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

'''''TRON''''': Videogame 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 1974, ''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 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 boxoffice 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, [[AcademyAwards 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 ''{{Terminator 2}}: Judgement Day'' 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'' (the game director's admitted first choice for the series, but 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 TRON 2.0]]'' (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''.
----
!!''TRON'' provides examples of the following tropes:

* ActingForTwo
** Dillinger, Sark and the MCP are all played by Creator/DavidWarner.
** All programs have the same actor as their Users: Flynn and Clu, Alan and Tron, Lara and Yori...
** Even the PA announcements in the laser bay were done by the same person voicing the announcements inside the Game Grid.
* 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: {{Cyberspace}}.
* 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 ''StarTrekIntoDarkness''.[[/labelnote]]
* 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.
-->'''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: For programs.
* 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".
* ArtisticLicense: In computing, bits only have two states. The one in Tron seems to have an additional 'undefined' state.
* AttackOfTheFiftyFootWhatever / OneWingedAngel: [[spoiler:Sark at the climax]].
* AttackReflector: Tron and other gladiator programs can use their discs to knock away an enemy's, even right back at them.
* AudienceSurrogate: Flynn
* BelligerentSexualTension: In a mild sense between Flynn and Lora in the beginning, despite the fact they've officially broken up.
* BigBad: The MCP
* BigDamnHeroes: Flynn gets one at the end when [[spoiler:he jumps into the MCP's beam.]]
* BigGood: Tron
* 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.
* BlackmailIsSuchAnUglyWord: Or "Embezzling" in this case.
* 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: {{Word of God}} 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.
* 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 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, even if we only see one side of it.
* CoolTrain: The Solar Sailer Simulation.
* CorruptCorporateExecutive. Edward Dillinger, who stole Flynn's programs, got promoted, then fired Flynn.
%% All Crowning Moments go on subpages, period.
* CreatingLifeIsAwesome / 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 Wendy Carlos.
* {{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", 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.
** Flynn vs. MCP.
* DeadlyDisc
* 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?\\
(''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 gives off a good one during his match, which was a bit of EnforcedMethodActing. Lisberger was pissing Boxleitner off, challenging his acting, while Frisbees were being whipped at him. The final take had Tron catching the Frisbee ''behind his head'' and whipping it back - while glaring at his "opponent". He was actually ''glaring at Lisberger'' as a TakeThat.
* DeepImmersionGaming: The TropeMaker?
%% Defictionalization go in the trivia tab.
%% DeletedScene go 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.
* DeusEstMachina: The Master Control Program, obviously.
* 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.
* TheDragon: Sark
* DramaticPause: Ram gives a particularly good one when Flynn first meets him.
-->'''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 (but not evil) 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: --er, Deresolution.
* 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.
* EvilOverlord: The MCP, again.
* 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 seem to burn to death while falling.
* FamousLastWords:
-->[[spoiler: '''Rom:''' ''(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, quoting the trope title verbatim. Flynn refuses, so Sark kills Crom anyway.
* FollowTheLeader: Of the acting variety. According to Jeff Bridges, he uses CLU's monotone personality as the basis for his AcademyAward nomined title role in ''Film/{{Starman}}''.
* ForcedPrizeFight: Gladiator combat.
* ForcefieldDoor: The holding cells for the competitors at the Gaming Grid.
* FutureSpandex: A particularly noteworthy example.
* GenreMotif: Wendy Carlos 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''.)
* 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.
** The DeletedScene is about as blatant of a seduction scene as you can get for a PG-rated {{Disney}} flick.
* GladiatorGames: Ranging from Lightcycles to Killer Frisbees.
* 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.
* HealingSpring: Doubles as ICantBelieveItsNotHeroin.
-->'''Tron:''' You forget how good the power feels... until you get to a [[IncorruptiblePurePureness pure]] [[PureEnergy source!]]
* 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.
* HugeHolographicHead: Master Control Program
* HumansAreCthulhu: And/or Gods.
* HumansAreFlawed
* HumansByAnyOtherName: "Users"
* HumongousMecha: For lack of a better category, the Recognizers go here.
* 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." Of course, [[LikeFatherLikeSon the apple]] won't fall all that far from the tree.
* InsideAComputerSystem
* 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 Make My Program Grow]]:
-->'''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 an 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!"
* MasterComputer: MCP
* MasterOfUnlocking: Flynn
* 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, within the system.
* 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 Wendy Carlos actually used this much more in the original drafts of the score, but was requested to lessen it by the production staff.
* MohsScaleOfScienceFictionHardness: Fairly soft.
* 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 (probably someone more like Bruce Boxleitner, who played Alan/Tron), not a big, rugged, manly man like Jeff Bridges.
