Deidre Hall says she is not finished with "Days of Our Lives." She told People.com on Friday she will keep her role on the NBC soap. She is 78. Her run started in 1976. She said the reason is straightforward. 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 commitment to keep playing Dr. Marlena Evans. Hall holds a rare distinction. She has been crucial to the show's engine for more than fifty years. No exit date is planned. She just keeps showing up for work.
