Chris Virdon was the son of Alan Virdon and Sally Virdon, left behind in the 20th century when his father's spaceship disappeared.


  • Ron Harper later recalled, "There was a photograph Virdon carried around of his wife and son. The photo was actually of my wife, Sally Stark and the producer's son. But when we filmed "The Legacy", they had cast a blonde actress, Zina Bethune, as the mother. Sally had dark hair, and to reinforce the story's point, they had to reshoot the photograph with a blonde actress."[1]
