Los Angeles Plays Itself Cal Arts professor and filmmaker Thom Andersen’s 2003 film essay about the myriad uses of the City of Angels as both location and character in everything from “Rebel Without a Cause” to “Who Framed Roger Rabbit?” and “The Big Sleep” to “L.A. Confidential” is a must-see for Angeleno film-nerds. Exhaustive in his research and defense of his beloved hometown, Andersen presents a novel take on the Hollywood establishment’s (mis)use of the city’s Modernist treasures. Discussion with Anderson after the film. American Cinematheque, Aero Theatre, 1328 Montana Ave., Santa Monica, (310) 260-1528. Sep. 3, 7:30 p.m. $12; $8 for Cinematheque members.
