The Art of Murder
B
efore the "shower scene" in Psycho, Alfred Hitchcock had directed only three other sustained murder sequences. The vast majority of murders in Hitchcock's movies occur either off-screen, or they are as brief as the flash of a gun. The three prolonged sequences prior to Psycho include the stabbing of Crewe in Blackmail, the stabbing of Swann in Dial M for Murder, and the strangling of Miriam in Strangers on a Train.
