Barry Mahon told "Variety" (in the 1 January 1969 issue) that he was negotiating to have 'Garland, Judy' perform narration; however, Garland did not.
The actors playing Jellia Jamb (translator/attendant) and Omby Amby (the soldier who can't find his bullets) were hired for one day only and paid in cash, so Mahon never got their names, even though they have speaking parts.
