Deidre Hall says she is not done with "Days of Our Lives." She told People.com on Friday she will continue with the NBC soap. She is 78. Her run started in 1976. She said the reason is basic. She has one career goal she has not managed to hit. She did not say what that goal is. The Independent picked up her public vow to keep playing Dr. Marlena Evans. Hall holds a rare mark. She has been crucial to the show's engine for more than fifty years. No exit date is scheduled. She just keeps turning up.
