The movie never materialized. The cult hit went no where.  But in 1980, when not many thought there was a home for hard-core sadomasochism in the big wide world, I read in one of my old gazetteers that over in Germany a new subculture had formed in which people dabbled in such things.  It wasn't bad at all.  You can only be sick and stupid if you don't know what's good for you.
