Christian Bale will work on three Terminator sequels, according to the franchise's production company.
The Dark Knight star is attached to play John Connor in Terminator Salvation: The Future Begins and is likely to star in two further spin-offs, says Victor Kubicek of Halcyon.
Talking to the BBC at the Cannes Film Festival, Kubicek said: "Christian was our first choice and he's a big fan of The Terminator, so we're very lucky.
"But with Batman he's already done the whole franchise thing, so we weren't sure he'd respond.
"He's really an actor's actor, so we're very proud," he added.
McG, helmer of both Charlie's Angels features, is to follow in the footsteps of James Cameron and Jonathan Mostow in directing the film - due for release on May 22nd 2009 - while Bale is attached to star as John Connor.
While the plot of the fourth film has been largely kept under wraps, it is believed it could be the start of a three-picture exploration of the human battle for survival after much of the Earth has been obliterated by Skynet - the computer that controlled the machines - in a nuclear holocaust.
However, Kubicek said: "We can't talk about the story points at all," and explained that the project was being approached with extreme security.
"Not everyone gets to see the script. They only see the part of the script that's relevant to the job they're doing."
As John Connor, Bale will lead the human resistance movement, while Australian actor Sam Worthington - currently shooting Cameron's Avatar - and rapper Common are also attached.
