A proposed live-action feature, The Rainbow Road to Oz, was to have starred some of the Mouseketeers, including Darlene Gillespie as Dorothy and Funicello as Ozma. Preview segments from the film aired on September 11, 1957, on Disneyland's fourth anniversary show.[3] By then, MGM's The Wizard of Oz had been shown on CBS Television for the first time. Theories on why the film was abandoned include Disney's failure to develop a satisfactory script and the positive reception of the MGM film's television screening. Disney ultimately replaced this film project with a new adaptation of Babes in Toyland (1961), which starred Funicello as Mary Contrary.[citation needed]
