UFO (TV series)

UFO is a British television science fiction series created by Gerry Anderson and Sylvia Anderson and produced by the Anderson's and Lew Grade's Century 21 Productions for Grade's ITC Entertainment company. The Andersons had previously made a number of very successful marionette-based children's science fiction series including Stingray, Thunderbirds, and Captain Scarlet. He had also made one live-action science fiction movie, Doppelgänger, also known as Journey to the Far Side of the Sun, and now felt ready to move into live-action television and aim at a more adult market.

UFO was the Anderson's first totally live-action TV series. Despite the assumption of many TV station executives, the series was not aimed at children, but deliberately sought an older audience, with many episodes featuring adult themes such as adultery, divorce, and drug use.

UFO first aired in the UK in 1970 and in US syndication over the next two years. In all, 26 episodes, including the pilot, were filmed over the course of more than a year, with a five-month production break caused by the ultimate closure of the MGM-British Studios in Borehamwood, where the show had been made.

An idiosyncrasy of the series is that the term "UFO" is pronounced as a word ("you-foh"), as suggested by the real-world originator of the term Edward J. Ruppelt, and not as the more common "you-eff-oh". This is particularly true of the lead character, Ed Straker. Technically speaking the series title should properly be pronounced "you-foh" as well. However, the "you-foh" pronunciation was not consistently applied and some supporting characters use the more traditional form.

In a sad coincidence, lead actors Ed Bishop and Michael Billington died in June 2005, within five days of each other.
