How Matt Damon and George Clooney will look like in period drama "The Monuments Men" has been uncovered. The two male leads were recently spotted filming the movie at the Palais Am Festungsgraben in Berlin, Germany.

Damon who donned a military uniform kept his young look, while Clooney bundled up in a warm jacket and sported graying hair and mustache to look older. The "Up in the Air" actor completed his look with vintage eyeglasses.

Based on Robert M. Edsel's book "The Monuments Men: Allied Heroes, Nazi Thieves, and the Greatest Treasure Hunt in History", the film will follow a group of art experts chosen by the U.S. government to find artwork stolen by the Nazis during the World War II era.

Clooney will not only star and direct the drama but he will also serve as the writer and producer alongside Grant Heslov. It will be his first producing gig since his collaboration with Ben Affleck and Heslov in another historical film "Argo" which won Best Picture at the Oscars.

Moreover, the big screen project reunites Damon and Clooney after the two worked together in Steven Soderbergh's "Ocean's" series as well as Stephen Gaghan's political thriller "Syriana".
