Switching from black-and-white to color for its second season, Lost in Space also abandons all pretense of being a serious space opera, opting instead for the camp approach popularized by the previous seasons big TV hit Batman. As a result, the Space Family Robinson (Guy Williams, June Lockhart, Marta Kristen, Bill Mumy, and Angela Cartwright), their pilot Don West (Mark Goddard), duplicitous and cowardly stowaway Dr. Zachary Smith (Jonathan Harris), and the steadfast Robot are visited by a cornucopia of outrageous characters ranging from a clumsy magician (played by Grandpa Munster himself, Al Lewis) to a misplaced Don Quixote type (Hans Conried) to a scurvy space pirate (Albert Salmi) -- complete with a robot parrot on his shoulder! In keeping with the general frivolity, Dr. Smith has become a much broader and more clownish figure, utterly divesting himself of the cold-blooded villainy he briefly displayed at the beginning of season one. Having spent all of the past season on a single planet, the travelers manage to get the Jupiter II in working order, blasting off into the void again -- only to be marooned on still another uncharted world! Of the 30 episodes telecast during season two, several stand out, among them The Golden Man, a well-intentioned if a bit heavy-handed lesson in tolerance and appearances are deceiving; and A Trip Through the Robot, wherein a miniaturized Will Robinson (Bill Mumy) and Dr. Smith embark upon a fantastic voyage to repair the robots damaged innards. ~ Hal Erickson, All Movie Guide
