Tom Hiddleston certainly looks every inch the part in this still, the first Sony Pictures Classics has released from I Saw the Light, Marc Abraham’s Hank Williams biopic. Singer/songwriter Rodney Crowell plays Williams’ dad Elonzo. More importantly, Crowell is also the film’s executive music producer and the person charged with transforming the Brit actor into an American legend. They were in the process of that when Hiddleston joined Crowell on stage last September at the Wheatland Music Festival to sing “Move It on Over” in a performance that augers well for a film that ought to have a lot of people seeing the light.
