Persona

This genre-blurring, minimalist masterpiece from Ingmar Bergman follows a young nurse (Bibi Andersson) and her patient (Liv Ullmann), an actress who has mysteriously gone mute. The women retreat to a seaside cottage to aid the actress's rehabilitation, but the intimacy of their emotions and motivations embroil them in a stranger, stronger bond. A classic of world cinema, Persona has long been considered one of the major works of 20th century art.
