!!The Franchise
* WhatCouldHaveBeen: GeorgeLucas tried to get the rights to ''Flash Gordon'' to make his own movie. When blocked by [=Dino DeLaurentiis=], Lucas decided to [[StartMyOwn make his own]] [[Franchise/StarWars space adventure series]].

!!The film
* AmericansHateTingle: The movie didn't do great in the US, but it was a mega hit in Great Britain. So much so that it's considered a classic there.
* BeamMeUpScotty: Ming never actually says "Pathetic earthlings, who will save you now?" Except in the {{trailer|sAlwaysLie}}.
** Ming does say "Pathetic earthlings", a '''lot'''. (ie. "Pathetic earthlings, hurling yourself out into the void...")
* DoingItForTheArt: Playing Vultan was Creator/BrianBlessed's lifelong dream.
* PromotedFanboy: Creator/BrianBlessed has admitted in interviews that when he and his brother used to play a game based on the TV series he always wanted to be Vultan. Decades later he got to play the same childhood game on the big screen.
* StillbornFranchise: The actors signed up for a trilogy of films a la ''Franchise/StarWars'', and there was a spinoff children's TV show.
* ThrowItIn: Flash jumping into the camera screaming "YEAH!" was an improvisation by Sam Jones, as nobody could figure out how to end the movie.
* VindicatedByCable
* WhatCouldHaveBeen:
** The first draft of the script had, among other things, no Kala, Klytus being psychic, a Tiger Man aiding Flash, Ming having a group of Amazon warriors, and a proper swordfight between Flash and Ming.
** Directors considered for this film included Creator/FedericoFellini and [[Film/TheManWhoFellToEarth Nicholas Roeg]].
** All actors were signed for three movies, but problems with star Sam J. Jones during post-production (which led to SameLanguageDub) pretty much killed the trilogy.
