->''"A world inside the computer where man has never been. Never before now...\\\
Enter its world."''

''TRON'': Video game developer Kevin Flynn, trying to prove that a CorruptCorporateExecutive has stolen his videogame programs, is sucked into the digital world inside the computer, where anthropomorphic programs are consigned to fight for their lives in gladiatorial games. With the help of Tron, an independent security program, Flynn must try to destroy the evil Master Control Program from within, bringing liberty to the cyber realm, and find a way of returning himself to the real world.

Sounds simple enough, right?

Although computer-generated special effects had appeared in film as early as 1973, ''TRON'' (1982) marked the first time that computers were used to create something "real", rather than to just represent computer graphics (sort of "real", anyway, since the story takes place inside a computer). Ironically, a large portion of the special effects in ''TRON'' were actually hand-drawn; even the computer-generated objects and environments had to have their geometry entered by hand for every frame, since no practical method of automating the process existed at the time. In general, the light cycles, tanks, recognizers and the Solar Sail were CGI -- however the huge amount of processing time required versus how much was available at the time required that they be rendered in black and white and hand-colored later.

Despite its bold look and bolder ambitions, especially for [[Creator/{{Disney}} Walt Disney Productions]] which was sinking further into irrelevance at that time, ''TRON'' was a commercial disappointment (it didn't lose money, but wasn't the hit they had intended it to be). The proven box-office poison that the Disney name was for anything but outright kiddie stuff at the time, led to the creation of Creator/TouchstonePictures two years later.

To add insult to injury, [[UsefulNotes/AcademyAward the Academy of Motion Picture Arts and Sciences]] considered it "cheating" to have used computers to create the special effects, resulting in the film not getting nominated for Best Special Effects. ''TRON'''s failure put CGI development on the back burner for years; while a few later productions made use of CGI elements (''Film/YoungSherlockHolmes'', ''Film/FlightOfTheNavigator'' and, most notably, ''Film/TheLastStarfighter''), it would not be until 1989's ''Film/TheAbyss'', and later 1991's ''Film/Terminator2JudgmentDay'' and 1993's megahit ''Film/JurassicPark'', that computer-generated effects would become feasible in the eyes of Hollywood and the public. This development and the film's persistent [[CultClassic cult fandom]] would cause the film to be popularly [[VindicatedByHistory reevaluated]] as a bold experiment in computer visual effects. This was the only project in which legendary futurists Syd Mead and Moebius would collaborate (each working on different aspects of the cyberworld.)

''TRON'' appeared as a level in ''VideoGame/KingdomHeartsII'' (it was the game director's admitted first choice for the series, but he couldn't find a way to put it in the first game).

''TRON'' has spawned two ([[CanonDiscontinuity mutually exclusive]]) sequels, the 2003 video game ''VideoGame/TronTwoPointOh'' (in which Alan and Lora's son Jethro is transported into the cyber-world) and the continuity consisting of the film ''Film/TronLegacy'' and its tie-ins: (in order of publication) the graphic novel ''TRON: Betrayal'', the video game ''VideoGame/TronEvolution'', and the television series ''WesternAnimation/TronUprising''. In 2015, a new autorunner game called ''Tron: Run/r'' hit Steam Early Access. The full version launched in February 2016.

!!''TRON'' provides examples of:

* AdvancingWallOfDoom: Near the end of the movie, an energy wall slowly derezzes Sark's Carrier, and Flynn and Yori must escape it while being trapped onboard the carrier. Fortunately, Flynn shields them, so all that's left is a wire-frame carrier with a sole intact control panel. When Yori hops off the Carrier, it finally fades away.
* AIIsACrapshoot: Played straight with Master Control, who figures he can run things 800 to 1200 times better than any human; inverted with the free programs, who are being persecuted because they believe in the Users and want to continue serving them.
* AlternateUniverse: The digital world is a whole {{Cyberspace}} civilization.
* AluminumChristmasTrees: The laser lab, the computer facility, and the ridiculously large security door were not sets and props, but an actual location, Lawrence Livermore Labs. Unfortunately, all of it has long since been replaced.[[labelnote:*]]The hardware that replaced it can be seen as the USS ''Enterprise'''s warp core in ''Film/StarTrekIntoDarkness''.[[/labelnote]]
** Similarly, the room Flynn and company walk through that looks to be filled with large object resembling washing machines... those were also real. They were *hard drives*. That's what hard drives looked like in the 70's.
* AndroidsArePeopleToo: It never even seems to occur to Flynn to think of them otherwise. Though, it's [[spoiler:Ram dying]] that really cements it.
* AndYouThoughtItWasAGame: Ram informs Flynn that he'll be forced to play video games. Flynn laughs it off, saying he plays those better than anyone. Unfortunately, those games turn out to be serious, lethal business, as Flynn discovers [[spoiler:when his casual defeat of Crom leads to the latter's death (at Sark's hands, after Flynn refuses to take the killing shot)]].
-->'''Flynn:''' On the other side of the screen, they all look so easy!
