Lost in Space is a science fiction television program created and produced by Irwin Allen, produced by 20th Century Fox Television, and broadcast on CBS. The show ran for three seasons, with 83 episodes airing between 1965 and March 6, 1968. The first season was shot with black and white film, the rest in color. In 1998, a film based on the series was released. The show focused primarily on Jonathan Harris as Dr. Zachary Smith, originally an utterly evil would-be killer who as the first season progressed became a cowardly character, providing comic relief to the show (and causing most of the problems).
