The Cat in the Hat

Synopsis

Meet the Cat in the Hat you don’t know! In the wonderfully whimsical tradition of Dr. Seuss, The Cat in the Hat comes to the big screen in his animated theatrical feature film debut, an all-new, epic adventure with an edge, where mischief, magic and mayhem reign supreme. 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 Matt Berry, Quinta Brunson, Xochitl Gomez, with Giancarlo Esposito, and America Ferrera. Tituss Burgess, Bowen Yang, Paula Pell and Tiago Martinez also star.

The Cat in the Hat is directed by Erica Rivinoja and Alessandro Carloni from their own screenplay, screen story by Caroline Williams, based on the book by Dr. Seuss. It is produced by Daniela Mazzucato and Jared Stern. The executive producers are Bill Hader, Susan Brandt, Bill Damaschke, Kelly Marcel and Steve Zissis, Tim Story and Alex Timbers. It is edited by Dan Molina, with music by Lorne Balfe. 

Directed by Alessandro Carloni and Erica Rivinoja, Warner Bros. Pictures Animation’s first full-length feature film, The Cat in the Hat, comes to cinemas and IMAX in the UK and Ireland on December 4, 2026.  It will be distributed worldwide by Warner Bros. Pictures.
