Space: 1999: Season One -- This Episode
Space: 1999 ("Avaruusasema Alfa" here in Finland) was the most lavish British science fiction TV show in the 70s, produced in between 1973 and 1976. Starring Martin Landau (later also an Academy Award winner) and Barbara Bain, both known from TV's original Mission: Impossible series, the show featured also such guest stars as Christopher Lee (known from countless horror movies and also Star Wars and Lord of the Rings franchises), Joan Collins (of Dynasty) and Ian McShane (of Lovejoy and Deadwood). The producer was Gerry Anderson with his wife at the time, Sylvia Anderson: the Andersons had already been responsible for the popular 60s sci-fi puppet shows such as Thunderbirds, Joe 90, Captain Scarlet and others. Space: 1999 was preceded by another sci-fi live action series, U.F.O. (1970).
Each Space: 1999 episode had in its opening credits a rapidly edited intro sequence of all key events. Now a fan called Trekkiedane has edited all the intro sequences of the series' Season One into one clip of 7:37, which you can see by clicking here.
