Bill Hader Shocks Fans With Unannounced Return Project—Inside the Comedian’s Next Big Move

Bill Hader has slipped into one very mischievous set of whiskers: Warner Bros. Animation dropped the first trailer for its 2026 feature “The Cat in the Hat,” revealing the Emmy-winning “Barry” creator voicing Dr. Seuss’s iconic feline trouble-maker. The two-minute teaser opens on a windswept suburban street before Hader’s Cat appears with his signature red-and-white stovepipe hat, promising “an adventure that’s out of the box—literally.” Within seconds, Thing 1 and Thing 2 are shredding the Fish’s calm, Sally and her brother are rocketing through the house on a pink hover-vac, and an exasperated neighbor is pelted with green goop. Search-friendly storyline details • Plot setup: Stuck inside on a rainy afternoon, bored siblings team up with the Cat to “find the fun in every mess.” • New characters: The trailer teases Dr. Seuss deep cuts—including Yertle the Turtle graffiti and a cameo from Horton the Elephant—suggesting a shared “Seussiverse” the studio hopes to expand. • Release plan: The animated comedy is slated for March 6, 2026, in theaters and on Max 45 days later, following the studio’s “event animation” window. Why Bill Hader fits the Cat Hader’s elastic voice work (“Inside Out,” “Cloudy with a Chance of Meatballs”) lets him bounce from playful purrs to gleeful mayhem. In a press statement, the actor said he aimed to blend “a little Bugs Bunny, a little Groucho Marx, and a lot of Seussian rhyme” into the performance. Fans online are already clipping the line “I told you I’d make it rain fun” for reaction memes. Creative team and production facts • Directors: Alessandro Carloni (“Kung Fu Panda 3”) and Erica Rivinoja (“South Park”) wrote and helm the film. • Animation style: A painterly, hand-inked look mimics the thick outlines of Seuss’s 1957 illustrations while layering 3-D depth. • Music: Oscar-winning composer Trent Reznor teams with Atticus Ross for a playful, orchestral-meets-synth score. Social-media buzz driving search traffic Within an hour of the trailer’s launch, #BillHaderCat trended on X/Twitter, racking up 120 k mentions. Google searches for “Bill Hader Cat in the Hat trailer” spiked 2,300 % compared with last week, according to real-time analytics platform Talkwalker.
