This Rascal of Anatole (1952)

Anatole, quivering nostrils and greedy lips, is the resourceful clerk of Mrs. Paufilat, a butcher. It takes a fancy to take on the identity of the Paufilat son, Paul. He must then undergo the assaults of the tumultuous Germaine, exhilarated by the money of Paul Paufilat.
