MOVIES

Billy Jack Tom Laughlin retrospective The bizarre grit of lowbrow 1970s cinema is perfectly embodied in writer-director-actor Tom Laughlin’s 1971 film. The movie, which follows the path of righteous destruction cut by a mystic ex-Green Beret with mad karate skills, remains a cult classic. It will be screened with another Laughlin classic, “Born Losers,” at the Cinefamily, with Laughlin as the guest of honor and Process Media and Filter magazine as hosts. The Cinefamily, 611 N. Fairfax Ave., L.A. 8 p.m. $12. (323) 655-2510, https://www.cinefamily.org.
