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.
Fox Mulder
Mulder made his first appearance in the first season pilot episode, broadcast in 1993. Mulder believes in extraterrestrial unidentified flying objects (UFOs) and a government conspiracy to hide or deny the truth of their existence. Mulder considers the X-Files and the truth behind the supposed conspiracy so important that he has made them the main focus of his life.
