I remember seeing this on Network TV back in the early 80's and being surprised they got away with the swearing and nudity. I was given a VHS copy as a gift a few years later and it matched what was on TV (without commercials). A couple of decades after that and Netflix (and, later, YouTube) had a version with the language - but no nudity. Then YouTube has one that had nudity but no language. I feel like there must be a "complete", full length version out there, somewhere. Not that either really make the story any better or worse as it's still a great film. The book is over 1,000 pages and a full telling of the account ran at least 3 - 4 hours.
