Lighting and shadows can age a person, but this photo plus >>224 and >>226 tell me that he's lost a lot of weight because I haven't seen those eyes that sunken and with dark circles since he was at the London Evening Standard Theatre Awards in early 2014, about a month after he finished filming ISTL and he was still gaunt from playing a drugged and boozed up Hank.
