The face most closely associated with the Terminator franchise could pop up in Terminator Salvation... but it'll only be a brief glimpse, by the sound of things. Minor spoilers, below.
During an interview with political blogger Bill Bradley, California Governor Arnold Schwarzenegger said he might appear in the latest Terminator film — but only if he doesn't have to do anything:
I made it very clear that I don't have the time to do the movie. I said that I would be willing to be in the movie if they get the technology together, and so they are working on that right now.
In other words, they might use Arnie's image, via stills from the original Terminator movie, but he wouldn't come in and allow himself to be photographed digitally. Those images might be superimposed on another actor's body, such as that of bodybuilder Roland Kickinger. Arnie said this would be for a brief scene where someone comes face to face with a "future Terminator." He added:
I think it's cool to continue on with the franchise . . . in case I want to jump over again and get into the acting after I'm through here.
But I'm guessing if it was that simple — if they could just lift Arnie's face from the original film — they would have done it already. It's probably not that hard to get permission to use the Governator's likeness, after all. The hard part would have been getting Arnie to come in and spend a day being photographed or filmed, so they could put a new image of his face onto whatever body they have. And it sounds like that's definitely not going to happen. But maybe he'll be in Terminator 5, after his term is over? [L.A. Times]
