PERSONA
TCM, 1:50 a.m. ET
Ingmar Bergman wrote and directed this 1966 character study, which elevated Swedish cinema to an internationally recognized source of existential angst. (Bergman had been doing such films for a decade, but this one really caught the zeitgeist. Woody Allen would mine it for comedy for years afterward.) In Persona, Liv Ullman plays a traumatized actress who will not speak, and Bibi Andersson plays the nurse who gets to know her patient so well, their personalities begin to merge and trade. A rarely televised classic.
