''The First Men in the Moon'' is the name of an Creator/HGWells novel about two Edwardian-era Englishmen who utilise some AppliedPhlebotinum to fly to the moon for a bit of a jolly gadabout. Things don't quite go as planned. There have been two filmed adaptions - one in 1964, directed by Nathan Juran, and more recently by Creator/MarkGatiss.

In the 1964 film, the United Nations has launched a rocket flight to the Moon. A multi-national group of astronauts in the UN spacecraft land on the Moon, believing themselves to be the first lunar explorers. They discover a Union Jack flag on the surface and a note naming Bedford and Cavor, claiming the Moon for Queen Victoria. This discovery drives the plot, as the UN and many journalists seek out these men to get them to recount their first mission to the moon in the 1800s. Only Bedford is still alive and tells the story.

The 2010 film sticks much more closely to the H. G. Wells original, with Professor Cavor and Bedford engaging in their flight to the moon alone. The ending is significantly changed.

Though not a full-on adaptation, the first volume of ''ComicBook/TheLeagueOfExtraordinaryGentlemen'' also features Professor Cavor as a major supporting character, and a struggle to possess the [[AppliedPhlebotinum Cavorite]] that fuels his spaceship ends up [[MacGuffin driving much of the plot]].

!!This novel provides examples of:

* AntiGravity: Cavorite blocks gravity. Put a sheet of it between yourself and the Earth and you're weightless -- or, rather, you're now in the weak gravitational grip of the Moon.
* BoldExplorer: When James Cavor discovers a material that blocks gravity, he quickly decides to set off and explore the moon.
* BrainMonster: The Grand Lunar is the ruler of the "Moonies," and rests in the throne room with his exposed brain taking up most of the cathedral-like ceiling space. There are lesser Moonies that hover around moistening this huge brain. The Grand Lunar is LawfulNeutral, but takes Doctor Cavor prisoner on the belief that humans are intelligent anarchists.
* CoolStarship: Cavor's polyhedral spaceship is not only the first spaceship; it's the first spaceship with '''curtains'''.
* DawnOfAnEra: [[AvertedTrope Averted.]] Cavor desperately wants the voyage to be this trope, but events conspire to prevent this.
* DilatingDoor: The Selenites' lunar iris is a physically huge example of one.
* FungusHumongous
* ForScience: Cavor's entire motivation.
* InsectoidAliens: The Selenites, each of whom fulfills a specific specialized role in lunar society.
* InsectGenderBender: the Grand Lunar and the common worker selenites are referred to as male despite being said to be similar to ants. Male ants are simply drones for procreation and usually die after fertilizing the queen.
* InterplanetaryVoyage
* {{Lightworlder}}: Well, the Selenites are from the moon, where the gravity is lower, after all...
* PublicDomainArtifact: Cavorite (often in lower case) has been adopted as a standard anti-gravity material in scores of sci-fi stories.
* SciFiWritersHaveNoSenseOfScale: Despite Cavor mentioning that the moon is 250,000 miles away, they make the journey in an unspecified, but nonetheless shorter space of time than it would take...
* SpeculativeFiction: well, it '''is''' H. G. Wells. Given how [[ScienceMarchesOn Science has marched on]], the speculative part is quite emphatic.
* StarfishAliens: The Selenites are a particularly strange breed - each is born to the life role they will have, the roles allocated by [[EldritchAbomination The Grand Lunar]]
* StarfishLanguage
* ThinkingTic: Cavor's tic of making odd noises while he's thinking is the whole reason he and Bedford even meet. Cavor has the habit of walking past the cottage Bedford lives in, while contemplating his experiments. He unconsciously sings as he walks, and the singing disturbs Bedford's attempts to write, to the point that he asks Cavor to either stop or to walk somewhere else.
* WeaksauceWeakness: The Selenites are pretty vulnerable to a punch to the head. It's like hitting cinder toffee, apparently...
* YourHeadAsplode: See WeaksauceWeakness above.

