FilmBlogsAreUs Classic Favorites is from the Vault of Walt Disney. Steamboat Willie was intended as a parody of Buster Keaton’s Steamboat Bill Jr. Although this was the third Mickey cartoon produced, it was the first to find a distributor, and thus is considered by The Disney Company as Mickey’s debut. Willie featured changes to Mickey’s appearance (in particular, simplifying his eyes to large dots) that established his look for later cartoons and in numerous Walt Disney films. The cartoon was not the first cartoon to feature a soundtrack connected to the action. Fleischer Studios, headed by brothers Dave and Max Fleischer had already released a number of sound cartoons using the DeForest system in the mid-20’s.
