The final Irwin Allen sci-fi TV initiative of the 1960s, Land of the Giant (1968 - 1970) ran for two seasons and fifty-one hour-long episodes on ABC, and involved a group of desperate castaways trapped on a dangerous world of gigantic humanoids and other over-sized threats.
The passengers include the Dr. Smith-like trouble-maker, Alexander Fitzhugh (Kurt Kaszner), a young boy, Barry (Stefan Arngrim), the beautiful Valerie (Deanna Lund), and an impatient businessman, Mark Wilson (Don Matheson).
The mist-enshrouded jungle studio set, for example, is colossal, and more-than-convincing for its day.
Various episodes of the series saw the castaways either attempting to repair their ship and leave the dangerous planet, or effect change on the planet itself, which seemed to be ruled by a repressive totalitarian state.
I submit that Lost in Space, Time Tunnel and Land of the Giants all key off both the rampant techno-phobia of the decade while also hoping, contrarily, to tap the "Camelot"-styled optimism of the age as well. These two opposing impulses make Allen's series somewhat schizophrenic, but also damned interesting, at least in terms of analysis, or interpretation.
