Thanks! I was going to post about this. The 1938 cartoon 'Porky's Duck Hunt' was co-directed by Ben 'Bugs' Hardaway, and was the first time a rabbit character appeared in a Warners Brothers cartoon. As various directors and animators used the rabbit character he evolved, and in the 1941 the cartoon 'A Wild Hare', directed by Tex Avery, he turned into the Bugs Bunny we know today. Compare the Clark Gable scene where he leans against a fence post eating a carrot while talking to Carole Lombard to the scene in 'A Wild Hare' where Bugs Bunny eats a carrot while casually talking to Elmer Fudd. (go to the 2:30 mark)
