->''In a thousand years, Gandahar was destroyed. A thousand years ago, Gandahar will be saved.''

''Gandahar'' (known as ''Light Years'' in English) is a 1988 animated film by the master of French arthouse animation, René Laloux, based on Jean-Pierre Andrevon's French ScienceFiction novel ''Les Hommes-machines contre Gandahar'' (The Machine-Men versus Gandahar).

In the distant future and on a distant planet, the people of Gandahar exist in peace and harmony with nature and each other. This blissful existence is interrupted when Gandahar is attacked by bizarre, man-machine enemies who capture civilians and take them through a portal encased in metal to be brainwashed. Queen Ambisextra and her loyal Council of Women choose Sylvain, a young warrior, to scout the cause of this. He travels the land in search of the cause with young beauty Airelle, eventually falling in love with her. Along the way, they meet mutants and the giant mutant brain Metamorphis.

The history of the movie is odd and star-studded. After the success of the equally bizarre ''Animation/FantasticPlanet'', Laloux spent years trying to get the Gandahar project off the ground. He didn't succeed until a North Korean animation studio unexpectedly offered to animate his movie on the cheap. Harvey Weinstein picked up rights for the American release and had Creator/IsaacAsimov (yes, ''the'' Isaac Asimov) write an English translation. Definitely not a cartoon for the kiddies, Gandahar has been released in the "Masters of Cinema" series without any Region 1 DVD to date.

!! ''Gandahar'' contains examples of:

* AdaptationExpansion: A minor one, but in the english dub of the film, Queen Ambisextra is stated to be Sylvain's mother.
* AlienSky: Sort of. There is no sun during daytime, while the night sky is decorated by Gandahar's three shining moons.
* AmazingTechnicolorPopulation: Lots of blue people.
* AnimalEyeSpy: The tiny [[{{Cyclops}} one-eyed]] mirror birds seem to serve as little organic security cameras.
* AuthorTract: Anvil dropped about why totalitarianism is bad.
* BaldWomen: Airelle stands out by virtue of ''having'' hair.
* BarbieDollAnatomy: Completely averted, although some scenes change it in the English dub; but even in the original, there's not ''that'' much to see.
* TheBeautifulElite: Gandahar is full of them.
* BeautyEqualsGoodness: Played with.
* BizarreAlienBiology: Seen all over in the mutant badlands.
* BodyHorror: The petrified gandaharians are being [[spoiler:transported to the future where they are being drained dry of life, leaving only their decayed bodies behind]].
* {{Bowdlerization}}: The English dub is hated by most fans for cutting out and editing more objectionable parts of the movie. However, René Laloux thought that the translation was done well and never minded any of the changes.
* BrainInAJar: The Metamorphis is an extremely large one, but the building it's in still looks similar to a jar.
* BrainMonster: The principal antagonist of the film is a giant brain, made by the people of the utopian city of Gandahar as a prototype organic computer. When the superbrain didn't work out as planned, it was dumped in the ocean and forgotten. Interestingly, when the heroes first encounter this giant brain, it seems docile, and even gives the heroes the tool for its own destruction.
* {{Cephalothorax}}: Maxum. No distinct head, but a face on the front of his torso.
* TheChosenOne: Sylvain.
* ConvenientComa: Basically, Metamorphis's "stasis" can be likened to it.
* DerangedAnimation
* DidTheyOrDidntThey: In both the original and the censored English dub. The original has a shot of Sylvain taking his shirt off and then later completely naked as he's snuggling up to Airelle (who's also completely naked) while she talks about how the circumstances have brought them together and she's fallen in love with him, but the English dub cuts this and simply goes to the next morning with him and her both walking around shirtless. Even in the original, this leaves some question of whether there's a SexyDiscretionShot in there or not, since their "bed" didn't have any sheets (and they'd need to snuggle up to each other to stay warm), Airelle didn't start out wearing very much, Sylvain's shirt had suffered some ClothingDamage, and the people of Gandahar in general seem to spend a lot of their time naked anyway. Nothing more is clarified about the nature of their relationship in either version.
* {{Fanservice}}: Some of the rather weird artsy French sort...
* FutureMeScaresMe: Metamorphis realizes the Metal Men come from his insane future self and orders Sylvain to kill him 1,000 years hence.
* InCaseYouForgotWhoWroteIt: Marketing for the English dub called it "Isaac Asimov's ''Light Years''" since he translated it, although certainly didn't write it.
* LadyLand: Society ruled by Queen Ambisextra and her Council of Women.
* MechaMooks: The Men of Metal.
* MindScrew
* MonsterIsAMommy: A huge reptilian beast [[spoiler:frees Sylvain and Airelle from the Metal Men's transport]]... and proceeds to fuss over them as if they were her hatchlings.
* {{Mutants}}
* NippleAndDimed: Averted in the original, hard. According to Laloux the North Korean animators had to be shown certain French magazines to draw all of the women, since law there restricts such resources harshly.
* ProphecyTwist: The third line of the riddle/prophecy at the top of the page is: ''And what can't be avoided will be.'' This can be read two ways. First, that "what can't be avoided will be [avoided]," such as [[spoiler:the total destruction of Gandahar]]. Second, that "what can't be avoided ''will be''," such as [[spoiler:Gandahar still being invaded, getting thoroughly kicked in the teeth in the process, and ''maybe'' the leadership of the Deformed getting killed off in the future]].
* SceneryPorn: Bizarre but beautiful alien worlds lovingly explored through the animation.
* ScrewDestiny: Metamorphis' plan for Sylvain involves this.
* TagLine: "The Light Years" in the original French title, which was taken for the American dub's title instead of Gandahar.
* TakenForGranite: The enemy's energy weapons petrifies the humans it hits.
* TimeTravel
* TimeTravelTenseTrouble: "In a thousand years, Gandahar was destroyed. A thousand years ago, Gandahar will be saved." ItMakesSenseInContext.
* WhatHappenedToTheMouse: We don't see most of [[spoiler: The Deformed]] escaping from the future. Maybe the leaders got killed off-screen, but we see some who were nearby that got away.
* YouNoTakeCandle: The mutants said everything in both the past and future tenses (example: "was will be" instead of "is"). The trope is played with because the mutants are trying to tell the main character that he's going to be doing some time traveling. In the English version, they are also terrified of the present, so they fall back on the prophecy and find solace in the past-future.
