Alexander Skarsgard & Brooklyn Decker: WonderCon Panel!

Alexander Skarsgard, Brooklyn Decker, and director Peter Berg appear on a panel for their film Battleship during WonderCon 2012 on Saturday (March 17) in Anaheim, Calif.

The 35-year-old actor is featured in a new behind-the-scenes look at the making of the soccer scenes from the film along with co-star Rihanna.

“It’s been a lot of fun, but I’m pretty sore. Chris, this guy from the Marine Corps, is a goalie. He’s been helping me a lot,” Alex said of learning the role of a soccer goalie. “It’s madness. I have no idea how it’s going to end up on screen, but I’m really enjoying it.”

“He’s actually doing really good for his first time ever learning to be a keep,” Chris said about Alex‘s abilities.

Battleship hits theaters in the U.S. on April 11!
