John Goodman has admitted he thought he had "kissed goodbye" to ever starring in a war movie at this stage in his career.
The 61-year-old actor plays one of the soldiers helping to recover art stolen by the Nazis during the Second World War in George Clooney's new comedy The Monuments Men, based on a true story.
John said of playing a soldier: "I'd just kissed it goodbye a long time ago. I never figured I'd be in a war movie.
"Everybody at the time wanted to serve the war effort and to be asked to put on a uniform to go to the front and try to save this art was a way of using your special talents to help the war effort. I'm very grateful to have been asked and it was so much fun to put on a uniform every day. Except for the boots, I had trouble with the boots.
"But it was like playing. It was like being 12 years old again, out in the yard."
George directed the film, which he stars in with John, Jean Dujardin, Matt Damon, Bill Murray and Bob Balaban. But John revealed in between takes George was able to joke around like one of the guys.
"We were part of a team," he said. "We all had great respect for each other, and once the cameras stopped rolling, once he finished his shots, then we would laugh, until the next set up. We just sat around telling jokes, swapping lines and just having the best time."
