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.
A Question of Priorities
"A Question of Priorities" is the fifth episode aired of the first series of "UFO" - a 1970 British television science fiction series about an alien invasion of Earth. Tony Barwick wrote the screenplay and it was directed by David Lane. The episode was filmed between 28 July to 7 August, 1969 and aired on the ATV Midlands network on 14 October, 1970. Though shown as the fifth episode, it was actually the eighth to have been filmed.
