Overview
- Warner Bros released the third trailer on Thursday, Sept. 10, 2026, confirming Bill Hader as the voice of the Cat and repeating the studio's November 6, 2026 theatrical and IMAX release date.
- The trailer and studio materials name Xochitl Gomez, Matt Berry, Quinta Brunson, Paula Pell, Tiago Martinez, Giancarlo Esposito, America Ferrera, Bowen Yang, and Tituss Burgess among the principal voice cast.
- Erica Rivinoja and Alessandro Carloni are credited as co-directors and co-writers from a story by Caroline Williams with Daniela Mazzucato producing, signaling a team with recent family-animation experience.
- Warner Bros frames the story as a heart-centered adventure: the Cat is dispatched by the fictional I.I.I.I. to cheer siblings Gabby and Sebastian as they cope with moving to a new town, and outlets note the trailer leans into emotional, family-friendly beats.
- The film joins a long line of Dr. Seuss screen adaptations and follows the 2003 live-action Cat in the Hat; the new animated take expands the short book into a larger, emotionally driven feature and could shape fall family-box-office competition.
