->''"What's the most resilient parasite? A bacteria? A virus? An intestinal worm? [...] An idea. Resilient, highly contagious. Once an idea has taken hold in the brain, it's almost impossible to eradicate. An idea that is fully formed, fully understood? That sticks."''
-->-- '''Dom Cobb'''

'''''Inception''''', a 2010 film from director Creator/ChristopherNolan, works like a [[TheCaper heist film]] in reverse: instead of taking something, the main character must leave something behind.

[[Creator/LeonardoDiCaprio Dominic Cobb]] works as a freelance "extractor": using [[AppliedPhlebotinum a specialized set of drugs]], Cobb and his team share dreams with their targets (usually individuals with lots of power and money), which allows Cobb to find and open the safes and vaults within said dreams that contain secrets he can sell to his clients. Cobb's skills in understanding the human mind make him one of the world's best extractors, but his job has turned him into an international fugitive who can't return home to his family in the United States. When an attempt to extract information from a Japanese business magnate named [[Creator/KenWatanabe Saito]] goes wrong, Cobb goes on the run from his current employers.

Saito catches up with Cobb and makes the extractor an offer: he'll arrange to wipe Cobb's criminal record (which would allow him to go home) if Cobb can manage to perform an [[TitleDrop inception]] on one of Saito's rivals. Whereas extraction involves stealing ideas or information already in somebody's head, inception involves the ''insertion'' of an idea into someone's head [[OpinionChangingDream in a way which convinces the target that they independently conceived the idea]]. Cobb accepts Saito's proposal, even though he knows it has a catch: nobody has ever pulled off a successful inception, as the targets always realize that they didn't come up with the inserted idea.

To attempt the impossible, Cobb [[AvengersAssemble assembles]] a BadassCrew of experts: longtime extraction partner [[Creator/JosephGordonLevitt Arthur]], dreamworld-building architect [[EllenPage Ariadne]], expert forger [[TomHardy Eames]], and chemist Yusuf (who devises the specialized sedatives that make extraction possible). The task requires them to perform a very risky "[[ImpossibleMission dream within a dream within a dream]]" scenario which will allow the team to bury the idea deep enough to leave no trace of their influence. As Cobb's group works their way into the target's mind, a complication Cobb failed to warn them about arises: inside the dream world, [[EnemyWithin Cobb's subconscious demons]] makes for a worse enemy than their target's -- and if they die in the dream, well, the sedatives assure that [[YourMindMakesItReal they simply don't wake up]]...

----

!! ''Inception'' extracted the following tropes from the minds of humanity:

[[foldercontrol]]

[[folder:A-G]]
* ActionPrologue
* AdultFear: The protagonist is forced to flee his home and his country, leaving his very young children behind, possibly forever. There's also the horrific situation when he has to watch his beloved spouse succumb to mental illness and suicide - and realize it was his mistake and that he was responsible.
* AirVentPassageway: {{Exaggerated}}. In the final maze there were air vents large enough for a full-grown man to stand upright, and bypassed the maze completely. Justified in that they were only there because Eames deliberately had Ariadne install them.
* AlienGeometries: One of the architect's tasks is setting up [[Creator/MCEscher Escheresque]] loops in the dream world, in order to confuse and trap the projections if they become hostile.
* AllJustADream: Played with. From the perspective of one level of the dream world higher, whatever happens in each dream layer is AllJustADream, but things that happen while you're dreaming ''can'' have very real results in the real world. Also, one theory surrounding the film is that [[spoiler:the entire thing is in Cobb's head and that ''he's'' the one who's had inception performed upon him to believe that his dream is the real world]]. [[spoiler:In a dream, the top will never fall, and it sure seems to stay up for a long time, but it clearly wobbles before [[BlackScreenOfDeath the credits roll]]. But it may or may not straighten out, and we don't see it fall. It also leaves a second question on top of "Was it a dream?": If it was a dream, ''how much'' of it was a dream?]]
** Well, [[spoiler:[[http://screenrant.com/michael-caine-inception-ending-batman-3-benm-80670/ according to Michael Caine]], the top wobbles and Cobb deliberately does not check, as he has confidence that he's in reality]], and WordOfGod vaguely alludes to this as well. But Caine's theory hasn't stopped people from coming up with their own interpretations of the ending.
** Another popular interpretation is that [[spoiler: the spinning top is not actually his totem - since the top was what he used to make Mal doubt the reality of their limbo world. The theory is that his actual totem is his wedding ring]].
* AluminiumChristmasTrees: [[http://www.youtube.com/watch?v=mwdRD3AZBfc A top actually CAN spin for a ''really'' long time, depending on the design]].
* AmbiguouslyGay: Eames.
* AmbiguousSituation: The movie ends with [[spoiler:Cobb being so happy to see his children again that he forgets to check if his totem stops spinning or not. Will it stop spinning shortly after the scene? If so, the ending is HappilyEverAfter. If not, it's kinda a LotusEaterMachine]].
** This is also invoked (earlier in the film) by Mal and Cobb, who keep taking opposing standpoints on ThisIsReality versus AllJustADream.
* AnachronicOrder: Not to the level of previous Nolan films, but [[spoiler:the beginning chronologically takes place near the end]].
* AndIMustScream: Limbo. [[spoiler:[[SubvertedTrope Or not]] -- since you are a PhysicalGod there, it's far from suffering; Mal and Cobb didn't seem to mind it.]]
** [[spoiler:It's not so much limbo as it is the ''effects'' Limbo has on the mind. Since, once there, you are a PhysicalGod, you have decades worth of time in a single afternoon... Limbo is, in a way, a LotusEaterMachine version of the perfect world. Leaving it is likened to a drug-addict off their fix... you can't just up and leave, you'll always want to go back. You'll ''"need"'' to just to have some sense of feeling. And that is the grand fear of limbo, because once you tasted it... you never want to leave, even if the door is right in front of you.]]
** The whole caper, if you judge by the events in the first layer of dreaming, lasts no more than 10 hours tops. This means that [[spoiler:it took most characters a maximum of 30 minutes of real-time to get through the movie. Meanwhile, the flight is 10 hours real-time, which leaves Cobb with 9 hours 30 minutes to find Saito – multiplied by 20, by 20, by 20 and by 20 again. That's 1 and a half million hours. So Cobb and Saito were rotting in Limbo for more than 170 years. On realization, it would make even the viewer scream, to say nothing of these fellas.]]
* AntiHero: Both Cobb and Saito have rather selfish motives for messing with Robert Fischer's subconscious, and all the other team members are motivated by either money, curiosity, the thrill of the challenge, or a combination of all these. [[spoiler:They're arguably altering Fischer's subconscious for the better, in that he'll have a more positive outlook on his father and life in general, but it's an outlook that was based on lies.]]
** Even if you put aside their selfish motives, the team's remarkably deceptive and manipulative methods are morally questionable, to say the least.
* AntiVillain: Mal, in a fashion.
* TheAppleFallsFar: Mal's shoe plummeting dozens of stories to the street below [[spoiler: right before she does too.]]
* AppliedPhlebotinum:
** The dreamshare suitcase containing the apparatuses, wires, and a [[BigRedButton big yellow button]]. [[AllThereInTheManual According to supplemental materials]], it is called the [[FunWithAcronyms Portable Automated Somnacin IntraVenous Device]] ([[http://www.pasivdevice.org/ PASIV]]).
** The yellow sedative to stabilize the dreamer by putting him into a deep sleep. A sleep so deep that all sensory input is just about muted, with the precise exception of their inner-ear sense of falling.
*** There seems to be a wide variety of sedatives that can be used for various purposes. The sedative mentioned here, that leaves inner-ear function intact, is but one example. Another is the sedative used when Cobb and Arthur [[spoiler:enter Saito's dreamed dream at the start of the film]], that leaves the dreamers able to feel water. The sedative used on the train does not appear to have any sensory gaps, aside from a vague sense of hearing.
** In the movie it is mentioned that the technology was first created for military applications as a training simulation.
* ArbitrarilyLargeBankAccount: Saito uses his to buy the entire airline for the single airplane they're infiltrating. Purchasing an entire airline in under a month, without attracting attention, would require a staggering amount of money.
* ArcNumber: 528-491. Amusingly, it means absolutely ''nothing'', being just the first six numbers Fischer thought of. As they go deeper and deeper into the dreams, though, Fischer's subconscious starts giving them importance, because hey, he was thinking about those six numbers.
* ArcWords:
** "You're waiting for [[AfterlifeExpress a train]]..."
** "... an old man, filled with regret, waiting to die alone."
** "We can be young men together again."
** "...take a leap of faith"
** "''Non, rien de rien / Non, je ne regrette rien...''"
** "This world is not real." or some variant of the word.
** "[[GrowOldWithMe You said you dreamt that we would grow old together.]]"
** Cobb's comparisons of an idea to a virus only really hit home in Act III.
* AstralCheckerboardDecor: The snow fortress in the third level has floors with this pattern.
* AudienceSurrogate: Ariadne. In a refreshing twist on the trope, she doesn't just sit there and [[TheWatson ask questions so that the more experienced characters can provide exposition]]. She catches on to the idea of dream-sharing rather quickly, and makes an effort to sway Cobb from his self-destructive course. Not to mention that it's ''her'' idea to [[spoiler:go into the fourth level]] after Cobb and Eames have basically given up. In short, she's a character who behaves exactly as the audience likes to believe they would in that situation.
* AustralianAccent: Quite a few, as the old man Fischer dies in Sydney.
* AuthorAvatar: Cobb, if you favor the [[http://bigdamnpictures.blogspot.com/2010/08/inception-interpretations-part-1-dream.html inception-as-metaphor-for-filmmaking]] interpretation.
* AxCrazy: Mal's projection.
* BadassBookworm: Arthur. Cobb mentions that he's in charge of doing the research, and he's smart enough to figure out how to simulate falling in zero gravity. He's also badass enough to pull it off, in limited time, while fighting off mooks. Again, in zero gravity.
