First Reactions to ‘The Cat in the Hat’ Call Warner Bros.’ Animated Debut Funny, Heartfelt and a Little Demented

Few children’s books have had as bumpy a trip to the big screen as Dr. Seuss’s 1957 classic. The last major attempt, a 2003 live-action version starring Mike Myers, was widely panned and sits at a 10% approval rating on Rotten Tomatoes. It also led the Seuss estate to steer future feature films toward animation.

Warner Bros. Pictures Animation is now giving the mischievous feline another shot. ‘The Cat in the Hat’ is the relaunched studio’s first full-length feature, built on a multi-picture pact with Dr. Seuss Enterprises, and it has already changed dates more than once.

With the movie only days from theaters, the first wave of reactions has arrived, and the early word is encouraging. Initial viewers describe ‘The Cat in the Hat’ as wildly funny and wonderful, inventive and heartfelt, whimsical, and often very funny.

One of the most intriguing early takes compares the film to a wilder, modern-day Mary Poppins. It’s a fitting comparison given the setup, in which the Cat appears in the lives of two kids who need cheering up and drags them into a series of fantastical adventures.

The film’s Cat is a chaotic fixer rather than a gentle nanny. Bill Hader voices the character, with the studio describing him as spreading joy to kids in a hilarious, signature and singularly irreverent way.

Early reactions also highlight the film’s tone. Words like whimsical and heartfelt suggest the filmmakers found a balance between mayhem and emotion, something the 2003 version famously failed to do.

The story follows a Cat who now works for the Institute for the Institution of Imagination and Inspiration, LLC, known as the I.I.I.I. His toughest assignment yet is to cheer up Gabby and Sebastian, a pair of siblings struggling with a move to a new town.

Known for taking things too far, the Cat could be facing his last chance to prove himself, or lose his magical hat. The trailer introduced familiar faces like Pig With a Wig, Yack With a Pack and the popular Things 1 and 2, along with several more.

Through the contents of their unpacked boxes and with help from the Cat, who transforms their couch into a vehicle, the children are taken on a series of adventures. It’s a clever way to build a new story around the old one.

Alongside Hader, Xochitl Gomez voices Gabby, with Tiago Martinez as Sebastian. Matt Berry plays the Fish, Quinta Brunson plays Sherri, Giancarlo Esposito voices the Cat’s exasperated boss, and America Ferrera plays the children’s mother.

Paula Pell, Bowen Yang and Tituss Burgess round out the cast. Behind the camera, Alessandro Carloni (known for ‘Kung Fu Panda 3’) and Erica Rivinoja co-wrote and co-directed, with Daniela Mazzucato and Jared Stern producing. Hader also serves as an executive producer, and DNEG Animation handled the animation, with music by Lorne Balfe.

Hader has a history with the role. He played the Cat during his 2014 hosting gig on ‘Saturday Night Live’, joining a lineage of ‘SNL’ alumni who have played the character, including Myers and Martin Short.

The path to release hasn’t been simple. The film was originally dated for early 2026, then set for February 27, before Warner Bros. moved it to November 6, 2026.

The studio said the later date offers a long runway for extended playability and reinforces its belief that the film is an event for generations of moviegoers. It also takes advantage of the holiday season and merchandising opportunities.

The stylistic approach matters too. The film uses stylized computer animation to explore the exaggerated shapes, bold colors and surreal transformations of Seuss’s illustrations, moving away from the 2003 live-action look.

For now, these are early reactions rather than formal critics’ reviews, and Rotten Tomatoes had not yet posted a Tomatometer score in the listings I found. The picture will become clearer once the review embargo lifts and audiences weigh in.
