Dr. Petiot 1990

Directed by Christian de Chalonge

A true story shot in a German Impressionistic style. In France during the Nazi occupation, Dr. Petiot (Michel Serrault) offered to help Jews escape the Nazis. They would come to his house, and he would kindly give them lethal "vaccinations" for their anticipated travel to Argentina. Then he would steal everything the brought with them (in addition to their up-front payment to him) and burn their bodies in his home-made crematorium.
