!!The books:
* ExecutiveMeddling:
** ''Ender's Shadow'' was originally titled "Urchin". That title was re-included as that of the first chapter.
** An accidental example: Card intended for only ''Speaker For the Dead'' and ''Ender's Game'' to be written. His agent accidentally pitched them as "the Ender trilogy", and Card decided to use the opening to write ''Xenocide''.
* InspirationForTheWork: Orson Scott Card got the idea for ''Ender's Game'' as a kid, when he tried to theorize what the military of the future would use to train soldiers in space, thus imagining the Battle Room. That manifested into the original short story, but the full novel didn't emerge until he was trying to decide who would be the protagonist of ''Speaker for the Dead'', when his wife suggested it could be Ender.
* ScienceMarchesOn: Notably averted in the remarkably accurate descriptions of tablet-sized computers, the Internet and the blogosphere, in a book written before the creation of the World Wide Web. Although, as [[http://xkcd.com/635 xkcd points out]], it missed the mark on the blogosphere in terms of scale if nothing else.
* WhatCouldHaveBeen: The ''Shadow'' books were originally going to be written by different authors, each centering on a different member of Ender's friends.
* WordOfGod: In one interview on ''National Review'', Card says that he was inspired by Bruce Catton's histories of the UsefulNotes/AmericanCivilWar, and that part of the message was that war means sacrificing the innocence of young people for the Greater Good and that it is the duty of the old to make sure their civilization is worth it.

!!The film
* AllStarCast: Creator/HarrisonFord, Creator/BenKingsley, Creator/AbigailBreslin, and more.
* BoxOfficeBomb: The film was budgeted at $110 million not counting publicity, and it only made back $125 million worldwide. This is mainly due to an extremely poor marketing campaign that, in assuming that all audiences were familiar with the novel, not only made the story rather unclear, but suffered from [[UncertainAudience uncertainty about its target audience]], and the tight competition it faced from ''Film/ThorTheDarkWorld''. The backlash the film received from the LGBT community due to Card's less-than-favorable views on homosexuality and gay marriage did not help Lionsgate one bit, despite director Gavin Hood and co-star Creator/HarrisonFord stating repeatedly that they support gay rights.
* DawsonCasting: The Battle School students are all meant to be ten years old, but they're all played by actors who are very obviously in their teens.
* DevelopmentHell: The film was mired there for decades. Unusually, Card was partially involved in keeping it there, as he preferred having no film than having one with a poor script and a bad child actor in the main role.
** SavedFromDevelopmentHell: Finally released in October and November of 2013.
-->'''Card''': My favorite thing about the end of 2013: I will never again have to answer questions about when the ''Ender's Game'' movie will come out.
* EnforcedMethodActing: The film was shot in sequence with Ford keeping his distance from Butterfield and the other kids at first so that their being in awe of The Harrison Ford (as well as their physical growth) would work for rather than against the story.
* FakeAmerican: Asa Butterfield as Ender.
* HeyItsThatGuy:
** You'll recognize Asa Butterfield from ''Film/{{Hugo}}'' or ''Series/{{Merlin 2008}}''. Harrison Ford is one of his generation's most prolific, beloved icons, playing [[StarWars Han Solo]] and IndianaJones.
** [[spoiler:Mazer Rackham]] is played by Film/{{Gandhi}} / [[Film/IronMan3 The Mandarin]].
** [[Film/TrueGrit Mattie Ross]] is a long way from the wild west.
** [[Film/LittleMissSunshine Olive]] moved on after the Little Miss Sunshine Pageant.
** [[Series/GameOfThrones Xaro Xhoan Daxos]] plays Sergeant Drill instructor Dap.
* HeyItsThatVoice: In the Japanese dub:
** [[Creator/RyotaOhsaka Ender is]] [[Manga/AttackOnTitan Marco Bodt]] and [[Anime/ValvraveTheLiberator Haruto Tokishima]].
