They finally got Dr. Seuss right in this warm-hearted and heart-warming story of the elephant who is “faithful 100 percent” and the world on a little speck of dust that he rescues.

Jim Carrey provides the voice of Horton, an elephant with a gentle soul who teaches the jungle animal children. When a frail plant is carelessly trampled underfoot, he stops to pat it carefully back into the ground. And when he hears a tiny voice coming from a dust mote, he races after it to tenderly place it on a clover. He finds a way to communicate with the voice, which belongs to the Mayor of Whoville (Steve Carell). Each is surprised to find out that there is a world beyond the one he thought of as everything there was.
