Despite being a wholly inaccurate representation of Andy Warhol (Guy Pearce) and his muse Edie Sedgwick (Sienna Miller), for its first third Factory Girl is an effective biopic driven by wonderful performances, especially Miller. By the second third, George Hickenlooper's questionable direction proves to be utterly sub-par, and by the final last third, Hickenlooper reveals himself to be a hack using beautiful people to gloss over that fact (see: his endless focus on Miller's naked form). Those familiar with Sedgwick's tragic adult life, which began with a sudden rise to international fame via Warhol's movies and was marred by drug abuse and a bad habit of inspiring artists like Warhol and Bob Dylan to create great works but not love her in return, will find nothing here but superficialities. Worse, there's nothing to explain why Sedgwick mattered so much to those like Warhol and Dylan (known only as "the Musician" here, played by Hayden Christensen). Blame Hickenlooper, who has no idea what his movie is about or what he wants to say about the tangled lives of these icons.
