This movie ran afoul of the Maryland censor in 1964, who didn't object to the nudist camp scenes, but took offense to the scene showing the topless girls on the boat (because nudist camps were on private land; nudity on a boat was in public). The film ultimately won on appeal.
Though the three main actresses' visible bikini tan lines belie their supposed love of naturism, the colony members they visit are apparently real-life enthusiasts of all ages and sizes, who play volleyball, swim and go fishing in the unashamed buff, lending this film a little authority in the face of other films which cheated by populating their sunshine camps with often haggard-looking topless dancers.
The film was directed under the pseudonym Alan Overton by Leo Orenstein, a playwright and a veteran CBC director/producer who was known for his dramatic pieces on anthology programs like Quest, Encore and CBC Television Theatre. He was hired by Ted Leversuch, a British filmmaker who was to become Canada's most prolific purveyor of cinematic sin in the 1960s, with forgotten films including French Without Dressing and Sex and the Lonely Woman Part 2.
