''Santa Claus Conquers the Martians'' (also titled ''Santa Claus Defeats the Aliens'') is a 1964 science fiction film (originally a children's book) in which Martians, trying to cure the malaise of their children, kidnap THE Santa Claus (and a couple of earth kids that got mixed up in the plot) and take him to Mars to create the first Martian Christmas. Santa takes the whole thing ''surprisingly'' well and is only too happy to help. However, a small band of Martians rebel against the idea of Christmas or children being happy and try to kill Santa Claus. By the end of the movie, the Martians discover that they can just get a really annoying Martian named Dropo to stuff a pillow down his shirt and DRESS as Santa, thus allowing Santa and the earth kids to go home.

A NoBudget kids film with cheap sets, awful costumes, cheesy acting, and a laughably bad script, the film regularly appears on lists of the worst films ever made. It is regularly featured in the "bottom 100" list on the Internet Movie Database, and was also featured in an episode of the Elvira hosted ''Movie Macabre'', the 1986 syndicated series ''Canned Film Festival'' and numerous other venues for bad movies over the years. It was directed by Nicholas Webster, and it stars John Call as Santa Claus. It also includes an 8-year-old Creator/PiaZadora playing the role of one of the Martian children.

It also had a comic book adaptation that was [[http://atopfourthwall.blogspot.com/2010/12/santa-claus-conquers-martians.html mocked on Atop The Fourth Wall]].

* AirVentPassageway: Santa escapes being ThrownOutTheAirlock this way. Given that this ''is'' SantaClaus, shimmying through vents should be a given.
* AliensStealCable: The alien children learn about Santa Claus through the reception of Earth [[strike:TV shows]] programs.
* AnnoyingYoungerSibling: Betty Foster
* ArchEnemy: Voldar
* BadassSanta: Santa doesn't ever fight anyone, but it should be noted how easily he shrugs and laughs at the ''numerous attempts on his life.''
* CaptainErsatz: [[http://en.wikipedia.org/wiki/Wernher_von_Braun Wernher von "Green".]]
* ChristmasElves: Unfortunately, they don't stand a chance against the Martians' [[http://www.retroland.com/air-blaster-gun/ Whamo Air Blasters]].
* {{Comic book adaptation}}: Dell published it as part of their "Movie Classics" line in the 1960s!
* CoversAlwaysLie: The film is called ''Santa Claus '''Conquers''' The Martians''. There's not really a lot of "conquering" going on, although it's probably meant in terms of hearts and minds.
* EnclosedSpace: The air lock where Santa Claus and the earth kids were trapped.
* EvilIsHammy: Voldar really chews the scenery.
* FoodPills: The Martian cuisine of choice
* TheFool: Dropo
* {{Foreshadowing}}: [[spoiler:Dropo is warned that he might be left on Earth in place of Santa Claus. The film concludes with Dropo being Mars' Santa.]]
* TheGrinch: Voldar
* HenpeckedHusband: Implied. When Mrs. Claus is frozen by Martian Wham-O Airblasters, Santa remarks that he can't remember the last time she was that quiet ''that long.''
* HermitGuru: Chochem, the Troll doll.
* {{Jerkass}}: Voldar
* KillerRobot: Torg (an anagram of "Gort", the killer robot from ''Film/TheDayTheEarthStoodStill1951'').
* LaughingMad: Although John Call as Santa is generally an unassuming, pleasant fellow, his laughter sounds more like a man undergoing a frenzied psychotic breakdown than a jolly old elf.
* LuddWasRight: Hinted at after the toy-making machine is sabotaged.
* UsefulNotes/{{Mars}}: Evidently.
* MechanisticAlienCulture: The Martians: [[FoodPills Food Pill-eating]], joyless, humorless humanoid creatures with metallic-green skin and distinctly robot-like headgear incorporated into their costume design; the dullness of their heavily mechanized lives results in their children getting addicted to joyful, cheery Earthling holiday television programming.
* MrsClaus: This is the first time she appears as a character in an audio-visual medium.
* MundaneFantastic: In a refreshing departure from many a ChristmasSpecial, Santa Claus is acknowledged as real and the army is dispatched when he gets kidnapped.
* NeutralFemale: Momar
* NiceHat: The hats that every Martian wears. The only one that doesn't wear one is Chochem.
* NoCelebritiesWereHarmed: Wernher [[PunnyName von Green]]
* NotHelpingYourCase: Kimar assures the kids they don't need to be afraid while ''sticking a rifle in their faces.'' No one seems to notice this.
* ObviouslyEvil: Voldar, ridiculously so.
* OffTheShelfFX: The Whammo air guns.
* PaperThinDisguise: After Droppo dresses as Santa, he's mistaken by the bad guys for the real Santa, despite the fact that his helmet can clearly be seen as well as his green face.
* ThePollyanna: Santa.
* {{Planetville}}: Mars apparently consists of a house, a factory, and a cave.
* PluckyComicRelief: Dropo.
* {{Portmanteau}}: Kimar (king Martian), Momar (mom Martian), Bomar (boy Martian), Girmar (girl Martian) etc. Not sure if Dropo means anything. ([[ChildhoodBrainDamage Dropped on head?]])
* ProudWarriorRaceGuy: According to Voldar the Martians used to be like this. He's hoping killing the humans will be a move back to what he considers GoodOldWays.
* PunctuatedForEmphasis: '''"Torg! COME. Out. Of. The. Spaceship."'''
* ReasonableAuthorityFigure: Kimar
* RepeatToConfirm: The Martian crew, while flying to and from Earth: "Fire retrorockets five and six." "Retrorockets five and six. Fire."
* RobotAntennae: The robot has what appears to be an antenna atop its head. Of course, the Martians wear helmets with antennae on them, so this might just be a Martian aesthetic.
* ScreenToStageAdaptation: A [[http://www.mavericktheater.com/html/santa_conquers.html small theater]] in CA has adapted this to stage and performs it every holiday season. It is snarkerific. The tickets for every seat of the season typically sell out within a few weeks of going on sale and the competition grows every year since people who've gone once want to see it again the next year. Much of the humor comes from the improvisation that the actors produce, so it's worth seeing every year even if you've already seen it.
* ShoutOut The robot "Torg" was likely a reference to "Gort" from ''Film/TheDayTheEarthStoodStill1951'' except with much, much less budget or creativity.
** Voldar mentions being able to destroy a city with a blast of the Martian [[Film/RobotMonster Q-Ray]].
* SingleBiomePlanet: Justified, as it is, well, Mars.
* TheSlacker: Dropo
* SpellingSong: "You spell it S-A-N-T-A C-L-A-U-S, hooray for Santy Claus!"
* StockFootage: Used to show how "much" the armed forces are defending the Earth.
** Some of which appears to be ''from World War II''.
* StupidStatementDanceMix: This film inspired a lo-fi techno group called "The Laziest Men on Mars"; they named themselves & their [[http://www.youtube.com/watch?v=CM0vVcuqDi0 title track]] after what the "Chief" called Dropo. If you've never heard of them, they did the song that powered [[http://www.youtube.com/watch?v=tdPKI2E9kZg All Your Base]].
* ThatMakesMeFeelAngry: "I'm cold! I'm tired!"
* TinCanRobot: Torg. More accurately Cardboard Painted Silver Robot.
* {{Toys}}: Check – Santa makes ‘em on Mars.
* TrueMeaningOfChristmas: The movie's theme is teaching the Martians the meaning of Christmas: To have fun.
* TyopOnTheCover: "Custume Designer".
