The Cat in the Hat main trailer

The Cat in the Hat is an animated adventure about the Cat’s mission to cheer Gabby and Sebastian, siblings struggling after moving to a new town. Voiced by Bill Hader, it opens in Korea on November 4,

A cat in a hat appears before siblings Gabby and Sebastian, who are struggling to adjust after moving to a new town. The main trailer presents cheering the two children up again as the cat’s mission, linking the familiar mischievous character to the siblings’ transformation.

The cat, a member of I.I.I.I. (Institute for the Institution of Imagination and Inspiration, LLC), is assigned his most difficult mission yet. Dispatched from the world of imagination and inspiration, he leads the children into unfamiliar worlds, but because of his tendency to cross every line, he could lose even his magic hat if he fails this mission.

The film is the first feature-length Warner Bros. Pictures animated film based on a book by Dr. Seuss. Bill Hader voices the cat, with Matt Berry, Quinta Brunson, Xochitl Gomez, Giancarlo Esposito, and America Ferrera also starring. Erica Rivinoja and Alessandro Carloni co-directed the film.

In North America, it will be released in theaters and IMAX on November 6, 2026, while its Korean release is scheduled for November 4, two days earlier. Warner Bros. Pictures is handling worldwide distribution.
