* ActorAllusion: The character played by Sigourney Weaver was called Shipley in earlier drafts. She spends a lot of time in a capsule, is pretty badass and no-nonsense, and knows a lot about extraterrestrial life forms. Are we being told something?
* BannedInChina: It was released in China, but its 2D version was pulled from cinemas very quickly afterwards despite the film being the most popular shown in China ''ever''. It is likely a large part of this was its message, which could be seen as being potentially inspirational to oppressed people within China. Oddly enough, China still allowed the 3D version to be shown even afterwards.
* BasedOnADream: The Na'vi were partially inspired by a dream James Cameron's mother had about a tall blue woman.
* CashCowFranchise: It became the highest-grossing movie of all time. So along with the merchandise, [[MovieMultipack back-to-back-to-back sequels]] are scheduled, and Fox is milking as much from [[LimitedSpecialCollectorsUltimateEdition home video releases]] as they can.
* DyeingForYourArt: Creator/SigourneyWeaver dyed her hair red for the film.
* FanNickname
** For Quaritch: Colonel Bastard, Colonel Monster, [[ColonelBadAss Colonel Awesome]], Colonel [[ColonelKilgore Coffee]], Colonel [[Literature/HarryPotter Quidditch]], [[Franchise/{{Pokemon}} Lt. Surge]], the Q-Man.
** For the Na'vi hair-braid that links to everything: "Bio USB", "Ponytalia"
** The planet Pandora orbits is sometimes referred to as "Bluepiter," since it looks like... well, a blue Jupiter (made kind of obvious by its Great Blue Spot).
* FakeAmerican: Jake is American, but his actor Sam Worthington is Australian.
* HeyItsThatSound: The odd, barking "cough" sound made by the dire-horses is identical to the calling sound the raptors make in the first Film/JurassicPark film (watch in the kitchen, when the raptor calls for its buddy to look for Tim & Lex). Of course, they should sound the same: both are the cough of a male walrus or elephant seal. Some of the thanator's roars seem to be the same as those of the ''T. rex'', as well. Both films used the same SFX shop.
* HeyItsThatVoice:
** In the Japanese-dubbed version:
*** Jake [[Creator/HirokiTochi is]] [[Anime/MobileSuitGundam00 Lasse Aion]], [[Anime/MobileSuitGundamAGE Grodek Ainoa]] and [[{{Bokurano}} Kokopelli.]]
*** Parker Selfridge [[Creator/KeiichiNanba is]] [[VideoGame/FatalFury Andy Bogard]] and [[VideoGame/GuiltyGear Axl Lowe.]]
*** Neytiri [[Creator/YukaKomatsu is]] [[Anime/PantyAndStockingWithGarterbelt Scanty.]]
*** Colonel Quaritch [[Creator/TakayukiSugo is]] [[Manga/{{Naruto}} Hashirama Senju]].
* HeyItsThatGuy:
** Frank Jr. from ''{{Friends}}''.
** Fisher from ''Series/{{Bones}}''.
*** His role in ''Series/{{Bones}}'' is also used in a later episode when he and two other characters want to go watch ''Avatar'' in a cinema.
** The Persian ambassador/ Doctore from ''Film/ThreeHundred'' and ''Series/SpartacusBloodAndSand'' is the leader of the Horse Clan.
** Dr. Grace Augustine is played by Creator/SigourneyWeaver!
** Jake Sully is Marcus from ''Film/TerminatorSalvation'' Or, for some of us, Australian Theatre/{{Macbeth}}.
** Trudy is Ana Lucia from ''Series/{{Lost}}''.
** Neytiri is the blue-skinned version of Uhura from ''Film/StarTrek''.
** Colonel Quaritch is Freddy Lounds from ''Film/{{Manhunter}}''.
** [[Film/StreetFighter Sagat]] as the leader of the Omaticaya.
** Sturgis from ''Series/{{JAG}}''.
* KillerApp: For the BluRay format. It sold 1.5 million copies on release day, 6.2 million after three weeks. For quite a while, you couldn't walk into a Best Buy without seeing it all over the TV wall.
* TheOtherDarrin: According to DVDBonusContent, Cameron shot a short proof-of-concept scene as a "hey, look how awesome this is!" demo. In it, Jake is played by Daniel Bess ([[Series/{{Firefly}} Heroic-Sacrifice Mudder]], [[Series/TwentyFour Season 1 kidnapper-cum-love-interest]]) and Neytiri by [[Series/{{Lost}} Yunjin Kim]].
* TheRedStapler[=/=]{{Defictionalization}}: The Chinese [[http://www2.chinadaily.com.cn/life/2010-01/26/content_9375209.htm renamed one of their national park mountains as Avatar Hallelujah Mountain]] ''because'' of this film. Of course, according to [[WordOfGod James Cameron]], the design of the mountains in the film are inspired by the mountains around southern China. In particular, Huangshan.
* WhatCouldHaveBeen: James Cameron originally planned on filming ''Avatar'' immediately after finishing ''{{Titanic}}''. He soon found that the special effects technology of the time wouldn't be sufficient for portraying Pandora.
** ''Project 880'', James Cameron's original script ([[http://www.docstoc.com/docs/14294813/Avatar-Scriptment-by--James-Cameron here]]; [[http://chud.com/articles/articles/21969/1/PROJECT-880-THE-AVATAR-THAT-ALMOST-WAS/Page1.html summary here]]). Some items of note:
*** Earth and its environmental problems are explored. (Sully has never even ''seen'' a forest, so Grace has to practically hold his hand when they go into the woods.)
*** We see Josh (Jake) Sully's Avatar being born -- Sully actually "births" himself. Also, his reaction to walking again is quite different: it takes him a while to gain any sort of strength, and then [[ManlyTears he cries]].
*** It's revealed the Avatar program originally existed to train Na'vi to be an indigenous workforce for the Corporation, since it's so expensive to send human workers. Obviously, they didn't like that.
*** There is an Avatar controller who is burnt out because [[spoiler: his Avatar died with him in it. He committed Avatar suicide because he had fallen in love with]] a Na'vi girl who had been killed by the military.
*** The Avatars have a Na'vi guide named N'Deh [[spoiler:who is sleeping with Grace]].
*** Grace [[spoiler: survives the soul transfer]].
* WriteWhoYouKnow: Sigourney says she based her portrayal of Grace on James Cameron, in that she's a perfectionist JerkWithAHeartOfGold.

