Warner Bros. Pictures Animation’s first full-length feature film, The Cat in the Hat, comes to theaters and IMAX across North America on November 6, 2026, and internationally beginning 4 November 2026.

The Cat in the Hat is directed by Erica Rivinoja and Alessandro Carloni from their own screenplay, story by Caroline Williams, and produced by Daniela Mazzucato. 

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.  Here’s the trailer which just dropped today:
