A brand-new film adaptation of literary master Dr. Seuss's bestselling classic "The Cat in the Hat" is set to hit the big screen, with the second official trailer and a new poster (below) recently released.

"The Cat in the Hat" carries the major responsibility of launching Warner Bros. Pictures' planned "Dr. Seuss Animated Film Universe." Alongside this film, the studio is also developing adaptations of "Thing One and Thing Two" and "Oh, the Places You’ll Go!", which will be part of the same interconnected world.

The film is co-directed by Erica Rivinoja (writer, "Trolls") and Alessandro Carloni ("Kung Fu Panda 3"). This marks not only the first animated feature for "The Cat in the Hat" but also its second cinematic adaptation. Universal Pictures previously released a live-action version in 2003, which struggled at the box office and with critics. Warner Bros. Animation has now taken the reins for this new adaptation.
