Actress Helen Wagner, who starred on As the World Turns as Nancy Hughes, has passed away at the age of 91. Wagner, a National Academy of Television lifetime achievement award winner, also holds the Guinness world record for playing Nancy Hughes for 54 years — the longest time an actor has played the same character on television. Wagner died Saturday. “All of us at As the World Turns are deeply saddened by Helen’s passing,” ATWT‘s executive producer, Christopher Goutman, said in a statement. “She is loved by generations of fans and while we will miss her greatly, Helen will always remain the heart and soul of As the World Turns.”