!! Similar Stories

* Since the movie employs basic tropes in a story plotted in a simple way, it is possible to imagine it to be a lot like other stories. It isn't really any more or less [[RecycledINSPACE "derivative"]] than anything else. This is the first movie on TVTropes that has sparked people to list so many ''different'' stories the movie reminds them of. A look at the list may reveal something about the themes and elements that stick out in people's minds:
** Handsome man (American/European) goes to a distant, exotic locale as part of the invasion force, falls in love with the native culture, and turns against his own to save them: ''Film/DancesWithWolves'', ''Disney/{{Pocahontas}}'', ''Disney/AtlantisTheLostEmpire'' and ''Film/TheLastSamurai'' RecycledInSpace That no one remembers ''A Man Called Horse'' (1970) and ''Film/LawrenceOfArabia'' tells you everything you need to know about this entry, possibly because not every 'person changing sides' story is automatically similar to Avatar despite what the {{hatedom}} claims.
** Transform the protagonist to resemble the invaded, non-human natives, add a deep mystic connection to their environment on a spiritual AND physical level, villains dead set on exploiting natural resources for financial gain, and an environmentalist message and we get ''FernGully''.
** ''{{Albion}}'' has a very similar plot, a planet with large 'network of energy' that connects all living beings, and even the natives of the planet look almost the same (only smaller and less blue), they even have a specialized organ that allows them to telepathically communicate with each other (a crystalline formation on their forehead). The game was released around the time Cameron first conceived the plot for this movie.
** A DeathWorld is the only place in the universe where one can find an extremely costly substance that's important for interstellar travel. An off-worlder shows up and finds a place among the natives, eventually leading them to victory over his people. Bonus points for him fitting their legend, riding a giant powerful animal. Double bonus for having an ecologist working for the bad guys but in essence one of the good guys, who also scoffs at the bad guys for their industrialist interest and missing the beauty of the planet itself. Anyone still question [[{{Dune}} Dune]] was an influence here?
** A disabled man goes to a distant land and meets some miners who are trying to mine precious minerals from underneath an ancient forest being guarded by intelligent native creatures. He also meets many of the forest-dwellers and becomes friends with them, especially a certain young woman. Then the miners and forest-dwellers get into an all-out war where many are killed while he tries to stop the war. Yep, it's ''PrincessMononoke''.
** DuelingMovies: By sheer accident or twist of fate, several movies have come out since production began on ''Avatar'' that are somewhat similar:
*** ''WesternAnimation/BattleForTerra'' has a similar plot and a similar look and feel, was an animated film ([[AnimationAgeGhetto though not necessarily for kids]]), and had a mediocre reception in general.
*** ''WesternAnimation/{{Planet 51}}'' also dealt with the "human as alien invader" story (as a comedy, of course).
*** ''WesternAnimation/{{Delgo}}'', another movie about two different sapient races coming to blows over... something, to the point where the creators of the former attempted to sue Cameron over the production of ''Avatar''.

* WhatCouldHaveBeen: ''Avatar'' was to have been designed by Creator/SteveRitchie; he pursued the license for that game. After his first layoff from Stern Pinball, Steve posted his design blueprint on his website.