** Ariadne designs all the dream levels, complex enough that if Mal hadn't showed up to screw everything up, the mission most likely would have gone smoothly.
* BadassCrew: The Inception team. ''Especially'' Arthur and Eames.
* BadassInANiceSuit[=/=]SharpDressedMan: Everyone, though Arthur kicking ass and taking names in his WaistcoatOfStyle is a standout example.
* BatmanGambit:
** "Mr. Charles" -- [[spoiler:In the second layer of the dream, Cobb tricks Fischer Jr. into participating in the inception plan by convincing him that his godfather Browning is the one that's really invading his dream]]. This plan would only attract attention from the hostile projections once they become aware they're in a dream, thus increasing the danger for everyone involved. Indeed, it's shown that last time this was tried, it backfired ''horribly'' for Cobb, Arthur, and their crew.
** Nolan's plan for getting the film made also seems to have elements of this. Bonus points for using [[Film/TheDarkKnightSaga Batman]] '''in''' the BatmanGambit.
* BattleInTheCenterOfTheMind: Quite a few because most of the movie takes place in a dream and ThePlan involves going very deep into someone's mind.
* BavarianFireDrill: Cobb pretending to be Fischer's security expert in the bar scene, which leads to ComeWithMeIfYouWantToLive.
* BetterThanABareBulb: In-story. The Mr. Charles gambit: [[spoiler:when Fischer starts to near an awareness of the artificial nature of the world, Cobb assumes the role of Dream Security expert Mr. Charles to call attention to the fact he's being dream hacked in an effort to gain his trust and continue the hacking. It works.]]
* BeyondTheImpossible: It's clearly stated that two levels deep is the maximum ''stable'' level. This means anything deeper would send you into Limbo. Subverted the first time: The group uses AppliedPhlebotinum to tweak the rules and reach a third. For the fourth, they just go for it. Overall justified because Cobb disagreed with other dream experts and was a pioneer in the technology.
* {{BFG}}: The grenade launcher Eames uses in the dream when Arthur fails to hit his target.
* BiggerIsBetter: As Eames demonstrates to Arthur in terms of dream weaponry.
* BilingualBonus: The French song used as a signal to wake up is about letting go of the past. Due to the language's love of double negatives, it could be literally translated to "I regret nothing of nothing:" how can one regret something that only took place in a dream? Also, although that part may not be audible in the film, the song famously goes on to say "(I don't regret) any of the evil/hurt inflicted to me" with the word for "evil/hurt" being... ''[[MeaningfulName mal]]''. ItGetsBetter: Marion Cotillard, playing Mal in Inception, impersonated Music/EdithPiaf (singer of the aforementioned French song) in ''La Vie en rose'', the movie that gave her an Oscar (and thus made her known to American audiences).
** Regarding the "double negative" above: repeating a word (especially an adjective or an adverb) in the "X de X" construction is commonly used as an intensifier. While "I regret nothing of nothing" is a possible (if unlikely) translation for "rien de rien", it's really closer to "I ''really'' don't regret anything."
* BilledAboveTheTitle: Leonardo [=DiCaprio=] (makes sense, as he's the lead). In a fair move, the rest of the principal cast (minus [[SirNotAppearingInThisTrailer Dileep Rao]]) are all billed in accordance to their screen time below the title.
* {{Bizarrchitecture}}: The further down into the dream world you go, the more bizarre it gets.
* BlackAndGreyMorality: No major character is perfectly morally upstanding in these movies. The "good guys" are very manipulative, deceptive, and arguably even downright [[GoodIsNotNice cruel]] at times in pursuit of their goals. Then there are the good guys' targets (or "bad guys" if you think they are bad enough to be distinguished from the "good" ones) who are considering maintaining a dangerous corporate monopoly, which is part of what drives the other side to resort to such ethically questionable methods in the first place.
* BlackBox: The PASIV. How it works is never really explained, aside from an large yellow button that needs to be pushed and the IV lines that go into the operator's arms.
* BlackScreenOfDeath: The ending, which never reveals [[spoiler:whether the top falls or not.]]
* BlankBook: The papers recovered from the safe that appear white.
* BlindAlley: Averted. Cobb runs down an alley to try and ditch several agents that are chasing him. They notice him stuck in between the two buildings at the other end of the narrowing alley and he barely escapes them.
* BloodFromTheMouth: [[spoiler:Saito]]. Justified, as he [[spoiler:[[YourMindMakesItReal is dying of a punctured lung in the dream]].]]
* BloodlessCarnage: There is almost no blood at all in the entire movie. The notable exception is [[spoiler:Saito]], whose injury is a critical moment in the plot and for a fatal wound it's still just a very small hole that barely bleeds. In the snow level [[spoiler:Fischer and Mal]] get shot, but show only a small red dot on their white jackets to show that they have been hit. Like so many other tropes, justified by the fact that most if not all characters never were in actual firefights and would only know them from movies, so that's how they'd expect gunshot wounds look.
* BobFromAccounting: Cobb introduces himself this way when setting up the Mr. Charles gambit.
* BollywoodNerd: Yusuf. A cool nerd, though, and one who can handle himself in the heat of action, which is key considering his dream is the top layer.
* BondOpeningSequence: The action-packed opener, in which it's left to the audience to deduce what's going on.
* BookEnds: The final scene with [[spoiler:Saito as an old man]]. Indeed, this scene makes absolutely no sense when it is first shown in the film, and it is only at the end that we understand.
* BrainwashedAndCrazy:
** Mal -- brainwashed in that [[spoiler:Dom's inception in her mind of the idea "your world is just a dream" could reasonably be considered brainwashing]], and crazy in that [[spoiler:though she may be technically sane as a living person, Dom's subconscious version of her is just wacked out]].
** She's crazy as a living person too: [[spoiler: because of the brainwashing, she thinks that she's still living in the dream, and then intends to kill herself and Dom to get back to the "real world". She goes to such lengths as to get herself declared sane and him abusive so that he'll be arrested and kept away from his own children, all in order to make sure he kills himself too]].
* BrainyBrunette: Ariadne. And, in the past, [[spoiler:Mal]].
* ButHeSoundsHandsome: Saito sees Browning, who he assumes to be Eames in disguise. He walks right up to him and says, "I see you've changed." Browning gives him an odd look and Saito sees Eames behind him. Saito quickly says, "I mistook you for a friend of mine." Browning smirks and says, "Must be a good-looking fella."
* ButtMonkey: Poor Arthur. Especially when it comes to testing out the "kicks", somehow Arthur's always the one getting his chair knocked over, his gun dissed by Eames, and so on. His awesomeness at the end makes up for it, though.
** It helps that he is [[FanPreferredCouple clearly]] [[YaoiFangirl sleeping with]] [[BelligerentSexualTension Eames]].
** Not to mention he gets shot twice at the beginning. Once just to cause him pain, and once BY HIS OWN TEAMMATE (admittedly to wake him up).
* TheCaper: You could say that again. Inside the world of your subconscious. Played with in the beginning of the movie and later as the group is attempting to place something ''in'' Robert Fischer's head, rather than take something ''out'' as was the case with Saito.
* CaperCrew: Can't have a caper without one.
* CaptainObvious: At the end, right after the first kick :
-->'''Eames:''' Cobb ? Did we miss it ?
-->'''Cobb:''' [''who just saw the huge avalanche, as did everyone''] Yeah, we missed it.
* CarChase: Fischer's projections chasing Yusuf's van in the first dream layer.
* CoolGun: So many to list. Highlights include Eames Milkor MGL grenade launcher, Arthur's FN SCAR assault rfile and Cobb's suppressed Beretta PX4 Storm handgun.
* CasualDangerDialogue: Saito intervenes as Dom is being chased by Cobol assassins, knocking out Dom's last tail with a ToyotaTripwire then quipping, "Care for a lift, Mr. Cobb?"
* ChekhovsGun:
** The top comes back with a vengeance, and the train makes a few appearances before it gets any context.
** [[spoiler:The Penrose stairs.]]
** The [[spoiler:dollhouse]] is pictured very briefly near the beginning and turns out to be [[spoiler:where Cobb planted the inception in his wife's mind.]]
** Cobb mentions early on that he doesn't like trains. [[spoiler:Ariadne also briefly sees a freight train in his memory. In the first level of the inception job, Cobb's subconscious rams them with a freight train. Turns out it's the train he and Mal killed themselves with to get out of Limbo.]]
** The large butcher knife Mal is seen fiddling with.
** A literal one. Cobb's Beretta PX4 Storm handgun which he dramatically loads in the elevator up to Mal. Ariadne gets a hold of it and uses it to kill Mal once and for all.
** Subconscious security. In Cobb's first interaction with Saito, he mentions being able to teach his mind to protect itself from Extraction. This comes back to bite them in the ass when they try to pull the job on Fischer [[spoiler:but not when Cobb has to retrieve Saito from limbo later, because this time his subconscious knows Cobb is doing the best thing for him]].
** The picture of Robert playing with his pinwheel.
** A lot of the tricks of the trade of extracting show up in the earliest scenes of the movie way before they are explained - the kick, using music to time waking up, [[spoiler:having a dream within a dream]], etc.
* ChekhovsSkill: [[spoiler:Arthur demonstrates to Ariadne [[{{Bizarrchitecture}} paradoxical architecture]], namely the Penrose steps, and then uses it himself to get behind someone who is chasing him down a stairwell.]]
* ChessMotifs: Ariadne handcrafts her totem into a Bishop chess piece.
* ClapYourHandsIfYouBelieve: Dreamers when inside the dreamworld have this power. While you can literally do just about anything, doing so to someone else's dream is a VERY BAD idea since the more you mess with their dream the more likely their projections will catch on to the dreamer and force them out.
* ClearMyName: This is Cobb's motivation for most of the film.
* CloseOnTitle: The movie doesn't have a title card until the end credits. [[DepartmentOfRedundancyDepartment Where it is displayed three separate times.]]
