So it's no secret that Steve Carell hasn't always made the best choices when it comes to movie roles. The same could probably be said of some of Jim Carrey's choices as well, so there could be a lot riding on both their reputations for the big-screen adaptation of the classic Dr. Seuss story, Horton Hears a Who!. Erik had brought us the first teaser back in July and now a full feature trailer has been released.

Horton is based on the 1954 children's story about a microscopic world that gains an elephant as their protector. Over the years the story's moral of "a person's a person no matter how small" has been interpreted as a response to the McCarthy anti-communist era and the importance of treating the "least of us" with a little care and respect -- pretty heavy for a kid's book, I know, but it does make me long for the days when children's entertainment had more going for it than tie-in deals. The film stars Carell as the feisty mayor of Whoville and Jim Carrey as their elephant advocate. The film has a solid supporting cast that includes some truly hilarious people; namely Will Arnett, Seth Rogen, Jonah Hill, Amy Poehler, and Carol Burnett.

So even if you are not the biggest fan of kid's movies, after watching this trailer, you can't deny this is one snazzy looking movie with some big-name comedic talent. But I guess everyone said the same thing about Bee Movie, and we all know how that turned out. Horton Hears a Who! arrives in theaters on March 14th, 2008.
