Pretty face Sienna Miller is the first to join the cast of Stephen Sommers' "G.I. Joe," according to Variety.  In a description that is making fans twitchy, the mag calls Miller's character "the film's female lead, described as a raven-haired baroness and sexy femme fatale skilled in espionage."

Yeah.

Variety is also running the "Brussels-based" description for the Joes, despite Hasbro's recent insistence that the team would be geared towards the "All-American Hero" image from the early '80s, os it's possible that the person who wrote the article is going off old/incorrect information.  The Baroness should not be the female lead.  Scarlett and Lady Jaye should be the female leads.

Miller played Victoria in this summer's "Stardust" and co-starred with Hayden Christensen (and Guy Pearce) in "Factory Girl."