* ColdSniper: When the team enters the third level, Cobb is equipped with a sniper rifle and shoots several mooks to clear the way to the fortress. Subverted in that [[spoiler: he's unable to bring himself to shoot Mal, who then shoots Fischer.]]
* ColourCodedForYourConvenience: In the snow level of the dream, Cobb's crew carry guns and/or wear goggles that have all been colored white, and the mooks defending the fortress cover their faces in black while carrying black guns without winterized camouflage. Helpful since everyone is wearing winter combat gear and would be otherwise indistinguishable. Possible JustifiedTrope: [[spoiler:Eames]] may have made this adjustment as the dreamer for the snow level, or [[spoiler:Fischer]] may be influencing the projections because [[spoiler:the Mister Charles gambit worked and he wants the Inception team to win.]]
** The dream layers are also tinted differently to help the viewer discern between the switching scenes. The top dream layer is blue, the second is brown and the final dream level is white.
* ComeWithMeIfYouWantToLive: Saito does this to Dom. In a subversion, Dom (as Mr. Charles) does it to Fischer, albeit it's "if you want your secrets kept safe."
* TheConstant: Played straight with the "totems." Inverted with everything else in the world around them. Furthermore, if you believe the entire film was a dream [[spoiler:the totems have no meaning, and everything is nonconstant.]]
* ConvenientlyTimedAttackFromBehind: When Mal tries to attack Cobb with a knife in the last level, [[spoiler: Ariadne shoots her from behind him.]]
* TheConWithinACon: Well, if you view "incepting" and "extracting" as cons then Fischer is basically conned by being tricked into attempting to extract information from Browning.
* CoolCar: The Hummer with treads used by the guards of the snow fortress.
* CoolTrain: The Shinkansen at the beginning and (for fans of American freight trains) the train from Cobb's dreams.
* CorruptCorporateExecutive: While most examples are villains, Saito is a rare anti-heroic version of this trope. He is willing those who try to steal from him, hires Cobb's crew to MindRape a rival, and can undo a murder charge with a single phone call. However, [[IGaveMyWord he also honors the agreement]] he makes with Cobb.
* CorruptTheCutie: Ariadne. Michael Caine's character even refers to Cobb as wanting to "corrupt" one of his best students. Cobb openly tells her the job is not legal, but he, Arthur, and Ariadne herself each admit that after tasting the power of dream architecture, she would never want to go back. She willingly joins the team.
* CrashingDreams: A dreamer getting wet, being physically jostled, etc. results directly in events occurring in their dreams (such as a sudden flood, or gravity ceasing to function normally) which reflect whatever their body is feeling.
* CrusadingWidower: Cobb, though rather than revenge he wants to reunite with his children.
* {{Cyberpunk}}: Actually done believably for once. See TwentyMinutesIntoTheFuture.
** More accurately, the movie is PostCyberpunk, lacking both the "cyber" and the "punk", while still being clearly a successor to the parent genre.
* {{Cyberspace}}: Subverted in that this movie hits every cyberspace trope it can ''without computers''.
* DarkAndTroubledPast: Cobb has some ''serious'' issues concerning his past which have a major impact on his ability to work. Not that he feels he has to be upfront about it to those endangered by it!
* DeadpanSnarker: Eames and Arthur, usually at each other, though Arthur tends to buckle down once the work starts.
* DeathIsCheap: Being killed in a dream merely leads to the subject waking up, although if it happens while they're sedated, it can lead to remaining in limbo for what feels like ''years'' (see AndIMustScream).
* {{Determinator}}: [[DeconstructedCharacterArchetype Deconstructed]]. [[spoiler:Quite literally, Cobb is his own worst enemy. The mental projection of his wife that hounds the protagonists is merely his dogged determination to keep his wife "alive" in some shape or form, to ease his own guilt over her death. Furthermore, Inception itself is revealed to be a brutal deconstruction of this. Once an idea is incepted, it defines the victim, making that single idea the one thing that they will never give up on, no matter what.]]
* DisproportionateRetribution: In a bizarre case of dream logic, [[MegaCorp Cobol Corp.]] sends ''assassins'' after the heroes the ''very minute'' they find out [[YouHaveFailedMe they've failed to infiltrate Saito's mind]], then sends two dozen more when the heroes are spotted in Kenya. This is somewhat less disproportionate if you take into account the prequel comic "The Cobol Job." The Arthur/Cobb/Nash team had failed to retrieve information on Proclus Global (Saito's company) ''twice'' by the start of the movie.
** Then again if [[AllJustADream it's just a dream]], Cobol Corp's assassins may be just projections.
** And, of course, extraction is technically industrial espionage, which is illegal. Getting rid of Cobb after Saito's rumbled him would prevent Saito from discovering who hired Cobb and having Cobol either sued or prosecuted.
** Extraction is particularly illegal after "what happened" (which isn't explicitly said to be related to [[spoiler:Cobb's previous inception]]).
* DissonantSerenity: Edith Piaf as background music during the fight sequences.
* DistractedFromDeath: In the third layer of Robert Fischer's dream, [[spoiler:he looks away from his dying father just long enough to open the safe and see the contents. He then turns back to find his father dead.]]
* DramaticGunCock: Early on, Mal has Arthur at gunpoint and pulls the cock to make Cobb confess.
* DreamApocalypse: There are two or three variations: To a lesser extent, the projections who attack any foreign entity in the dream when the host starts to realise he's dreaming; played much straighter, however, is [[spoiler: Cobb's projection of Mal, particularly at the end within limbo]] and inverted with [[spoiler: the real Mal, who was convinced that what Cobb thinks is the real world is a dream, and that she needed to die to return to "reality."]]
* DreamLand: Basically almost the entire setting for this movie, or even [[OrWasItADream all of it]].
* DreamWeaver: Extraction/inception teams, and architects in particular, are a sci-fi variant.
* DreamWithinADream: The dream-share can be used to [[RecursiveReality create deeper-level dreams within the dream]].
* DrivenToSuicide: [[spoiler:Mal Cobb]]. Subverted several times when characters resort to "suicide" as an emergency measure to escape from the dream state.
* EarnYourHappyEnding: For Cobb.
* EldritchLocation: The dreams, especially the second dream Ariadne entered where she plays with the laws of physics there by tilting a portion of the town and messed up the gravity. Cobb's deepest dream level also qualifies here.
* TheEndingChangesEverything: [[spoiler: [[EpilepticTrees It's entirely plausible]] that almost all of the events in the film actually take place in one character or other's dream.]]
* EnemyWithin: Mal, or more accurately Cobb's projection of his guilt from [[spoiler:injecting an idea into Mal's mind that ended up driving her to kill herself in Limbo to return to reality, only to believe that reality was just another dream and kill herself again.]]
* EpicMovie: An all-star cast. Years and years in the making. Large nonuple-digit budget. From the director of ''Film/TheDarkKnight''. This fits the trope to a T.
* EpiphanyTherapy: [[spoiler:At the climax of the film, Cobb finally summons up the courage to confront his projection of Mal and accept the fact that she is dead.]]
* EveryoneLives: A ForegoneConclusion, since it's all a dream. But dying isn't really [[FateWorseThanDeath what they're afraid of.]]
* EverythingsBetterWithSpinning:
** Cobb's spinning top.
** Possibly the single most awesome fight scene ever to appear in anything ever, when Arthur takes on the man in the spinning ''corridor''. Made even cooler with little CG necessary for said fight. The hallway was a giant rotating set, and Joseph Gordon-Levitt did all of his own stunts in the sequence.
* EverythingTryingToKillYou: If you meddle with someone's dream too much, all the nice not-real people (and architecture) start getting feral. And they always know who's doing it. And sometimes, [[spoiler:what's effectively [[SilentHill Pyramid Head]] finds her way in.]]
* ExcuseMeComingThrough: Multiple times during the chase scene in Mombasa.
* ExoticBackdropSetting: Mombassa. There are no named Kenyans.
* TheFaceless: Cobb's kids. Justified, since they are the projection of Cobb's memory -- specifically, his last memory of them, when they didn't turn around to look at him. He vehemently refuses to make them turn around in the dreams, because when he sees his children again he wants it to be for real. [[spoiler:In the end, Cobb finally sees his children's faces. [[MindScrew Or does he?]]]]
* FakeoutMakeout: Arthur asks Ariadne to kiss him to keep Fischer's subconscious from detecting them.
-->'''Ariadne:''' They're still looking at us.\\
'''Arthur:''' [[UnresolvedSexualTension Yeah, it was worth a shot]].
* FateWorseThanDeath: Limbo. It's an unformed dream state where you go if you die in a dream but are too sedated to just wake up. The time dilation is so pronounced that a few minutes of real time is experienced as hundreds, if not thousands, of years. You're going to be there for a ''very long time''. If you've got 30 minutes to go before your kick hits, or if you've missed the kick and are gonna be under for hours until the sedative runs out you'll be in limbo for an effective ''eternity''. [[spoiler:And then subverted when it's shown you're also effectively God there. So no, it isn't that bad.]]
** As noted in AndIMustScream, [[spoiler:the bigger problem is returning to the real world and then discovering you've become addicted to the "omnipotence" of Limbo...]]
* {{Fauxshadow}}:
** Ariadne's and Arthur's totems.
** The insane time dilation as they go further down, such as the third level experiencing 400x the time of the first level. [[spoiler:They spend maybe a few hours at each level.]]
* FilmNoir: Creator/ChristopherNolan has effectively mixed [[IncrediblyLamePun Noir chocolate]] with CyberPunk peanut butter, and it's as tasty as it sounds.
* FireForgedFriends: By the time [[spoiler:he rescues him from Limbo]], Cobb and Saito seem to share a deep bond and trust.
* FlippingTheBird: Done by Yusuf to a projection when he sets off the kick in Fischer's first dream layer.
* FollowTheLeader: Not the movie itself, but the advertising: it's become increasingly common for movie trailers to use the same '''''[[MemeticMutation BWOOOONNNG]]''''' sound effect used in ''Inception'''s teaser.
