The New Adventures of Flash Gordon, also known as The Adventures of Flash Gordon, is an animated television series.
 The series is actually called Flash Gordon but the expanded title is used in official records to distinguish it from previous versions.
 Filmation produced the series in 1979, partly as a reaction to the mammoth success of "Star Wars" in 1977.
 The series was a homage to the original Flash Gordon comic strip and featured most of the original characters, including Flash's girlfriend Dale Arden, and the scientist Hans Zarkov.
 The series is still regarded as one of the most faithful adaptations, and one of Filmation's finest overall efforts.
