Sleestaks, Chaka, and Will Ferrell
Whether during its original airing or in reruns, Land of the Lost was a TV favorite for a generation of kids. Its plot featuring Ranger Rick Marshall and his kids, Will and Holly, saw them trying to survive in a primitive, alien world populated by monsters, apemen, and the dreaded reptilian Sleestaks. Years after rumors of its production began, a July 17, 2009, release date has been announced for the Land of the Lost movie. The film will star Will Ferrell as Ranger Rick. Seriously.
