!!The Book
* {{Anvilicious}}
* ArcFatigue: The movie wisely cut out the chapters involving the mining of the gold, or the long search for radiation.
* EndingFatigue: The book's climax is around page 320, and there's an obvious enough ending when the humans have retaken their planet. And then the book keeps going for 700 more pages.
* InferredHolocaust: Some of the Psychlo bases on other worlds were in the middle of occupied cities. When Jonnie checks on them a year or so after his attack on the Psychlo Empire, he finds blasted, lifeless ruins, [[MoralDissonance but thinks no more of it]].
* MartyStu: Jonnie is physically perfect despite hailing from a village plagued by radiation, an awesome fighter, a super genius, and so beloved by all that when he falls ill, the ''entire planet'', including countless tribes he has never met, is worried sick about him. Some of them '''add him to their pantheons'''.
** Heck -- his '''middle name''' is "Goodboy"! Lafayette, dontcha think you were trying a mite too hard to make this guy a God among men?
* {{Squick}}: The Bittie and Pattie relationship. If we're optimistic and they're both about the same age, we have two eight-year-olds who decide to get married someday. Then Bittie dies, and Pattie goes into a deep depression. And then years pass and Pattie still hasn't moved on, goes to Bittie's tomb, and demands that a parson marry them.

!!The Film
* AlternateCharacterInterpretation: The Psychlos are [[TooDumbToLive so stupid and childish]], it seems impossible they could have ''ever'' built their civilisation without destroying themselves with their petty infighting. It actually makes a ''lot'' more sense if [[WildMassGuessing one imagines]] that Psychlos were ''[[NotSoDifferent themselves]]'' a race of backwards slaves, whose masters invaded Earth 1000 years ago, but died out mysteriously during the interim, leaving behind all their technology for the Psychlos to abuse.
** Website/SFDebris commented that their use of gas-drones explains their military superiority: they can move in and destroy the local population without having a Psychlo brain screwing it up.
* BileFascination: The movie regularly places in the top (bottom?) 10 of most filmgoers' "worst movies of all time" lists.
* CrowningMusicOfAwesome: EliaCmiral's score is one of the few good things about the movie. A couple of examples: the aptly named [[http://youtu.be/4ym4VB0pvNY "Battlefield Earth Theme"]], which plays over the opening zoom-in to Earth and pan through the Rocky Mountains, and [[http://youtu.be/chPD4mC0V54 "The Dome"]], which underscores Jonnie's trip to the human processing center, shooting of the wrangler, and our introduction to Terl.
* HamAndCheese
* HarsherInHindsight: Some may find it hard to appreciate the heroes' methods after the real life tragedy that happened a year after this film was released.
* HilariousInHindsight: It's an unintentional ActorAllusion, but Creator/JohnTravolta goes around [[Series/WelcomeBackKotter with a rubber hose up his nose]].
** [[UsefulNotes/BarackObama "Yes! We! Can!"]]
** Travolta's "While you were still learning to spell your name!" line is funny if you look at his pronunciation of IdinaMenzel.
* HoYay: One of Jonny's followers spends much of the movie looking soulfully at his leader. Jonny even cuts off a lock of his hair for him, and he wraps it around his fist as a sort of talisman. There's arguably more chemistry between the two than between Jonny and his [[TokenRomance designated love interest]].
** The {{Podcast/Rifftrax}} guys had no trouble picking up on this subtext. Whenever the guy makes puppy dog eyes at Johnny, they start tearfully muttering "Love you!"
* IdiotPlot: Characters aren't making the wisest decisions in this film. Heck, the whole plot is kicked off, and Johnny's plan works, entirely because Terl is a greedy moron.
* MemeticMutation:
-->'''Johnny:''' A demon? A monster? '''A BEAST?! YAAAAAAAAAH!'''
-->'''Terl:''' While you were still learning how to '''''spell your name''''', ''I'' was being trained '''''to conquer galaxies!'''''
-->'''Zete:''' With endless options for renewal! (With endless options for renewal!) (With endless options for renewal!)
