->'''Harmonica:''' The reward for this man is 5,000 dollars, is that right?\\
'''Cheyenne:''' Judas was content for 4,970 dollars less.\\
'''Harmonica:''' There were no dollars in them days.\\
'''Cheyenne:''' But sons of bitches? Yeah.

''Once Upon a Time in the West'' (in Italian: ''C'era una volta il West'') (1968) is considered Creator/SergioLeone's masterpiece; according to Wiki/ThatOtherWiki, it's a prime example of an Epic Western.

It is remembered for its beautiful cinematography, extremely quotable dialogue, and fascinatingly enigmatic characters, as well for its brilliant casting: Creator/CharlesBronson as another [[NoNameGiven "man with no name"]] seeking revenge, Claudia Cardinale as Jill, the young, pretty widow with a past, Jason Robards as the bandit Cheyenne, and Creator/HenryFonda as the [[PlayingAgainstType villainous]] Frank, who works for the [[RailroadBaron railroad tycoon]] Mr. Morton (Gabriele Ferzetti).

CitySlicker Jill arrives at the town of Flagstone by train just as Bronson's [[TheDrifter nameless character drifts]] into town. By chance their paths cross at a roadside establishment. Cheyenne, who has just escaped from his prison escort, dubs Bronson's character "Harmonica." Jill then discovers that her husband and his children have been murdered at their homestead. Frank, the real killer, frames Cheyenne.

Harmonica has a personal vendetta against Frank, so he and Cheyenne fight against Frank and his boss, Mr. Morton. They defend Jill's homestead and discover her late husband's plan to make a fortune.

Based on a story created by Leone, Creator/BernardoBertolucci and Creator/DarioArgento. Under Leone's direction, Music/EnnioMorricone composed the soundtrack before the actual filming started, and most of the narrative is built around the music, instead of the traditional way of fitting the soundtrack to the film.

!!''Once Upon a Time in the West'' provides examples of the following tropes:
* AbsoluteCleavage: Jill, towards the end of the movie.
* AccidentalPublicConfession: A chilling version occurs at the beginning of the movie. Frank and his men have just finished massacring a family, only to exit the house and find a small boy staring at them.
-->'''Mook:''' [[WouldntHurtAChild What're we gonna do with this one]], Frank?\\
'''Frank:''' [[PreMortemOneLiner Well, now that you've called me by name...]]
* AffablyEvil: Cheyenne is a cheerful, friendly fellow who seems perpetually amused by the events in which he is caught up. He's also a confessed murderer and bandit leader. It helps that A) he's not the villain of the film, just the local badman whose territory the villain trespasses on, and B) all of his crimes take place off-screen (just outside the door in the case of his slaughter of his prison escort).
* AlasPoorVillain: [[spoiler:Morton had the desperate goal of seeing the blue ocean of the Pacific before he succumbed to his fatal disease. He instead dies slowly face down in a mud puddle while he imagines to hear the ocean.]]
* AntiHero:
** Harmonica is completely remorseless and nearly machine-like in his pursuit of Frank, using Jill as bait, and brutalizing those who get in his way.
** Cheyenne.
* AntiVillain:
** Cheyenne, who also gains AntiHero traits as the film goes along. It helps that he never kills anybody likable onscreen.
** Mr. Morton, whose primary goal is to see the Pacific Ocean again one last time before succumbing to his disease.
* ArchEnemy: Frank and Harmonica.
* ArtisticLicenseGunSafety: In the opening scene, one of the gunmen catches an annoying fly in the barrel of his gun, then keeps it in by putting his finger on the end, keeping his index finger on the trigger the entire time.
* {{Auction}}: Frank holds a rigged one to sell Jill's land, sending his goons to intimidate people from bidding. Harmonica bids $5, 000 with the bounty on Cheyenne's head.
* BadassBeard:
** Cheyenne's.
** Frank sports one as well. [[spoiler: But only in the flashback at the end of the film.]]
* BadassBoast: Harmonica's first scene, [[ShowdownAtHighNoon when three of Frank's men are waiting for him]]:
---> '''Harmonica:''' Did you bring a horse for me?\\
'''Frank's Man:''' Looks like we're shy one horse.\\
'''Harmonica:''' (shakes head) You brought two too many.
** Cheyenne's reaction upon hearing Harmonica's account of the shooting: "One, nobody around these parts got the guts to wear those dusters except Cheyenne's men. Two, Cheyenne's men don't get killed." He then spins his revolver and states that he can count "All the way up to six if I have to, and maybe even faster than you."
