I'm telling the truth...i thought this movie would be a stinker from the teaser trailer and TV spots but this surprised me as well as every other person at the screening. It even surprised the film operator! Anyway, the great voice cast voiced by some great actors, Jim Carrey and Steve Carrell and even Seth Rogen(which is a nice change for him, from all his dirty cursing roles(don't get me wrong,i love him in those roles)). Dane Cook was a little annoying, but it wont really distract you from the big picture. In this film, Steve Carrell is the Mayor of Who-Ville, a town on a dandelion full of tiny people. Jim Carrey plays Horton...who is a elephant who finds a dandelion, picks it and figures out he must protect it because of Who-ville. Seth Rogen plays a rat like creature in his role. A supporting cast with Amy Poehler, Jonah Hill, Dan Fogler and much more. This film is great for little kids and a surprising delight for adults.
