George Clooney and Matt Damon are back in uniform and fighting not for their country, but for art.

Starring, written, and directed by Clooney, "The Monuments Men" tells the true WWII story of a group of art historians and museum curators -- no elite soldiers here -- on a mission to rescue art stolen by Nazis. Clooney rounds up a team of art aficionados including Damon, John Goodman, Bill Murray, Jean Dujardin, Hugh Bonneville ("Downton Abbey"), and Bob Balaban ("Moonrise Kingdom") to get a quick Basic Training before heading into Germany to save some masterpieces.

The new trailer for the film, which also stars Cate Blanchett, suggests a lighthearted approach to the dramatic story, which was first brought to the screen by John Frankenheimer in 1964's "The Train." (Clooney claimed that "The Monuments Men" is a new, untold story, but we'll let that one slide.)

In the trailer Balaban asks, "So we get to shoot some Nazis?" to which Murray responds with eager head nodding. If anything, we're excited to see this unskilled gang in battle.

Check out the trailer below and get ready for the literal art of war to hit theaters December 18.