* BadassGrandpa: Frank. His hair is turning gray, but his deadliness and resolve seem as firm as ever.
* BadassLongcoat: Cheyenne's gang. Frank sports a similar outfit when framing Cheyenne for the murder of the [=McBain=] family.
-->'''Cheyenne:''' That's a crazy story, Harmonica, for two reasons. One, nobody around these parts got the guts to wear those dusters except Cheyenne's men. Two, Cheyenne's men don't get killed.
* {{Bandito}}: Frank, in the flashback.
** Cheyenne is a sympathetic example.
%%* BatmanGambit
* BeardOfEvil: Averted. Henry Fonda planned to grow a beard as well as wear brown contact lenses to play Frank, but Sergio Leone talked him out of it, since Fonda having his usual appearance in a role so different from his usual humble and noble characters would make it all the more shocking.
* BestServedCold: [[spoiler:Harmonica's revenge is obtained decades after.]]
* BigBad: Frank. Although he takes his orders from [[BigBadWannabe Morton]], Frank manipulates everyone to function as he wants them to. Furthermore, [[spoiler:he is wanted by Harmonica throughout the film. Its because he wants revenge on him for killing his brother.]]
* BigBadWannabe: Morton. Sure, it was him who hired Frank and set the plan in motion, but compared to him, Morton is much more sympathetic and lacks of ruthlessness. Furthermore, Morton is constantly bullied by Frank.
* BittersweetEnding: [[spoiler: The bad guys die and the train finally gets to Sweetwater, which will grow into a beautiful town where Jill is going to be a very successful woman. On the other hand, Cheyenne, perhaps the most likable character in the film, dies, and Harmonica leaves to (presumably) never be seen again.]] It's also true on a metaphorical level, as it's shown that the advent of the new industrial era (a major theme of the film) wipes the old-fashioned individualist characters - noble warriors and crude villains alike.
* BlackAndGrayMorality: Frank is a sociopath, Cheyenne a bandit, and Harmonica a ruthless gunslinger.
* BreakTheCutie: [[spoiler:Played with. It's straight for four minutes with Jill, in the second last scene, once she realizes that Harmonica will not stay with her, and that she will most likely live as a widow until her death... then inverted, after Cheyenne gives her some advice that takes a few minutes for her to fully comprehend, and then adhere.]]
* ButForMeItWasTuesday: Frank doesn't remember who Harmonica is, although Harmonica isn't keen on reminding him until the end. On the other hand, when Frank demands Harmonica's name, Harmonica responds with a couple pseudonyms -- which Frank ''does'' recognize as the names of other men he's killed. FacialDialogue shows him finally recognizing Harmonica; Frank asks the man for his name and gets a harmonica stuffed into his mouth for an answer.
* ButNowIMustGo: [[spoiler:Harmonica and Cheyenne are drifters with no place in a settled town. Cheyenne is also about to bleed to death, unknown to any of the other characters.]]
* ButtMonkey: Wobbles.
* CaptivityHarmonica: Guess who?
* CharacterTics: Frank is constantly spitting out in a less than pleasant manner, another sign that he'll never make a proper businessman.
* TheChessmaster: Frank--for a time, anyway. Harmonica is revealed to be one, over the course of the film.
* CitySlicker: Jill at first. She can't even start a fire. JustifiedTrope since she's alone with the man who she thinks killed her new family -- it's not at all surprising that her hands are shaking. She gradually evolves via CharacterDevelopment.
* ClickHello: Frank does this to Harmonica when he catches him climbing down the train.
* CloseOnTitle: The film has a very long, drawn-out opening scene in which essentially every possible credit is shown except for the title, which shows up when the end credits begin. Hailing from 1968, this is one of the oldest examples of this trope.
* CombatPragmatist: Harmonica uses HiddenWeapons to get the drop on others. Cheyenne and Frank also show few compunctions, striking from hiding, and distracting opponents in order to win.
* CoolTrain: Morton's special train.
* CreepyBlueEyes: Frank's eyes. [[spoiler:Henry Fonda originally wanted to wear brown contacts, [[GoodEyesEvilEyes as he was playing a villain]]. Leone told him to take them off.]]
* CuffsOffRubWrists: After Cheyenne cuts him loose aboard Morton's train, Harmonica's seen rubbing his wrists in the background.
* DarkIsEvil: Frank goes all black in the second half of the movie.
* DeadpanSnarker: Frank and Harmonica are both exceptionally sarcastic.
