British actor Clive Mantle, best known stateside for playing Greatjon Umber on HBO's Game of Thrones, was brutally attacked by two men outside a hotel early Sunday morning in Newcastle, England. The incident occurred after the six-foot, five-inch actor asked fellow guests at a Travelodge to keep the noise down. The two rambunctious guests disagreed with Mantle and, rather than quieting down, decided instead to bite the actor's ear off.
