Sienna Miller
Sienna Miller showed off her acting chops in the indie flick Interview, holding her own as an American model/actress interviewed by a tough reporter played by Steve Buscemi. "They didn't say, 'Cut!' after a scene," Miller has said, "because half the crew was Dutch and 'cut' means something very rude. So they would yell, 'Halt!'" Look for the fun-loving blonde Brit to let her hair down at the ceremony.
