->''"I can tell you the license plate numbers of all six cars outside. I can tell you that our waitress is left-handed and the guy sitting up at the counter weighs two hundred and fifteen pounds and knows how to handle himself. I know the best place to look for a gun is the cab of the gray truck outside, and at this altitude, I can run flat out for a half mile before my hands start shaking. Now why would I know that? How can I know that and not know who I am?"''
-->-- '''Jason Bourne''', ''Film/TheBourneIdentity''

A [[TrilogyCreep series]] of action films tenuously ([[InNameOnly pretty tenuously]]) based on the [[Literature/TheBourneSeries Robert Ludlum books of the same name]] and starring Creator/MattDamon.

This series revolutionized the SpyFiction movie genre for its simplicity and glamourless grittiness (as opposed to TuxedoAndMartini), as well as for having a smart protagonist, globetrotting (with virtually zero CaliforniaDoubling), well-crafted suspense and aggressive action sequences.

The main protagonist is Jason Bourne, an amnesiac who finds himself with [[ProfessionalKiller super-assassin]] skills and has to stay on the run from former employers and whoever else wants to manipulate him to evil ends. Each movie follows a slightly different story but retains some basic elements of Bourne eluding government custody, killing a fellow assassin with some household implement and going for an innovative and harrowing car chase.

So far, there are five films in the series:
* ''Film/TheBourneIdentity'' (2002)
* ''Film/TheBourneSupremacy'' (2004)
* ''Film/TheBourneUltimatum'' (2007)
* ''Film/TheBourneLegacy'' (2012)
* ''Film/JasonBourne'' (2016)

A video game adaptation of the first film was released for the Playstation 3 and Xbox 360:
* ''VideoGame/TheBourneConspiracy'' (2008)

The success of the first three films [[FollowTheLeader helped influence the style of many modern action films]], including the gritty direction of the rebooted ''Film/JamesBond'' franchise, especially with ''Film/QuantumOfSolace''.
!!This series as a whole provides examples of:

* ActionFilmQuietDramaScene: Several, including the dialogue with Professor in ''Identity'', Bourne's apology to Irena Neski in ''Supremacy'', and the conversation (rather monologue) with Nicky in ''Ultimatum''.
* AdaptationalVillainy: On multiple levels. In the books, Bourne was [[spoiler: not really an assassin, but a deep-cover CIA operative posing as one to bring down an assassin]]. In the films on the other hand, he actually was an assassin for the CIA. Moreover, Conklin in the books, while playing a similar role as Bourne's Treadstone handler, was a far more sympathetic character who, in the second and third books [[spoiler: becomes a close friend and ally of Bourne's]], whereas in the film he's portrayed as nothing more than another amoral CIA bureaucrat. Most significantly, [[spoiler: Ward Abbott]]'s equivalent in the books was essentially the BigGood of the first book; he's revealed to be a corrupt CIA official in the films.
* AnyoneCanDie: Several important characters are surprisingly dispatched over the course of the series:
** In the first film, [[spoiler:Conklin]] is anti-climactically murdered at the end.
** In ''Supremacy'', [[spoiler: Marie (a character who survived the entire book series]]) is suddenly killed during a chase sequence. Later, [[spoiler: Danny Zorn, Conklin's right-hand man and one of the few surviving Treadstone agents, is murdered by Ward Abbott. Abbott is later exposed as a murderer and traitor and commits suicide.]]
** In ''Ultimatum'', [[spoiler:Simon Ross (played by notable actor Paddy Considine)]] is set up to be a main character, then efficiently dispatched by an assassin. [[spoiler: Neal Daniels is set up to be the man who could answer Bourne's questions, but is blown up.]]
** In ''Jason Bourne'', [[spoiler:Nicky Parsons, after having been in the series since the very first one, ''Identity'', finally bites it.]] In fact the only major characters to survive the series are [[spoiler:Bourne and Pamela Landy]].
