I feel like the only human being left on planet earth who has even *heard* of these incredibly non-PC books....but as a young teenager, I was totally engrossed by the Gor series written by John Norman. (a barbarian world on the other side of the sun where all men are like Conan, and all women are pleasure slaves......but there's more to it than that). The series actually started off as pretty decent "sword and sandal" adventure stories....but about 8 books in it started to degrade into WAAAAAYYYY too much "all women secretly yearn to be owned" philosophy and it just got to be boring.
There was an attempt at 2 films, one with Jack Pallance, and I believe the other had Oliver Reed??? But they were both absolutely AWFUL. One of them was even (deservedly) riffed on Mystery Science Theater 3000. Seriously some of the worst films ever made, and only vaguely touch on the source material. I honestly don't think you could do such a film that was faithful to the source material....the source itself was once viewed as harmless male fantasy fun, but in today's overly PC society, the books would most likely be effectively banned if more people even knew they existed.
