Warner Bros. Pictures Animation has unveiled the first trailer for its first full-length feature, The Cat in the Hat, an animated adaptation of the classic Dr. Seuss story starring Bill Hader.
In the film, 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. Our hero’s toughest assignment yet comes from the I.I.I.I. (Institute for the Institution of Imagination and Inspiration, LLC), which asks him to cheer up 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’ last chance to prove himself…or lose his magical hat!
Directed by Alessandro Carloni and Erica Rivinoja, the film will hit theaters and IMAX across North America on February 27, 2026, and internationally beginning February 25. Starring alongside Hader are Xochitl Gomez, Matt Berry, Quinta Brunson, Paula Pell, Tiago Martinez, Giancarlo Esposito, America Ferrera, Bowen Yang, and Tituss Burgess.
Enduringly popular since its publication in 1957, The Cat in the Hat was previously most famously adapted as a 2003 live-action film directed by Bo Welch and starring Mike Myers. Adapted prior to that into a 1971 animated television special for CBS, produced by Chuck Jones, who had worked on many of the Looney Tunes cartoons, the book’s central character has also made appearances over the years in projects like the ’90s puppet series The Wubbulous World of Dr. Seuss and the educational kids’ series The Cat in the Hat Knows a Lot About That!.
