Another tale of dishonor among thieves and another masterpiece from Jean- Pierre Melville but this one's a little more complicated than most. "Le Doulos" is slang for a hat but in criminal circles it also means a police informer. The informer here is Jean-Paul Belmondo and he seems to be playing one side against the other, police and crooks, but to what end? The movie is tortuously plotted until it's all very neatly and beautifully tied up at the end and it pays homage, not just to the great Hollywood gangster movies, but to such classically poetic French films of the thirties such as "Le Jour se Leve" and "Les Quai Des Brumes". Belmondo is, of course, magnificent and SergeReggiani is suitably fatalistic as the gangster who sets everything in motion. An absolutely essential movie.