** Hyrum Craft is [[Manga/BlackLagoon Dutch]] and [[Anime/CowboyBebop Vincent Volanju]].
** [[Creator/{{Mugihito}} Mazer Rackham is]] [[Anime/NeonGenesisEvangelion Keel Lorentz]].
** [[Creator/RyokoShiraishi Valentine Wiggin is]] [[Manga/HayateTheCombatButler Hayate Ayasaki]], [[VideoGame/{{Tekken}} Asuka Kazama]] and [[VideoGame/SenranKagura Hikage]].
** [[Creator/AtsukoTanaka Theresa Wiggin is]] [[Franchise/GhostInTheShell Motoko Kusanagi]], [[Anime/QueensBlade Claudette]] and [[Manga/{{Naruto}} Konan]].
** [[Creator/SatomiSato Petra Arkanian is]] [[Manga/{{KON}} Ritsu Tainaka]], [[Manga/FairyTail Wendy Marvell]] and [[Anime/QueensBlade Laila]].
** [[Creator/MiyukiSawashiro Bean is]] [[VideoGame/BlazBlue Carl Clover]], [[Manga/RozenMaiden Shinku]] and [[Manga/HighschoolOfTheDead Saeko Busujima]].
** [[Creator/KoukiUchiyama Bonzo is]] [[Anime/MobileSuitGundamUnicorn Banarghe Links]], [[VideoGame/KingdomHearts Roxas]] and [[InfiniteStratos Ichika Orimura]].
** [[Creator/HoukoKuwashima Alai is]] [[Anime/MartianSuccessorNadesico Yurika Misumaru]], [[Anime/MobileSuitGundamSEED Fllay Allster, Natarle Badgiruel]] and [[Anime/MobileSuitGundamSEEDDestiny Stella Loussier]].
** Dink is [[Anime/{{Doraemon}} Gian's new voice]]
** [[Creator/KenjiNomura Sgt. Dap is]] [[VideoGame/BlazBlue Iron Tager]] and [[Manga/{{Bleach}} Yammy]].
** [[Creator/RyuzaburoOtomo Admiral Chamrajnagar is]] [[Manga/DragonBall Dabura]] and [[Anime/MobileSuitGundamAGE Lord Ezelcant]]
* PlayingWithCharacterType: Harrison Ford is known for playing heroic characters, among them [[Film/StarWars Han Solo]], a JerkWithAHeartOfGold that was likable. Ford's portrayal of Graff is just the opposite - a cold, calculating figure that isn't concerned for the safety of his cadets so much as he's concerned with overwhelming an alien race.
* RoleEndingMisdemeanor: Orson Scott Card's vocal cameo was removed from the final cut after threats to boycott the film followed anti-gay remarks he had made. Still didn't help its box office chances, though.
* StillbornFranchise: Plans were made for a sequel, but the underwhelming box office performance has left that in doubt. It doesn't help that the sequels are completely different in tone from ''Ender's Game'', being slower-paced, more philosophical, and eventually reaching ''[[Film/TwoThousandOneASpaceOdyssey 2001]]'' levels of oddity.
* WhatCouldHaveBeen: [[Film/ThePhantomMenace Jake Lloyd]] as Ender and Creator/DakotaFanning as Petra. And yes, Card knew of how hated Lloyd was and felt a better script would have done him justice.
** Wolfgang Peterson (''Film/DasBoot'', ''Film/InTheLineOfFire'', ''Film/AirForceOne'' and ''Film/ThePerfectStorm'') was initially going to direct this film
** In one draft, Colonel Graff and Mazer Rackham [[CompositeCharacter were the same character]].
** The twist of the book would have been known from the beginning in Card's draft.
** At one point during the film's production, effects studio Creator/DigitalDomain (''Film/{{Transformers}}'', ''Film/RealSteel'') were co-producers.
** Card suggested that the scenes for the POVSequel ''Ender's Shadow'' could be filmed at the same time as ''Ender's Game''. [[http://www.hypable.com/2013/11/07/enders-shadow-script-game-sequel/?utm_content=sidefeatured&utm_campaign=sidefeatured&utm_source=sidebar&utm_medium=banner While Gavin Hood wrote up a script for]] ''Shadow'', the budget limited them from filming both movies.
** TheFlamingLips wrote a EP that they suggested as a concept soundtrack for the producers. Only one of the songs made it onto the film (over the end credits).
