In the movie "Horton Hears a Who," Jim Carey is the voice of Horton, the inventive and imaginative elephant who teaches his young friends about the amazing world around them. One day Horton, with his big ears, hears a voice on a speck of dust floating in the jungle air. Horton catches the speck on a dandelion, and begins to talk to the speck. The Mayor of Whoville (voice Steve Carell) talks to Horton, and the Mayor can not believe that there is something bigger than his world. After there are several climate changes (darkness in the middle of the day and snow in summer) that occur in Whoville, the Mayor believes that his world is in great danger. The Mayor tries to warn his people of the impending doom, but everybody ridicules him and thinks he is crazy. Horton is getting the same reaction from everyone who thinks he is also crazy; especially the kangaroo (voice Carol Burnett) who wants to get rid of the speck, and Horton's wild ideas. Horton defends the speck by saying that "a person's a person, no matter how small." Horton talks to the Mayor and tells him that he is going to put the speck in a safe place and out of danger. Douglas Young (the-movie-guy)
