Back in the 1970s, Gerry and Sylvia Anderson created the syndicated sci-fi series Space:1999. Set some 25 years into the future, humans had established a research center on the moon and had been storing nuclear waste on the far side. After a massive explosion, the moon is ripped from Earth’s orbit and sent hurtling through space. The 311 men and women that are trapped on Moonbase Alpha encounter strange aliens out in space as they search for a new planet to colonize and call home.
Space: 1999 ran for two seasons and stars Martin Landau and Barbara Bain, a then-married couple who’d worked together on from Mission: Impossible. Barry Morse co-starred on the first season and season two saw the addition of Catherine Schell and Tony Anholt. Other castmembers include Nick Tate, Zienia Merton, and Anton Phillips.
The series never had a true series finale but a mini-finale was filmed in 1999 on a replica set and features Merton delivering a final message from Moonbase Alpha. There was talk around that time of reviving Space: 1999 as a series of movies (ala the Star Trek film franchise) but the project didn’t get off the ground.
