Screenwriter Michael Ferris isn’t about to dole out too many spoilers regarding his "Terminator 4" script, but he recently made one thing perfectly clear: Arnold Schwarzenegger is most definitely not part of the equation.
From Cinescape: " According to "Terminator 4" co-writer Michael Ferris, don’t expect to see Arnold Schwarzenegger in the upcoming "Terminator" film.
"Terminator 3" kind of closed the book on Schwarzenegger, as did his gubernatorial career," said Ferris in an interview with Entertainment Weekly.
Ferris also added that "You will learn about Skynet and what that postapocalyptic future is like."
