Some films are carried by dialogue and acting so gripping, so razor-sharp, that the mise en scène fades into the background, and Garde à vue is one of them. Ventura and Serrault deliver a masterclass in tension, their face-off hypnotic and relentless. Everything else is stripped down, almost ghostly, so much so that even Romy Schneider feels like an apparition drifting through the fog. A haunting tour de force.