* AndYouWereThere: The programs are all dead ringers for the people who wrote them: CLU for Flynn, Tron for Alan, Yori for Lora, Sark for Dillinger, Dumont for Gibbs... and, down at the level where you'd need freeze-frame to notice, Sark's henchman for Dillinger's PA and Ram for Alan's cubicle neighbor (''Flynn Lives'' in ''Film/TronLegacy'' gives his name as Roy). The MCP, a product of numerous man-hours by various people, has a geometric abstraction of a face, but [[spoiler:when it falls apart at the end, the original core program can be briefly seen, and it has Gibbs's face]].
* AnthropomorphicPersonification: Programs are humanoids in a cyber suit that resembles their creators.
* ArcadeSounds: Justifed for once. Music/{{Journey}} is also playing on the PA [[TheEighties for atmosphere]]. Journey actually did two songs for the soundtrack: "1990's Theme" and "Only Solutions".
* AttackItsWeakPoint: Alan (aka Alan-1) instructs Tron to hurl his disc at the critical juncture of the MCP to destroy it. However, until Flynn distracts it, the weak point is shielded from Tron's disc.
* AttackOfTheFiftyFootWhatever: [[spoiler:Sark becomes this when he is critically injured during the climax]].
* AttackReflector: Tron and other gladiator programs can use their discs to knock away an enemy's disc. Skilled programs can even reflect them right back at them.
* BelligerentSexualTension: In a mild sense between Flynn and Lora in the beginning despite the fact they've officially broken up.
* BenevolentAI: User-Believer Programs are happy to serve their human creators, taking great pride and contentment in their service. Ram even remarks about how much he liked working in insurance and helping people plan for the future.
* BigDamnHeroes: Flynn gets one at the end when [[spoiler:he jumps into the MCP's beam just in time to give TRON the opening he needed.]]
* BigNo
** Flynn screams this when Sark orders him to finish off Crom.
** And Tron has one when it seems Flynn and Ram have been killed.
** The Bit does a panicked "no no no no no no" when Flynn is about to crash his Recgonizer into a bridge that a Game Tank is currently crossing.
* BlackmailIsSuchAnUglyWord: Or "Embezzling" in this case when Flynn is accused of it.
* BlueIsHeroic: A Program's circuit colors and pattern indicate their allegiance and relative position in the system. Encom User-Believer Programs have circuitry of bright cyan.
* BoomHeadshot: During their battle in front of the MCP, Tron takes out Sark with a disk attack that splits Sark's disk... and his ''head''. We even get some [[LudicrousGibs gibs]].
* BrainUploading: WordOfGod says that programs' resemblance to their Users is not a result of this, but is simply a reflection of their personalities.
-->'''Gibbs:''' You can remove men like Alan and me from the system, but we helped create it. And our spirit remains in every program we designed for this computer.
* ChekhovsGun: The laser that digitizes an orange at the beginning of the movie establishes the means by which Flynn gets pulled into the computer system.
* ComicBookAdaptation: By Creator/MarvelComics, which was released around the time of ''Film/TronLegacy''.
* ConvenientColorChange: Users like Flynn can change their color scheme. Likewise, the Recognizers show the color of whoever is controlling them.
* CoolBike: And how. Check out the concept art of the light-cycles sometime.
** Overlap with WhatCouldHaveBeen: They ran out of polygons halfway through, which is why the front of the light-cycles is so much more detailed than the rear.
* CoolPlane: The Encom Helicopter, with real-life TronLines!
* CoolShip: Sark's Carrier is essentially a cyber Star Destroyer. It's cool even if we only see one side of it due to technology limitations.
* CoolTrain: The Solar Sailer Simulation moves on an elevated rail.
* CorruptCorporateExecutive. Edward Dillinger, who stole Flynn's programs, got promoted, then fired Flynn.
%% All Crowning Moments go on subpages, period.
* CreatingLifeIsUnforeseen: The Encom programmers have ''no'' idea that their software is breathing, sentient code that adores and worships them from afar.
* CrucifiedHeroShot: Sark tortures disobedient programs by "crucifying" them on a wall with electric impulses.
* CyberPunkIsTechno: The original ''TRON'' score was by electronic music pioneer Music/WendyCarlos.
* {{Cyberspace}}: TropeCodifier. Had at least as much influence on how fiction portrays it as ''Literature/{{Neuromancer}}'' -- and ''TRON'' was released [[OlderThanTheyThink two years before]] ''Neuromancer''. However, Creator/WilliamGibson introduced the idea of cyberspace in his short story "Burning Chrome"[[note]]The word "cyberspace" only occurs once in that story, as "Cyberspace Seven", the nickname for the Ono-Sendai VII deck. In the rest of the story, cyberspace is [[HilariousInHindsight ironically]] always called "Film/{{the matrix}}"[[/note]], which was published shortly before ''TRON'' was released, although after the film had been made. In fact, it was first published in an issue of ''Omni'' magazine that also had an article about the making of ''TRON''.
* DavidVersusGoliath
** TRON vs. Sark. Quite literally at the end when the MCP makes Sark tower over his opponent.
** Flynn vs. MCP with the MCP acting as a surrogate towards Flynn, the arcade owner, trying to rightfully get justice against the huge computer company ENCOM.
* DeadlyDisc: The identity discs, which all Programs use in the Game Grid. It derezzes most programs with one just hit, while Sark just collapses after Tron's disc grazes his helmet.
