Lulu (1962)

Dr. Schön picks up a flower girl, gives her a make-over and marries her off to a rich friend with a weak heart. After the predictable fatality the girl marries an artist who is then driven to suicide. Then Dr. Schön succumbs to her charm himself with no better luck. After a few further affairs the girls ends up penniless in London and is murdered by Jack the Ripper. Based on the same Wedekind plays that served as a basis for Pandora's Box, this looks like a seminal film, midway between Pabst and Fassbinder.
