British actress Sienna Miller refused to go on a drastic diet while filming the movie FACTORY GIRL because she needed the energy to keep up with the grueling shooting schedule. The star plays Andy Warhol muse Edie Sedgwick in the movie and filmmakers wanted her to drop some weight so she more closely resembled her character. She tells American publication People, "Edie was skinnier than I was so (director George Hickenlooper) wanted me to (lose weight). "But I can't work that hard and not eat. He'd come and try to snatch bagels out of my hands!"
