UFO (TV series)
Following poor ratings for "Joe 90" (1968–69) and the cancellation of children's espionage television series "The Secret Service" (1969) after only one series, Lew Grade approached Gerry Anderson to look into creating his first live-action TV series. Anderson worked with his wife, Sylvia, and producer Reg Hill to create a sci-fi adventure series based around UFOs. Anderson said the core idea for the series was that UFO sightings were a common issue during the late 1960s and that idea of aliens harvesting human organs came from the work of Christian Barnard and his pioneering transplant operations. The creative team initially envisioned an organisation called UFoeDO (Unidentified Foe Defence Organisation), which was to become the secret SHADO (Supreme Headquarters Alien Defence Organisation).

The complete series was released on DVD in the UK and in North America in 2002 and in Australia in 2007. 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.
