MTV has premiered a new extended clip from G.I. Joe: The Rise of Cobra during the MTV Movie Awards pre-show. This is a slightly extended version of the clip that was shown at ShoWest a few months back, plus some extra footage, which you can watch below.

It’s heroes vs. villains in the all-new, live-action adventure G.I. Joe: The Rise of Cobra, in theaters August 7, and we’re with four of the film’s stars — Sienna Miller, Marlon Wayans, Rachel Nichols and Channing Tatum — who are lucky to be in one piece after filming some of the movie’s more spectacular stunts!

“I think the craziest one I did, they strapped me to the front of a Humvee going about 60 miles per hour swerving through the streets of Prague, which is doubling for Paris,” says Channing, who plays Duke. “It was good, though — didn’t get hurt, thank God.”

Everyone had to get in tip-top shape for their roles, and Marlon, who plays Ripcord, says, “We all worked out really, really hard. … When you’re playing a Joe, you’ve got to be a Joe.”

“We did six weeks of fight training, so we did it the healthy way,” add Rachel and Sienna.
