One of the first films to receive an "X" rating from the Motion Picture Association of America (MPAA) through their then-newly-formed ratings board, the Classification and Rating Administration (CARA).
In the documentary Skin: A History of Nudity in the Movies (2020), Erica Gavin was asked if appearing naked in films affected her career. She said said "Well, it didn't really affect my professional career, but it affected me personally because when I went to the premiere, the first time I saw myself that big on a giant screen, I started picking my body apart, and I didn't like the way I looked." She became deathly anorexic just from how she saw herself on the big screen, and almost died.
Erica Gavin said in an interview that Russ Myer was very protective of women, especially when filming nude scenes. "For one thing, I don't remember ever being totally nude. I don't know, because Russ was not one to shoot below the waist. Russ didn't really appreciate the woman's body from the waist down. He didn't think that there was anything that gorgeous to show. His films came from a different direction than porno. Basically he was not looking through a camera; he was looking through a peephole. I think that's why his films were so good. He was a true voyeur."
According to Wikipedia, Charles Keating, the financier convicted of wire fraud was incensed by the release of this film. An amateur pornography vigilante, he used his considerable pre-conviction influence to have the movie banned in Cincinnatti Ohio, his one-time headquarters. According to the article, the film remains banned in that city to this day despite it being easily available on dvd and on the Internet.
In a 1969 interview, Russ Meyer said he started looking for actresses with big breasts but not as massive as previous films with this movie. "The big undeveloped (no pun intended) market for us right now is the female audience," he said. "The reason I, A Woman (1965) did so well was because women wanted to see it. But a woman can't identify with an actress who's unreasonably built. My actresses will always be built but not unreasonably, you know?"