* {{Foreshadowing}}:
** An interesting variation, as most examples feature characters discussing events they already know about, but the audience does not; the characters may be [[CallBack calling back]] to an event in the chronological past we have yet to see, or predicting the future using information we have yet to learn.
** An example calling back to the characters' past: Mal asks Cobb in one of the first scenes whether she will [[spoiler:die from jumping off the building. She had committed suicide already by this point, and this is Cobb's projection of her haunting him. If you look at the room behind her on the ledge, it's ''identical'' to the one he's in, but you might not notice if you were focused on the characters.]]
** An example of a conversation that does foreshadow future events, but which the audience does not know what they are speaking about (in this case, [[spoiler:Cobb's projections of Mal sabotaging the mission]]):
-->'''Arthur:''' And you. What the hell was that?\\
'''Cobb:''' I have it under control.\\
'''Arthur:''' I'd hate to see out of control.
** Fischer says to Saito after the avalanche "Couldn't someone have dreamed up a goddamn beach?" Later, [[spoiler:he dies and goes to limbo which starts on beach.]])
** In Ariadne and Cobb's second session, Cobb's subconscious starts to get aggressive:
--->'''Ariadne:''' Mind asking your subconscious to take it easy?\\
'''Cobb:''' I can't, it's my subconscious.
*** Taken into context with Mal and Cobb's repeated projections of her that's revealed later, this line suddenly takes on a whole new meaning.
** In the beginning after Cobb wakes up he mutters:
--->I hate trains.
* FromBadToWorse: Mal [[spoiler:infests Cobb's brain]] to the point where he can barely focus on the mission. The team's employer [[spoiler:gets shot and ends up on the verge of death]]. Then of course there's the ending, which may or may not be this trope. And pretty much [[HolyShitQuotient everything in between]].
* GenreBusting: FilmNoir meets TheCaper with a dose of PostCyberpunk.
* GenreThrowback: To 90's {{Cyberpunk}}/ PostCyberpunk movies that had the PlatonicCave idea and {{Cyberspace}}. Similar to movies like: ''Film/TheMatrix'', ''TheThirteenthFloor'', ''StrangeDays'' and ''{{Film/eXistenZ}}''.
* AGlitchInTheMatrix: The movie [[IncrediblyLamePun spins]] on it. With what the individual weirdness of dreams, and the weaponized one that is the top.
* AGodAmI[=/=]RealityWarper: Ariadne enjoys herself too much while learning what it means to be an architect. Arthur is also no slacker when it comes to warping reality, and he even manages to turn recursive, impossible geometry back on his opponents.
* GoneHorriblyRight: [[spoiler:Cobb's first inception.]]
* GravityScrew: The entire hotel corridor fight sequence between Arthur and the projections. There's also Cobb and Ariadne walking straight up a wall in the "Paris folding" sequence.
* GreyAndGreyMorality: On one hand, they ''are'' essentially {{brainwashing}} their target on behalf of a business rival. On the other hand, they ''are'' helping the guy get over his deep-seated father issues and getting him to forge his own path. They're also stopping him from creating a dangerous energy monopoly.
* GrowOldWithMe: Part of Mal's anger with Cobb stems from his promise that they'd do this. [[spoiler:They did in 50 years of Limbo.]]
* GuileHero[=/=]ManipulativeBastard: Eames, who specializes in manipulating the emotions of marks by impersonating people close to them in their dreams, is one or the other.
* GunsDoNotWorkThatWay: One of the first clues that the prologue is a dream sequence (aside from being set in a massive Japanese castle) is a gun working in a way it should not.
[[/folder]]

[[folder:H-M]]
* {{Hammerspace}}:
** Sometimes, the ordnance TheTeam needs will simply ''be there'', and will frequently appear just out of the viewers' field of view. {{Lampshade|Hanging}}d by Eames during the grenade launcher scene.
** Near the end of the film Eames manages to pull a copy of the PASIV, about the size and shape of a metal briefcase, out of a tiny first-aid-kit.
* HandWave:
** Many when it comes to the AppliedPhlebotinum that drives the plot. For example, making the dreams mostly realistic instead of bizarre abstractions.
** The "characters" do it all the damn time, as per RealLife lucid dreaming. Except as they're doing it to ''other'' people's dreams, the more they do it, the more likely that "projections" who populate the dream will notice the discrepancies, then hunt down and kill the intruding dreamer.
* HauntedTechnology: The projections within dreams, including Mal.
* HoistByHisOwnPetard: In the third dream level, Eames gets his gun knocked over a railing by a projection. The same projection then throws Eames over the railing. This allows Eames to retrieve his gun and shoot the projection.
* HollywoodSilencer: Used in the beginning. Oddly enough, it's paired with fairly realistic stealth techniques -- catching the bullet casing and gently placing the body on the ground as not to make too much noise. Possibly justified by the action taking place in a designed dream.
* HonorBeforeReason: When Saito is shot in the first layer of the dream and Cobb explains about the consequences of the sedative and how death will send the dreamer to limbo until he wakes up, Saito tells Cobb that he will still follow through on his promise to Cobb. [[spoiler:Cut to the end and Saito has died within the dream and has gone into Limbo and Cobb goes in to get him out. After they wake up, Saito who would understandably be shaken after having spent decades in Limbo having all but forgotten everything about himself until Cobb jolted his memory, takes one quick look at Cobb and reaches for the phone and starts dialing, indicating that holding to his promise was the first thing on his mind when he woke up.]] Saito is Japanese right? So honor would be incredibly important culturally speaking.
* HostageForMacguffin: In the first dream operation, [[spoiler:Arthur]] is captured--apparently by [[spoiler:Mal]]--and held at gunpoint in an attempt to [[PutDownYourGunAndStepAway force Cobb to give up]] [[spoiler:[[MacGuffin Saito's secrets]].]]
* HowWeGotHere: [[spoiler:The story opens InMediasRes with Cobb going to retrieve Saito from the dream that the latter is trapped in at the end of the movie.]]
* HumanoidAbomination: Mal is a [[{{Yandere}} psychotic]], [[AxCrazy deadly]], [[BackFromTheDead unkillable]], [[{{Determinator}} relentless]] enemy that exists inside of the protagonist's [[EnemyWithin mind]]. What horrendous form does this monster take? [[EveryoneLooksSexierIfFrench A French]] [[EvilIsSexy woman]]. *''shudder''*
* HypocriticalHumor: Arthur dryly points out how often Dom does things he tells everyone else not to do.
* IDidWhatIHadToDo: Cobb's justification for everything throughout the film, from his illegal activities, to deceiving his crewmates, to incepting Fischer [[spoiler:and doing the same to his wife]]. Usually in these ExactWords.
* ImperialStormtrooperMarksmanshipAcademy: All over the place. A nasty {{subver|ted trope}}sion occurs in the first dream level (the rainy city). Apparently in the world of ''Inception'', executives and other people with secrets to guard can receive dream security training -- Cobb poses as such a trainer early in the movie. Fischer has apparently had it, and as such has military projections who can shoot quite straight. They [[spoiler:fatally wound Saito]] and send the entire team scrambling.\\
\\
However, the {{mooks}} from the corporation who hunt Cobb and Arthur in what is allegedly the real world absolutely live by this trope. Two of them are equipped with semi-auto handguns and can't hit Cobb while he is running just few feet from them in the alleyway in Mombasa.
* ImplacableMan: Mal. Absolutely relentless and nearly impossible to reason with. Even if you're a trained dream infiltrator, when she shows up it's time to panic.
* ImpossibleMission: Though it's a very original variation on it, the film basically uses this standard plotline beat-for-beat.
* ImprobableAimingSkills: Played straight-ish. Cobb's crew can fire from uncomfortable positions and awkward locations and still drop plenty of mooks... in dreams, where they can also produce grenade launchers out of thin air. It's possible their aiming skills have more to do with skill at dream-manipulation and preconceptions as to how hard it is to hit a target than actual ability with firearms. Something similar probably explains how the basement-dwelling chemist is adept at driving in a high-speed chase through a crowded, rainy city, and how the crew happens to be skilled at rappelling down an icy mountainside.
* ImprovisedWeapon: When the variable-gravity fight moves into the hotel room, Arthur clocks his opponent with the room's phone.
* InMediasRes:
** It's made more relevant by dialogue about how no one ever remembers how they got somewhere in a dream, they just start in the middle of things.
** Most scene transitions throughout the movie do this, emphasizing that aspect. [[spoiler:This creates the impression the "real world" may be a dream too.]]
* InsanityDefense: Inverted. [[spoiler:Mal]] had herself declared sane by three different psychiatrists, so as to prevent [[spoiler:Cobb]] from being able to explain the nature of her madness, as part of her plan.
* InstantCostumeChange: With switching between layers of dreams.
** One at the end of the film during a panning shot of Robert Fischer. He's talking about the {{Aesop}} he's learned to "Browning" (Eames-in-disguise), whose form is briefly blocked from view by Fischer's body. On one side it's Browning; on the other, it's Eames.
* InstantDeathBullet:
** The mooks tend to die this way.
** When Mal [[spoiler:shoots Fischer in the snow fortress.]]
** Following that, when [[spoiler:Cobb shoots Mal in what appears to be her shoulder.]]
** Averted with [[spoiler:Saito]], who spends roughly a third of the movie with a fatal gunshot wound, and [[spoiler:Mal, in the final dream level after Ariadne shoots her.]]
* InternetBacklash: Not so much the film itself, but the ending [[http://www.collegehumor.com/video:1939234 got its share.]]
* IronicEcho: No room for tourists.
* JourneyToTheCenterOfTheMind: Taken in the most literal way imaginable.
* JustInTime: Everything, thanks to YearInsideHourOutside and it being a [[TheCaper heist]], albeit a darker version than most where YourMindMakesItReal.
* KansasCityShuffle: The Mr. Charles Gambit.
* KillItWithFire: The grenade launcher scene.
