Journey Back To Oz is an official animated sequel to the 1939 MGM film The Wizard of Oz. It is loosely based on L. Frank Baum's second Oz novel, The Marvelous Land of Oz. Baum received no screen credit.
Produced in 1964 by the Filmation studio, copyrighted 1971, released in 1972 in the UK and 1974 in the U.S.), it features the voice and singing debut of Liza Minnelli as Dorothy (played in the previous 1939 film by her late mother, Judy Garland). Other voices were by Milton Berle, Mickey Rooney, Paul Lynde, Herschel Bernardi, Paul Ford, Danny Thomas, Margaret Hamilton (also from the 1939 film, but now playing Aunt Em rather than the Wicked Witch of the West), and opera singer Risë Stevens as Glinda.
Thanks to another twister, Dorothy is knocked unconscious and once again dreams herself into the land of Oz, where she meets new characters such as Pumpkinhead, Woodenhead Stallion (a carousel horse loosely based on the Sawhorse), Mombi (another wicked witch who has now taken over the land of Oz, voiced by Ethel Merman), and killer elephants. The Wizard was nowhere to be found.
