According to Reuters, the big budget, fourth installment in the 'Terminator' franchise, titled 'Terminator Salvation: The Future Begins,' began shooting on Monday in New Mexico, despite the risk that production may be shut down if the Screen Actors Guild decides to go on strike by July.

The movie, starring CHRISTIAN BALE, has an estimated budget of $150 million and is already scheduled to hit theaters in May of next year. But SAG and the major studios are currently deadlocked after three weeks of talks.
