Alain Delon, Catherine Deneuve, and Richard Crenna star in Melville’s last feature, a consummate cops-and-robbers tale of remarkable set pieces and an even more remarkable sense of nihilism. A windswept seaside bank robbery, a hospital breakout, a giddily ludicrous train heist: Melville’s nearly wordless action scenes are miracles of staging, timing, and movement, and prove that suspense can build from not more action, but less. Similarly, the dialogue is as colorless as the autumnal surroundings, yet Un flic still generates an inescapable mood of moral decay, constant surveillance, and brooding despair. Sartre by way of Simenon, it’s a fitting swan song to the director’s career.