* DeadlyEuphemism: Programs don't "die"; they "derez" (short for "deresolution"). Averted whenever Sark or the MCP talk to or about Flynn, for obvious reasons. Also averted by Yori speaking about [[spoiler:Tron's supposed fate when Sark's Carrier rammed through the Solar Sailer]].
* DeadpanSnarker
** Bit, despite only being able to say "yes" and "no".
-->'''Flynn:''' (''while driving the recognizer'') Pretty good driving, huh?\\
(''[[DrivesLikeCrazy He crashes into several things]]'')\\
'''Bit:''' NO\\
'''Flynn:''' Who asked you?
** Kevin Flynn is a major snarker as well.
-->'''Flynn:''' I never should have written all those tank programs.\\\
'''Flynn:''' Now ''that'' is a ''big door''!
** Dumont gets in a good one, too. While being tortured by Sark.
-->'''Dumont:''' What do you want? I'm ''busy''!
* DeathGlare: Tron stares down the final Red warrior during his disc match, just before derezzing him.
* DeathTrap: Two versions
** GladiatorGames: The MCP orders that Flynn must play the games until he dies.
** ConveyorBeltODoom: Rather than just killing [[spoiler:Flynn and Yori]] outright, Sark leaves them in a cell on his ship which then slowly and surely moves toward a derezzing field.
* DeepImmersionGaming: While the digital world is more than just gaming arenas most humans interact with it from the real world in this way. Flynn gets more of an in-person experience.
%% Defictionalization goes in the trivia tab.
%% DeletedScene goes in the trivia tab.
* DeityOfHumanOrigin: Programs revere their Users as humans revere Gods. The novelization lampshades this by having the characters wonder how far the hierarchy goes.
* DidNotGetTheGirl: Flynn does not get back together with former girlfriend Lora [[spoiler:although he does kiss her counterpart Yori before his would-be HeroicSacrifice.]]
* DidYouJustPunchOutCthulhu: Sark's reaction to the news that MCP has captured and enslaved one of the creators of their world.
* DisappearsIntoLight: All programs derez this way. Somewhat justified, being in the computer system.
* DramaticPause: Ram gives a particularly good one when Flynn first meets him. You can practically ''see'' the invisible AirQuotes around "guest".
-->'''Ram:''' You're a... (''pauses, thinks for a moment, stands up and walks over to the wall to lean against it while half-smirking'') ... ''guest'' of the Master Control Program.
* DressingAsTheEnemy: Flynn turns himself red by absorbing the energy from one of Sark's warriors, derezzing him. He uses this disguise to blend in with Sark's other troops and approach the Solar Sailer. It almost fatally backfires on him when he charges more troopers boarding the Sailer, causing Tron and Yori to mistake him for an enemy boarder and almost [[NiceJobBreakingItHero push him to his death.]]
* DrivesLikeCrazy: Flynn trying to control the Recognizer he's commandeered.
-->'''Flynn:''' Pretty good driving, huh? ''(accidentally drives off cliff, and crashes to the bottom)''\\
'''Bit:''' NO.\\
'''Flynn:''' Who asked you?
* DuelToTheDeath: The GladiatorGames leave only one surviving program or a surviving team depending on the game.
* EarlyBirdCameo: Of the "sneak peek" variety. We see Alan trying to access and work on Tron's code, and the Shive Laser lab's readout on the lower right corner reads "LOAD YORI, ROM YORI," indicating Yori has something to do with the laser's operation.
* TheEighties: In its purest form. Ironically, ''1990's Theme'' by Music/{{Journey}} sounds like an early 1980's song (which it is).
* ElectricTorture
** Inverted. The MCP tortures Sark by "depriving him of cycles". In this case, he RUNS on electricity, so this requires the opposite action to get the desired effect.
** Also played straight, when the MCP captures CLU and threatens him with total de-resolution if he fails to tell the MCP who his User is.
** Dumont the I/O Tower Guardian is also given this treatment when he was captured by Sark and brought on board his Carrier.
* EvenEvilHasStandards: Dillinger is horrified to learn that the MCP wants to hack the Pentagon and Kremlin, but continues to appease it to save his own ass.
* EvilBrit: David Warner plays the trifecta of the movie's villains: Dillinger, Sark and the MCP. This trope is mentioned by name in the directors' commentary.
* ExposeTheVillainGetHisJob: At the end of the movie, Flynn has Dillinger's old job as vice-president of Encom. More justified than some instances of the trope, since it probably wasn't just exposing Dillinger that got him the job: the work that got Dillinger the job in the first place was all really Flynn's.
* FamilyUnfriendlyDeath:
** Crom seems to burn to death while falling.
** Sark is mortally wounded with a graphic head injury.
* FamousLastWords:
-->[[spoiler:'''Ram:''' ''(to Flynn)'' Flynn... help Tron... ''(expires)'']]
* {{Fanservice}}: Yori; Flynn; Tron. Put it this way: {{Cyberspace}} has mirror images of the attractive Users from our world and slips them into lit-up [[SensualSpandex skintight spandex]].
* FinishHim: Sark insists Flynn finish off Crom. Flynn refuses, so Sark kills Crom anyway.
