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.

Bonus features include a commentary by Gerry Anderson on the pilot episode "Identified", and an actor's commentary by Ed Bishop on the episode "Sub-Smash". There are also some deleted scenes and lots of stills and publicity artwork.
