Sienna Miller may have not won the Rising Star Award at this years BAFTA Awards but that doesn’t mean she isn’t any good! Miller will be staring in G.I. Joe as The Baroness. Her character has long black hair, black rimmed glasses, and a black leather outfit, Baroness is a dark, sensual femme fatale whose beauty is matched only by her ruthlessness. Which sounds mighty good. She spoke to UK newspaper, The Sunday Mirror, about how she is preparing for such a role.

I’ve started taking boxing lessons, and I’ve also had to learn how to fire guns with live ammunition. I’m a baddie, running around kicking everyone while wearing tight, thigh-high boots… I’m getting muscles everywhere.”
