Rene the Cane.

"René la Canne" was the second collaboration between Francis Girod and Ennio Morricone, coming after "Le Trio Infernal" (1974) and before "La Banquière" (1980). His film is an adaptation of a story by Roger Borniche about the gangster René Girier and relates the fantastic adventures of a flamboyant mobster (René/Gérard Depardieu) and a maverick police inspector (Fernand la Sournoise/Michel Piccoli), through the 1940s.
