This Hitchcock classic contains extra-generous helpings of the ingredients that make his films so unmissable. Action, intrigue, romance and comedy are blended throughout with consummate skill; the attack by the crop-dusting plane and the finale on Mount Rushmore are simply the icing on the cake. Rarely did Hitchcock have as much fun with his favourite "innocent in peril" theme or make such inventive use of famous landmarks. In his fourth and final collaboration with the "Master of Suspense", Cary Grant is the personification of suaveness as a hapless advertising executive who is forced to take on a nest of enemy agents, led by a rather disengaged James Mason.

Advertising man Roger Thornhill is mistaken for a spy, triggering a deadly cross-country chase.
