'The Lincoln Lawyer' was Trace Adkins' most high-profile role until he took one of the leads in 'The Virginian.' It doesn't look like the big man is slowing down, either. The singer is set to play a sheriff in 'A Country Christmas' and work alongside 'Grey's Anatomy' star Sarah Drew in 'Mom's Night Out.' Adkins got his TV start on an episode of 'Yes Dear' in 2004 and then did voice work for several episodes of 'King of the Hill.'
