Ingmar Bergman’s Persona, from 1966, explores the relationship between an actress who has become mute, played by Liv Ullman, and the nurse who is in charge of her care played by Bibi Andersson. The pair travel to a cottage on the beach where their personalities begin to conflict and blend.

The unsettling film contains several experimental elements, as well as images that are outside of the main narrative, that provide more questions than answers.
