Yahoo! Movies today premiered the first teaser trailer for McG’s upcoming sci-fi action flick “Terminator Salvation,” and although it doesn’t reveal much of anything, it definitely let me wanting to see a whole lot more.

As you may know by now, the fourth installment in the popular series stars Christian Bale as John Connor, who struggles to prevent the machines from eliminating what is left of humanity. The flick also stars Anton Yelchin, Sam Worthington, Moon Bloodgood, Helena Bonham Carter and Bryce Dallas Howard.

As I said, don’t expect to see much in this 54-second clip. Whatever you do end up seeing though looks pretty awesome. “Terminator Salvation: The Future Begins” is scheduled for release May 22, 2009.
