Dr. Seuss's classic 1954 book Horton Hears a Who has entertained generations of children and served as the inspiration for a 26-minute, 1970 television special Dr. Seuss's Horton Hears a Who and the 2000 Broadway musical "Seussical: The Musical". This 2008, full-length animated movie features the voice talents of Jim Carrey as Horton, Steve Carrell as the Mayor of Whoville, Carol Burnett as the Kangaroo, and Jesse McCartney as JoJo and promises to delight a whole new generation of children and their parents and grandparents. The technological wonders of computer animation have allowed 20th Century Fox Animation to bring to life the wacky, colourful Whoville with its minute inhabitants and the lush Jungle of Nool with its host of distinctive animals and the result is a rich, fantastical world of wonder worthy of Dr. Seuss' own imagination. All the major plot elements of Dr. Seuss' book are present, with Horton hearing the faint cry for help from a tiny dust speck atop a small clover and doing his best to protect the inhabitants of that small civilization of Whoville despite the disbelief, disdain, and persecution of his fellow animals. The feel of Dr. Seuss' original rhyming prose is partially preserved in the sparse narration by Charles Osgood that's interspersed throughout the film's dialogue and the overarching themes of staying true to one's convictions and the celebration of the power of perseverance, imagination, and kindness come through loud and clear. Horton Hears a Who is a fun rendering of a classic Dr. Seuss story that's sure to entertain viewers of all ages. --Tami Horiuchi,
