Deidre Hall says she is not finished with "Days of Our Lives." She told People.com on Friday she will remain on the NBC soap. She is 78. Her run began 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 pledge to keep playing Dr. Marlena Evans. Hall holds a rare distinction. She has been central to the show's engine for more than fifty years. No exit date is scheduled. She just keeps turning up.