* {{Deconstruction}}: Of the Western in general. A widow gains the support of a gunslinger and a local outlaw with a good heart in order to fend off the corrupt railroad tycoon? Sounds like the plot to half the Westerns of the 1950s. [[spoiler:But in this case, the gunslinger isn't doing it for the widow and has his own agenda, the widow in question is a former prostitute who isn't above sleeping with the villain to save her own life, and the bandit chief is protecting her largely because she reminds him of his mother. In the end, the gunslinger moves off for his next showdown, there's no romantic conclusion, and the railroad moves on, pushing the West of the film further and further away.]]
* DeterminedWidow: Jill, although she's somewhat of a deconstruction since she was a HookerWithAHeartOfGold looking for a new life and arrives on the scene after her new family is massacred.
* DidNotGetTheGirl: [[spoiler:Jill has lots of sexual tension with Cheyenne, Frank and Harmonica, but no one gets her. Cheyenne dies, Frank never stood a chance considering who he was and what he did to her, and Harmonica couldn't return her feelings. And since this aspect of the resolution is played largely from Jill's point of view, it's also a case of Did Not Get The Guy]].
* DissonantSerenity: Cheyenne goes about his business and doesn't care one iota about the climatic duel, and is just annoyed when the shooting makes him cut himself while shaving. On top of that, [[spoiler:he's secretly dying]].
* DoesntTrustThoseGuys: "How can you trust a man who wears both a belt and suspenders? The man can't even trust his own pants."
* TheDogBitesBack: Unfortunately for Frank, the young Harmonica eventually grows up to become [[spoiler:Creator/CharlesBronson.]]
* DragonInChief: Frank is the focus of the plot, and has his own agenda, which involves getting Jill to sell the land to him so that he can then sell it to his nominal boss, Mister Morton at a higher price. Toyed with during the later parts of the film, as Morton proves that in his own way, he can be just as dangerous.
* DramaticNecklaceRemoval: Done by Harmonica after the climatic final duel.
* TheDreaded: Frank.
* TheDrifter: Harmonica hits the archetype. Unlike most examples of this trope, he's in town for a specific reason, and not by accident.
* DuelToTheDeath: Harmonica and Frank's showdown.
* DyingAlone: [[spoiler:Cheyenne asks Harmonica to look away.]]
* TheDyingWalk: Before the climax, Frank escapes a shootout with Morton's hired goons and returns to Morton's train to confront him, only to find Morton dying of wounds he sustained during a run-in with the outlaw Cheyenne. Morton, lying pitifully in the dirt, ignores Frank's arrival and instead desperately crawls over to a nearby mud puddle ''representing a stand-in for the Pacific Ocean that he will never be able to reach''.
* EarnYourHappyEnding: [[spoiler:Cheyenne dies, but Frank and his employer are both dead, and Harmonica has avenged his brother. Jill will go on to become a wealthy widow, and a respected and well-loved member of the Sweetwater railroad town.]]
* EndOfAnAge: The railroads herald the end of the Wild West. In RomanticismVersusEnlightenment, the film is firmly on the side of romanticism.
-->'''Harmonica:''' So you found out you're not a businessman after all?\\
'''Frank''': Just a man.\\
'''Harmonica''': An ancient race. [looks to the approaching railroad] Other Mortons will be along and they'll kill it off.
* EstablishingCharacterMoment:
** A man of few words appears in a train station, blows his harmonica and takes care of the three gunmen who were sent to greet him. He outdraws them while his gun was still in his baggage. A classic, mysterious gunslinger and drifter.
** Frank shows up as the leader of a gang that has massacred a family, and ends the deed by killing a little boy.
* EvenEvilHasStandards:
** Cheyenne draws the line at killing children and Catholic priests.
** Mister Morton loathes senseless slaughter, and comes to see Frank as little more than an animal.
* EvilCripple: Morton is a crippled (and dying) and walking only by crutches RailroadBaron. However, he's pretty much a villainous Woobie.
* EvilVersusEvil: Frank and Morton spend the second half of the movie trying to checkmate each other, with increasingly violent results.
* FaceFramedInShadow: Almost every introduction of Harmonica into a scene is like this, especially the scene where he's revealed by a lantern being thrown into the corner of the bar where he's sitting.
* FalseFlagOperation: The massacre of the McBains is carried out by Frank's henchmen (really working for Morton's railroad company) while dressed in dusters like Cheyenne's outlaw gang. A posse spends the first part of the film unsuccessfully tracking Cheyenne.
* FalseReassurance[=/=]MetaphoricallyTrue:
-->'''Morton:''' Tell me, was it necessary that you kill all of them? I only told you to scare them.\\
'''Frank:''' People scare better when they're dying.
