Arnold not a lock for TERMINATOR SALVATION, McG says.

Mere days ago actor Terry Crews told MTV that Arnold Schwarzenegger would play some role in the upcoming Terminator Salvation. But now, director McG has terminated the fondest wishes of Arnold's fans by telling MTV that the bodybuilder/actor/politician isn't confirmed to be involved in the film at all.

"(He's not confirmed) yet," McG now tells MTV. "In fact, today is April 10th, I'm doing this interview on April 10th and we don't know if Schwarzenegger is in the movie or not; it's not clear. I can say that."

The director went on to suggest that some likeness of Schwarzenegger will appear in the film, whether Schwarzenegger himself plays a role or not.

"This film is largely about Skynet collecting human tissue in the interest of creating lifelike tissue for the T-800, which is the Schwarzenegger character," McG explained. "And if you think about it, we had to go through a lot of lab rats to get to the polio vaccine. Skynet has to go through a lot of human beings to get to that realistic T-800. Kyle Reese always talks about the T-600 being easy to recognize — a rubber skin, prosthetic look. We've got two T-600s in the film, but it's [about] the coming of the T-800, which represents lifelike human flesh being grown in order to get to that level of proficiency."
