Le Doulos is a 1962 French crime film written and directed by Jean-Pierre Melville, adapted from the novel of the same name by Pierre Lesou. It was released theatrically as The Finger Man in the English-speaking world, but all video and DVD releases have used the French title. Intertitles at the beginning of the film explain that the French title refers both to a kind of hat and to the slang term for a police informant.
