While you may or may not agree with some of the costumes whipped up for the actors in the new G.I. Joe movie, which you can see in saucy hi-res here, you've got to admit that Sienna Miller's Baroness is pretty darned close. She's just slightly updated and really rocking the leather. (Although they really should have given her the classic black-rimmed glasses, rather than those less-cool, barely there frames.)

Now IESB has a few images of Sienna Miller on set, sporting a few distinct trails of blood on her face. There's something quite creepy, yet cool, about a raven-haired woman in black leather/pleather, carrying a gun, and smiling while blood trickles down her cheek and neck. But now I can't decide what I want more -- to see The Baroness fight in those wobbly shoes, or see a showdown between The Baroness and Selene, because they're definitely sporting a similar, gun-wielding look.

The film is currently in production, and we get to see what Stephen Sommers makes of the Hasbro line on August 7, 2009.
