Shame, starring Michael Fassbender as “an emotionally stunted sex addict” (is there any other kind?); The Iron Lady with Meryl Streep’s spot-on Margaret Thatcher impersonation; Charlotte Rampling: The Look, a “self-portrait through others” has the screen icon talking to artist friends and collaborators Peter Lindbergh, Paul Auster, Juergen Teller, and others; and Dragonslayer, a brutal punk-rock documentary from Tristan Patterson and executive produced by indie-maverick Christine Vachon that “follows the transgressions of a lost skate punk falling in love in the stagnant suburbs of Fullerton, California, in the aftermath of America’s economic collapse.”
