First Look: Animated Cat in the Hat Trailer Brings Seuss Classic to Life!

Today is going to be THE. BEST. DAY. EVER!
Bill Hader stars as The Cat in the Hat — only in cinemas February 2026.

Meet the Cat in the Hat like you’ve never seen him before. In the wonderfully whimsical tradition of Dr. Seuss, The Cat in the Hat leaps onto the big screen in his animated theatrical feature debut — an all-new, epic adventure where mischief, magic, and mayhem rule.

Doing what he does best, the Cat — voiced by Bill Hader — brings joy to kids in his hilarious, irreverent way, whisking them and audiences away on a fantastical journey through a world of wild imagination.

In this story, our striped-hatted hero faces his greatest challenge yet. On a mission for the Institute for the Institution of Imagination and Inspiration (I.I.I.I.), he’s tasked with cheering up Gabby and Sebastian, two siblings struggling to adjust after moving to a new town. Known for taking things a little too far, this may be his last chance to prove himself… or risk losing his magical hat for good.

The film also stars Xochitl Gomez, Matt Berry, Quinta Brunson, and Paula Pell, with performances by Tiago Martinez, Giancarlo Esposito, America Ferrera, Bowen Yang, and Tituss Burgess.

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