A 1956 {{Science Fiction Film|s}}‎ written, produced and directed by Cy Roth; rivals ''Film/LostContinent'' and ''Film/StarTrekTheMotionPicture'' for sheer [[PacingProblems glaciality of pace]]. Only the ''Series/MysteryScienceTheater3000'' treatment could make this snail watchable. On the other hand, it has lots of [[MostWritersAreMale pretty ladies]]...

The plot (such as it is) follows a space expedition to the newly discovered 13th moon of Jupiter, where the astronauts are captured by a bevy of young women (the titular "fire maidens", so called only because of one scene at the climax) who turn out to be descendants of the fabled {{Atlantis}}, and who [[MarsNeedsWomen need breeding stock]] as well as protection from a mysterious creature lurking about.

!!This film provides examples of:
* AllPlanetsAreEarthLike: Even if they're as far away from the sun as Jupiter. And Jupiter itself didn't become a sun until [[Film/TwoThousandOneASpaceOdyssey 2010]].
* {{Atlantis}}: Well, ''New'' Atlantis, at any rate.
* CaptainObvious:
-->'''Prasus:''' Food and drink will provide the necessary sustenance!
* DamselInDistress: Hestia, during the final sacrifice (seeing that she ''was'' the sacrifice).
* DullSurprise: Duessa looks on as The Creature bears down on her.
* ExpospeakGag
-->'''Stanhope:''' Beautiful, gorgeous! A species of fauna that demands extensive research program.\\
'''Anderson:''' You mean different to all this [forest]?\\
'''Stanhope:''' My dear Anderson, 'fauna' -- or in this case, 'fauni' -- refers to the animals characteristic of the region.\\
'''Anderson:''' Who cares about animals?\\
'''Stanhope:''' Man (''and'' woman) has sometimes been refered to as an animal.\\
'''Anderson:''' Oh, you mean people... [light bulb] GIRLS! Hey, why didn't you say so before!
* {{Homage}}: Duessa is actually named after a villainess in ''TheFaerieQueene''. Who knew there was so much culture in this movie?
* HelloNurse: A secretary walks a long long catwalk (and we watch every minute of it) to come down and take a memo.
* {{Leitmotif}}: The Fire Maidens have Borodin's 'Polovtsian Dances'.
* LostWorld: New Atlantis.
* MrExposition: [[strike:Clarissa]] Prasus Explains It All.
** And what he doesn't tell us, Hestia does.
* NeutralFemale: All the Atlantean girls.
* PublicDomainSoundtrack: Most prominently featuring Borodin's "Polovtsian Dances" from the opera ''Prince Igor''. There's also a lot of ballet music.
** SoundtrackDissonance: Stirring, energetic music is often played during the exciting moments of the film. HINT: There are no exciting moments in this film.
* RecycledInSpace: ''Theatre/TheTempest'' [[AC: in space]], beating out ''Film/ForbiddenPlanet'' by quite a few years.
* RubberForeheadAliens: The Monster
** And he's ImmuneToBullets. But not Gas Grenades.
* SchizoTech: New Atlantis has all the trappings of ancient Greece, plus electricity.
* ScienceMarchesOn: This film predates the actual discovery of Jupiter's real 13th moon by a couple of decades. Dialog covers this by saying the moon is normally shrouded by "terrestrial fog". Of course, Jupiter has been found to have ''67'' moons.
* SpaceIsNoisy: Especially during the "dodging meteoroids" scene: "You know, I definitely hear a bowling alley."
-->'''[[Series/MysteryScienceTheater3000 Crow T. Robot]]''': There's traffic in space!
* StockFootage: Most of the footage of the spaceship is of a V2 rocket used for spaceships in many films.
* SubspaceAnsible: Not mentioned in the film itself, but there's no other way to transmit real-time updates from Jupiter to Earth.
* TakeOurWordForIt:
** When the astronauts first exit their spaceship on Jupiter's moon, they use "remote control" (read: they all look upward at their ship) to close the hatch.
** Used again later when one character finds a hidden door out of his cell.
* WhatMeasureIsANonHuman[=/=]WhatMeasureIsANonCute: The Creature.
