David Harbour is undergoing a total physical transformation for his next major role. Harbour, 50, looked completely unrecognizable when photographed on the set of his upcoming true crime thriller, Evil Genius, on Monday, November 10. The actor traded his typical brown hair and manicured mustache for an unruly gray beard and hairstyle, wearing a light-blue short sleeved button down and overalls that appeared to be draped over a padded suit. In some photos, he could be seen donning a tan jacket and glasses.
