Alfred Hitchcock’s prototypical - wrong man - adventure, the dazzling 39 STEPS is considered the British director’s true commercial and artistic breakthrough. Presaging such tense against-the-odds thrillers as The Man Who Knew Too Much and North by Northwest, it follows the exciting exploits of Richard Hannay (Robert Donat), a dapper everyman who ends up on the run after his identity is mistaken for that of a murderer.