* ArcWords: "Look at us. Look at what they make you give."
* ArtifactTitle: ''The Bourne Identity'' makes sense given the context of the movie. ''The Bourne Supremacy'' and ''The Bourne Ultimatum''... less so. And of course, ''The Bourne Legacy'' doesn't even have Bourne in it (though that's the "legacy" part).
* AscendedExtra: Creator/JuliaStiles character Nicky was a very minor character in ''Identity'', and would have been completely overlooked if it wasn't someone with Stiles name recognition playing her. She returned in ''Supremacy'' with an enlarged role based on her involvement with Treadstone in the first film. In ''Ultimatum'' she ends up becoming a co-protagonist with Bourne, using her knowledge of mission protocol to help root out a Blackbriar assassin and hinting that they knew each other before Jason signed up for Treadstone. In ''Jason Bourne'', she discovers more about Bourne's life as David Webb [[spoiler:which gets her killed by the same CIA asset that killed Bourne's father]].
* AssassinOutclassin: The majority of action scenes are either chase scenes, Bourne beating up mooks, or confrontations with government "assets". If Bourne is the target, [[PlotArmor expect the asset to fail]]. If Bourne isn't the target, [[AnyoneCanDie all bets are off]].
* TheAtoner: Bourne.
* AwesomenessByAnalysis: Bourne is a master at this, calmly assessing a situation before acting.
* BeingWatched: Jason can plot the location and arc sweeps of multiple surveillance cameras at a glance and guide others through them as well as himself.
* BlackShirt: Noah Vosen.
* BootstrappedTheme: It was originally just the closing credits music for the first movie, but we've probably reached the point where it's not a Bourne movie without a mix of Moby's "Extreme Ways". The distinctive opening bars in particular have become Bourne's {{Leitmotif}}.
* CarFu: Used by both Bourne and the hitmen sent to eliminate him during the {{car chase}}s in the second and third movie. LARX-3 constantly crashes cars and at one point a bus in an effort to kill Cross in ''Legacy''. Taken to an extreme in ''Jason Bourne'' when [[spoiler: the Asset uses a stolen SWAT vehicle to PLOW through Las Vegas traffic.]]
* CentralTheme: '''Identity'''.
* CharlesAtlasSuperpower: Subverted, ultimately; Jason Bourne manages some exceptional, apparently superhuman feats, but the fourth movie shows that Treadstone's personnel, along with several other project's agents, were actually altered by retroviral engineering to be stronger, smarter, and faster than ordinary humans.
* CombatPragmatist: Bourne gets the job done, whatever it takes. Cross too.
** GroinAttack
** ImprovisedWeapon
* ContractOnTheHitman: The various hitmen hired to kill Bourne. And, indeed, Bourne himself.
* ChronicBackstabbingDisorder: Ward Abbott, who first betrayed his superiors to form a black ops squad with Conklin, then betrayed his black ops squad to use it for personal gain and finally betrayed Conklin as well.
* CursedWithAwesome: Bourne and Cross.
* DeadlyDoctor: Albert Hirsch, the mastermind.
* DeadpanSnarker: A lot of the characters, especially the employees of the CIA.
* {{Determinator}}: Insert whoever belongs to the superhuman projects here.
* DidYouActuallyBelieve: See trope page.
* TheDragon: Conklin to a number of [[BigBad Big Bads]] in ''Identity''; Vosen to Hirsch and Kramer in ''Ultimatum'', Byer to Kramer in ''Legacy''.
* DrivesLikeCrazy: The chases, natch. Mostly justified in ''Legacy'', since drivers on the streets across the UsefulNotes/{{Philippines}} ''actually drive like that''.
* EliteMooks: Treadstone/Blackbriar operatives.
** In ''Legacy'', there is the utterly frightening LARX agent, arguably the most elite of these mooks, almost Franchise/{{Terminator}}-like in ruthless efficiency.
