In 1973 Rod Serling narrated the TV documentary “In Search of Ancient Astronauts” which was based on the book “Chariot of the Gods” by Erich von Daniken. This show and its follow up “In Search of Ancient Mysteries” in 1975 would serve as pilots for the popular TV series “In Search Of” (1976-1982). Serling was originally chosen to host the new show, but do to his untimely death had to be replaced with Leonard Nimoy. We will never know if “In Search Of” would have been as popular under Serling, but you can get an idea of what the show might have sounded like by watching “In Search of Ancient Astronauts”. Enjoy.
