This two-season series details the adventures of the three crew and four passengers of the sub-orbital spacecraft Spindrift. They are drawn through a space warp that crashes them onto a planet where everything is 12 times normal size. The castaways struggle to repair their damaged craft and somehow get back to Earth while being hunted by the totalitarian government that rule the planet.
Despite the inherent scientific impossibilities (something 12 times as large would weigh 144 times as much, making it impossible for the "giants" to move), Land of the Giants, the last of Irwin Allen's four 60's s.f. programs, was highly-budgeted (about $250,000 an episode: a record for the time), features some decent characterization, and is another of the 60's shows to feature a competent African-American in a leading role.