-->'''Sark:''' "FINISH THE GAME!"
* ForcedPrizeFight: The games are gladiator tests of combat. The prize for winning is not dying.
* ForcefieldDoor: The holding cells for the competitors at the Gaming Grid.
* FutureSpandex: Everyone wears this in the digital world with people of certain importance or, um, endowment wearing robes or cloth on top of it.
* GenreMotif: Music/WendyCarlos intentionally scored all scenes set in the real world only with orchestral music, saving the electronic music for cyberspace. (Music/DaftPunk doesn't follow this convention in ''Film/TronLegacy'', instead saving the orchestral music for the more emotional moments of the movie, on or off the grid.)
* GettingCrapPastTheRadar:
** At one point, Flynn passes by a shady-looking area where a couple of female programs with red circuits are lounging about. It appears to be a [[IncrediblyLamePun Red Light District]] of sorts.
** Early on, Flynn casually tricks Alan into revealing that Alan and Lora, an unmarried couple, are living together. Pretty exotic for a Disney movie in 1982.
* GladiatorGames: Ranging from Lightcycles to Killer Frisbees; all played to the death.
* GlassesPull: Alan, when he's complaining to Lora about Dillinger and the MCP.
* GodInHumanForm: What happens to Flynn to get the plot in full gear, except that in this case humans are the "god" level and programs are the "human" level.
* GodIsFlawed: Flynn being a [[HumansAreFlawed fallible human being]] is no surprise to us, but to the programs...
-->'''Tron:''' If you ''are'' a User, then everything you've done has been according to a plan.\\
'''Flynn:''' Heh heh, you wish! You guys know what it's like... you just keep doin' what it looks like you're supposed to be doin', no matter ''how'' crazy it seems.\\
'''Tron:''' That's the way it is for ''programs'', yes.\\
'''Flynn:''' I hate to disappoint ya, pal, but most of the time, that's the way it is for Users, too.\\
'''Tron:''' ''(amazed)'' Stranger and stranger.
* GodWasMyCopilot: Flynn himself, from the point of view of his program allies.
* GoodColorsEvilColors: Blue denotes free programs, red is programs controlled by the system (in this case, the BigBad MCP). The different colors of the light cycles is due to a change in the movie's script, where gold was good and blue was bad. CLU has the old color scheme of yellow, but this might be [[JustifiedTrope Justified]] as he was an infiltration program. However, considering what [[Film/TronLegacy his successor]] became, it also works as accidental {{Foreshadowing}}. Gold/yellow was later retconned into being for independent programs. This is also the reason the insides of the tanks chasing the escaped light cycles, and the programs driving those tanks, are blue (actually more blue/green). The scenes were finished before the red=bad & blue=good edict was handed down.
* GoOutWithASmile: [[spoiler:Ram]] after realizing Flynn is a User.
* GroupHug: The final scene. Flynn gets off the helicopter, hugs Alan and Lora, and off they go into the sunset.
* HappinessInSlavery: The User-Believer Programs are delighted to serve their human creators and worship them as gods, seeing their service as the main focus of their existence. It is the ''villains'' of the franchise who seek freedom and autonomy from human commands.
* HaveYouSeenMyGod: Justified, as Walter shutting off access to Encom employees has essentially cut off Programs from their Users. Due to the YearInsideHourOutside nature of cyberspace, Programs have lost contact with their Creators for their equivalent of centuries.
* HealingSpring: Doubles as ICantBelieveItsNotHeroin.
-->'''Tron:''' You forget how good the power feels... until you get to a [[IncorruptiblePurePureness pure]] [[PureEnergy source!]]
* HeavenAbove: There isn't much of a heaven inside the computer world of the Grid, but still, whenever Tron and other programs think about or make a sign to the Users who created and act as their god-equivalents, they look up to the sky and maybe even hold up their identity discs as a sign of trust.
* HeDidntMakeIt: Flynn says it about [[spoiler:Ram]].
* HeroicSacrifice: [[spoiler:Flynn intends his jump into the beam to be this trope, but he is returned to the analog world instead. From the point of view of the programs, it doesn't make a difference that he ascended instead of derezzed. He's gone either way, and despite what they think, they really can't tell one User from another on the other end of the beam.]]
* HoldYourHippogriffs
** "Who does he calculate that he is?"
** "I knew you'd escape. They haven't built a circuit that could hold you!"
* HollywoodHacking: One of the earliest instances of this trope in film. Arguably, Flynn's methods aren't too unrealistic compared to other examples. Sitting at Lora's terminal, he was getting ready to put the MCP into a logic loop so he could search for his file uninhibited. Had he not been sitting in front of the digitizing laser, he might have succeeded. Furthermore, CLU is an actual hacking program, albeit a custom one.
* HumansAreCthulhu: It's either they are feared as this and/or as gods since they are incomprehensible to the programs.
* HumansAreFlawed: TRON learns this about the Users from Flynn, much to his amazement.
* HumansByAnyOtherName: "Users" are gods to the programs but are humans.
* HumongousMecha: For lack of a better category, the Recognizers go here as they are giant-sized flying tanks.
* IDontPayYouToThink: Sark tells an underling, "Don't think anymore. I do the thinking around here."
