Terminator Salvation: The Future Begins producer Moritz Borman told Empire Magazine that Arnold Schwarzenegger will not be in the fourth installment of the franchise, according to The Sun. The movie takes place before the famous fighting machine has been built.

"We're keeping the script under very tight security" Borman said, adding "And one of the reasons is that we have a huge twist at the end, which we're being careful not to reveal. Like with the last Terminator -- we kept that under tight wraps so not even the crew got the last six or seven pages. I can tell you this much -- this is the story everybody has been waiting for. Namely, we're in the future. The part of it where Arnold's character has not yet been built but is on the drawing board. And in the next two episodes we'll get to the point where time-travel is more in the foreground. It's the war against the machines, the start of Skynet taking over the world."

Borman hinted that Californian governor Schwarzenegger could be featured in two subsequent movies and commented 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."

Borman refused to be drawn on rumors that Christian Bale is set to play John Connor and added "Everyone is assuming there is a John Connor and a Terminator in the script. Connor is in there along with another figure, but who is that figure?"

Terminator Salvation: The Future Begins comes to theatres in the summer of 2009.
