After bubbling on the cusp of stardom for several years, Sienna Miller may finally be poised to boil over into the mainstream with a host of new films, targeted at both arthouses and multiplexes. Those upcoming projects, skedded for a 2009 release, have earned her the kudo of ShoWest supporting actress of the year.
Representing the biggest departure for the actress, who first came to notice in 2004 cult Brit gangster pic “Layer Cake,” is her role in Stephen Sommers’ “G.I. Joe: The Rise of Cobra” as the rather extravagantly named Baroness Anastasia De Cobray.
The leather-clad, black-haired villain couldn’t be further from Miller’s past repertoire of bohemians, artists and indie-chic fashion plates. She seems inextricably tied to the 1960s, with roles as Andy Warhol muse Edie Sedgwick in “Factory Girl” and in the 2004 remake of ’66 counterculture classic “Alfie” as well as the upcoming “Hippie Hippie Shake,” in which she plays the wife of controversy-courting Oz magazine publisher Richard Neville, a fixture in the Swinging London scene.
The bombastic action and inherent cartoonishness of the G.I. Joe franchise would seem to be totally out of character with Miller’s previous roles, though perhaps that was the attraction.
“As far as ‘G.I. Joe,’ I wanted to do something where I wasn’t addicted to heroin, having a breakdown or dying at the end,” she told Film.com recently. “It’s a whole different world, a huge budget, a huge crew, with things blowing up around you all the time. I think initially I was just completely overwhelmed. …
“But once I kind of realized what I was doing, it was really fun to make a movie that was just pure entertainment, and a completely different style of acting, really performing in a different way. That variety is really exciting.”
