The duo continued filming their new movie, The Monuments Men, Thursday in Berlin where the stars managed to both work hard and have fun onset. The film tells the real-life story of a small group of American soldiers who ran around Europe during World War II trying to track down art looted by the Nazis (some of which had been hidden in mineshafts and other unlikely places).
Proudly showing off his growing mustache, Clooney gave Damon the thumbs up as his scene wrapped for the afternoon.
Earlier in the day, Damon exchanged his military uniform for business attire as he wore a green trench coat and tie while filming.
The new project brings the good friends together again. Previously, Clooney and Damon worked on the Oceans franchise as well as the Oscar-nominated film Syriana.
