Sienna Miller vamps it up as Edie Sedgwick, wealthy party girl muse to Andy Warhol back in the '60s. The cast is a bit all over the place (Guy Pearce, Hayden Christensen, Jimmy Fallon, Mena Suvari, Illeana Douglas, Don Novello), and the script is mightly flippant about time, place and biographical details. Plus, there isn't much to Sedgwick's life story. (Not to spoil it, but the girl didn't stick around very long). Still, Pearce has fun as a manipulative Warhol, and the film is of occasional prurient interest. 90 minutes R.
