Scorpio Rising is a 1963 Kenneth Anger experimental short film. Motorcyclists, Brando, James Dean, drug use, Jesus, S&M, anal sex, Nazis, public urination, guns, death.... It may be influential, but I'm not finding it an enjoyable movie outside that historical context. The music is fun. At least it's short.
The book 1001 Movies You Must See Before You Die says it's "One of the most influential of all "underground" films". There's no critics score at Rotten Tomatoes, but the audience rating is 52%.
