Persona is a 1966 Swedish psychological drama film written and directed by Ingmar Bergman and starring Bibi Andersson and Liv Ullmann. Persona’s story revolves around a young nurse named Alma (Andersson) and her patient, a well-known stage actress named Elisabet Vogler (Ullmann), who has suddenly ceased to speak. The two move to a cottage, where Alma cares for and talks to Elisabet about intimate secrets, and begins having trouble distinguishing herself from Elisabet.
Bergman wrote the film with Ullmann and Andersson in mind for the lead parts, and some idea of exploring their identities, and shot the film in Stockholm and Fårö. Often categorized as a psychological horror, Persona deals with themes of duality, insanity, and personal identity.
In its release, the film was subject to cuts because of its controversial subject matter but received positive reviews. It won the award for Best Film at the 4th Guldbagge Awards and was Sweden's entry for consideration for the Academy Award for Best Foreign Language Film. Many critics consider it one of the greatest films ever made, and it has been the subject of a vast amount of analysis, interpretation and debate. The film has influenced many later directors, such as Robert Altman and David Lynch.
