About Lost in Space

The Robinsons set out on a planned five-year mission to locate a new planet, but their voyage never goes as scheduled. Their ship, the Jupiter II, is repeatedly complicated by the scheming stowaway Dr. Zachary Smith, whose interference creates new crises each episode. Parents Dr. John and Dr. Maureen Robinson try to keep the family together while Major Don West handles piloting duties and the children, Judy, Penny, and young Will, cope with strange worlds and unexpected hazards. A sturdy robot rides along, frequently insulted by Smith yet forming a special bond with Will. Episodes mix tense sci-fi situations with lighter comic moments, keeping the focus on family survival without spoiling long-term outcomes.

Created and produced by Irwin Allen and Anthony Wilson, Lost in Space premiered in 1965. The show used practical effects and set pieces typical of the era and featured Guy Williams, June Lockhart, Mark Goddard, Marta Kristen, and Angela Cartwright in leading roles.

The original run didn't secure major industry awards, though it attracted a steady audience and ongoing fan interest. Its reputation grew after cancellation, and the series' name recognition helped spur later revivals and reinterpretations rather than trophy room success.

The series left a clear mark on pop culture, largely through its iconic robot and memorable lines like "Danger, Will Robinson," which seeped into broader media. It inspired a 1998 feature film and a later Netflix reboot, and its imagery and character dynamics have been referenced or parodied across television, film, and merchandise for decades.

Contemporary ratings on this dataset list the show at 7.092/10 from 120 votes, reflecting enduring affection for its tone and cast. The series leans into themes of family responsibility, trust, scientific curiosity, and the mismatch between ideal plans and messy reality. Dr. Smith supplies recurring comic antagonism, while the robot and Will embody a tender, child-centered strand that kept viewers invested through strange and often silly scenarios.
