Walt Disney had vision and a grand horizon, but no one ever credited him with genius in the drawing and animation department. His early successes were due to Ub Iwerks. His 1929 "Skeleton Dance" was probably the first great animated film. Creative differences drove him away from Disney where he had his own shop for a while... but lacking the promotion skills of Disney, he floundered. Eventually he was to come back to Disney, Inc. But in the last throes of his independence, he remade "Skeleton Dance" in color and with the addition of brilliant new effects he had invented.
