The classic and beloved story from Dr. Seuss is now a CG animated film from 20th Century Fox Animation, the makers of the Ice Age films. An imaginative elephant named Horton (Jim Carrey) hears a faint cry for help coming from a tiny speck of dust floating through the air. Horton suspects there may be life on that speck and despite a surrounding community, which thinks he has lost his mind, he is determined to save the tiny particle! Jim Carrey and Steve Carell lead an all-star cast in bringing this wonderful family picture to life!