!!The 1964 adaptation provides examples of:

* DamselInDistress: Kate gets captured by the Selenites and held as some kind of scientific specimen when they find the sphere.
* HumansAreTheRealMonsters: Cavor's attempt to explain humanity to the Selenites comes across as this. They focus particularly on the contradiction of humans hating war and yet honoring people who fight in them.
* HumanityOnTrial: The Grand Lunar questioning Cavor about earthlings comes across as this; whether this was actually the Grand Lunars' intent however is left a little vague.
* JustEatGilligan: Cavor really should have shot both Arnold and Kate with the elephant gun as soon as she handed it to him. Kate almost gets the sphere tossed into the sun when she tries to look out the window, and Arnold does nothing but antagonize the Selenites from the moment they meet.
* ItsAllAboutMe: Bedford. He ropes his girlfriend into real estate fraud, immediately wants to use Cavorite for commercial purposes, and has no respect for Cavor's intentions of peaceful exploration.
* LightningGun: The Selenites have a large crystal-tipped cannon that can fire lightning bolts. They use it to kill a huge caterpillar-like monster.
* NiceJobBreakingItHero: The Movie. First, Kate almost dooms the expedition. Next, Arnold kills a bunch of the Selenites with little provocation. Finally, [[spoiler:Cavor infects the whole population of Selenites with his cold, killing them all]].
* [[OnlySaneMan Only Sane Woman]]: Despite her bouts of being TooDumbToLive, Kate was often the most honest and sensible of the three protagonists. First, for not being as duplicitous as her fiancé Arnold or as dangerously naïve as Cavor. Second, Kate sensibly helps repair the damaged ship in order for her and Arnold to escape.
* PantyShot: Since this is Victorian times, "panty shot" means seeing a pair of knee-length bloomers when the sphere lifts off.
* PoorCommunicationKills: This seems to be the case when Bedford overhears Cavor speaking with the Selenites' Grand Lunar. As the Grand Lunar openly states his concerns about how dangerous humans are from what Cavor has told him. Bedford assumes Cavor (and possibly humanity) is being [[HumanityOnTrial "put on trial"]] and starts shooting.
* SpaceSuitsAreSCUBAGear: Actually, just diving gear. The Edwardian equivalent, diving suits, are used as space suits.
* StrawmanNewsMedia: Vapid, celebrity-obsessed subtype. Once the first reporter attempts to interview a United Nations official, the message spreads and soon dozens of reporters are present.
* TatteredFlag: The modern astronauts discover, to their astonishment, an old, worn out Union Jack left in the Victorian age.

!!The 2010 adaptation provides examples of:

* AlternateHistory: It's just no-one believes Bedford.
* ArtisticLicensePhysics: [[spoiler: It's highly unlikely that a "gravity column" would flush a planet's atmosphere out into space...]]
* BrainInAJar: [[spoiler:The Grand Lunar's natural form seems to be this, only the "jar" is the inside of the moon itself.]]
* CassandraTruth: The 2010 film is set in 1969, just prior to the "first" official moon landing. Bedford's been to the moon, and has kinematographic evidence. No-one believes him, and his films are regarded as fakes.
* EasilyThwartedAlienInvasion: [[spoiler: The Selenites invasion gets stopped remarkably easily physically speaking. Cavor simply has to kill them all to do it...]]
* EldritchAbomination: The Grand Lunar [[spoiler: becomes one of these once introduced to the concept of empire and conquest by Cavor.]]
* FirstContact: It doesn't end well.
* {{Foreshadowing}}: Bedford's repeated use of the word "Imperial" as a suplerlative sets up [[spoiler:the Selenites' plan to invade and conquer Earth]].
* HeroicSacrifice: [[spoiler:Cavor destroys the moon's atmosphere to prevent an alien invasion, dying in the process.]]
* HumansAreBastards: Cavor is afraid that humanity will fight over the moon, as they do the rest of the Earth. [[spoiler: Ironically, his fear turns out to be justified, as the Selenites quickly adjust to the idea that being a bastard [[EvilFeelsGood might be fun]].]]
* MyGodWhatHaveIDone: [[spoiler:Cavor's reaction to teaching The Grand Lunar about conquest and empire.]]
* RubberBandHistory: At the beginning it looks like the science will be utterly outdated [[spoiler:only to reveal at the end that Professor Cavor used a sheet of Cavorite to flush all the oxygen off the moon in a HeroicSacrifice to save the Earth from a Selenite invasion, creating the deserted, airless moon discovered by Aldrin and Armstrong.]]
* ShoutOut: Bedford has a dream sequence that is almost exactly identical to the fantasy cinema of George Melies, creator of ''Film/ATripToTheMoon''.
* SteamPunk: It's a film about Victorian adventurer-scientists traveling to the moon and back. What would you expect?
* ViolenceReallyIsTheAnswer: [[spoiler: Although initially describing himself as a pacifist, Cavor ultimately decides that the Selenites cannot be dissuaded from their plans of violent invasion. The result? He decides to ''KillEmAll'' by using his Cavorite to ''blow away the Moon's atmosphere'', suffocating the entire species and rendering the planet utterly useless for all life forever afterwards.]]
