An 1985 Sci-Fi film adapted from a Barry Longyear [[Literature/TheEnemyPapers novella]].

The humans and the aliens (Dracs) have been at war (in space) for some time now. There's a great deal of prejudice between them, and the humans think of the Dracs as "lizards" and some worse terms.

Then this one human, Willis Davidge (Creator/DennisQuaid), shoots down a Drac ship, and both ships crash-land on a dangerous planet. Davidge's co-pilot dies and he's left to fend for himself. Then, while trying to get revenge on the Drac, he ends up getting captured instead.

The Drac, whose name, Jeriba Shigan (Louis Gossett, Jr.), gets shortened to "Jerry" for the film, forces Davidge to slave away at building shelter and such, as he managed to hang onto his sidearm. But when the danger from deadly terrain, storms and predators gets to be too much, Jerry and Davidge end up working together, and then becoming friends.

Then Davidge decides to head out and see if there's any chance of them being rescued, but Jerry won't come with him. A good thing, possibly, as Davidge finds good news in the form of a futuristic [[ProductPlacement Pepsi can]] (evidence that humans have visited Fyrine IV) and bad news in the form of a Drac skull (evidence that the humans are illegal strip miners). Once Davidge gets back, he learns that Jerry is pregnant (turns out that Dracs can self-fertilize and have no control over the process). Sadly, something goes awry and Jerry dies in childbirth, so Davidge raises the kid, Zammis (ZAH-mees), by himself.

Either because the film studio thought that ViewersAreMorons or because [[PragmaticAdaptation films work better with a climax]], the [[HumansAreBastards villainous humans]] return to set up their mine run using Dracs as slaves. Since Davidge didn't teach Zammis that some humans are evil bastards, Zammis quizzically wanders into the area and gets captured. Davidge tries to save him but is shot dead by a [[LargeHam scenery-chewing]] slavedriver played by Brion James.

Or so it seems. Turns out his body is retrieved by a military scouter and brought back to the starbase where he once served. They're just about to give him a funeral (straight out the airlock) when he revives and starts mumbling in the Drac language while unconscious. His former comrades nurse him back to health, and he steals a ship and heads off to find Zammis.

In a final conflict with the evil miners, Davidge enlists the help of the Drac slaves, freeing them, taking out the overacting slavedriver and his cronies, and finding Zammis, who gets his CrowningMomentOfHeartwarming because it looked for a moment like he was dead but then he rouses and says his CatchPhrase from earlier, "Zammis get four, five?" (referring to how Dracs have only 3 digits on their hands while humans have 5).

Because Jerry taught Davidge his Drac lineage (something highly treasured in Drac culture), he is able to recite it to the elder council on Zammis' home world and formally introduce the young Drac to his own society. In honor of his actions, Willis Davidge's name is added to the Jeriba family line.

And for the record, not actually the TropeNamer for EnemyMine. The phrase predates the movie.
!!The novella and film provide examples of the following tropes:

