Gordon-Levitt Talks Cobra Commander's Mask, Lisp

Joseph Gordon-Levitt It's been suspected, it's been rumored, and it's been wisely deduced. Now, it's official: Joseph Gordon-Levitt admits that he's playing Cobra Commander in the "G.I. Joe" movie.

"I've got a good mask," he grinned recently, confirming that he'll play the man who challenges Destro for top dog status in the C.O.B.R.A. organization.

Various sources have revealed that Gordon-Levitt's mysterious character begins as a close friend of Duke (Channing Tatum), and might even be a former Joe himself; "USA Today" reported recently that the actor is playing "multiple roles." But this much is certain: By the end of the flick, he'll be the same blue-clad baddie we all remember.

"Working on the set, it feels like being eight years old and playing with your imagination and action figures," said the 27-year-old star. "Except they're [human] tall, instead of [toy] tall."

Asked if he's been practicing his lisp, the actor grinned and replied: "I've got a good voice, man."

The former "3rd Rock from the Sun" child star also went out of his way to make sure fans see the line between his current flick "Stop-Loss," and the cartoonish carnage he's currently filming. "Regarding 'G.I. Joe', people say 'you're making two wars movies.' Wrong, wrong, wrong," he explained. "'Stop Loss' is about a realistic portrayal of what it's like to be a soldier today. 'G.I. Joe' is fun."

"It's like going to the circus or getting on a roller coaster," the future C.O.B.R.A. leader cautioned said of the film, due in theaters in August 2009. "It has nothing to do with reality at all."

What kind of Cobra Commander do you want JGL to become? Do you want the soft mask or the metal one? Should he keep the lisp?
