Starring internationally renowned actors Martin Landau, Barbara Bain, Barry Morse and Catherine Schell, the British-made Space: 1999 was the only truly original space adventure of the mid-1970s. Sandwiched between the demise of the original Star Trek and the opening of the Stars Wars series on the big screen, Space: 1999 featured a richly-visualized world where space was terrifying and mysterious, where not all problems were solvable by technology and the space travelers were very human. From the science fiction show’s conception in 1973 to its cancellation in 1977, this reference work covers each of the 48 episodes in depth, including a full plot synopsis, writer, director, guest star credits, and critical commentary that examines both the episode and other shows that have used similar plotlines. The popularity of Space: 1999 memorabilia and its many fan clubs are fully discussed, along with the possibility of a future movie or reunion show that would tie up the loose ends caused by the show’s abrupt cancellation.
