Alfred Hitchcock more than any other auteur in the 20th century understood the combination of sound when paired with emotion and suspense.

Added to that was his uncanny understanding of branding and marketing for example he once locked the doors of the cinema during the premiere of Psycho. If you don't love Hitchcock, you're about to, as the new documentary My Name is Alfred Hitchcock explores the sometimes malevolent art of Hitchcockian cinema.