* FastestGunInTheWest: Slightly subverted in the first scene: Harmonica manages to draw his gun and to shoot three men who had already their guns in their hands in a row... and then one of them manages to shoot him back before collapsing.
* FauxAffablyEvil: Frank can maintain a layer of civility and behave in a likable, reasonable way when it suits him, but he's eager to murder more and talk less.
* FlashBack: Used to reveal why Harmonica pursues Frank.
* ForDoomTheBellTolls: [[spoiler: Harmonica's brother is hanged from a bell.]]
* GallowsHumor: A dying [[spoiler:Cheyenne]] takes a moment of levity to trifle about his circumstances.
-->'''[[spoiler:Cheyenne]]:''' Hey, Harmonica - when they do you in, pray it's somebody who knows ''where'' to shoot.
* GoodColorsEvilColors: Frank always wears dark brown or black. Harmonica always wears light yellow, almost white.
* GrandFinale: This film is generally seen as the grand finale to Creator/SergioLeone's SpaghettiWestern films. Or as the prelude to the [[Film/AFistfulOfDynamite grand finale]].
* TheGunslinger: Harmonica, Frank, and Cheyenne.
* HandicappedBadass: Morton. Not only does he have the balls to play mind games with Frank, [[spoiler: he would have succeeded in having him killed as well, if [[TheOnlyOneAllowedToDefeatYou Harmonica hadn't intervened.]] He also killed Cheyenne.]] Frank even [[LampshadeHanging lampshades]] it:
-->'''Frank:''' Who knows how far you'd have gone with two good legs.
* HairTriggerTemper: Frank is this when he's angered.
-->'''Frank:''' How can you trust a man who wears both a belt and suspenders? The man can't even trust his own pants!
* HeroicBSOD: [[spoiler: Jill during her final meeting with both Cheyenne and Harmonica]].
* HonorBeforeReason: Frank has a chance to ride away safely after killing his boss, Morton. Instead he comes back to face his nemesis, the man with the harmonica.
-->'''Frank:''' "Morton once told me I could never be like him. Now I understand why. Wouldn't have bothered him, knowing you were around somewhere alive."\\
'''Harmonica:''' "So, you found out you're not a businessman after all."\\
'''Frank:''' "Just a man."
* HookerWithAHeartOfGold: Jill is the most morally sound character in the film.
-->'''Cheyenne:''' You know, Jill, you remind me of my mother. She was the biggest whore in Alameda and the finest woman that ever lived. Whoever my father was, for an hour or for a month, he must have been a happy man.
* IHaveYouNowMyPretty:
** Played straight by Frank. [[spoiler:Jill submits however in order to save her life, even pretending to like it.]]
** There's a subversion in a bizarre scene near the beginning where Harmonica ambushes Jill in a barn, roughs her up a little and rips her dress... but it turns out he's [[InvokedTrope deliberately invoking]] MaleGaze by [[AbsoluteCleavage tearing her dress]] and [[UnkemptBeauty having her hair whipped around a little]]. There may be assassins just outside, but [[AllMenArePerverts not even they can avert their eyes from the eye-candy]]... except for maybe Harmonica. Look at him closely. He's doing this almost surgically and with extreme care.
* IneffectualSympatheticVillain: Mr. Morton doesn't do much killing, being a [[EvilCripple crippled]], dying old man. His last dream is to see the Pacific Ocean before he dies. [[spoiler:He spends his dying moments desperately crawling towards a small, muddy puddle as a substitute for the Pacific.]]
* InstantDeathBullet: The slaughter of the [=McBain=] family plays out as this, as does the shootout at the railroad in the opening scene.
* InvincibleHero: {{Averted|Trope}} right from the start, as Harmonica, badass though he unquestionably is, is wounded in the very first fight. From then on, it's not inconceivable that he might lose to Frank.
* IronicEcho: [[spoiler: Harmonica places his harmonica between the lips of a moribund Frank]], a CallBack to the death of [[spoiler: Harmonica's brother, which Frank caused by hanging him from a bell.]]
* ItsPersonalWithTheDragon: Harmonica interferes with railroad baron Mr. Morton's efforts to take Jill McBain's land, but his primary goal is to kill Morton's henchman Frank, who killed Harmonica's brother decades earlier.
* JackBauerInterrogationTechnique: Harmonica tortures a man to get information of Frank.
* JerkWithAHeartOfGold: Mr. [=McBain=] abuses one of his sons when the lad talks back, and seems to be a domineering man in general, but it's also evident that the man deeply cares for his family, specially for his daughter.
* JerkWithAHeartOfJerk: Frank. He shows no remorse for his actions whatsoever, and his less indecent actions are motivated by the wrong reasons, be it sadism or greed.
