obscure b movie on BBC tonight

Over the years I have watched some crazy films on tv,sometimes I keep seeing the same ones but tonight this one popped up and I don't recall seeing it before.

Believe me I think I would remember if I had seen it before,it is so 1970s(well 1970 to be exact).

Everybody smokes,skirts and dresses are short,sexism had not been invented,it is a historical curio,but I would rather see THE EXECUTIONER with JOAN COLLINS which is the same sort of thing but higher class.
