Despite a contract with MGM to distribute his cartoons, and the introduction of a new character named “Flip the Frog”, and later “Willie Whopper”, the Iwerks Studio was never a major commercial success and failed to rival either Disney or Fleischer Studios. Newly hired animator Fred Kopietz recommended that Iwerks employ a friend from Chouinard Art School, Chuck Jones, who was hired and put to work as a cel washer. The Flip and Willie cartoons were later distributed on the home-movie market by Official Films in the 1940s. From 1933 to 1936, he produced a series of shorts (independently distributed, not part of the MGM deal) in Cinecolor, named "ComiColor Cartoons". The ComiColor series mostly focused on fairy tales with no continuing character or star. Later in the 1940s, this series received home-movie distribution by Castle Films. Cinecolor produced the 16 mm prints for Castle Films with red emulsion on one side and blue emulsion on the other. Later in the 1970s Blackhawk Films released these for home use, but this time using conventional Eastmancolor film stock. They are now in the public domain and are available on VHS and DVD. He also experimented with stop-motion animation in combination with the multiplane camera, and made a short called "The Toy Parade", which was never released in public. In 1936, backers withdrew financial support from the Iwerks Studio, and it folded soon after.
