Un flic ('A Cop'), also known as Dirty Money, is a 1972 crime thriller film, the last directed by Jean-Pierre Melville before his death the following year. It stars Alain Delon, Richard Crenna and Catherine Deneuve. Delon had previously portrayed criminals in Melville's Le Samouraï (1967) and Le Cercle Rouge (1970), but in Un flic, his role is reversed, and he plays the title character.