* EasyAmnesia: Averted. Bourne is suffering from dissociative amnesia, caused by the mental trauma of breaking years of training and protocol by refusing to complete his mission, as well as his internal conflict about being an assassin. The physical injuries he sustained, followed by hours of floating unprotected in the ocean, may have contributed as well.
* EscortMission:
** In ''Ultimatum'', Bourne guides reporter Simon Ross (carrying important information about Black Briar) through Waterloo Station evading agents out to get Ross, mostly through instructions via cell phone. A potentially awesome escape [[spoiler: is averted when Ross deviates from Bourne's instructions and in a panic, [[LeeroyJenkins rushes into the open]], prompting [[PrettyLittleHeadshots a headshot from an awaiting sniper.]]]]
** In ''Legacy'', Aaron Cross has to take Marta to UsefulNotes/{{Manila}} to obtain the medication. She was already being tracked by the CIA/Outcome operatives.
** Played with in ''Jason Bourne'' where he is escorting Nicky, but split up midway.
* EvenEvilHasStandards: Treadstone is supposed to have transformed Bourne into the ultimate assassin, [[spoiler:but he can't bring himself to kill a father while his kids are watching.]] His plan necessitated a lack of witnesses, [[spoiler:meaning if he had killed Wombosi, said children would have been next.]]
* EveryCarIsAPinto: Avoided, but played straight once in ''Identity''.
* EvilMentor: Dr. Albert Hirsch
* FilmNoir: Some of the stylistic elements of the series (e. g. Bourne is a loner on the run investigating the convoluted secrets behind his past, most of the action in Europe takes place during the snowy winter months, adding to the gloomy atmosphere, etc.).
* TheFilmOfTheBook
* FlatWhat: Marie evokes this trope in the first movie.
* FollowTheLeader: You can see a lot of influence these films have had on similar genres, both in movies and television, including ''Film/JamesBond'' (post-''Film/CasinoRoyale2006''), ''{{Film/Taken}}'', ''Series/BurnNotice'' and ''Series/{{Leverage}}''.
* GeniusBruiser:
** Bourne is what you get if you combine [[Film/JamesBond Bond]] and Franchise/{{Batman}}.
** Same for Aaron Cross, as the alterations specifically allowed him to have a sharper thinking process and increased strength.
* TheGovernment: The movies take a very unsympathetic view about American government. More specifically, they portray the government as made up by ethically bankrupt officials busy conducting illegal assassination projects, and when those projects are exposed, they choose to kill their fellow countrymen rather than face trial. This is most notable in Legacy, where no one officials question the illegality of murdering fellow Americans. In fact, all of them appear to regard their targets as terrorists.
* HeelFaceTurn:
** Bourne's semi-voluntary defection to the side of niceness.
** Also, in ''Ultimatum'': [[spoiler:Pamela Landy's switch from hunting Bourne to helping him and blowing the whistle on Operation Blackbriar.]]
** Nicky also switches sides for Bourne.
* HeroAntagonist: Pamela Landy in ''Supremacy'' and ''Ultimatum'', until [[spoiler:she blows the whistle on Operation Blackbriar in the latter film.]]
%%* HeroesWantRedHeads
* HiddenSupplies: Bourne's only clue to his identity was a safety deposit box in Switzerland, with cash, fake [=ID=]'s for multiple countries and a gun. Aaron had a car parked in an unknown location with similar items hidden inside one of the doors.
%%* HotPursuit
* HitmanWithAHeart: Bourne, sort of.
** Legacy also showed that the Scientists were beginning to find this a problem in both Treadstone and Outcome agents, thus developed LARX agents to be more efficient.
* HyperAwareness: In the books and movies, but much more noticeable in the books, where Bourne can ''sense'' he's being trailed.
* ICanSeeYou: Bourne likes pulling this trope across the movies.
** When Bourne calls Pamela Landy at her office, he lets her know he's within line of sight.
-->'''Bourne''': Get some rest, Pam. You look tired. *click*
** A similar example: Bourne requests a meeting with Nicky. He is asked what if they can't find her.
-->'''Bourne''': That's easy. She's standing right next to you.