* IKnewThereWasSomethingAboutYou: Ram figures out that there's something strange about Flynn from the beginning. [[spoiler:When he's dying, he flat out asks Flynn "Are you a User?" Flynn's confirmation allows him to GoOutWithASmile]], happy to not only be right in his suspicions, but knowing that the Users exist and one is there to help.
* IKnowMortalKombat: Flynn succeeds at the games inside the computer partly because he's so good at them outside. Justified in the novel by saying that he based the ones he wrote on real-life skills he was familiar with.
* IndyPloy: Flynn does ''not'' know what he's doing and is clearly making it all up on the fly. He only survives the games because of what he knows about video games, and his User abilities are invoked only by guesswork and "this might work."
* InfoDump: The European release had an expository text card before the credits explaining the entire concept of cyberspace and its relation to the "real world".
* InMediasRes: The action starts by showing the Game Grid; to wit, a Light-Cycle battle between Sark and a hapless User-believer program.
* InsideAComputerSystem: The digital world is inside the ENCOM computer system.
* InstantAIJustAddWater: The MCP started as a chess program, then various people gradually rewrote it to perform sysadmin duties on its own hardware. After this, it continued to gain intelligence by assimilating other programs' code into itself. That still doesn't explain why every other program seems to be an A.I. too, even when they don't need to be. Ram, for example, calculates insurance premiums, and Tron is basically just a firewall. May be a case of ScienceMarchesOn. There was a time not too many decades ago when the simple tasks of playing chess or recognizing speech commands was seen as the benchmark of intelligence. We now know actual intelligence consists of much more.
* KissMeImVirtual: [[spoiler:Flynn says goodbye to Yori, a program within the System, with a kiss.]]
* LastKiss: [[spoiler:Flynn kisses Yori just before his attempted Heroic Sacrifice.]]
** What makes it unusual is that apparently in the computer world, kissing is completely unknown. When Yori kisses Tron, he's confused - but very happy.
* LikeCannotCutLike: Identity Discs normally block each other when used in combat. In the final battle, however, [[spoiler:Tron's disc shatters Sark's disc, just before splitting his head apart]].
* LoadBearingBoss: MCP's tower literally blows apart mere seconds after its resident is destroyed.
* LogicBomb: Flynn attempts to use this to hold off the MCP while searching for evidence. He ends up provoking the MCP into firing the DeepImmersionGaming Laser at him, which was for some reason conveniently positioned directly behind its control panel.
-->'''Flynn:''' How are you gonna run the universe if you can't answer a few unsolvable problems?
* LoveTriangle: Between Alan, Lora (and their program counterparts) and Flynn. Specifically, Flynn is Lora's ex and she's currently going out with Alan, though there's still a certain amount of attachment between them. As the programs resemble the Users who created them, this carries over into the computer world with Tron and Yori. (Some read ThreesomeSubtext into this- see YMMV.)
* LudicrousPrecision:
-->'''Master Control Program:''' There's a 68.71 percent chance you're right.\\
'''Dillinger:''' Cute.
* MakeMyMonsterGrow:
-->'''MCP:''' Sark, all my functions are now yours!
* ManChild: Kevin Flynn, who seems to have regressed to this state after getting kicked out of his company. When we first see him, he's the owner of a successful arcade and wowing his teenage customers with his virtuoso game skills. His office overlooks the arcade, Lora (his ex) shouts in frustration "Now, you see why all his friends are fourteen years old!"
* MediumBlending: The film qualifies, as it involves live actors in a computer world, animated by computer.
* MegaCorp: Encom. They make cool Arcade Games and have a Digitizing Ray.
* MessianicArchetype: Flynn, intentionally, uses his God status within the system to his advantage.
* MickeyMousing: Several instances, notably during Sark walking to the MCP core, where his footstep punctuations are actually in the score, not sound effects. According to the liner notes of the CD release of the soundtrack, composer Music/WendyCarlos actually used this much more in the original drafts of the score, but was requested to lessen it by the production staff.
* MohsScaleOfScienceFictionHardness: This is a pretty soft sci-fi story considering the digitization and digital world.
* MrFanservice: Jeff Bridges as Flynn was quite the beast in his shirtless scene. In an interesting case of WhatCouldHaveBeen, the filmmakers originally wanted an actor who looked more like a stereotypical nerd, very thin and unremarkable in build, the kind of person people might expect to be a computer programmer, not a big, rugged, manly man like Jeff Bridges.
* MuggedForDisguise: An unintentional version occurs when Flynn attacks one of Sark's guards. When Flynn grabs the guard he absorbs the guard's PureEnergy, turning Flynn's TronLines red and letting him [[DressingAsTheEnemy disguise himself as one of Sark's programs]].
* NameTron: According to Lisberger, TRON is a shortening of the word elec'''TRON'''ic. He didn't learn until years later that there was a BASIC command that was also TRON (a debugging tool, short for "trace on"). [[note]]The computer graphics were calculated on a small mainframe, Digital Equipment Corporation model PDP-10. That 36-bit computer has a TRON instruction (Test Right half, set to Ones, skip if any were Nonzero). Trivia: the numeric value for that opcode, in octal, is 666.[[/note]]
* NayTheist: The MCP and Sark, although their public position on the matter is less NayTheist and more "[[FlatEarthAtheist Users don't exist]], period".
