History Film / BeneathThePlanetOfTheApes

* YouFailNuclearPhysicsForever: Okay, a cobalt bomb would be a pretty nasty weapon, in the [[SaltTheEarth "create lots of long-lasting fallout"]] sense. ''Not'', however, in the "turn the planet's whole atmosphere into a gigantic nitrous-oxide fireball that incinerates the whole surface" sense. Though the original intention was for it to be just an ordinary nuke that would just wipe out the two warring factions, but Charlton Heston suggested an expansion to EarthShatteringKaboom.

* DownerEnding: "''In one of the countless billions of galaxies in the universe, lies a medium-sized star, and one of its satellites, a [[InsignificantLittleBluePlanet green and insignificant planet,]] [[EarthShatteringKaboom is now dead.]]''"

* LatexPerfection: The mutants wear incredibly life-like masks to cover up the fact that their skin is so pale their veins are visible all over their body.'

* ScaryDogmaticAliens: General Ursus was meant to be an fairly obvious Hitler {{Expy}}, but by the finished film, he'd become a more generic GeneralRipper type with a lot of muddled Vietnam symbolism thrown in.

A fellow astronaut, Brent, is sent to find Taylor and rescue him... and somehow also falls in the Planet of the Apes. He first finds Taylor's girl Nova. After they discover a former New York subway station in a cave, he realizes where he is. The station leads to an Underground Lair inhabited by mutant humans with psychic powers, who have already imprisoned Taylor, and cultivate a "[[PointlessDoomsdayDevice Divine Bomb]]". When the apes decide to invade the ForbiddenZone and then find the mutants' lair... well, the trope examples below show it's catastrophic.

* CollapsingLair: the underground mutant lair.

* KillEmAll: Literally all.

* BigBadEnsemble: The Mutants and General Ursus

* KillEmAll

* DownerEnding: And how. Not only that, but we don't even get a cool shot of the Earth blowing up!

* KissOfDeath: In the second film, a mind-controlled Brent tries to suffocate Nova by forcefully kissing her.

* ANaziByAnyOtherName: Zaius again, but this time, General Ursus takes it even further complete with militaristic rhetoric.

* LatexPerfection: The mutants wear incredibly life-like masks to cover up the fact that their skin is so pale their veins are visible all over their body.

* ApeShallNeverKillApe: Ends up being TropeNamer three movies earlier than the most famous instance, although slightly different. When [[DoesThisRemindYouOfAnything pacifist apes stand in front of the gorilla army to stop them]], orders to shoot them down are replied with "I can't order them to do what the Lawgiver has forbidden. ''Ape shall not kill ape.''"

* TechnicalPacifist: The Mutants; they insist they are a peaceful people because they "only" defend themselves by using their PsychicPowers to either MindRape their victims to insanity/suicide or MindControl them into killing each other. Brent outright calls them hypocrites.

** For some amazing LyricalDissonance, the mutants' mantras are quite obviously Christian hymns with all references to "god" changed to "bomb".

** For some amazing LyricsDissonance, the mutants' mantras are quite obviously Christian carols with all references to "god" changed to "bomb".

* NubileSavage: Nova

* SayMyName: Nova's first (and only) word is "TAYLOR!"

A fellow astronaut, Brent, is sent to find Taylor and rescue him... and somehow also falls in the Planet of the Apes. He first finds Taylor's girl Nova, and with her discovers in a cave [[spoiler:a former New York subway station]], realizing where he is.

* ExecutiveMeddling: Charlton Heston didn't want the original film to succumb to {{Sequelitis}}, so he instead [[TorchTheFranchiseAndRun rewrote the ending to be the final destruction of the Earth]] (thus making any possibility of a sequel impossible). (Fox president Dick Zanuck was reluctant in accepting... until the board of executives gave him the pink slip[[note]]caused by years of costly bombs such as ''Film/DoctorDolittle'' and ''Film/HelloDolly''[[/note]] [[CreatorBreakdown and he asked the filmmakers to go ahead with it]]) .
** [[TimeTravel It didn't work]].

* HeyItsThatVoice: Creator/PaulFrees gives the InsignificantLittleBluePlanet speech at the end.

* TheOtherDarrin: Roddy [=McDowall=] wasn't available, so David Watson plays Cornelius this time out.
** [=McDowall=] still appears in the StockFootage from the first film that opens the film, though.

* PropRecycling: some sets were from ''HelloDolly!''.
