It's a satire based on the book by Terry Southern, a significant player in the counter-culture movement of the 1960s. It attracted a quality cast, so I assume it was considered of great importance among cult viewers of the era, but it's nothing more than a string of farcical sexual encounters and a number of great men embarrassing themselves thrown haphazardly together. That may well have been Dir. Christian Marquand's intention, but for me the absurdity never really satisfied.
