Glen Powell gave his all - and almost bared it all - while filming his latest action flick, The Running Man. "I had to abseil down eight stories of a building in freezing conditions half-naked and wearing a harness which cinched me," Powell, 37, said during a Friday, November 7, appearance on The Graham Norton Show. "Believe me, nothing looked good." While Powell was focused on his onscreen antics, there was more happening behind the scenes while shooting physically demanding scenes.
