Long before Matthew Barney was befuddling audiences with his inscrutable Cremaster series, Chilean director Alejandro Jodorowsky was the O.G. of “cinema-as-prog-rock” filmmaking. Originally an avant-garde theater director in the early ’60s—one of his more infamous pieces supposedly involved both animal sacrifice and a nude woman with live snakes taped to her breasts—Jodorowsky was uniquely qualified to make the big-screen equivalent of The Lamb Lies Down on Broadway. It shows in his first major film, El Topo, a surrealist Western that falls squarely between Luis Buñuel and Sergio Leone as it follows a black-leather-clad gunfighter on a quest to defeat four pistol-packin’ shamans. The streets run red with blood as the protagonist encounters a menagerie of limbless midgets, false prophets, and poorly behaved clergy in a series of events that, while never quite meaningful, are at least fascinatingly bizarre. The film screens at 8 p.m. at Dr. Dremo’s Taphouse, 2001 Clarendon Blvd., Arlington; sponsored by the Washington Psychotronic Film Society. Free. (202) 736-1732. (Aaron Leitko)
