 This short film is a sequel to the TV series  _"Space: 1999" (1975)_ (qv) and was produced specifically for a  special convention held in 1999 to mark the year the Moon left orbit  in the series. At the time, the film was shown with the  understanding that it would be shown only once (due to licensing  restrictions). However, in 2002 A&E announced it would include the  film in a DVD release of "Space: 1999" episodes. Although not  broadcast, the this short film is considered canonical with the  "Space: 1999" (1975) TV series.
