One day, Horton the elephant hears a cry from help coming from a speck of dust. Even though he can't see anyone on the speck, he decides to help it. As it turns out, the speck of dust is home to the Whos, who live in their city of Whoville. Horton agrees to help protect the Whos and their home, but this gives him nothing but torment from his neighbors, who refuse to believe that anything could survive on the speck. Still, Horton stands by the motto that, "After all, a person is a person, no matter how small." Written by Griffin84

In order to save the speck of dust, Horton quickly sucks up some water from the pond and swallows it. However, elephants can't drink through their noses. They use them to squirt water into their mouths when they're thirsty. Elephants also can't climb trees, stand upright, hold objects with their front feet, move their ears like hands, or talk. However, Horton is a Dr. Seuss-style elephant from a fictional world, so all these stunts are feasible. See more »

Knock knock, whos are there
14 March 2008 | by See all my reviews

It's interesting to see a pretty big creature like Horton concerned with protecting the tiniest creatures of all...even if the others in the jungle of Nool may not believe that's he's right about all those tiny people on the speck (well, maybe Rudy, the Sour Kangaroo's son, may think he could be right...)

Lovable characters like Horton, who can be serious at times (and is truly determined) but also wild-and-crazy, full of imagination and whimsy. Like the mayor, who is determined to protect his city from the dangers they're now being exposed to (who will protect the protector? "A giant elephant, up in the sky!... Don't bother to look, he's invisible...")

Had to admit a tear--of joy--rolled down my cheek at the end. Highly recommended! The look of the film is visually stunning, and a good voice cast (CBS Radio's Charles Osgood narrates; the mayor and his wife are Steve Carrell and Amy Poehler, and Jim Carrey of course is Horton. Carol Burnett plays the sour Kangaroo. And Jesse McCartney voices JoJo, and let's just say he didn't have too many lines to remember :)
