Sundance Q&As are often pretty staid affairs, but yesterday's premiere of Craig Zobel's new film "Compliance" got a lot more explosive than usual, with the director subjected to claims of misogyny and an audience member who accused him of getting off on actress Dreama Walker's nudity and humiliation. ("I've never seen a response like that to a film," said one viewer.) The film tells the story of a young woman (Walker) at a fast food chicken joint who is subjected to an extended strip search (and eventually sexual assault) by an older, female manager after a man calls claiming to be a cop who's investigating accusations of theft against the young lady. Amazingly, Zobel based it on a number of real-life incidents he'd read about, as well as the infamous Milgram experiments at Yale, which measured test subjects' willingness to torture others based on the demands of authority. That has made the last day or so quite a ride for the young, soft-spoken director, whose previous film, "The Great World of Sound", was a gentle, touching comedy that had a decidedly less controversial reaction at the 2007 Sundance Festival. He spoke to Vulture about what it was like to get yelled at during his premiere.
