In 1960, Alfred Hitchcock was already famous as the screen's master of suspense (and perhaps the best-known film director in the world) when he released Psycho and forever changed the shape and tone of the screen thriller. From its first scene, in which an unmarried couple balances pleasure and guilt in a lunchtime liaison in a cheap hotel (hardly a common moment in a major studio film in 1960), Psycho announced that it was taking the audience to places it had never been before, and on that score what followed would hardly disappoint.
