Director/Producer Erwin C. Dietrich had some trouble with the Hells Angels chapter in Switzerland. One of their girls had a small supporting role (nude scene) in the movie and didn't like her appearance on screen (cellulite). So Hells Angels ordered Dietrich to cut those scenes, otherwise they'd raid cinemas showing the movie. Several cinemas in Switzerland had to show this movie under police protection. Finally Dietrich paid a considerable amount of money so Hells Angels Switzerland would leave him alone.
Asked about the explicit sex scene played by Vivian Weiss, director Jack Hill said, "That might have been one of those things where I said 'cut' and they did not. I do remember the scene when the guy's dick was showing-I almost walked out there too [laughs]. The production crew was just ignoring me and the cameraman kept shouting, 'Fuck her! Fuck her!' It was one of these things where they didn't rehearse and they just kept rolling."
Although producer Roger Corman was originally to be involved with this film, he pulled out before production began. However, after it was completed, the film's producer, Erwin C. Dietrich, nevertheless advertised it in Europe as a Roger Corman film. The matter eventually wound up in court and Dietrich was ordered to stop advertising it as a Corman film when Corman had nothing to do with it. However, the "damage" was done, and to this day many European film historians mistakenly include this in Corman's filmographies.