** An inversion happens during Bourne's phone conversation with Vosen later on.
-->'''Bourne''': [[spoiler:If you were in your office, we'd be having this conversation face to face]].
* ImmuneToDrugs: What fact could make ''Supremacy's'' final chase scene [[SerialEscalation even more]] awesome? Both Bourne and Kirill will have been WASTED while it was going on.
%%* ImpossibleMissionCollapse
* ImprobableAge:
** Nicky Parsons (Julia Stiles) is one of Bourne's field handlers on an extremely sensitive mission and apparently has beyond Top Secret clearance given what she is involved in (monitoring ''all'' of the Treadstone field agents). In other words, significantly more dangerous to the Agency than Bourne is if she screws up, or if something was missed in her vetting and she is less than 100% loyal. When the movie was filmed, Julia Stiles was a very young looking ''twenty-one.'' There's an attempted {{lampshade|Hanging}} in ''Supremacy'' when Nicky explains her cover was an exchange student studying in Paris. In the fifth film, she's identified as being in her early-mid 30s, and since the film is set 12 years after ''Ultimatum'' this trope comes up again.
** Bourne himself looks like he could be another offender, but Damon is just very [[OlderThanTheyLook slow aging]]. He is a very boyish looking 31-32 during filming of the first movie, which is actually appropriate for [[spoiler:an experienced soldier who volunteers for a CIA black ops job]], and Jason's file in Ultimatum confirms his birth year is the same as Damon's.
* ImprovisedWeapon: Bourne has used pens, magazines, hand towels, and bathrooms as lethal weapons. Yes, the whole bathroom. And a toaster. In the bonus features, it's revealed that he uses Filipino Kali, a practical martial art that emphasizes quick reflexes and subduing enemies while using improvised weapons.
* IndyPloy: Arguably, since Bourne is constantly forced to improvise some kind of escape.
* InNameOnly:
** The premise is mostly kept intact, but the film and book series diverge wildly in where they go from there. The movies are well-crafted and well-respected, having set a new standard for action flicks. They just, you know, don't follow Ludlum's plot.
** ''The Bourne Legacy'' is the most spectacular example of this. Not only does it not follow the novel, the eponymous Bourne himself does not appear in person.
* ISurrenderSuckers: Used by Bourne in ''Supremacy'', when he intentionally lets himself be caught in USA consulate in Naples, and again in ''Ultimatum'', surrendering to the NY police to hijack their car.
* JitterCam: In the last two films. The second one, especially, gave many theater-goers headaches. Toned down for the third. ''Legacy'' featured a new director and thus was removed almost entirely, in favor of zooming in too close to the action and cutting between shots far too frequently.
* JustAStupidAccent: Largely averted. Foreign characters are usually shown speaking in their native tongue.
* KnightInSourArmor: Pamela Landy.
* LeParkour:
** Frequently used by Bourne to escape his pursuers. Helped popularize the art.
** Also used by Aaron Cross as short cuts to the second floor of Marta's house, and all over the roofs of Manila.
* LongRunnerTechMarchesOn: Very subtly done. In ''Film/TheBourneIdentity'' (2002), all the mobile phones are late-90s basic phones and we see [=PCs=] with massive CRT monitors. By ''Film/TheBourneSupremacy'' (2004), we start seeing early smartphones and [=PDAs=], such as the HP [=iPaq=] used to ID Bourne's (faked) fingerprint, and flatscreen monitors. ''Film/JasonBourne'' (2016) features recent smartphones and mobile apps, with a subplot involving a social media CEO.
* LoveRedeems: Bourne refrains from killing for Marie's sake.
* MacGyvering: Bourne frequently does this.
* MadLibThrillerTitle: ''The Bourne'' [X]. Averted with ''Film/JasonBourne''.
