When it comes to truthful depictions of sex and relationships, where are progressive moviemakers going? Where should they go? What does it take to get it right, and wrong? In his keynote piece "Donald Sutherland's Buttocks," Jonathan Lethem tackles the first question; later, a roundtable of prominent indie moviemakers answer the rest. We'll preview the year in wavemaking, via interviews with visionary new directors and a report from this year's sex-obsessed Sundance Film Festival. We also have some timeless preoccupations on hand: a sex-scene quiz, personal essays about various cinematic fetishes (Sleeper, The Thin Man movies) and a confessional from a self-admitted starfucker. — Michael Martin
