The Wizard of Oz 1933

This animated early version of the The Wizard of Oz was never released in theaters because it was filmed in Technicolor, but didn't get a release from the Technicolor Corporation. The use of black-and-white in the Kansas scenes and color in Oz was later used in the live-action film of 1939, but the story is quite different. Read more about the production at Wikipedia.