* MakeItLookLikeAnAccident:
** In ''Supremacy'', Jason expected Vladimir Neski to be alone, but realizing his wife was with him, he killed them both, and made it look like a murder-suicide by Neski's wife.
** In ''Legacy'', the Outcome agents are poisoned so their deaths appear from natural causes. The scientists are killed by a colleague going crazy in yet another workplace shooting incident, with the SoleSurvivor meant to have committed suicide. A news report mentions that Hersh died of a 'heart attack' while under protective custody before he had a chance to testify. Only the two Outcome agents miles from civilization are slated to be killed directly.
* TheManBehindTheMan: Layers and layers of it are added in each film, but then again this IS a spy drama.
* MasterOfDisguise: Bourne's character was influenced by 20th-century assassin Carlos "[[Literature/TheDayOfTheJackal The Jackal]]", who was infamous for his ability to blend in and elude the authorities. Carlos himself appears as an antagonist in [[Literature/TheBourneSeries the novels]].
* MrFanservice: Whenever Bourne [[ShirtlessScene takes his shirt off]].
* MythArc: The overarching storyline across all movies is about illegal superhuman assassin projects that are controlled by ethically bankrupt American government officials.
* NeverForgottenSkill: Jason Bourne is introduced with having amnesia. However, his memory loss does not affect his combat skills in the slightest.
* [[NewPowersAsThePlotDemands New Skills as the Plot Demands]]: [[JustifiedTrope Justified]] in the first film; Bourne has a ton of skills that help him disappear, beat people up and kill. He doesn't know about most of them until he has to use them; best demonstrated when a couple cops try to arrest him for sleeping on a park bench. A few seconds later they're both disabled and he is standing over them with one of their service pistols, a look of utter bewilderment on his face.
* {{Omniglot}}: One of the first things Jason Bourne learns about himself after his amnesia is he can speak several different languages including Italian, French and German.
* OmniscientDatabase: The CIA's database. And granted, there's a CD containing various project personnel...
* OnceAnEpisode:
** Bourne outsmarting CIA field agents and cops in a crowd (starting with ''Supremacy'').
** Bourne or Cross battling a rival killer. [[note]]Played with in ''Jason Bourne'' which has only one main physical adversary, who doesn't fight Bourne until the climax, after the OnceAnEpisode car chase.[[/note]]
** Bourne or Cross being chased by cops, on foot or by vehicle.[[note]]''Legacy'' combines the two by having the rival killer attack Cross and Marta while they're being chased by the cops. ''Jason Bourne'' has Bourne chase the Asset this time.[[/note]]
** The ThemeTune "Extreme Ways" by Music/{{Moby}} is played at the end of every movie.
** A CIA official will be directing a large control center full of intelligence agents looking at computers and tracking Bourne or Cross. It's a different CIA official and a different control center every single movie, and the rank of the official and the size of the room seems to get progressively larger.
* OneManArmy: Bourne, and indeed any of the Treadstone/Blackbriar operatives.
* ParanoiaFuel: In-universe. The American government is depicted to be controlled by ethically bankrupt spies who are capable and willing to assassinate anyone (even their fellow Americans) anywhere for self-serving interests. The worst part? Divine intervention aside, they will always get away with it. This is best shown in ''Bourne Legacy'', in the scene where CIA-sent therapists try to kill Marta and make it look like suicide.
* PerpetualFrowner: Most of the cast, including Bourne [[CerebusSyndrome (especially in the second and third movie)]]. Nicky is perhaps the best example, which makes her warm knowing smile seen at the end of ''Ultimatum'' all the more awesome.
* PositiveDiscrimination:
** There are no evil female characters in the first three movies. Either they are sympathetic to begin with, or if antagonistic toward Bourne, are established as being misinformed and at once turn good after learning the truth.
** Does not hold true for ''Legacy'', where the leader of the team sent to kill Marta is a female, as is a prominent member of Byer's team.
