Warner Bros. Animation presented a work-in-progress version of The Cat in the Hat at Annecy Animation Festival. The panel included several clips and a deep dive into the world building of the movie.

• The cat is assigned to Gabby and Sebastian after almost getting fired for endangering the kids he was assigned to.
• Gabby and Sebastian are unhappy after their mom gets a new job and they have to move to somewhere else, leaving everything they loved behind.
• The mom is voiced by America Ferrera.
• The film includes 3 worlds: the real world, Seussʼ world and the boxesʼ world.
• Seussʼ world is where he gets assigned to the kids. It has an absurdist aesthetic and wacky shapes. The whimsy of Seuss is heavily implemented here.
• Seussʼ boss sounded like Giancarlo Esposito.
• The boxesʼ world is the moving boxes of Sebastian, Gabby and the mom coming alive.
• Sebastian is into the ocean so his world is an ocean world.
• Gabbyʼs world is a reflection of her old life before moving. She sees her old street through heavy nostalgia which makes it look better than it actually was.
