Winner: Richard Armitage
2015 saw a wealth of fantastic guest appearances (Sam Elliott has never been more devilish, Margo Martindale never more conniving, B.D. Wong never more beguiling), but none were more fully arresting than Richard Armitage on Hannibal. Transforming himself — even through his physical movements — into the Red Dragon character was astonishing, terrifying, and without equal. Hannibal was a show that grew and matured with each new season, and for Armitage’s exceptional portrayal of Red Dragon to cap off the show’s run was a fitting, if bittersweet end.
