Wilhelm Reich worked as first assistant to Sigmund Freud, studying orgasmic reflex and human sexuality. But in the ’30s, he was forced to flee Europe after both Nazi and Communist parties attacked and burned his books. Reich ended up in Americabut he did not fare much better here. The Food and Drug Administration banned his work, and Reichwho refused to stop practicingwas subsequently sent to a federal prison, where he would later die. The first third of WR: Mysteries of the Organism is a documentary about Reich’s life and beliefs. From there, the film moves into a collage of seemingly unrelated real and fictitious elements: It includes footage of a man having his penis plaster-casted, interviews with a transsexual about her first experience with a man, stock footage of Stalin and Mao, and a sequence in which a Yugoslav woman attempts to persuade a Russian figure skater that free love is the ultimate revolution. This film was banned in Yugoslavia upon its release. Find out why when it shows at 7 p.m. at the Library of Congress’ Pickford Theater, 101 Independence Ave. SE. Free.