* LivingMacGuffin: Fischer is an interesting variant in that he is living but it is his ''projection'' that is more relevant.
* TheLoad: Saito. Eames warns him that a shared dream is no place for "tourists." [[spoiler:He becomes a literal load in the first dream stage when he's shot and has to be carried around, although he gets better from the second stage on.]]
* LotusEaterMachine:
** Yusuf runs one of these as a day job.
** The deep levels of the subconscious, especially being no easy way to wake up.
** Cobb warns Ariadne against constructing her dream world out of real life memories, lest it becomes this. [[spoiler:And then he proceeds to completely ignore his own advice. He should know -- that's exactly what happened to his wife. He was only able to pull her out by implanting the idea in her mind that her world was AllJustADream, and getting her to kill herself with him so that they could wake up. It worked, but the idea stayed in her mind, and she started thinking that the ''real'' world was a LotusEaterMachine as well.]]
* LoveMakesYouCrazy: [[spoiler:Mal. After she died, Cobb inherited a dose of crazy.]]
* LoveMakesYouEvil: Played with interestingly. [[spoiler:Cobb's love for Mal prompted him to MindRape her in order to get her out of Limbo. In turn, the brainwashed Mal ruined Cobb's life to make sure he would commit suicide with her. Cobb then knowingly risked the lives of his crew by trying to keep Mal alive in his dreams, whereupon she constantly sabotaged his jobs and attempted to kill his comrades so that he would join her in Limbo.]] You follow all that?
* MagicAIsMagicA: The rules of the dream world and extraction are continually elaborated upon throughout the movie; the movie makes more sense when you take notes.
** While the protagonists can alter dreams however they wish, in order to successfully steal or plant information they have to keep attention away from themselves long enough to do so. That means limiting in-dream special effects to subtle paradox trickery and convenient firearms, a la ''TabletopGame/MageTheAscension''[=/=]''TabletopGame/MageTheAwakening''.
* MagicIsAMonsterMagnet: Changing dreams too much causes projections to attack you like anti-bodies.
* MalevolentMaskedMen: Cobb's team don ski masks while pretending to be violent kidnappers interrogating Fischer Jr. in his dream.
* MasterOfDisguise: Eames, who can take on any form within a dream.
* MeaningfulEcho:
** Dom's repetition of Saito's words about dying alone as an old man, filled with regret.
** The entire ''You're waiting for a train'' speech given by Mal [[spoiler:was [[OnceMoreWithClarity originally said by Cobb]], when he and Mal were stuck in Limbo. He says this as they lay their heads on a railroad track, so a train could run over their heads]] to wake themselves up.
* MeaningfulName:
** "Cobb" means "dream" in Sanskrit, Hindi, Urdu, and Punjabi. It was also the name of a gentleman thief in ''{{Following}}'', Nolan's first feature film.
*** The proper pronunciation is 'khwaab', not 'cobb'.
*** It's also an old English word for "spider" (hence the word "cobweb"). Fitting, for a man who weaves webs and traps others in them. [[spoiler:And who, depending on how you look at it, may have indirectly killed his own mate.]]
** "Ariadne" is a very unusual name these days, but an appropriate one for [[GreekMythology a woman who leads a man around a maze]].
** "Mal" is a word in French, Spanish, Portuguese and other Romance languages, which can be used in different contexts to mean "bad", "evil", "hurt", "pain" or "sick".
** Yusuf is the Arabic variant of Joseph (the one who famously interpreted Pharaoh's dreams in Literature/TheBible).
** "Eames" is the last name of architects and designers [[http://en.wikipedia.org/wiki/Charles_and_Ray_Eames Charles and Ray Eames]].
** Fischer's name may be a reference to the Arthurian legend of the FisherKing, whose kingdom physically changes to parallel his wounds and suffering; this is appropriate given that much of the film takes place within his troubled mental landscape. Also, Robert "Bobby" Fischer is the name of one of the most famous chess players in history.
* MegaCorp: Cobol Engineering is Absurdly Powerful. They have dozens of assassins in, say, Kenya, waiting to be activated in a strangely dream-like plot development (though we are warned beforehand that Cobol operates heavily there). See Disproportionate Retribution.
** Even more powerful are Proclus Global - Saito's corporation whom Cobol was trying to steal secrets from - and Fischer-Morrow, who will have a monopoly on the majority of the world's energy concerns if Fischer Jr. decides to continue the empire instead of dissolving it.
* MementoMacGuffin:
** Cobb's totem, the spinning top, which was actually [[spoiler:Mal's totem before she died.]]
** Also, the picture of Fischer Jr. as a kid with his father as well as the pinwheel in said picture.
* MentalStory: Almost the entire film is set in ''someone'''s head.
* MentalWorld: One after another.
* MercyKill: There's a non-fatal version in the introductory sequence.
* MetaTwist: [[spoiler:Given the circumstances or their arrangement, a GenreSavvy viewer might expect Saito to try to screw Cobb over on their deal by the end. Theories on the ending aside, Saito appears to be on the level with Cobb and honors the deal.]]
** [[spoiler:Perhaps less so-- would you want to screw them over after what they just pulled off? Besides, Saito is the [[Film/TheLastSamurai Honorable Samurai.]] ]]
* MindRape: FromACertainPointOfView. [[spoiler:Cobb did it with the best of intentions, and it [[GoneHorriblyRight went horribly right]].]]
** This is basically the entire point of inception itself -- to plant an idea in someone's head that will consume them.
* MindScrew:
** Take notes. Better than most, due to MagicAIsMagicA. There are several different kinds.
** The most obvious mind-screw is keeping track of how many levels of dreams they take Fischer into. It's stated that beyond two is too unsafe to attempt, and three is what the characters are aiming for all along, but [[spoiler:they go into at least four. They go from the plane to a rainy city (first level) to a hotel (second level) to a snowy mountain fortress (third level) as planned, but when FromBadToWorse, they're forced to go into Cobb's crumbling wasteland (fourth level). And the beach where Cobb meets the aged Saito (may or may not be a fifth level). Alternately, the wasteland and the beach may not be "levels" at all - one or both may be limbo. And depending on your interpretation, there may even be some question as to whether the plane is "real" and not itself a level of another dream Cobb spends virtually the entire film in. One theory is that the film itself is a symbolic representation of the movie-going experience, essentially making the audience itself another "level" of the dream.]]
** The movie starts InMediasRes, as noted above, and most scenes do as well, jumping straight from one bit of dialogue or action to another without establishing shots of people introducing themselves, walking up the street, etc. Coupled with the observation that dreams often work that way, it forces viewers to question either the nature of the scenes in this movie that supposedly aren't dreams, or the nature of movies in general.
** [[spoiler:On two separate occasions]], Cobb doesn't check his top to see if it stops spinning. [[spoiler:The obvious one is at the end, when the movie ends and credit stops with the top wobbling but not actually fallen down. A more subtle example is right after Ariadne discovered Cobb's wife locked in his subconscious. He never checked that he was in reality when he started the whole heist mission.]]
** [[spoiler:When Cobb is in Mombasa, He goes under to test the new sedative. He is then interrupted by Saito after he "Wakes Up" from his dream. However, he drops his Totem, Picks it up, and Doesn't spin it afterwards. It's very possible that he could still be in that Basement.]]
** The whole thing becomes tragic considering that [[spoiler:it's possible for Cobb to have been guilty over nothing (and the entire 'heist' to have been pointless since Mal technically was never wrong about it all being a dream and them needing to wake up, and could possibly BE still alive.]]
** [[spoiler:Cobb ''always'' uses Mal's totem, and has been since he found it in their limbo dream. We never see what his was and Adriane was warned not to use another persons' totem or let them use yours (though this is probably to avoid them tricking you). It is possible that Mal was right and Cobb ''never'' woke up, but thinks he has because he is dependant on a totem that isn't really his.]]
* TheMirrorShowsYourTrueSelf: Within a dream, Eames can copy other people's appearances, but almost always has his own reflection. On one occasion he was, when in disguise, seated in front of multiple mirrors. Some reflected his true face, others reflected his disguise. Which mirrors reflected his true face and which reflected his disguise changed (almost certainly deliberately) between cuts.
** [[JustifiedTrope Possibly Justified]], since in an lucid dream, the reflection in a mirror is that of your self image.
* MiscarriageOfJustice: [[spoiler:Dom being charged with murdering his wife. [[FromACertainPointOfView Maybe]].]]
* {{Mooks}}: Plenty of mental-antibodies to oppose the heroes; Dream mooks are mookier than most mooks.
* MoreDakka: After Arthur's [[ImperialStormtrooperMarksmanshipAcademy firing proves ineffective]], Eames pulls out a grenade launcher to deal with the mooks.
-->'''Eames:''' You mustn't be afraid to dream a little bigger, darling.
** The [[GatlingGood machine guns]] on the jeeps in the third level seem to have BottomlessMagazines.
* MoreThanMindControl: In order for inception to work, it's necessary to manipulate the subject into finding the idea that is to be implanted emotionally appealing on a subconscious level - otherwise the mind will reject it.
* MortalWoundReveal: After the shootout/car chase in the first level, it's revealed that the only character who didn't escape unscathed was [[spoiler: Saito]].
* MrFanservice: At least half of the male cast counts, especially the guys in the inception crew. General consensus is that Arthur and Eames are particular favorites (helped by their choice of [[SharpDressedMan wardrobe]] and [[Creator/JosephGordonLevitt their]] [[TomHardy actors]]).
* TheMusical: Fan-made, but [[http://www.trebleentendre.com/ItM/index.html done]].
[[/folder]]

[[folder:N-S]]
* NinetyPercentOfYourBrain: Cobb tells Ariadne that when awake, people use only "a fraction" of their brains, but when sleeping, their whole subconscious is unlocked. This makes sense, to a degree. When you are conscious, immense resources are used to process sensory data. When dreaming these resources are known to be co-opted for other purposes.
* NaiveNewcomer: Ariadne, until she [[TookALevelInBadass takes a level in badass]].
