The first audiences to see The Cat in the Hat have spoken, and the early word is about as encouraging as Warner Bros. could have hoped. Ahead of the animated film’s November 6, 2026 theatrical release, first reactions from its world premiere describe Bill Hader’s take on Dr. Seuss’s mischievous feline as wonderful, inventive, heartfelt and very funny — with several early viewers calling it the best Seuss film ever put on screen.
That is a bold claim for a character whose last big-screen outing, the 2003 live-action film starring Mike Myers, was widely panned and sits at around 10% on Rotten Tomatoes. But the new film is a different animal entirely: a fully animated feature, the first from the relaunched Warner Bros. Pictures Animation, with a stacked voice cast and a story that gives the Cat something he never had before — a job to lose.

What the first reactions actually say
The reactions arrived after the film’s world premiere at Warner Bros. Studios Burbank, to a consistent tone of surprise at how well it works.
Writer Drew Taylor called the film “really wonderful — fun, inventive, heartfelt, whimsical and often very funny, with great animation.” The Nerds of Color went further, describing it as “a lovely surprise” and “the best Seuss film to be put on screen,” praising Hader’s performance and the film’s imagination. Another early viewer, Disway80, wrote that the story is “not just about the laughs and the fun, it’s a story about growing and understanding our parents,” and singled out animation that is “absolutely gorgeous.”
A very different Cat
Rather than simply turning up on a rainy day, this Cat works for the I.I.I.I. — the Institute for the Institution of Imagination and Inspiration, LLC — and takes on his toughest assignment yet to prove himself to his frustrated boss and save his job. His charges are Gabby and Sebastian, a brother and sister struggling with their family’s move to a new town.
Hader, who also serves as an executive producer, is a fitting choice: he played the Cat during his 2014 hosting stint on Saturday Night Live. Matt Berry voices the Fish, with Xochitl Gomez, Quinta Brunson, Giancarlo Esposito, America Ferrera, Bowen Yang and Tituss Burgess in the ensemble.
The long road to November 6
The path to release has not been simple. The film was originally dated for early 2026, then set for February 27, before Warner Bros. moved it to November 6, 2026, citing a long runway for extended playability.
The stakes are real. This is Warner Bros. Pictures Animation’s first full-length feature, built on a multi-picture pact with Dr. Seuss Enterprises, and early tracking reported by Koimoi puts its North American opening weekend at around $40 million.
The 2003 shadow
None of this guarantees success, and the film still has one ghost to outrun. The 2003 live-action Cat in the Hat remains a cautionary tale — a film so poorly received that it effectively ended live-action Seuss adaptations. The new film’s answer is to go back to animation, where Seuss’s world always belonged, and to trust Hader’s comic timing rather than prosthetics and slapstick.
Early reactions, it should be stressed, are not reviews. They come from premiere audiences, they skew positive by nature, and Rotten Tomatoes had not posted a Tomatometer score at the time of writing. The full critical verdict arrives only when the review embargo lifts in release week.
What to watch for next
Three things will decide whether the early buzz holds: the Tomatometer score once formal reviews land, whether that reported $40 million opening tracking firms up, and whether audiences embrace a Cat who is less nanny and more agent of chaos. On the evidence of the first reactions, the film has given itself the best possible start. Audiences find out for themselves on November 6.
