Sienna Miller has slammed filmmakers for their disinterest in the story of tragic 1960s muse Edie Sedgwick. The British actress, who played the late star in FACTORY GIRL, insists directors were reluctant to work on the movie because they viewed Sedgwick as the Paris Hilton of her day, Miller says, "They (US filmmakers) were like, 'So, what? In 30 years' time are they gonna make a film about Paris Hilton?' "The thing about Edie was that she was a performance artist. She'd walk into a room and start dancing, start performing. "But the people I've been speaking to missed the point. They're like, 'Okay, rich, socialite, drugs, dead.' "If that was the case she fooled some smart people. Salvador Dali, Allen Ginsberg, Truman Capote... they were all obsessed with her, in love with her. In 2007 people still talk about her. That's huge power."
