Land of the Lost is a children's adventure television series created by David Gerrold and produced by Sid and Marty Krofft, who co-developed the series with Allan Foshko. It is a live-action show mixed with stop-motion animated dinosaurs, originally aired on Saturday mornings from 1974 to 1976, on the NBC television network. CBS used it as a summer replacement series from June 22 to December 28, 1985, and June 2 to September 5, 1987. It has since become a 1970s American cult classic. Krofft Productions remade the series in 1991, and adapted it into a feature film in 2009.
