Jack Douglas was an early producer and host of travel and adventure films on television. Douglas felt that people would like to explore the world via the small rectangular eye in their living rooms.
Almost all the travel-adventure shows on television sprang from the original Douglas format, which started with the true-adventure series, "I Search for Adventures," spread through Golden Voyage, Kingdom of the Sea, Bold Journey and Seven League Boots.
Douglas also produced "Keyhole," which he once described as a "documatic" — a dramatized documentary. "Keyhole" covered diverse subjects like aspiring actors, female judo experts, skydivers in action, a handler of poisonous snakes and a tour of the French Riviera.
