Question: horton hears a who how the grinch stole christmas?
Answer: No, Horton Hears a Who and How The Grinch Stole Christmas are not the same. However they do have some simliarites. For instance, in both movies, the primal setting of the story is Whoville. In Horton Hears a Who, Horton tries to find a safer place for the Whos to live (who incidentally live on a speck).
