Kathy Coleman vividly recalled that guest-star Brooke Bundy attempted to leave the set with her wardrobe, but she was caught and forced to return it.
Wesley Eure suggested guest-star Brooke Bundy for a role on his other show, Days of Our Lives (1965). Bundy was hesitant to appear on a soap opera, but she took the role, stayed for two years, and followed it up with a four-year stint on General Hospital (1963).
The Zarn's ship is located within the "mist marsh", where the Flying Dutchman will be found during the show's third season (also contained within the area will be the Cro-Magnon Malic and an isolated tribe of Sleestak).
While stout voice artist Marvin Miller provided the Zarn's voice on this series, Leonard Nimoy voiced the character on Land of the Lost (2009).
First of three episodes featuring The Zarn, a mystical, slender-bodied, light-suited alien creature who plays mind games with the Marshall family.
