List of the best psychological thrillers and mystery films ever made. Though a variety of definitions for the "psychological thriller" genre have been offered, there is no universally accepted set of guidelines. In general, psychological thrillers integrate personal character elements into mystery and suspense films, essentially toeing the line between a dramatic character study and the sort of plot structure you'd expect from a detective movie. Many psychological thrillers resemble traditional thrillers or suspense films, only with a personal, internal antagonist rather than a traditional movie villain. (For example, "Repulsion" or "The Conversation," in which the plot is moved forward by the main character's growing paranoia and madness.) In many films of this type, the solution to the main character's conflict comes in the form of altering their perspective or discovering some buried truth about themselves and their past, rather than winning a fight or battling an opponent.
Many psychological thrillers play around with the main character's backstory, or make use of an unreliable narrator. Films like Christopher Nolan's "Memento" present the audience with one perspective on the story, and then generate suspense by showing the ways in which "reality" contrasts to this perspective. (This sometimes, but not always, results in a "twist" or surprise ending based on the difference between the main character's perception and that of outside observers.) Several Alfred hitchcock films utilize this technique, particularly movies like "Spellbound" and "Marnie," in which the story concerns a character becoming mentally well after years of madness and confusion.This list contains the very best films from the psychological thriller genre.