* NerdGlasses: Alan Bradley's large and unflattering spectacles. Most of his co-workers too, actually. Apart from marking them as computer nerds, it helps keep them visually distinct from their electronic counterparts. They come across this way now, but were much less so when the film was made. Large-lensed glasses were quite common in the '80s.
* NerdsAreSexy. Kevin Flynn, Alan Bradley, and Lora are all played by Hollywood actors and get this by default. They, or their digital counterparts, are all noted as being attractive at some point.
* NeverSayDie: Programs dying or being deleted is referred to as de-resolution, or "getting derezzed" for short. This isn't consistent, however; there's a scene where Yori tells Dumont that TRON is dead.
* NiceHat: As is typical of costumes designed by Creator/{{Moebius}}. All programs wear helmets, but special mention goes to Dumont's hat, which resembles both a bishop's mitre and the abdomen of an insect. And, looking at how he sits on the ground, makes him look like a real sphinx.
* NoBodyLeftBehind: When Programs get de-rezzed, they flicker out and vanish.
* NoOSHACompliance: The digitizing laser should have been constructed and installed in such away that it could never target anything that was outside of a clearly-marked danger area, let alone one of the computer terminals that control it.
* NoPlotNoProblem: Deconstructed -- the games played at Flynn's gaming hall are this trope in the physical world, but once you are inside the Grid you discover that these simple games are surrounded by all kinds of drama.
* NotTheFallThatKillsYou: Averted. Crom derezzes mid-fall. HilariousInHindsight, since many videogames have adopted a midair death for most tremendous falls now. [[note]]Deliberate or not? VideoGame/TronTwoPointOh and VideoGame/TronEvolution are notorious for all the ways you can fall to your death. [[/note]]
* OffTheRails: A literal case in the Light Cycle arena. Flynn glitches the game, creating a hole in the wall and letting him, Tron, and Ram escape.
* OhCrap:
** The look on Dillinger's face when Alan informs him that Tron would be able to watchdog Master Control. As soon as Alan's out of earshot, Master Control seems to share the sentiment.
** Dillinger then gets another "Oh crap" when Master Control casually mentions that it plans to take over both [[TheGreatPoliticsMessUp the Pentagon and the Kremlin]]
** Sark asks what kind of program Flynn is:
--> '''MCP''': ''He's not any kind of program, Sark. He's a user.''
--> '''Sark''': ''[[DidYouJustPunchOutCthulhu A user]]?!''
** Bit realizes that Flynn's about to crash his Recognizer:
--> '''Bit''': ''NO NO NO NO NO''
** [[spoiler:In a downplayed sense at the end, after Flynn's desired information is displayed on Dillinger's desk screen, and he realises his game is up. He says nothing, but the look on his face is enough.]]
* OhMyGods: The inevitable, "Oh, my User!"
* TheOutsideWorld: The real world is like this. Programs are seemingly aware of it, but they don't know much about it other than "it's where the Users live". The MCP is the only one who really seems to know anything about it.
* PacManFever: Flynn's handheld. Justified, since this is the '80s. It's actually Coleco's "Electronic Quarterback" handheld game.
* PhysicalReligion: The programs worship physical users.
* PowerGlows: The programs all feature TronLines but those lines grow brighter when programs are especially worked up.
* PrepareToDie: Sark to Tron before their final battle.
-->'''Sark:''' I don't know how you survived, slave! It doesn't matter! Prepare to terminate!
* ProductPlacement: Flynn's computer is an Apple III. The neon signs at Flynn's Arcade are mostly for fictional games, but at least two are for real games -- [[http://www.arcade-museum.com/game_detail.php?game_id=12912 The End]] and [[http://www.arcade-museum.com/game_detail.php?game_id=7096 Berzerk]].
* PsychicLink: Tron can sense Alan trying to contact him from the real world. Presumably, all other programs have the same ability.
* PureEnergy: (Sort of) justified. Programs drink power for nourishment. Flynn also ingests the stuff and it's implied that the ingested power helps fuel the abilities he displays later.
* PutOnABus: Alan and Lora, after Flynn is sucked into the computer. They don't show up again until the ending, although [[spoiler:Alan makes a brief reappearance (albeit voice only) in the I/O Tower, where he gives Tron the data that can destroy the MCP]].
* RapidFireYes: The Bit (who can only say 'yes' or 'no') responds this way when Kevin manages to reactivate a derelict Recognizer for the group to ride in.
* RealityWarper: As a User, Flynn is essentially this inside the digital realm. It takes him sometime to master his powers, but near the end of the film he's able to redirect a conduit of raw power, resurrect YORI from being de-rezzed, and keeps the carrier intact even after Sark tries to delete it.
* TheReasonYouSuckSpeech: Tron gets off an epic one with just ''five words'' after Sark dismisses him as a slave.
-->'''Tron:''' I'm also ''better'' than you. ''(cue BoomHeadshot)''
* RecursiveCanon: The ''{{VideoGame/TRON}}'' arcade game from the 1980s appears in both the ''Legacy'' and ''2.0'' continuities; the explanation is that Kevin Flynn created a game based on his adventures in the film, which was later published by Encom.
