Claudia Wells – 54

Claudia Wells had the opportunity to play the lead role in Back to the Future. She delivered an excellent performance, but actually declined the proposal of being cast in its sequels because she was going through a rough time with her mother’s battle against cancer. Her mother died from the terrible ailment and Claudia only returned to the screens about ten years later. Claudia Wells managed to stay on the straight and narrow, perhaps because of her devout Christian principles.
