On Jan. 24 at The Sentient Bean, the Psychotronic Film Society pays tribute to actress Linda Blair (“The Exorcist”) with a rare presentation of 1984’s“Savage Streets,” a gritty, low-budget exploitation flick with a loyal cult following worldwide. Equal parts sleaze, camp and shock, it’s a violent tale of deadly revenge. Look for “Animal House” Dean Wormer himself, John Vernon, in a key role. 8 p.m. showtime, with $7 admission for mature viewers.