* NamesToRunAwayFromReallyFast: Mal means "bad" or "evil" in many Latin-based languages.
* NarniaTime: Five minutes of real time is an hour in a dream (possibly more depending on the specific sedative that you use). This is compounded with each level of dream you go down.
* NeuroVault: A more metaphorical example. In the first dream layer, Browning suggests that Fischer Sr. may have subtly implanted the combination to his safe in his son's head in this way. Plus, according to the universe's rules, a person's subconscious mind often places hidden desires, secrets, etc. inside literal vaults in the person's dreams.
* NeverTrustATrailer:
** The early trailers seemed to imply that the "folding up a city block" thing would be much more crucial to the plot than what it was, basically a party trick. They also cut together dialog to use "inception" as the name for ''stealing'' an idea from a dream, but that is "extraction." "Inception" is the film's actual plot of ''planting'' an idea within a mind.
** Mal appears on the posters labeled as the FemmeFatale. The implication is that she's part of some rival organization working counter to our antiheroes. [[spoiler:In a sense, she ''is'' one of our heroes. Also, [[StealthPun she's dead]].]]
** Trailer three seems to indicate that Mal is Cobb's wife, and is still waiting for him back at home. [[spoiler:Well, one out of two is right...]]
** Saito was advertised as the [[BigBad main bad guy]]. He really isn't. [[spoiler:In fact, there is no Big Bad at all. The closest people are Mal and Fischer's dad, and they're both dead before the real conflict starts.]]
** The trailer made the movie look like a lot more of a MindScrew than it actually was.
* NGOSuperpower: The protagonists are trying to stop Fischer's company from becoming this.
* NoodleIncident:
** Every aspect of the dream sharing technology is kept purposefully vague. There are [[http://www.youtube.com/watch?v=mEItJLwvsF0 a few interviews online]] that [[AllThereInTheManual set up the plot]]. Cobb's father-in-law is noted as the inventor of the technology. Apparently, the technology was outlawed or regulated some time ago because of some unspecified incident.
** Cobb references "The Stein Job", in which he had previously used the "Mr Charles" gambit. Arthur points out that it didn't work.
** There weren't a lot of legal opportunities for extraction after an incident which may have been [[spoiler:Cobb "killing" Mal]] or maybe something else entirely.
* NoOneGetsLeftBehind: Averted and played straight. [[spoiler:In the third layer, just before going into Limbo, Eames says that they're going to go once the kick comes, whether Cobb and Ariadne are back or not. A few moments later, Cobb stays in Limbo to find Saito.]]
* NoPronunciationGuide: Early on, people were pronouncing Saito's name as ''Say''-toe as opposed to ''Sigh''-toe. This changed later in the film. However, Arthur still messes it up in every line, putting this into SpellMyNameWithAnS territory.
* NotEvenBotheringWithTheAccent: Fischer Jr., who's supposed to be Australian (according to his passport), speaks with an American accent. Creator/CillianMurphy, the actor who plays Fischer Jr., is Irish in real life. It is possible that Fischer Jr. was raised in America, or that his mother was American, which would help explain, but none of these things is explicitly stated.
* TheNotLoveInterest: Ariadne to Cobb. She grows to understand him more than any of the other crew, and [[spoiler:is perhaps single-handedly responsible for saving his soul]]. At the same time, her concerns are more practical than romantic, [[spoiler:as Cobb was taking an ''enormous'' gamble with everyone's lives.]]
* NotMyDriver: In the first dream level, the protagonists kidnap Fischer this way. Possibly justified in that they designed the place, so they could make sure theirs was the only cab available.
* NotSoSimilar: What allows our protagonist to finally overcome the figure in his head that's trying to kill him, is realizing it isn't the person it appears to be and confronting it over the issue.
* OhCrap: Cobb's expression in the 2nd dream-state when he hears broken glass [[spoiler:which brings to his mind the night Mal killed herself]] which results in [[spoiler:the projection of his children showing up]] during the Mr. Charles gambit.
* OlderThanTheyLook: [[spoiler:Both Cobb and Mal were in Limbo for around 50 years, making them mentally in their late 70s to early 80s. Saito too. And, depending on how long Cobb was in Limbo hunting him, he may be north of a hundred by now.]]
** If you count the transpacific flight time, which is 10 hours real-time, [[spoiler:Cobb hunted Saito through Limbo no less than 9 and a half hours. Multiplied by 20, by 20, by 20 and by 20 again, it comes to a whopping 170+ years. So psychologically, at the end of the film, Cobb is at least 250 years old.]]
* OnceMoreWithClarity: The first scene of the movie.
* OneLastJob: Cobb tells Miles that Saito's job will be his last, and that he's only taking it on so that he can see his children again.
* OneManArmy: Although TheTeam as a whole is [[BadassCrew extremely badass]], the gold medal of badassery goes to Eames. [[spoiler:In the snow level, Eames distracts an entire scout team so that Saito and Fischer can infiltrate the stronghold. He then beats the scout team consisting of several snowmobiles and skiing mooks all by himself, steals one of their snowmobiles, and proceeds to destroy an entire convoy of a snow-Humvee and several skiing mooks by cutting the rope between the Humvee and the mooks with his snowmobile and blowing up the Humvee by throwing up a C4 into the turret-guy's hand. Moreover, when he told the injured Saito to look after Fischer, Eames went outside to the perimeter of the base, defended the base from a ton of Mooks while planting C4 in every pillar.]]
* OnlyAFleshWound: No characters show injury or bleeding from the blood vessels in their wrists. And at the beginning of the movie, one character yanks the tube off like it's not even sticking out of his body, going against the guidelines of the PASIV manual.
* TheOphelia: Mal's madness starts off Cobb's character arc.
* OpinionChangingDream: The title and concept of the movie involve attempting to engineer one of these in another person's mind (and without them realizing you've done it, to boot).
* [[OrdinaryHighSchoolStudent Ordinary College Student]]: Ariadne, while a skilled architectural student, and as we soon discover, an excellent and precocious architect of the mind, acts as our AudienceSurrogate during the planning of the mind-heist, [[TheEveryman as she is the only character unschooled in the ways of mind crime]]. She gets to ask questions about the rules of the dream world.
* OrpheanRescue: For those trapped in limbo.
* PaintingTheMedium: Cobb offers Ariadne a job, and they discuss it while walking through Paris, cutting between several locations. He then asks her how they got to the café they're sitting at. [[spoiler: She can't remember what's been happening during the "cuts" and realizes they're in a dream.]]
* PantsPositiveSafety: Cobb keeps a pistol in the waistband of his trousers, as seen in the beach scene.
* PermaStubble: Maybe it's Cobb's [[Film/TheMatrix residual self-image?]]
* PerpetualTourist: Eames appears to be playing this role at the beginning of the film.
* PerspectiveMagic:
** The [[http://www.wired.com/magazine/2010/08/the-never-ending-stories-inceptions-penrose-staircase/ Penrose Stairs]] work this way.
** In a meta example, a lot of the film's special effects were accomplished through perspective magic: the zero-gravity fight in the hotel corridor (using a rotating set) and the water meniscus levels going all weird (using a tilting set). Both times, the camera was level relative to the moving set.
* PinchMe: Averted. Even if you are aware you're in a dream, you can't leave it unless you're given a "kick" in the real world or if you die in the dream world. The very basis is averted too, as you can still feel pain in a dream. Extreme pain, as we learn early on.
* PinPullingTeeth: Saito does this during the final assault.
* PleaseWakeUp: Used multiple times, sometimes in the "dying" sense, sometimes in the "wake up from sleep" sense.
* PlotArmor: The team (and Fischer, to some extent) seem to be wearing this during the shootout in the rainy city. Their cab is riddled with bullet holes, all of the windows have been shot out, and yet only [[spoiler:Saito]] is hit--once. The car chase in the van [[spoiler:with the sleeping heroes]] is even more {{egregious}}.
* PosthumousCharacter: [[spoiler:Mal. Sort of. Maybe.]]
* PottyEmergency: Yusuf drank too much and then forgot to go to the bathroom before falling asleep, so in his dream, UsefulNotes/LosAngeles is rainy.
--->'''Eames:''' Too much free champagne before we went under, eh Yusuf?
--->'''Yusuf:''' Ha ha bloody ha.
* PowerPerversionPotential: The projections are one's subconscious. This could get really creepy, really fast.
** You can also change your appearance and gender in the dream, as demonstrated by Eames.
* PrecisionFStrike: After Arthur explains to her that you can't wake up unless you die in the dream, Ariadne mutters "What the fuck?".
* PreMortemOneLiner: Arthur says "Paradox" before pushing a mook off [[{{Bizarrchitecture}} the Penrose Stairs]].
* {{Prequel}}: "[[http://movies.yahoo.com/feature/inception-comic.html The Cobol Job]]", the story leading up to the events of the movie.
* PrettyLittleHeadshots: When Cobb shoots Arthur in the head at the start of the film so the latter can escape from the dream.
* ProperlyParanoid: All dream extractors keep a special "totem" with them that's supposed to help them determine whether they are in someone else's dream or not.
* PreviewsPulse: The most famous! [[http://www.youtube.com/watch?v=8hP9D6kZseM Its trailer featured a distinctive sound]] that [[MemeticMutation quickly became memetic]].
* PutDownYourGunAndStepAway: Played straight and then promptly subverted in the beginning. Cobb puts the gun down when Arthur is brought in at gun point, then makes a grab for the gun to snap Arthur out of the dream.
** During the early HostageSituation involving Arthur.
* [[spoiler: [[PsychoExGirlfriend Psycho Dead Wife]]: Mal.]]
* RaceAgainstTheClock: Played with; it's a race alright, but it's different clocks for different characters. Essentially, clocks within clocks within clocks: the "kicks" that wake people one stage closer to reality, but don't work more than one level deep.\\
\\
As each dream level has a timed kick, and time slows down further with each level downward, the twist is that if you don't make one kick, you're stuck having to possibly wait what feels like years in the lower level. Stuck there while [[EverythingTryingToKillYou everyone is trying to kill you]], as someone the level above you arranges another kick -- if they can do it before being taken by a higher kick themselves. Therefore, the reward the characters get for beating one clock? Beating several more clocks.
