The document analyzes the editing and sound techniques used in the famous shower scene murder in Alfred Hitchcock's Psycho. It discusses how Hitchcock uses a slow entrance followed by quick cuts, totaling 78 cuts in 45 seconds, to shock the audience with both the event of the murder and its brutality. The scene is made more intense through the use of diegetic sound, with the running shower water drowning out other noises before the curtain is ripped aside to reveal the murder.
