DIED. Colleen Dewhurst, 67, raspy-voiced, Tony Award-winning actress; of cancer; in South Salem, N.Y. Although she appeared in a number of television and feature films, Dewhurst was most identified with the dramas of Eugene O'Neill on Broadway. She played the forlorn, drug-plagued Mary Tyrone in Long Day's Journey into Night and the murderous Christine Mannon in Mourning Becomes Electra. Dewhurst won a 1974 Tony as best dramatic actress for her performance as Josie Hogan in O'Neill's A Moon for the Misbegotten. Her last film appearance was in this year's Dying Young, which stars her son Campbell Scott, one of two children with actor George C. Scott, her former husband.