* RailroadTracksOfDoom: [[spoiler:Mal and Cobb get run over by a train in order to return to the real world.]]
* RareGuns: Being in a dream world where everything is possible, Arthur has no problem whipping out a SCAR-L, which in real life costs better than $2500, roughly $4000 with the scope, and is hard to find even if you can afford it. And then Eames upstages him with the revolving grenade launcher.
* RealityWarper: The whole point of having an Architect on the team (in this case, Ariadne).
* TheReasonYouSuckSpeech: [[spoiler:In the dream limbo, Cobb finally tells "Mal" that she doesn't have the perfections, imperfections, or complexity of his real wife and that she's just a '''shade''']]. [[BerserkButton She doesn't take that well.]]
* RecursiveReality: Recursive Simulacrum subtype, as well as, let's face it, every other mind screw trope. This is an interesting play on the MatrixHypothesis, since due to MagicAIsMagicA, for some reason the [[AppliedPhlebotinum chemical cocktail]] works the ''same inside every level'' of the dream, presumably because YourMindMakesItReal. Never has a more logical dream been dreamed; presumably Fischer has a very organized subconscious, while Cobb does not.
* RedOniBlueOni: Cobb and Arthur, respectively. Eames even refers to Arthur as a "stick in the mud" with "no imagination." Meanwhile, Cobb is much more intense and reckless.
* RedShirtArmy: The subconscious security... projections of Fischer's heavily self-guarded mind.
* RefusalOfTheCall: Ariadne tries this, but it doesn't last long.
* TheReliableOne: For all that Arthur "has no imagination", he's the best he is at what he does, which is making sure that you get out of any situation in one piece. Definitely the kind of guy you want watching your back.
* TheReveal: The cause of [[spoiler:Mal's death.]]
* RewardedAsATraitorDeserves: [[spoiler:Nash, the architect from the Cobol job.]]
* RiddleForTheAges: Whether or not Cobb is dreaming in the final scene.
* RuleOfSymbolism: [[TheoryOfNarrativeCausality With in-universe justification]], no less - that's how dreams work. For example; why is Fischer Sr. lying on a hospital bed inside a ''bank vault'' inside an ''Arctic fortress?'' Because he has a big secret, of course. Indeed, for a typical extraction, the architect will place a vault in the environment. The dreamer's subconscious will instinctively hide all important/secret information there. Then you just need a good team to extract it. Think of the other things can be added to the environment to aid or hinder a heist and it's easy to see why Nolan thinks the movie has potential as a game.
* SacrificialLamb: Nash, Cobb's previous architect.
* ScareChord: When [[spoiler:Ariadne is looking into Cobb's dream and sees Mal in his "house." Mal suddenly looks up at her (and directly at the audience), and BAM! Out of your seat!]] In this case, the cause of the scare chord is [[spoiler:a cute french lady]], thus proving that this trope makes anything scary. Considering that this is [[AxCrazy Mal]] we're talking about here, and the wide-eyed look she gives Ariadne is [[spoiler:not ''surprised'' but '''murderous''']], the scare chord may not have been ''entirely'' necessary..
* SceneryGorn: Paris exploding near the beginning and the dream city collapsing into the sea near the end.
* SceneryPorn: Near on everywhere. Tokyo, Paris, the snow fortress, the final dream city...
* TheSchlubPubSeductionDeduction: In the second dream level, Eames poses as a [[HelloNurse gorgeous blonde]] and hits on Fischer in order to distract him while he steals his wallet - and in order to make Fischer [[TheChessmaster more]] [[MoreThanMindControl trusting]] of Cobb's "Mr. Charles" gambit.
* SchrodingersButterfly: The characters take great pains to avert this. The ending takes great pains to leave it ambiguous.
* ScrewTheRulesIHaveMoney: Saito is rich/powerful enough to [[spoiler:clear Cobb of his murder charge with a single phone call.]] Then there was this priceless moment when TheTeam is discussing how to be left alone with Fischer for ten hours during a flight...
-->'''Arthur:''' But you'd have to buy out the entire cabin. And the first class flight crew.\\
'''Saito:''' I bought the airline.\\
''[Everyone looks at him incredulously]''\\
'''Saito:''' ''[awkward]'' [[CrowningMomentOfFunny It seemed neater]].
* SecretTest: Saito's test of skill, which the team (and Cobol) mistook for a job. In level 2, they succeed in getting the documents (though key info is blacked out), but fail in Saito's eyes because the deception was obvious (or so he thought at the time). In level 1, they fail because of the carpet mix-up, but succeeded in impressing Saito.
* SherlockScan: Saito figures out that the ActionPrologue is a DreamWithinADream -- ''not'' because of the explosions happening everywhere, but because ''the shag carpet on the floor of his girlfriend's apartment is polyester, not genuine wool''. Saito is definitely earning his salary as TheChessmaster.
* ShipTease: A small one between Ariadne and Arthur after the [[CrowningMomentOfFunny rather humorous]] FakeoutMakeout.
* ShootTheMoney: Did they ever. Filming took place in six different countries, and the filmmakers made sure to make creative use of the exotic scenery. They don't just show you downtown Paris -- ''they fold it on top of itself''. They don't just set a few scenes in an ancient Japanese castle -- ''they flood it, and then blow it up''. And so on.
* ShoutOut: Has its [[ShoutOut/{{Inception}} own page]].
* SirNotAppearingInThisTrailer: Yusuf, despite being a key player in the dreamscape, doesn't appear much in the promotional material, certainly not as much as the big stars. Mal isn't in much of the trailers either, though she does make it to the posters. In fact, on the main theatrical release poster that shows the entire team, Yusuf is pictured despite the fact his actor isn't among the [[AllStarCast sizeable billing list of actors]]; even Pete Postlethwaite and Tom Berenger receive a mention in the billing despite appearing just a few minutes apiece in the film, but poor Dileep Rao is left out...
** On a positive note, his is one of only three actors names to appear on the Netflix envelope for the movie.
* SixthRanger: Saito, as well as Ariadne. [[spoiler:And, in one of the best {{Batman Gambit}}s ever, Fischer himself.]]
* TheSlowPath: Cobb and Saito being trapped in limbo state.
* SmartPeoplePlayChess: There are several [[ChessMotif chess references]] in the film, including Ariadne's totem (which is a bishop), the black-and-white tiled floor of the fortress, and the character name Robert Fischer, after Bobby Fischer.
* TheSmurfettePrinciple: The crew consists of around six guys and one girl. There is one other important female character, and [[spoiler:for most of the film, she's a projection of the main (male) character's subconscious.]]
* SoMuchForStealth: What happens if you tip off the "projections" to your presence.
* SoundtrackDissonance: ''Je ne regrette rien''. The rather upbeat melody already fits the trope to a T, but for added bonus, [[BilingualBonus the title means "I regret nothing", and the lyrics are about starting a new life without any remorse or remaining attachment to the past]], in a film where the struggle against remorse and regrets is a major narrative theme.
** In addition, the Epic music for the later parts of the movie are just ''Je ne regrette rien'' slowed down substantially, as it could be expected to be heard by the crew while several layers down from the source of the music.
* SpannerInTheWorks: Cobb's projection of Mal in the extraction at the beginning and [[spoiler:almost again later when she kills Fischer in the snow level. It takes Cobb and Ariadne going into limbo to retrieve him to save the mission.]]
* SpiritualSuccessor: WordOfGod says this movie is Nolan's homage to ''Film/DarkCity''. He came up with the idea for it after seeing that film, which is the [[OlderThanTheyThink lesser-known]] [[DuelingShows rival]] to ''Film/TheMatrix''. It then spent ten years in development while Nolan wanted experience working on big-budget films. Meaning that ''Film/TheDarkKnight'' was a '''warm-up'''.
* SpottingTheThread: In the prologue, [[spoiler:Saito figures out that he's still dreaming by recognizing that the carpet in his love nest is inauthentic. So it's not so much spotting the thread as spotting the thread count.]]
* StealthPun: They spend much of the movie talk about "training your subconscious" ... and then they bring in an actual train.
* StormingTheCastle: The fortress assault.

[[folder:T-Z]]
* {{Tagline}}:
** "''Your mind is the scene of the crime''."
** "''The dream is real''."
* TakeOurWordForIt: The "horrific" ramifications of Limbo. Once it's introduced, Limbo is sold as a FateWorseThanDeath; a place one's mind will be trapped for eons until it turns into "scrambled egg." Despite this we never get to see the full extent of this. Of the five characters who go there, the one who went the most insane [[spoiler:(Mal) got that way because she was incepted.]] Cobb, [[spoiler:the next most problematic, only got that way because he incepted Mal and drove her crazy.]] Saito [[spoiler:becomes an old man, but Cobb rescues him before any lasting damage (seemingly) occurs.]] Ariadne and Fischer both get out pretty quickly and with seemingly little consequences. The implication is that Limbo itself doesn't drive you crazy, it's just that unless you know and are willing to take [[DrivenToSuicide the way out]], you'll be there for a very, very, ''very'', long time.
* TalkingInYourDreams: Dreams are not only a way to communicate with other people, but also to steal or implant ideas.
* TheTeam: Extractions have to be done by a team because there are different roles involved.
** TheSmartGuy: Averted; there is no single smart person becaue everyone has to be smart to be in this business.
*** The Extractor: Dom [[TheLeader leads the operation]] and [[TheFace does the talking]]. He is the one pulling out information. In this case, the one planting it
*** The Chemist: Yusuf mixes the phlebotium that allows TheTeam to reach the third level
*** The Architect: Ariadne was recruited to construct the dreamworld that TheTeam would use.
*** The Forger: Eames has the ability to copy someone's appearance in a dream world. [[TheBigGuy He also has a grenade launcher.]]
