New York, January 29, 2007 – “She sings. She’s hilarious. She cooks! She made a roast chicken one night”, Jimmy Fallon said of his Factory Girl costar Sienna Miller at the premiere Monday night. “What does this girl not do?”, he added.

And then, there she was in a vintage beaded flapper dress: the bubbly, animated, energetic Sienna, who plays the tragic Warhol icon Edie Sedgwick. While she’s heard the criticisms, Miller is at peace with her portrayal. “Her [Sedgwick’s] brother saw it and said that he loves it. And her husband thought that it was like her. So I feel like if those people are happy, then I don’t mind so much”, she said.

Fallon calls Edie’s story heartbreaking, but Miller saw some brightness in the days when the “it” girl first arrived in Manhattan. “She was just so ready to go out and have fun, and she just wanted to live. That was really fun to do”, the British star said.

Fallon would have loved to have hung around Warhol’s factory back in the 1960s, but director George Hickenlooper said that his research on the film made him realize that it was a “very selfish era”.

Appropriately, they took the party over to the Chelsea Hotel’s Star Lounge, where Miller, Fallon, Guy Pearce and Mena Suvari hung out with fashion types, and the DJ inexplicably played 80's and 90's dance music.
