Alfred Hitchcock directed a string of masterpieces in the 1950s including "Strangers on a Train" (1951), "Rear Window" (1954), "The Man Who Knew Too Much" (1956), "Vertigo" (1958), and "Psycho" (1960). At the height of this remarkable run came "North by Northwest" (1959), a unique marriage of Hitchcock's trademark suspense and humor. Ernest Lehman, well-known in Hollywood for adaptations such as "Sabrina" (1954) and "The King and I" (1956), wrote the screenplay, his only original work and which is widely regarded as his best.
