Dr. Seuss’ book The Cat in the Hat was published in 1957 on its way to becoming a perennial classic for generations of kids. This will mark the character’s animated big screen debut; Mike Myers starred in a live-action adaptation in 2003.
The movie is the first in a slate of animated projects that Warner Animation and Dr. Seuss Enterprises are developing together.