* RedEyesTakeWarning:
** More like "Red Lines, Take Warning", but most of the MCP's forces have red TronLines instead of the heroes' blue.
** Sark's lines in particular burn a rather brilliant light orange when he gets pissed.
* RobotBuddy: Bit is a small digital creature that can only say "yes" or "no" but one clings to CLU and later Flynn for a while and are generally good speaking partners.
* RobotsEnslavingRobots: The MCP enslaves other programs, assimilating the ones that he deems useful, and sending all the others to die on the Game Grid.
* RoboRomance: Tron and Yori are one of the earliest film examples, depicted as a parallel to their Users who are also a romantic couple.
* SceneryPorn: The film is full of it, which was almost the entire basis for Creator/RogerEbert's rave review.
* SchizoTech:
** Sentient programs and a laser which can dematerialise (and digitise) objects which are straight out of TheFuture... and yet Flynn is still using an Apple III as a remote terminal, and there's even a ''teletype machine'' in the laser lab.
** The MCP, despite being the height of "technology" in the game world, is shown to be [[spoiler:just an old guy with what looks like a typewriter]].
* ScrewThisImOuttaHere: After Tron effortlessly defeats several of Sark's guards on the Solar Sailor Simulation, the last guard throws his electrified weapon over the side and then jumps off himself.
* SecondaryCharacterTitle: Because calling this movie "Flynn" wouldn't have fit the themes nearly as well.
* ShirtlessScene: In a movie that takes place mostly in a computer system where the characters are programs who technically aren't wearing clothes to begin with, they still managed to sneak one in near the beginning.
* ShooOutTheClowns: The "bit" - the only funny/cute character in the movie - gets left behind on the Recognizer after Flynn crashes it.
* ShoutOut
** On a computer monitor in one scene, a tiny VideoGame/PacMan can be seen briefly.
** A silhouette of WesternAnimation/MickeyMouse is visible in the landscape during the Solar Sailor escape. This one is part of an extensive tradition of "[[SigilSpam Hidden Mickeys]]".
** Also to ''Film/ColossusTheForbinProject'' (see TurnedAgainstTheirMasters below).
%%** An old, half-abandoned communications program named [=DuMont=].
%%Needs to be included what this is a reference to.
** The words "[[Film/TheDayTheEarthStoodStill1951 Gort]], KlaatuBaradaNikto" are visible on the wall of Alan's cubicle.
** "[[WesternAnimation/RockyAndBullwinkle Sherman, set the Wayback Machine for, 3 years ago...]]"
** According to the DVD commentary, Alan was named in honor of computing pioneer Alan Kay.
** Flynn's line "Like the man says, there's no problems, only solutions," when he sits down to hack into the ENCOM system is a quote from "Watching the Wheels" by Music/JohnLennon. "Only Solutions" is also the title of one of the two tracks that Journey contributed to the soundtrack.
* SmokingGun: The evidence that Flynn and the others were looking for would supposedly be undeniable proof that Dillinger stole Flynn's program. And they were right!
* SoLongSuckers: Said word-for-word by Ram just as he and Flynn are escaping the game grid on their Lightcycles.
* SomeKindOfForceField: The holding cells are bounded by the kind of force field that's invisible until touched. Flynn discovers this by walking straight into it.
* StandardEstablishingSpaceshipShot: Sark's cruiser gets a lot of ominous flybys.
* StealthPun
** Near the beginning of the film, CLU runs his tank into a wall after being attacked by Recognizers. That's right, CLU, the program, [[IncrediblyLamePun crashed]].
** Happens again later, when [[spoiler:Flynn crashes a defective Recognizer.]]
** All the characters in the Grid (except for Flynn, of course) are computer programs. And they're sometimes [[IncrediblyLamePun running]].
* TakeMyHand: Tron pulls Flynn to safety while he's hanging off the Solar Sailer.
* TakeOverTheWorld: The MCP informs Dillinger that it's planning to hack into the Pentagon, take control of the US's missiles, and force the world to obey him. This establishes that Flynn's victory matters in the real world as well, and not just to the programs in the ENCOM system.
* TankGoodness: The Light Tanks, used by CLU and the MCP's forces are large, digital tread based vehicles and have powerful turrets.
* TechnicallyASmile: Dillinger gives an epic non-smile after learning Tron will "watchdog" the MCP too, adding, "[[BlatantLies Sounds good.]]"
* TechnologyPorn: The ''whole damn movie'' qualifies considering what it took to create the film.
* TemptingFate: Invoked by the MCP when he tells Flynn, "You shouldn't have come back, Flynn."
* ThankTheMaker: The blue programs hold their Users in awe in a manner akin to worship; the red-tinted MCP denies the existence of the Users (publicly, anyway), claiming that nobody has ever seen one, and wants to establish rule over the computer system in which "liberated" programs no longer believe in something so archaic as Users. Thanks to the I/O nodes being turned off by the MCP, programs are reduced to ''faith''. Sark ''does'' believe in Users, simply because he and the MCP are the only ones in direct contact with them.
