It was already pretty well known that Arnold Schwarzenegger would not be appearing in the next installment of the Terminator series, unless the filmmakers managed to get him to pop up in some silly cameo. Now, Empire Magazine has gotten Terminator Salvation: The Future Begins producer Moritz Borman to talk about exactly how, if at all, Schwarzenegger will figure into the new trilogy of films. "It's convenient that he [The Arnold Terminator] hasn't been built at this point of the story, as Arnold has more important things to do right now, but that doesn't mean he might not re-appear later in the trilogy," Borman says. He also claims that Schwarzenegger has been briefed about this project, stating that "He knows the material and is very supportive of what we're doing. There might even be hints of his character in this one."
That makes sense to me, but it does create some issues that will have to be solved in the future -- if Schwarzenegger suddenly becomes re-involved with the series five or six years from now, he'll be well into his 60s and won't look anything like his muscular self, so how will he factor in? Will he play some old Austrian scientist who creates the T800 line of Terminators and models them after his younger self? And how will the movies show us a T800 if that means showing us young Arnold? Actually, I think this wouldn't be a problem -- have you seen Terminator lately? The T800s in the future segments of that movie barely look like Arnold anyway. They look like Michael Myers, if anything, with big latex faces. Like Michael Biehn says, they were easy to spot as non-human.
