Land Of The Lost

Land of the Lost (1974–1976) was a children's television series created and produced by Sid and Marty Krofft. During its original run, it was broadcast on the NBC television network.

Land of the Lost details the adventures of a family of three (father Rick Marshall, son Will — around 18 yrs old — and younger daughter Holly-around 12 years old) who are trapped in an alien world inhabited by dinosaurs, chimpanzee-like cavemen called Pakuni, and aggressive, humanoid/lizard creatures called Sleestak that have a mix of insectoid and reptilian characteristics. The episode plots focus on the family's efforts to survive and find a way back to their own world, but the exploration of the exotic features of the Land of the Lost are also an ongoing part of the story.
