UFO (TV series)
The Andersons' live-action science fiction movie, "Doppelgänger" (also known as "Journey to the Far Side of the Sun") is considered an immediate precursor to "UFO", which was their first live-action TV series. The series featured actors, costumes, props, locations and music that had appeared in the film, and eleven cast members of the film appeared in at least one episode of "UFO".
