Merrie Melodies - Horton Hatches the Egg (1942)

Horton Hatches the Egg is a 1942 ten-minute animated short film based on the 1940 book of the same name by Dr. Seuss (and the first cartoon based on Dr. Seuss' work), by Leon Schlesinger Productions, released as part of Warner Bros.' Merrie Melodies series. The short, like many cartoons at the time, and in contrast to the original children's book, was more adult-oriented and was directed by Bob Clampett. Kent Rogers voiced Horton as well as the Peter Lorre fish, Sara Berner voiced Mayzie and the elephant bird, Frank Graham narrated, and Mel Blanc performed most of the other voices.
