Space: 1999 ran for two seasons from 1975 to 1977.
In the opening episode, set in the year 1999, nuclear waste stored on the Moon’s far side explodes, knocking the Moon out of orbit and sending it, as well as the 311 inhabitants of Moonbase Alpha, hurtling uncontrollably into space.
Space: 1999 was the last production by the partnership of Gerry and Sylvia Anderson and was the most expensive series produced for British television up to that time.
Lew Grade wanting a network sale in the USA was told that to get a network sale he must have known names for the leads, Martin Landau & Barbara Bain were chosen, and then started a war over their fees that kept increasing with Lew giving in each time knowing that the network sale depended on it.
However, it came to pass that he did not get the network sale and the series was eventually syndicated in the USA.
Another “name” put forward to get the network sale was designer Rudi Gernreich, who was a friend of Barbara Bain.
But the designs he came up with were unworkable so the main costumes were actually designed by Sylvia Anderson and the guest artists costumes by production designer Keith Wilson, But to try and get the network sale Rudi Gerneich kept his credit for the costumes.
