Matt Damon got back into his retro gear on the set of Behind the Candelabra in LA yesterday. He filmed with costar Dan Aykroyd for Steven Soderbergh's upcoming Liberace biopic. Matt first debuted his new look, sporting a full blond wig and waxed chest, when he reported to set on Monday. Although Matt is focused on his latest project on the West Coast, he's also somewhat of a presence during the London Olympics. His voice can be heard as the narrator of the United Airlines and TD Ameritrade commercials playing on NBC throughout the Summer Games.
