The granddaddy of them all was Snow White and the Seven Dwarfs. The film stands not only as the first feature length animated film ever, but the very first studio project dubbed "Disney's Folly" by naysayers. Looking at the first Mickey Mouse cartoon Steamboat Willie which was released in 1928, it is hard to believe that Snow White came out just nine years later. An amazing feat! But then, Walt Disney was an amazing man!
