Henri-Georges Clouzot's masterwork builds suspense the slow way: stranded men in a dead-end town, then a brutal job offer, then 150 minutes of trucks and explosives. It remains the gold standard for set-piece tension and a film Hitchcock openly envied.
Mario survives the impossible truck run only to dance ecstatically off a mountain road on the way home. Clouzot ends his survival thriller by killing the survivor in a sweep of joy. The shot rhymes the truck and the music in one final irony.
