Arnold Schwarzenegger will not be returning for a cameo role in TERMINATOR 4, according to the film's scriptwriter. Michael Ferris, who co-wrote the project with John Brancato, has scotched rumours the California Governor was set to make a short appearance at the beginning of the movie. He says, "Terminator 3: RISE OF THE MACHINES kind of closed the book on Schwarzenegger, as did his gubernatorial career."
