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.
Dark Skies
Dark Skies is an American UFO conspiracy theory–based sci-fi television series (1996–97). 18 episodes, and a two-hour pilot episode were broadcast as a part of the Thrillogy block on NBC. The success of "The X-Files" on Fox proved there was an audience for science fiction shows, resulting in NBC commissioning this proposed competitor following a pitch from producers Bryce Zabel and Brent Friedman. The series debuted September 21, 1996, on NBC, and was later rerun by the Sci-Fi Channel. Its tagline was "History as we know it is a lie."
