The document discusses conventions established in Alfred Hitchcock's Psycho that were influential for subsequent horror and thriller films. It analyzes the use of distorted titles representing Norman Bates' broken mind, tense music to create sudden tension, and camera techniques like panning shots that could make the events seem universal. The document then examines how the film The Secret Window applies some of these same conventions through its camerawork, sound, titles, and mise-en-scene while also breaking conventions by starting with action rather than building tension slowly.
