FILM: New Terminator Trilogy

If you weren't partial to Arnold Schwarzenegger's Terminator trilogy, have no fear Hollywood is already casting a new one. Calm down. It isn't a remake or a rehash of the old story lines. The new trilogy begins with the subtitle The Future Begins. Originally, buzz circulated about Christian Bale playing the lead character John Connor, the messiah of a post-apocalyptic world. Geeks everywhere were salivating about how bad ass Batman could make the cult classic. However, it turns out that Bale won't be the lead until the second film in the trilogy. The Future Begins will actually focus on a guy named Marcus, who was "put out of commission"--I'm thinking cryogenically frozen--before the nuclear holocaust occurs. Marcus awakens in this post-apocalyptic world 15 years before the feared future illustrated in the first Terminator happens. He'll most likely be integral in helping Connor stop it. Casting has not occurred yet, but whoever gets the gig has to sign on for 3 films and probably a lot of weigh training...so that leaves out funny guys like Justin Long and Shia Labeouf, or pretty boys like Orlando Bloom and Justin Chatwin. Who do you think would make a great addition to the cast? Should they pick a nobody or a star?
