Director James Trainor had worked at the
Commonwealth Film Unit and worked in the United States as a documentary director. He wrote the script with his father-in-law, noted Hollywood screenwriter
Howard E. Koch. Konrad Matthaei agreed to help finance the film if he was allowed to play the lead role.
Kamahl, a popular singer, was cast in a lead role. White actor
Ed Devereaux was cast as an Aboriginal character. "If the producers had had the time they undoubtedly would have cast about for an Aboriginal actor," said Devereaux. "But they had to have a man with experience, for there could be no delay - we shot this film fast and furious." Filming began in January 1967 and took place in Outback Australia and at the studios of
Supreme Sound. Location filming took six weeks. ==Release==
