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

When the mayor is telling Horton about his family, he says "I have a beautiful wife, ninety-six daughters and one son." He doesn't mention his son's name. Yet later in the movie, Horton says "The mayor has one son named Jo-Jo." Unless he and the mayor have another conversation in the movie that we don't see, Horton couldn't have known Jo-Jo's name.

14 March 2008 | by (United States) – See all my reviews

I went and saw this movie with my high school drama group, we had recently done Suessical for a school musical and I played the Mayor of Whoville, and I enjoyed the whole thing from start to finish. The cast of this film did an outstanding job with the voices of the characters, Jim Carrey is most notable in my opinion. Steve Carell also did an amazing job as the Mayor of Whoville.It also has good, clean humor that is both funny and suitable for all ages. I laughed through nearly 90% of the film and I didn't see one thing that would be deemed inappropriate for someone young. This movie lives up to the legacy of the book and I don't care what age you are, you will laugh out loud and enjoy this hilarious Dr. Seuss movie.
