On the fifteenth of May, in the jungle of Nool, in the heat of the day, in the cool of the pool. He was splashing...enjoying the jungle's great joys...When Horton the elephant heard a small noise.

With his signature evocative and rhyming text, writer and cartoonist Dr. Seuss, an American treasure whose books have delighted generations of young people, opens one of his most beloved tales, Horton Hears a Who!

Now, over fifty years since Seuss, whose real name was Theodor Seuss Geisel, published this perennial favorite, the makers of ICE AGE and comedy giants Jim Carrey and Steve Carell, bring it to life in a way never before experienced. For the first time, a motion picture transports audiences into Dr. Seuss' incredible imagination, through state-of-the-art CG animation. DR. SEUSS' HORTON HEARS A WHO! (TM) is Seuss as you want to experience his work at the movies - and as it was meant to be seen.

The film, like Seuss' book, presents an imaginative elephant named Horton (Carrey) who hears a faint cry for help coming from a tiny speck of dust floating through the air. Although Horton doesn't know it yet, that speck houses an entire city named Who-ville, inhabited by the microscopic Whos, led by the Mayor (Carell). Despite being ridiculed and threatened by his neighbors, who think he has lost his mind, Horton is determined to save the particle...because "a person's a person, no matter how small."

Horton's eight-word explanation for his actions embodies an idea both simple and profound, and which means so much, to so many. The film provides more food for thought, having Horton explains to his skeptical friends: "If you were way out in space, and you looked down at where we live, we would look like a speck."

Then there's Horton's code...his motto... that, "an elephant's faithful 100 percent" - pointing to his honesty and determination to never abandon his mission to find a new home for the speck that houses the incredible world of Who-ville.
These philosophical declarations point to Seuss' unique ability to take complex issues and boil them down into understandable thoughts that anybody, at any age, could understand.

It all comes together through the vision of a master storyteller, the magic of computer animation, and the special alchemy of three generations of comedy stars - Carrey and Carell are joined by the legendary Carol Burnett, as well as cutting-edge talents Will Arnett, Isla Fisher, Amy Poehler , Seth Rogen and Jonah Hill - to create an all-audience comedy event.
