Sam Worthington on "Avatar 2"

In an interview with MTVnews Sam Worthington has revealed that James Cameron plans to shoot motion capture performances under water for Avatar 2 and that the director expects him to suit up and dive when cameras start rolling.  Worthington's a little hesitant about diving though, apparently not too thrilled with what he believes will be a "claustrophobic" experience.

He'd better get over his aversion to diving pretty soon though because Sigourney Weaver has hinted that filming on A2 will begin before 2012 is out.
