Psychoanalytic theory in film studies explores how movies tap into our unconscious minds. It examines hidden meanings, symbols, and desires in cinema, drawing on Freudian concepts like the id, ego, and superego. This approach gained popularity in the 1970s, with theorists like Christian Metz and Laura Mulvey applying psychoanalytic ideas to film. It considers how movies reflect collective unconscious thoughts and how viewers engage with films on a subconscious level.
