 Writer David Benioff (qv) said in a BBC interview, "The first time  I saw [Edward Norton (I) (qv)] on set he pulled back his hair and  showed me his widows peak. In the book, Monty Brogan has a widows  peak, but I hadnt mentioned it in the script. But Edward so wanted  to be in character that he wore a prosthetic widows peak for the  entire shoot."
