Lost in Space is a science fiction TV series created and produced by Irwin Allen, filmed by 20th Century Fox Television, and broadcast on CBS. The show ran for three seasons, with 83 episodes airing between September 15, 1965, and March 6, 1968. Their first TV season was filmed in black and white, but the rest of them were filmed in color. In 1998, a Lost in Space movie, based on the TV series, was released.

Though the TV series concept centered on the Robinson family, many storylines focused primarily on Dr. Zachary Smith ( Jonathan Harris ), originally an utterly evil would be killer who became a sympathetic anti hero by the end of the first season, providing comic relief to the TV show ( and causing most of the episodic conflict ).
