Check out Ingmar Bergman’s film Persona. Amherst Cinema has been celebrating the 100th anniversary of the Swedish master’s birth. Hooray! Persona is another trippy Bergmanian piece wrought with WTFs. Liv Ullmann plays Elisabet, an actress who, without reason, has gone mute. Bibi Andersson’s, character, Alma, is the exact opposite; a loquacious nurse hired to take care of Ullman at a remote cottage. That’s when the single white female stuff hits the fan. Terrible secrets, covert plans, and downright insanity mix to make this movie a total head-scratcher. If you miss the experimental prologue you’re probably better for it. Amherst Cinema, 28 Amity Street, Amherst. 7 p.m. – 9 p.m.
