In his illuminating study of Psycho, Raymond Durgnat provided a minute analysis of its unfolding narrative, enabling us to consider what happens to the viewer as he or she watches the film, and to think afresh about questions of spectatorship, Hollywood narrative codes, psycho-analysis, editing and shot composition. In his introduction to this edition, Henry K. Miller presents A Long Hard Look at 'Psycho' as the culmination of Durgnat's decades-long campaign to correct what he called film studies 'Grand Error'.
