The document discusses the genre of psychological thriller films. It defines psychological thrillers as thrillers focused on elements of the human mind that create tension through slow pacing rather than horror. Settings for these films include normal homes and towns but also asylums and woods to play on fears of insanity and isolation. Character conventions include those who are deviant or mentally ill. Narratives often involve themes of fear, insanity, and delusions. Techniques like close-ups, blood, and non-diegetic sound or music are used to build tension. Prolonged shots and camerawork also change audience perception.
