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.
UFO Hunters
The concept for the show was tested in a segment of History Channel's 2006 UFO special entitled "Deep Sea UFOs", produced by Motion Picture Production Inc, which featured two of the final four cast members. "UFO Hunters" was not a direct spin-off from a 2005 History Channel special with the same title, but they did use images from the 2005 special to promote the premiere of the new series. The tagline of the show is: "Hoax or History?" The series should not be confused with a similarly themed and titled "UFO Hunters", a special that debuted the same day and time on the Sci-Fi Channel, (now SyFy), and created by the producers of "Ghost Hunters", but which only aired one episode.