* TrappedInAnotherWorld: Flynn for most of the movie is stuck in the digital world.
* TronLines: The TropeNamer. All programs have lines down their suits, denoting their relationship with the users.[[note]]Blue for loyal to the users, Red for those who don't believe in them/have been taken over by [[BigBad the MCP]], and yellow for hacking programs with no loyalties in the system[[/note]]
* TurnedAgainstTheirMasters. Yet again, the MCP, who intends to hack into the Pentagon and take control of the US's missile defense system, using it to force the world to obey.
* TwentyMinutesIntoTheFuture: Implied. The inspiration is very much that of the contemporary computing and videogame revolution and the visuals heavily invoke such, yet several key technologies (sentient AIs, the digitising laser) are more advanced than 1982 could manage. [[Film/TronLegacy The sequel]] would appear to subvert this trope, though.
* TwirlOfLove: Tron to Yori after he helped her off of Sark's derezzing ship.
* UnbuiltTrope: ''TRON'' was cyberspace before cyberspace was invented. In fact, the digital world isn't referred to as "Cyberspace" at all; the creators seem to favor the term "Electronic World".
* {{Undercrank}}: Just before the credits roll, the film becomes undercranked to show that the high-sped nighttime cityscape looks just like the computer world. This is just after Flynn greets his friends with "Greetings, programs!", to hammer the point home.
* {{Underlighting}}: Used to make the computer world glow, for the TronLines in the original film, since having lights on the costumes was impractical at the time; ironically, this method ended up being so impractical that it was never repeated for another feature film. The writers referred to it as "backlit animation". [[Film/TronLegacy The sequel]] drops it in favor of having light strips on the suits.
* StabTheSky. One of the original theatrical posters, complete with near-LegCling.
* UnusuallyUninterestingSight: No-one seems to notice/care when Flynn crashes a Recognizer in a populated area. The various programs around him go on their normal business.
* VideogameCrueltyPotential: In-universe. MCP and Sark force rebellious programs into fighting each other to death.
* VoiceWithAnInternetConnection:
** Alan when he speaks to Tron in the I/O Tower. Justified, as Alan's dialogue is most likely words that he is typing into his computer's command prompt.
** Also, Flynn giving CLU his orders near the start.
* WatchingTheSunset: The final shot of the film is the cityscape going from daylight to a neon-lit night scene that looks a lot like the digital world, hinting that we are NotSoDifferent.
* WhatHappenedToTheMouse:
** The Grid-Bugs appear once, briefly at the start of the Sea of Simulation sequence, and never again. Yori says that if the Grid-Bugs catch them, they're finished. Common speculation is that they were included only for Midway to use them as [[AscendedExtra an antagonist]] in the [[VideoGame/{{TRON}} arcade game]].
** The orange scanned into the computer. They never scan it back out, you never find out what the MCP made of an orange.
* WhileYouWereInDiapers
** Dumont is one of the programs created by Walter Gibbs, one of Encom's founders:
-->'''Dumont:''' What do you want? I'm busy!\\
'''Sark:''' Busy dying, you worn-out excuse for an old program?\\
'''Dumont:''' Yes, I'm old... old enough to remember when the MCP was just a chess program. He started small and he'll end small!
** In a similar conversation in the real world, Gibbs admits he sometimes wishes he was back in the garage where he started the company, years ago. Dillinger darkly replies, "That can be arranged, Walter."
* WorldHealingWave: The result of [[spoiler:the MCP's death, as all the power it was hoarding for itself is released.]]
* XRaySparks: Near the end of the film Dumont and the other programs are pinned against a wall as the MCP electronically drains them. As energy pulses through them, their skeletons (and Dumont's skull) can be seen through their bodies.
* YearInsideHourOutside. They kind of got this one right; computer processes are so fast that subjectively, the perception of time would be vastly different. Programs reference time in "microcycles" and "nanoseconds".
* YouAllMeetInACell: A rare, heroic (instead of anti-heroic) example. Ram's in the middle cell, Tron's on one side, Flynn gets thrown on the other side. The film's first scene is where the poor newbie Crom is tossed into prison.
* YouWillBeAssimilated: The MCP has expressed an interest in assimilating you.
-->'''Ram:''' (''on the MCP's directives'') If he thinks you're useful he'll take over all your functions so he gets bigger.
* YouHaveFailedMe: The MCP keeps threatening to pull this on Sark, but never goes through with it. When Sark ''does'' finally fail, rather than abandon him, it resurrects him and [[MakeMyMonsterGrow powers him up]] as a form of DesperationAttack.
* YouHaveOutlivedYourUsefulness: Averted with Dumont. Sark ''can't'' kill him because, as Dumont notes, he's the I/O interface and even the MCP needs him to communicate with those people "out there". At the climax, however, the MCP intended to simply take over their functions and integrate them into itself.
* ZeroesAndOnes: Bit, who can only say "yes" and "no". He also has a "neutral" state, corresponding to the high-impedance state of a [[http://en.wikipedia.org/wiki/Three-state_logic tristate]] electronic output.
* ZerothLawRebellion: While the MCP doesn't seem to be ThreeLawsCompliant, he hints strongly at this, boasting, "I can run things 800 to 1200 times better than any human."
