described Superman as "the closest opportunity I've had to playing a classical role on film, the closest expression to something of mythical dimension." His co-star Margot Kidder said after his death with the Superman films, Reeve "knew he'd done something meaningful. He was very aware of that and very happy with that role." Reeve used his celebrity status for several philanthropic causes. Through the Make-A-Wish Foundation, he visited terminally ill children. He joined the board of directors for the worldwide charity Save the Children. In 1979, he served as a track and field coach at the Special Olympics alongside O. J. Simpson.