* PragmaticAdaptation: The books were written in [[TheEighties the 80's]], with the UsefulNotes/ColdWar going on. This topic just doesn't carry the same impact now. Plus, the real-life terrorist at the center of the book series, Carlos the Jackal, had been in prison years before the movies were ever made.
* ThePrecariousLedge: Jason Bourne escapes the American Embassy by navigating a ledge.
* RealityEnsues:
** At the end of ''Ultimatum'', Landy faxes classified documents about CIA black operations to the public. [[spoiler: This makes her a subject to a criminal investigation in ''Legacy'', because, after all, those documents are ''classified.'']]
** ''Legacy'': Even chemically enhanced, LARX-3 dies when he crashes head-on on a concrete pillar. Similarly, Cross slips out of consciousness after taking a bullet earlier.
*** Cross and Marta bluff their way into a pharmaceutical factory in the Philipines. The bad guys spend a few hours tracking them down, and call the factory management. Turns out said management already figured out something was fishy and were trying to figure out who to call. The manager - who is an average middle aged man - nearly gets both of them caught just by having common sense.
* ReplacementLoveInterest: [[spoiler:Nicky Parsons]], almost.
* RevealingCoverup: The whole point of Treadstone is to avoid this trope, as all of Bourne's kills are supposed to look like internal rivalries or murder/suicides. As Bourne's handler puts it: "I don't send you to kill; I send you because you don't exist!"
* {{Retcon}}: All sequels fill in Bourne's backstory in ways that color the previous film(s) and introduce increasingly higher-ranked government officials who were ''really'' in charge of the Treadstone/Blackbriar program. But the prime example is how ''Ultimatum'' reuses the final scene of Supremacy halfway through its runtime, recontextualizing the dialog and turning the SugarWiki/{{Heartwarming Moment|s}} of ''Supremacy'' into an SugarWiki/{{Awesome Moment|s}} in ''Ultimatum''.
** The plot of ''Legacy'' happens parallel to the closing events of ''Ultimatum'' and twists the outcome of Landy's actions.
* RoofHopping: Happens in ''Ultimatum'' and ''Legacy''.
* RuleOfSymbolism: Water symbolizes death. In ''Identity'', Jason was discovered in the middle of the ocean after having been shot by Wombosi's men. In ''Supremacy'', [[spoiler:Marie gets shot while driving, taking their jeep off the bridge to the water below]], and his first assignment in Treadstone took place on a rainy night. And in ''Ultimatum'', it's shown in flashbacks that, as David Webb, he was waterboarded into becoming Jason Bourne when he first joined Treadstone, and in the end, [[spoiler:he falls into the water after apparently being shot, [[BookEnds mirroring his first appearance]].]]
** Cross' first appearance is him emerging from water, symbolizing his rebirth. It even resembles a baptism.
* SerialEscalation: The first movie concerns about an amnesiac man wanting to quit his job as a black ops killer. Fast forward to the fourth movie, and we have ever-growing superhuman projects engineered by ethically bankrupt officials in charge of American spy agencies.
** The CIA are constantly trying to create the perfect assassin with the following different Operations, in order:
## Treadstone - Agents go through a behaviour-altering programme [[note]]involving waterboarding[[/note]] to make them less empathetic. Agents often suffer from headaches and sensitivity to light. Noted in ''Film/TheBourneLegacy'' to be inconsistent.
## Blackbriar - Successor Operation to Treadstone, no great changes shown.
## Outcome - Agents are physically and mentally improved by taking medication. No apparent behaviour modification.
## LARX - Similar to Outcome, but Agents' medication modifies their behaviour too. They're stronger, smarter, have no empathy, and are essentially brainwashed into becoming TheDeterminator.
* SignificantMonogram: '''J'''ason '''B'''ourne shares more than just his occupation with Film/JamesBond. Also '''J'''ack '''B'''auer. Another badass agent.
* SinisterSurveillance: The CIA, during operations, can hijack cameras nearly everywhere, and still can't catch Bourne. Granted, they ''trained him'' to avoid it, but...
