“Dr. Seuss’ Horton Hears a Who!” hits theaters tomorrow, March 14, 2008. Based on the classic children’s book by Dr. Seuss, an elephant named Horton (Jim Carrey) hears a cry for help, except the sound comes from a speck of dust that idly flies by his massive ear. Determined to save whomever or whatever is contained in that dust, Horton is ostracized from his community. In short, they think he’s lost his mind. Rated G! (So few and far between are G-rated movies.)
