The 'Game of Thrones' family is mourning the loss of actress Margaret John, who died Tuesday, February 2, at the age of 84. Her career in television and filmed spanned more than 50 years before she took on the role of Old Nan on in the new series. GOT creators David Benioff and D.B. Weiss had this to say about her: "We were deeply saddened to hear about Margaret's passing. She was a warm and wonderful person, and she was completely fantastic in her scenes with Isaac. We wish she could see them...but many people will, and they will love her. We will miss her terribly."
