Terminator Salvation director McG has been out doing the press rounds for his new Fox TV series, Human Target. Naturally, talk turned to his current slate of films, with the helmer confirming that he will indeed return for a fourth sequel in the robot franchise. He also spoke about the status of the currently in development reamke, 20,000 Leagues Under the Sea, and said that he really wants Sam Worthington in the lead role, after Will Smith dropped out of the project. Now, Worthington hasn't committed to the role, but he is apparently considering it if the project does take off. He'll next be seen in James Cameron's action opus Avatar, and then next summer's blockbuster in waiting, Clash of the Titans.
