Land of the Giants is a one-hour American science fiction television series that aired on ABC for two seasons, beginning on September 22, 1968 and ending on March 22, 1970. The show was created and produced by Irwin Allen. Land of the Giants was Allen's fourth science-fiction TV series. The show was and released by 20th Century Fox Television. The series was filmed entirely in color and ran for 51 episodes. The show starred Gary Conway and special guest star Kurt Kasznar. Five novels based on the television series, including three written by acclaimed science-fiction author Murray Leinster, were published in 1968 and 1969. Series overview Set in 1983 (at that time, 15 years in the future), the series tells the tale of the crew and passengers of a suborbital transport ship named Spindrift. In the pilot episode, the Spindrift is en route from Los Angeles to London, on an ultra-fast suborbital flight. Just beyond Earth's boundary with space, the Spindrift encounters a magnetic space storm, and is dragged through a space warp to a mysterious planet where everything is 12 times larger than on Earth, whose inhabitants the Earthlings nickname "the Giants". The Spindrift crash-lands, and the damage renders it inoperable. Very little is known about the home planet of the Giants. This is partially because the Spindrift crew very seldom leaves the area where their spaceship crashed in the opening episode. Only two other (unidentified) giant societies are ever seen, in the episodes "The Land of the Lost" and "The Secret City of Limbo". No name is ever established for the mysterious planet, but the inhabitants know of Earth, Venus, and Mars, referring to them by name in one episode. Exactly where the planet is located is also never made clear. In the episode "On a Clear Night You Can See Earth", Captain Steve Burton (Gary Conway) claims to have seen Earth through a set of infrared goggles invented by the giants, implying that the two planets are near enough to see one from the other. The only established method by which Earth people may reach the giants' planet is high-altitude flight, passing through what one giant calls a "dimension lock". Although various episodes establish that at least six other flights have landed on the planet, no episode confirms anyone ever returning to Earth. The first mention of other visitors from Earth was in episode two, "Ghost Town",
