If you haven't seen the 70's Sci-Fi movie Zardoz...DON'T! ...or do... I dunno what you're into.
Here is a user review from IMDB:
"I've seen some weird movies in my time! 'The Holy Mountain', 'Human Highway', 'Men behind The Sun', 'Nude For Satan', 'Pink Flamingos', 'Dune', but NOTHING as weird as 'Zardoz'! Nothing! "
