Aussie actor Sam Worthington, currently starring in Avatar for James Cameron, has landed the role of Marcus, the star of McG's Terminator Salvation: The Future Begins.
Despite what you may have heard, John Connor is currently said not to be the central figure in the films - despite the casting of Christian Bale for that role. It's Marcus around whom the planned three-film story arc revolves, as a small group of survivors struggle to fight back against the machines.
The fact that Worthington is currently starring in a film for Cameron, the original Terminator and T2 director, has led some to conclude that Cameron has given his seal of approval to this film, after rather distancing himself from T3. But equally he might just have been recommending his latest leading man for a new job when McG phoned him in New Zealand, so who knows? We're sure he'd do as much for Bill Paxton.