*** The Point Man: Arthur is in charge of doing the research and he's smart enough to figure out how to simulate falling in zero gravity.
*** The Tourist: Saito; yes even he counts because he's a CEO that twisted Cobb's arm into doing this in the first place
* ThanatosGambit: Mal [[spoiler:commits suicide, but makes it look like Cobb murdered her so he'll be compelled to do it with her or lose custody of the children. Of course, like the many characters who kill themselves in dreams in this movie, she doesn't believe she's really dying.]]
* TheoryOfNarrativeCausality: Dreams.
* ThereIsNoKillLikeOverkill: A rare nonviolent example.
--> '''Arthur:''' But you'd have to buy out the entire cabin [of a 747]. And the first class flight attendant...
--> '''Saito:''' [[ScrewTheRulesIHaveMoney I bought the airline.]]
* ThreeActStructure: After the short HowWeGotHere and pretty much like most [[TheCaper heist movie]], you get the exposition of what Saito wants (later, what all main characters will come to want, except Fischer Jr.), then, starting at about 20 minutes, their plan and preparation to do it, and then, starting at about 1 hour, the execution of it. But even better, the execution itself has three acts, represented by the three levels of dreams. So it's a ThreeActStructure [[MemeticMutation within]] a ThreeActStructure !
* ThroughTheEyesOfMadness: Depending on your interpretation of the film.
* ThrowTheDogABone: Meta-example with one of the movie's costume designers and ''Michael Caine himself'' going on record to state that [[spoiler:the top falls over at the end.]]
* ToiletHumor: See PottyEmergency
* TokenGirl: Ariadne.
* TokenRomance: Surprisingly averted.
* TookALevelInBadass: Ariadne. Or Yusuf. Everyone else on the team was badass before the mission.
** Saito gets a bit of this, holding off the incoming mooks with a pistol and grenades while still being injured.
* ToyotaTripwire: Saito appears and knocks out the last mercenary chasing Dom in Mombasa with this.
* TragicVillain: Mal really has no choice about being a psychotic, murderous, obsessed FemmeFatale. She just wants to be with Cobb forever, but the villainous Mal in Cobb's dreams isn't even his real wife, but a shade of the dead woman he can't bear to forget.
* TrappedInASinkingCar: Invoked as part of the kick process in dream level 1. Though the team is equipped with oxygen devices, [[spoiler:Cobb and Saito]] had to be LeftForDead.
* TrashTheSet: Most dreams fall apart at the end, leading to some spectacular special effects.
* TreacherousAdvisor: Fischer's godfather. Or at least the team decides to play up that angle to prevent him from getting control of the company.
* TrueCompanions: The Inception team. Ariadne tells Cobb to get over this guilt not for himself, but so that the others don't stuck in Limbo. [[spoiler:Cobb remains in Limbo to get Saito, who returns the favor by immediately making a call that gets Cobb off the hook.]]
* TwentyMinutesIntoTheFuture: The technology to enter another person's dreamscape is only used by a small number of people. When talking to the professor, Cobb mentions that there are legitimate uses for it, but he hasn't really been able to find honest work after [[spoiler:being accused of killing his wife.]]
* UndisclosedFunds: It isn't out right stated how rich Saito is, but he seems rich enough to buy an entire airline for the operation (in what appears to be seconds), plus have enough connections to [[spoiler:clear Cobb's murder charge.]]
** The speed of the airline purchase is actually the result of how quickly his line goes by. He ''already'' took the precaution of buying the airline, ''before'' telling the group that they would be using it.
* TheUnreveal: [[spoiler:Whether or not Cobb is still dreaming at the end of the movie. Cobb spins the top, but the movie ends before the audience sees whether it falls or not.]]
* UnsettlingGenderReveal: Eames, Forging a woman, does this to Saito. Thankfully, Saito's reaction is mostly "Oh, quit screwing around."
* UpToEleven: It appears that even a two-level dream setup is tricky and reserved for only the most important missions. Cobb wants to go ''three''-levels.
* TheVeryDefinitelyFinalDungeon: Cobb's deepest dream world, which consists of a decaying city full of skyscrapers collapsing into an ocean shoreline. The thunderstorm that happens later on definitely adds into the mood here.
* ViewersAreGeniuses: The first published review by ''Rolling Stone'' suggested that the film is quite ambitious in this regard.
* VisionQuest: The mission becomes this for Cobb when Ariadne tells him he has to [[spoiler:confront Mal, or rather his unresolved subconscious feelings about her]]. Also, [[spoiler:one interpretation of the entire movie is that it's a VisionQuest Cobb is being put through so that he will wake up in reality.]]
* WaistcoatOfStyle: Arthur.
* TheWalrusWasPaul: Creator/ChristopherNolan provides enough conflicting evidence to keep everyone arguing over the ending (or the whole film); anyone looking for a theory that satisfactorily addresses every point is going to have a rough go.
* WasntThatFun: Yusuf after rolling the van and landing it upright.
* TheWatson: Ariadne.
* WellDoneSonGuy: Fischer Jr., [[FlawExploitation which Cobb and the team use to their advantage]].
* AWizardDidIt: As with having all the enemy {{mooks}} [[ImperialStormtrooperMarksmanshipAcademy consistently miss]] when they fire at the heroes, the unique premise of the movie allows Nolan to employ a normally cheesy element of Hollywood blockbusters -- in this case, action sequences that would be [[HollywoodScience physically]] [[ArtisticLicensePhysics impossible]] in real life -- in a way that not only makes sense, but ''enhances the story's believability''.
* WomanInBlack: Mal, being "The Shade."
* WorldOfBadass: In dreams, everyone has ImprobableAimingSkills and mad paramilitary training, even business executives.
* WorldOfCardboardSpeech: Dom gives one in his final confrontation with Mal. [[spoiler: He admits that he wished things didn't happen the way they did and regrets manipulating her with an inception, but explains that trying to keep any "promises" to Mal by growing old together in the dream world is irrelevant. Despite all his imagination the dream Mal is a fragment of the real Mal and he even chastises himself for not being able to do better]].
* WoundedGazelleGambit: Mal [[spoiler:planned to kill herself (though only to "wake up"; she thinks she's dreaming) and convince her husband to go with her, and she used a WoundedGazelleGambit as part of the means of convincing him of that. She told her lawyer that she was fearing for her life, and then trashed the room Cobb was in, just so that if she died and he didn't agree to go with her, everyone would think he killed her. She threatened her own husband with false incrimination on murder, and actually followed through on that threat when he didn't agree to go with her.]] Because of this, she manages to come across as the most [[ManipulativeBastard manipulative]] character in the movie, which says a lot in a movie [[BlackAndGreyMorality where even the good guys are manipulative]].
* WrestlerInAllOfUs: During a zero gravity fight, Arthur grapples a projection mook and chokes him with a cobra clutch with bodyscissors. More than pro wrestling style, however, he performs it in a very MMA/Brazilian jiu-jitsu feeling manner, engaging him frontally and closing guard around him before doing the move.
* WritersCannotDoMath: Dom states that Arthur has "a few minutes" on level two, and that they have "about twenty minutes" on level three. Unless Yusuf suddenly started using a different chemical compound, if Dom and his team have twenty minutes, then Arthur would have one minute. Also, if Arthur had even a couple of minutes, Dom would have at least forty, and the van would have to be in free-fall for six seconds or more, which is a much longer drop than what was shown in the film.
* {{Yandere}}: [[spoiler:Mal. Or at least, the projection of her created by Dom's subconscious. Though real Mal, after her Inception, was a {{Yandere}} as well, seeing as how she pretended to be kind and gentle, but in reality was psychotic beyond words, going so far as to trash her own hotel room as part of an elaborate {{plan}} to make it seem like Cobb killed her.]]
* YearInsideHourOutside: Subjective time stretches in a dream compared to the layer above, with the exact amount of time depending on the sedative used. For the dreams earlier in the movie, time stretches by 12 times per level, for the inception operation, time stretches for 20 times per level.
* YouAllLookFamiliar: If you look closely, you'll notice that Cobb's team [[OnlySixFaces keeps fighting the same projections over and over.]]
* YouCannotKillAnIdea: As seen in the top quote, an idea is the most resilient parasite. Moreover, we're told that subtle as inception must be, it will relentlessly grow into an obsession that can change everything about the target, so it's more like "Don't even [[IncrediblyLamePun dream]] of killing an inception."
* YouCantGoHomeAgain: Cobb cannot return to America or step foot in any country with an extradition treaty with it because [[spoiler:he's accused of killing his wife]]. The main reason he agrees with Saito's request is to have a chance to return home.
* YouHaveFailedMe: Never get hired to do corporate espionage for Cobol Corp.
* YourMindMakesItReal: They manage to avert actually uttering the line, but they come darn close. Totally subverted when it is shown that dying is actually the easiest way to escape from a dream. Unless you're too heavily sedated to wake up, in which case [[AndIMustScream you are doomed to dream for near-eternity]]. Played straight with pain, for it is a function of the mind anyway.
* YourPrincessIsInAnotherCastle: [[spoiler:TheTeam was literally a few steps away from the final vault when Fischer Jr. was shot, and they were forced to travel into another level of subconscious to finish the mission.]]
* ZergRush: Non-militarized projections are limited to this, forming enormous crowds of hostile people who overwhelm intruders through sheer numbers. Militarized projections are more controlled, better-armed, and come in fewer numbers, but no less suicidally relentless.
* ZigZaggingTrope: As noted above, the film initially subverts the typical "[[YourMindMakesItReal if you die in a dream, you die in reality]]" idea, but then plays it straighter later on, as [[spoiler:if you are very deeply sedated, dying in the dream means you lose your mind in real life due to being [[AndIMustScream trapped]] in a LotusEaterMachine for what might seem like eternity, and then subverts it again as it is possible to escape from said LotusEaterMachine very easily if you know how, and if you're willing to, which is, of course, much harder when you don't know that you're in the dream world, or just plain refuse to leave.]]
