"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.