* MostAnnoyingSound: [[http://www.youtube.com/watch?v=rw8RVcUyma0 Every single time]] Terl and Ker laughs. For most of the time, it sounds like they're crackling rather than laughing.
* {{Narm}}: [[Narm/BattlefieldEarth Has its own examples]], unsurprisingly.
* NauseaFuel: Given the amount of tilted camera shots, it's probably a good idea to avoid this movie if you suffer from motion sickness.
** The entire film seems Hellbent on making the viewers as queasy and [[FetishRetardant uncomfortable]] as humanly possible. From the dirty, grimy actors and environments, to the physically repulsive Psychlos (of both sexes) and ridiculous costume design. Not to mention the overly-harsh filters, making everything too blue, or too green, or whatever. [[TheyPlottedAPerfectlyGoodWaste This may have been the point]], but that's little consolation.
* SnarkBait: Roger Ebert wasn't kidding when he said this would be the punchline for jokes about bad movies for decades to come.
* SoBadItsGood: A lot of people called it the greatest unintentionally hilarious sci-fi movie ever made.
* SpecialEffectFailure: The movie has a few scenes that fall under this trope. But the most infamous example would be when Terl demonstrates his weapon to his human workers by shooting the leg off a cow. It's clear that when Terl does this it's just a leg being pulled off a model cow by an invisible string.
** Chirk's OverlyLongTongue is a painfully obvious CGI model, too.
** Not to mention one DeletedScene where that guy [[DisneyVillainDeath gets thrown by Terl into a chasm]]; a brutally obvious green-screen work.
** Some of the costumes are ridiculous, probably RubberForeheadAliens at its very worst.
* SpringtimeForHitler: It's never really been confirmed if the movie was intended to flop, but the accounting to come up with the budget for ''Battlefield Earth'' was... creative at best.
* TookTheBadFilmSeriously: Creator/JohnTravolta. Subverted in that he was too confident in the film that he was either trying too hard or not really trying.
** Just about everyone plays it straight. Even the Psychlos, who come from a WorldOfHam, seem to be taking their ham very seriously. Only Creator/ForestWhitaker seems to be having fun with his role, and he stated that the only reason he did the role was MoneyDearBoy, and even later [[CreatorBacklash came to]] [[OldShame regret that]].
* VanityProject: To quote the other wiki: "Travolta, a long-time Scientologist, had sought for many years to make [[TheFilmOfTheBook a film of the novel]] by Hubbard, the founder of Scientology. He was unable to obtain funding from any major studio due to concerns about the film's script, prospects, and connections with Scientology, leaving the film in DevelopmentHell. The project was eventually taken on in 1998 by an independent production company, Franchise Pictures, which specialized in rescuing stars' stalled pet projects. Travolta signed on as a co-producer and contributed millions of dollars of his own money to the production, which was largely funded by a German film distribution company."
* VisualEffectsOfAwesome: While the CGI is generally mediocre at best, the collapse of the Psychlo dome and the resulting destruction of much of Denver (which, unlike most of the film's other effects, was achieved with physical models) actually manages to be pretty spectacular.
* WhatAnIdiot: '''Terl'''.
** Also, Jonny, as halfway through the movie, he has Terl pinned to the ground and has an opportunity to shoot him and get freedom for the "Man-Animals."
*** '''You'd expect''': That he either DOES shoot him, or another Psychlo comes to Terl's rescue.
*** '''Instead''': Opting to TRUST Terl for some reason, he respectfully gives the gun to Terl, who turns it on him, and Jonny is recaptured. Creator/RogerEbert and WebVideo/TheNostalgiaCritic call out this particular WhatAnIdiot plot choice in their negative reviews of Battlefield Earth (Ebert did so on Ebert & Roeper At The Movies).
**** Johnny is no longer concerned solely about himself and his friends. He knows the destructive power of the Psychlos and the radiation in places where free humans live. He wants the Psychlos gone and his people freed. It's less idiocy and more TheNeedsOfTheMany.
