Kicking off the work week with a full day of filming, George Clooney and Matt- Damon arrived on the set of “The Monuments Men” in Hertfordshire, England this morning (June 3).

The “Ocean’s Eleven” costars both donned military garb and reported for duty amidst a sea of extras, chatting with each other in between takes.

Also starring John Goodman, Bill Murray, Cate Blanchett, Jean Dujardin, and Hugh Bonneville, “The Monuments Men” is slated for release next year.

Per the synopsis, “In a race against time, a crew of art historians and museum curators unite to recover renown works of art stolen by Nazis before Hitler destroys them.”
