Aeon Flux, as played by Charlize Theron

The original caption to this photo, which we can't endorse, reads: "Any good superhero needs a great costume - and what better for the ladies than leather. Sienna Miller is set to make her action blockbuster debut starring as a butt-kicking raven-haired baroness, who opts for a tight fitting leather ensemble to fight the bad guys in the upcoming G.I. Joe: The Rise of Cobra." The problem, of course, is that this photo is actually of Charlize Theron as Aeon Flux in the 2005 film Aeon Flux. The G.I. Joe film wasn't released until 2009. We are sorry for the confusion.