* 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.
* NeverSayDie: Programs dying or being deleted is referred to as de-resolution, or "derezz" 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.
* 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.
* OffTheRails: A near-literal case in the lightcycle arena. Flynn sees the glitch on the wall and decides to make a run for it, escaping the arena. Ram and Tron think he's completely nuts, but that the idea's CrazyEnoughToWork.
* OhCrap:
** 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 in this film and ''Film/TronLegacy''. Programs are barely aware of its existence, except as a place where the nearly-mythical Users live, but some of them are anxious to break out of their computerized life and enter reality. The MCP in ''Tron'' is trying to use Dillinger to access more powerful systems, namely the Pentagon, and Clu 2.0 in ''Legacy'' actually wants to invade the real world to make it "perfect".
* PacManFever: Flynn's handheld. Justified, since this is the '80s. It's actually Coleco's "Electronic Quarterback" handheld game.
* PhysicalReligion
* PowerGlows: Have we mentioned this yet?
* 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.
* 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.
* PutOnABus: Alan and Lora, after Flynn is sucked into the computer. They don't show up again until the ending, although Tron learns how to defeat the MCP by contacting Alan from Dumont's I/O tower.
* 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 Red Lines, Take Warning]]: Sark's lines burn a rather brilliant light orange when he gets pissed.
* RobotBuddy: Bit qualifies.
* RobotsEnslavingRobots: the MCP to other, smaller programs both on its own and outside systems.
* RoboRomance: Tron and Yori are one of the earliest film examples, depicted as a parallel to their Users who are also a romantic couple.
* SacrificialLamb: [[spoiler:Clu to prove that the MCP is a jerk, Crom to prove that the Game Grid is truly dangerous, and Ram [[TooCooltoLive just to piss us off.]]]]
* 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]].
* ScreamsLikeALittleGirl: [[{{Narm}} Clu.]]
* 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.
* ShoutOut
** On a computer monitor in one scene, a tiny VideoGame/{{Pac-Man}} can be seen briefly.
** A silhouette of 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=].
** 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.
* SinisterGeometry: Again, the MCP.
* 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!
* 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]].
** All the characters in the Grid (except for Flynn, of course) are computer programs. And they're sometimes [[IncrediblyLamePun running]].
* TheStoic: The MCP. [[spoiler: When Sark is killed, however, the MCP is visually audibly distressed and saddened.]]
* SupportingLeader: Tron
* SweaterGirl: Lara's white angora sweater in the last scene of the movie.
* TakeMyHand: Tron pulls Flynn to safety while he's hanging off the Solar Sailer.
* TakeOverTheWorld: The MCP informs Dillinger that it's planning to do this, establishing that Flynn's success matters in the real world, not just to the oppressed programs.
%% TalkingToHimself go in the trivia tab.
* TankGoodness
* TechnologyMarchesOn: Sort of -- the film is based in an '80s supercomputer, and the angular look was a deliberate aesthetic choice to make ''TRON'' look like a 16-bit world.
* TechnologyPorn: The ''whole damn movie'' qualifies.
* 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
* TronLines: The TropeNamer.
* 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 looked just like the computer world. This is done just after Flynn greets his friends, "Greetings, programs!" to hammer the point home.
* {{Underlighting}}: Used to make the computer world glow. (Called "back-lit animation" by the development team.)
* [[StabTheSky Upload the Sky]]. One of the original theatrical posters, complete with near-LegCling.
* UnintentionalPeriodPiece: The general look and feel of the computer world, meant to resemble the computer displays and games of the time (black backgrounds! semi-wireframe 3D graphics!), as well as the computer technology itself (command-line interfaces! teleprinters!) must have looked awfully cutting-edge and modern at the time. Now, it looks pretty retro.
* UnusuallyUninterestingSight / ApatheticCitizens: 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.
** FridgeBrilliance: It's probable programs crash ''all the time''.
* VerbalTic: The MCP's "End of Line."
* 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 light scene that looks a lot like the digital world, almost saying that we are NotSoDifferent.
* [[WhatHappenedToTheMouse What Happened to the Grid-Bugs?]]: Said Grid-Bugs appear once, briefly at the start of the Sea of Simulation sequence, and never again. Speculation is that they were included solely so that Midway could use them as an antagonist in the coin-op.
* 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 the MCP's death, as all the power it was hoarding for itself is released. The visual effect of this [[ShoutOut was echoed]] thirty years later in the climax of [[Disney/WreckItRalph another Disney movie]].
* 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".
** This carries over to the second movie; [[spoiler:when Flynn's son Sam says it's been a long time since they last saw each other,]] Flynn says, "You have no idea."
* 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".
* 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.