** Not only cameras, but satellites as well, as shown in ''Legacy''.
* SpiritualSuccessor: ''Film/GreenZone'' is from the same director as the second and third films, has the same [[Creator/MattDamon leading man]], is loosely based on a book, involves a possible cover-up, and was even described by Greengrass as "a look inside a privileged world few people see", except it's the military instead of spycraft.
* TheSpook:
** Bourne was trained to become one of these, and it shows what happens when one of these turns back on its creators.
** The Bourne Legacy showed that there was several series of similar programs, which trained at least nine more operatives, including Aaron Cross.
* StairwellChase: [[PlayingWithATrope Played with.]] ''And how !''
* SuspiciouslySimilarSubstitute: The nature of the series and the [[RealLife real-life]] [[TimeSkip time gaps]] in-between releases mean that certain characters have to be written out and replaced by these. Thus, the CIA goes through three different directors over the course of the series (Marshall in ''Supremacy'', Kramer in ''Ultimatum'' and ''Legacy'', Dewey in ''Jason Bourne''), without much in the way of a proper in-universe explanation, and with other characters treating them like they've [[RememberTheNewGuy been there all along.]]
** Noah Vosen is an incorruptible (but no less unethical) Ward Abbott, [[spoiler:though this is due to the latter being killed off as the BigBad in ''Supremacy''.]]
** Nicky becomes one for Marie in ''Ultimatum'' and ''Jason Bourne'', [[spoiler:down to being sniped and killed by TheDragon in the firt act of the latter]], though this is intended more as CharacterDevelopment and CallBack.
** Heather Lee is effectively a younger Pamela Landy, [[spoiler:though significantly less heroic.]]
** Jarda in ''Supremacy'' is an odd example, because it's unclear whether he's intended to be the same character as his counterpart Manheim in ''Identity'', or an InUniverse example of this trope. Both are Treadstone operatives based in Munich, the actors in question look fairly similar, [[spoiler:and Jarda is the only other surviving Treadstone operative at the beginning of ''Supremacy'', with no word given to Manheim's fate. Jarda mentions Conklin's death at the end of the first film (an assassination carried out by Manheim), but his wording remains ambiguous as to if he committed the act personally or is simply recalling it occurring.]] Both possibilities have equal validity, since the films show that [[spoiler:the CIA is not opposed to quietly "retiring" assets.]]
* ThemeTune: "Extreme Ways" by Moby is played at the end of every movie (spinoff included).
* TryingToCatchMeFightingDirty: Bourne. ''A lot.''
* TrilogyCreep: The third film tied things up nicely, though leaving them open ended in case Matt Damon wanted to return as Bourne. When he passed on ''Legacy'' due to Greengrass' lack of involvement, a new character played by Jeremy Renner was written-in. A fifth film starring Damon and directed by Greengrass was released in 2016.
* WalkingTheEarth: [[JustifiedTrope Justified]] by Bourne being on the run. The first half of ''Identity'' even has a certain RoadTripPlot charm to it.
* WeAllLiveInAmerica: It appears the CIA can do almost anything they want in any European country while the local authorities dutifully assist them, or at least don't do anything to hinder them. That the local authorities might refuse to help the CIA based of the fact that an American organization has no jurisdiction in their countries never seems to have crossed the writers' minds.
* WeaponOfChoice: Many of the assassins use weapons manufactured by Sig-Sauer, Glock and Beretta
* WhatHappenedToTheMouse: Due to the long-running, serialized nature of the series, characters and plot points have a tendency to appear and promptly disappear after having fulfilled their purpose in the plot. These include Pamela Landy, Noah Vosen, Martin Marshall, Manheim, Ezra Kramer, and Dr. Albert Hirsch, and almost the entire supporting cast of ''{{The Bourne Legacy}}''.
* XanatosSpeedChess: Bourne is the master of this trope. The CIA operatives try hard to OutGambit him in every movie. They always fail miserably...
