It is quite remarkable that a filmmaker so clearly fascinated by murder and death should have only four extended murder sequences during this lengthy career. This can be partially explained in terms of Hitchcock's belief in the creative power of audience imagination.NOTE 3 Because the mere glimpse, or even threat, of violence is often enough to provide suspense, the actual amount of screen violence can be reduced.
In this essay, I will take a detailed look at murder sequences in Blackmail, Strangers On a Train, and Dial M for Murder and argue that Hitchcock's mastery of cinematic representation builds through these three sequences and comes to a culminating point in Psycho. In looking at these sequences, I will argue that each displays a dominant feature and that this feature is reprised in Psycho.
