"G.I. Joe: The Rise of Cobra" is out on Friday. Lots of action. One of the highlights -- not the best mind you, but up there -- is when the Baroness (Sienna Miller) and Scarlett (Rachel Nichols) throw down for a bare-knuckle brawl. Well, it's not all bare-knuckle. I recall some flying feet. And chains. No hair-pulling though. This ain't no cat fight; these sisters are serious.

In the below video, Miller and Nichols talk about their little brawl. It's a shame such lovely ladies had to mess each other up, but it's worth it for the high-energy action. And head over to MTV.com to check out the rest of our "G.I. Joe: The Rise of Cobra" Rough Cut!
