature and singularly irreverent way, transporting them and audiences on a fantastical journey through a world they’ve never seen before.

In the film, our hero takes on his toughest assignment yet for the I.I.I.I. (Institute for the Institution of Imagination and Inspiration, LLC): to cheer Gabby and Sebastian, a pair of siblings struggling with their move to a new town. Known for taking things too far, this could be this agent of chaos’s last chance to prove himself…or lose his magical hat!

Starring alongside Hader are Xochitl Gomez, Matt Berry, Quinta Brunson, and Paula Pell, and featuring Tiago Martinez, Giancarlo Esposito, America Ferrera, Bowen Yang, and Tituss Burgess.

Directed by Alessandro Carloni and Erica Rivinoja, Warner Bros. Pictures Animation’s first full-length feature film, The Cat in the Hat, comes to Australian cinemas in 2026. It will be distributed worldwide by Warner Bros. Pictures.