* AllHailTheGreatGodMickey: Alien Jeriba Shigan assumes that Mickey Mouse is a great spiritual figure.
* BigBad: Stubbs, the leader of the Scavengers.
* BizarreAlienReproduction: The Drac are parthenogenic, which means they self-fertilize. Watching Davidge helping the rather masculine Jeriba have a baby is more then a little surreal.
* BlackDudeDiesFirst: The first casualty is Simpson, a black woman who's lead pilot of one of the fighters, when a Drac manages to get on her six and blast her to space dust. That Drac happens to be Jerry, and Davidge's attempted RoaringRampageOfRevenge is what kicks off the plot proper.
* ABoyAndHisX: An Earth soldier and his parthenogenic reptilian alien adopted child.
* ChekhovsGun: The Fyrene Pit Fiend appears almost immediately after the crash, and repeatedly menaces both Davidge and Jerry. The turtle-like groundrunner, the Pit Fiend's first victim, also comes in very handly both as food and as a meteor shield.
* ConvenientlyClosePlanet: Not only do they both crash on the nearby planet, but within walking distance of each others spacecraft.
* CrazyCulturalComparison: Early in the relationship, Davidge quotes, "If at first you don't succeed, try, try again." Jerry thinks he must have learned this from "great Drac teacher, Shizumaat." Davidge responds he learned it from [[Creator/{{Disney}} Mickey Mouse]], and Jerry assumes he was a "great Earthman teacher." They also have this with Shizumaat's book that has its own version of "do unto others" and when Davidge comments on hearing it before, Jerry replies of course, since it's universal truth.
* CurbStompBattle: The beginning fighter scene starts out as this but turns ugly when the Drac [[ZergRush ambush]] the Alert squadron. Also pretty much every time Davidge faces off against the slavemaster.
* DeathWorld: Fyrene IV. If the predators and extremely powerful electrical storms don't get you, the periodic ''meteor showers'' will probably do the job.
* DeathByChildbirth: How Jeriba dies.
* DeadpanSnarker: Jerry has quite a sarcastic streak at times. "Jerry, old buddy, where would you be without me?" [[RhetoricalQuestionBlunder "Back home."]]
* {{Disneyfication}}: The ending of the film is much more optimistic than the ultimately happy but rather more cynical ending of the original novella.
* DiesWideOpen: Joey, Davidge's co-pilot, fatally wounded in the collision with Jerry's ship.
* DoubleMeaningTitle: Caused by ExecutiveMeddling. "Enemy mine" is a phrase referring to "the enemy of my enemy is my friend." The climax of the film also features a mine full of enemies.
* EnemyMine: The two main characters must join up against the elements to survive, in spite of being enemies. It's not the TropeNamer, however. [[OlderThanTheyThink The movie was named for the phrase that named the trope]].%% Now let's leave this like this, because if we remove the incorrect information completely it'll just get added back in.
* EveryoneHasStandards: Davidge isn't too found of humans who slave Dracs, and is disgusted by the government who look the other way.
* EvilIsHammy: If Brion James's villainous performance were any more hammy, several major religions would have to forbid watching it.
* FamilyUnfriendlyDeath: Several of the slavers die short but very gruesome deaths like one being thrown by Davidge into an industrial grinder with a brief glimpse of his body being torn apart.
* FantasticRacism
* FireForgedFriends: Davidge and Jeriba ''have'' to cooperate if they expect to survive at all.
* FollowTheLeader / RecycledInSpace: The movella and the film are ''Film/HellInThePacific'' IN SPACE!
* TheGoldenRule: The aliens' holy book has a version of the quote. Davidge remarks that the [[Literature/TheBible Bible]] has a similar quote, and Jerry isn't surprised. "Truth is truth." It highlights how neither of them practiced this (being at war) until they were forced to as well.
* HonoraryUncle: Davidge. It loses "honorary" when his name is added to the line of Jeriba.
* HumansAreBastards: The Dracs tend to think so. They claim that the humans are actually the aggressors in the war. But the humans believe otherwise.
** This is more or less inevitable, since the common folk on both sides have little to go on but propaganda intended to make them more willing to support the war effort. The Drac, however, claim the region being fought over on the basis that they were there first, by a wide margin, and the humans are upstart interlopers. The brief narration at the start indicates the Dracs seem to have the truth on their side.
-->'''Davidge''': "A race of non-Human aliens called the Dracs were claiming squatters rights on some of the richest star systems in the Galaxy. Well, they weren't going to get it without a fight......"
* HumansAreUgly: So says Jerry, at any rate.
-->"You... ugly... head."
** However, Jerry saves Davidge's life because he states that the Pit Beast is even uglier.
** [[IronicEcho Zammis says]] Davidge looks "terrible" after he's rescued.
-->'''Davidge:''' ''(ManlyTears)'' Do I?
** Inverted prior to that. Zammis had been exclusively raised by Davidge, and grew up ashamed of himself for not looking "normal" like his uncle:
-->'''Zammis:''' ''*crying*'' "I wish I was not a Drac!"
-->'''Davidge:''' "Hey, hey... Now, as far as Dracs go, you are one good-lookin' kid!"
* HumanoidAliens: The Drac have certain fundamental differences from human biology (most notably their reproductive cycle), but they're still bipeds with two arms and a head on top that does the talking.
* IdiotBall: Davidge, at first. He hounds Jerry down and inflicts a fatal wound on his fighter with his blasters. What does Davidge do? Follow him right into the planet's atmosphere. ''When he sees Jerry ejecting'', he just powers straight ahead, right on into Jerry's now-abandoned craft, causing the crash that kicks off the story proper. He doesn't do much better on the planet at first...did he not have an inkling that maybe the Drac escape capsule and/or sidearm would have ''security features'' to them to incapacitate potential ambushers?
* MirroredConfrontationShot
* MoodWhiplash:
** Davidge, chasing after a groundrunner, falls headlong into a [[OhCrap familiar looking pit]], cussing a blue streak. Slapstick soon turns to horror, though, when the resident Pit Fiend's tongue appears and begins seeking him out...
** An even more drastic one: the meditative sunset scene with Jerry and Davidge is interrupted by another lethal meteorite storm; they barely make it back to shelter, and amidst the continuous roar of the impacts around them, they're almost immediately at each others' throats...
* MuggingTheMonster: Davidge attempts to sneak-attack both Jeriba (to steal his supplies) and the slavedriver (to rescue Zammis). To say the least, neither ends well.
* NarratorAllAlong: The narrator turns out to be the elder Drac in the slave camp.
* NicknamingTheEnemy: Dracs are called "lizards" by humans.
* OneGenderRace: There are no male Drac or female Drac, as each Drac is both male and female at the same time.
* PapaWolf: Never mess with Zammis, [[RoaringRampageOfRevenge ever]].
* ThePowerOfFriendship
* PronounTrouble: Jeriba is referred to as "it", rather than "he" or "she," because all Drac are hermaphrodites.
** Humans were calling Dracs "it" without knowing they were hermaphroditic, however, so it's more initially a case of FantasticRacism.
* ReptilesAreAbhorrent: Subverted -- the Drac are loathed by humanity and personally by Davidge in the beginning, but Davidge becomes friends with Jerry, and ultimately raises his child.
* ShoutOutToShakespeare: "[[Theatre/{{Macbeth}} Double, double, toil and trouble!]] For my little brother!"
* SuperPersistentPredator: Taken to an extreme by the Fyrene Pit Fiend. Having its tongue blasted off and the inside of its mouth scorched wasn't apparently enough - it deliberately followed them to their camp to ''stage an ambush''. In an ironic twist, it also ''saves their lives'', forcing them out of the shelter just as a rock formation falls on it and crushes it - and the Pit Fiend.
* TrulySingleParent: The drac parental lineage is truly ''linear'', since they are self-fertilizing like some terrestrial reptiles. In the words of the novella, "Don't tell a drac to boff himself, because he probably will!"
* WarIsHell: Par for the course for a Creator/WolfgangPetersen film. It starts with the debris from a shot-up human fighter and the frozen body of the pilot, and gets worse from there. Highlighted by the atrocities that the human leaders conveniently ignore because they're at war.
