UFO (TV series)
A single season of 26 episodes (including the pilot) was filmed over the course of more than a year; a five-month production break was caused by the closure of MGM-British Studios in Borehamwood, where the show was initially made. Production then moved to Pinewood Studios in Buckinghamshire. "UFO" was first broadcast in the UK and Canada in 1970, and in US syndication over the next two years.
Doppelgänger (1969 film)
Despite the polarised critical reception and commercial failure of "Doppelgänger", Lew Grade offered the Andersons further opportunities to film in live action. Their first television series not based on puppetry was "UFO", which premièred in the UK in 1970. "Doppelgänger" is considered an immediate precursor to "UFO", and has also been described as a "trial run" for the Andersons' third live-action series, "". "UFO" featured actors, costumes, props, locations and music that had previously appeared in "Doppelgänger". Of the film's cast, Ed Bishop, Keith Alexander, Cy Grant, Martin King and Jeremy Wilkin had previously had an association with the Andersons: all had provided voices for "Captain Scarlet and the Mysterons" except Alexander, who had voiced characters for the penultimate Supermarionation series, "Joe 90". With 11 other cast members, all but Grant and King appeared in at least one episode of "UFO", in which Bishop had in the lead role of Commander Ed Straker.
