Sienna Miller's High Anxiety – over Broadway

"I'm scared, obviously, but really excited," Miller, 27, tells Reuters about her upcoming American stage debut in playwright Patrick Marber's adaptation of August Strindberg's 1888 After Miss Julie, which she performed in London in 2003. The drama deals with class and sex, and is set in Britain right after WWII.
"If you want to be an actress, you think about opening on Broadway," said Miller, as well known for her adventures off-screen as on. This Friday she opens in the film version of The Mysteries of Pittsburgh, based on the Michael Chabon novel.
Her screen costar, Peter Sarsgaard, himself a stage vet, offered Miller a solid suggestion on how to keep up with a schedule of eight performances a week: hire a masseuse.
"That's good advice, I will have to take that on board," Miller said, laughing – and also admitting that in London, she employed reflexology to help her cope.
Miller won't be the only big name to help light up Times Square. This season on Broadway, the star attractions already include Jane Fonda, Susan Sarandon, Geoffrey Rush, Jeremy Irons, Joan Allen, James Gandolfini, Jeff Daniels and Marcia Gay Harden. Jeremy Piven was also on the boards – but he split.
