Is a person a person, no matter how small? Horton the elephant (voiced by Jim Carrey) certainly thinks so, even though no one else in the jungle can see or hear the tiny residents of Whoville, who have all trusted the pachyderm to protect their microscopic home from harm. Based on the beloved Dr. Seuss book, this animated fable also features the voices of Steve Carell, Carol Burnett, and Seth Rogen among its "who's who" of talents. 86 min. Widescreen; Soundtrack: English.
