When Milos Forman was casting the mental patients in "One Flew Over the Cuckoo's Nest" he looked for unfamiliar faces. One of those who made the biggest impression was the remarkable Sydney Lassick. But it was not his first screen appearance. Ten years earlier he had played the Fairy Godfather in this ridiculous breast-obsessed nudie musical. Perhaps it is not surprising that it didn't lead to further movie parts. He apparently didn't make another movie until "Cuckoo's Nest".
While Lassick provides the main curiosity value in a pretty terrible movie, the film as a whole does provide plenty of "what were they thinking!" entertainment value. The songs are terrible and it all comes across like a pantomime for intellectually challenged adults. There isn't even a hell of a lot of nudity, which after all was the main selling point. But it is unique.
The trend for making "adult" versions of fairy stories, often with song and dance numbers, would continue, peaking in the late seventies with Albert Band's production of "Cinderella" (1977), which was much slicker than this one, but not necessarily any more entertaining.
