The Man Who Knew Too Much (1934)

While on vacation in Switzerland, British couple Bob and Jill Lawrence witness the murder of one Frenchman Louis Bernard, inadvertently leading to the kidnap of their young daughter. A single bullet unravels a criminal conspiracy in one of the undeniable triumphs of Hitchcock’s British period. Notable for its sardonic tone, oscillating between comedy and nail-biting suspense, an iconic-looking Peter Lorre anticipating many Bond villains and frequent outbursts of rhythmic, expressionistic montage that transform banal British settings into nightmarish situations, this thriller classic culminates on an oft-imitated concert hall sequence so captivating that Hitchcock remade it himself!
