Before You Dive Into the Lost in Space Reboot, Check Out the Original Cast

Expedition commander and family patriarch John Robinson was played by Guy Williams, who also played the title role on the TV series Zorro. In the 1980s, he retired to Argentina, where he was quite popular from his days playing Zorro, and formed a circus with local fencing champion Fernando Lupiz.

The eldest Robinson child, Judy, was played by this Norwegian native who was adopted at a very young age by an American couple after her father was killed in World War II. Kristen is best known for Lost in Space, though she went on to have a lot of success doing TV commercials after the show was off the air.

The character of Dr. Smith is being played by Parker Posey in the reboot, but Harris originated this villainous role in the CBS series. He is probably best known for Lost in Space, but Harris also starred on the TV version of The Third Man for six years. In his later years, Harris did a lot of voice acting, including the films A Bug's Life and Toy Story 2.

Goddard played the pilot of the Lost in Space expedition, Major Don West, which is probably his best-known role. But after the CBS series was canceled, he went on to appear in numerous TV shows, including The Fugitive, The Mod Squad, and The Fall Guy.
