In the film Psycho, Alfred Hitchcock uses various cinematic techniques to create tension and suspense. These include editing, cinematography, mise-en-scene, and performance. Through quick cuts and camera angles during the famous shower scene, editing builds tension by shocking the audience. Cinematography creates an unsettling tone through point-of-view shots and the use of taxidermy. Mise-en-scene foreshadows upcoming events and builds an isolated, ominous setting. Finally, Anthony Perkins' performance as Norman Bates leaves the audience unsettled and curious about the killer's identity. These techniques are used effectively throughout the film to generate tension and suspense.