* JustifiedCriminal: Cheyenne, who actually helps the protagonists after being framed for a series of murders he didn't commit, even going as far as to allow himself to be turned in so that the reward money can be used to keep Jill's farm.
* KickTheDog:
** Frank and his gang kill a family of four, including a young child.
** Frank gets another one near the end of the film in the [[spoiler: "keep your lovin' brother happy" flashback. While Frank does spare the life of young Harmonica, he does it only [[TheSociopath to experience sadistic glee]] at seeing the guy witness the murder of his brother.]]
** Frank kicking Morton's crutches out from under him.
* KilledOffscreen:
** [[spoiler:Cheyenne]] provides a playful double example. First, he's mortally wounded in an off-screen skirmish, and then during his actual death, he asks his companion to look away, which the camera also respects with a brief discretion shot.
** When Frank shoots the younger [=McBain=] boy, the camera cuts away to the train with Jill arriving at the station, [[MatchCut merging the sound of the bullet with the train's whistle.]]
** [[spoiler: All of Cheyenne's men and the last five of Morton's men, killed in the train battle.]]
* LeaveNoWitnesses: One of the earliest evil deeds Frank does is kill a child after this sinister excerpt of dialogue:
-->'''Goon:''' ''[about the boy]'' What are we gonna do with him, Frank?\\
'''Frank:''' ''[beat]'' Well, now that you've called me by name -- ''[shoots the child]''
* {{Leitmotif}}: Most of the main characters have their own - Jill a romantic harmony, Cheyenne a comical banjo, Frank a sinister electric guitar and Harmonica is self-explanatory. During Frank and Harmonica's duel, their themes overlap.
* LeaveTheCameraRunning: Creator/SergioLeone's signature style, the first scene has the characters waiting for a train and runs for almost 15 minutes before the first words are spoken.
* LeftTheBackgroundMusicOn: Just before Harmonica's entrance, the music changes subtly. Everybody starts looking around, then it is revealed the new tune is being played by a man with a harmonica.
* LightIsGood: Harmonica. Basically Sergio Leone [[PlayingWithATrope playing with]] the Western tradition of the "good guys" wearing white hats.
* LoveableRogue: Cheyenne
* LoveTriangle: Very subtle. Over the course of the film, Cheyenne gets a bit of a soft spot for Jill. Who in turn develops one for Harmonica. [[spoiler:Harmonica's feelings are unsaid and he moves on at the end of the film.]]
* MailOrderBride: Jill [=McBain=]
* ManInWhite: It's easy to miss, but Harmonica dresses almost completely in white. Or in his case, a worn and patched outfit in a range of light beige and sand colors. Which in this world is as white as it gets.
* MsFanservice: Jill has a lot of moments of this, [[ReluctantFanserviceGirl often against her wishes.]]
* MissKitty: Jill is a former prostitute.
* MortalWoundReveal: [[spoiler:Happens with Cheyenne, after his ambush of the the rail baron's private train.]]
* MotivatedByFear: Frank quipping to Mr. Morton, that people are more likely sell the land to them if they're properly scared and that 'people scare better when they're dying.'
* MurderIsTheBestSolution: Morton just wants his opposition bought out or intimidated, but Frank prefers to massacre first and ask questions later.
-->'''Morton:''' Tell me, was it necessary that you kill all of them? I only told you to scare them.\\
'''Frank:''' People scare better when they're dying.
* MusicalisInterruptus: Cheyenne's theme pauses several times so he can say a line, and starts up again. It even stops to allow [[spoiler:his dead body to drop to the ground.]]
* MutualKill: A delayed one. [[spoiler:During a shootout Mister Morton and Cheyenne mortally wound one another. Morton dies a few minutes later, Cheyenne a few hours later.]]
* MyNameIsInigoMontoya: Beautifully subverted. Harmonica never tells Frank his name. When Frank demands to know, he gives him plenty of names, but none of them his.
-->'''Frank:''' Who are you?\\
'''Harmonica:''' Jim Cooper, Chuck Youngblood.\\
'''Frank:''' More dead men.\\
'''Harmonica:''' They were all alive until they met you, Frank.
* NeverTrustATrailer: [[http://youtu.be/_T41xBHV01c The trailer]] makes it look like Harmonica is the villain of the film, and a ruthless killing machine. Frank, meanwhile, almost looks like he's the hero.
* NiceGuy:
** Cheyenne has his moments in the film.
** Jill is a NiceGal.
* NoNameGiven: The man out for revenge is [[OnlyKnownByTheirNickname only ever called]] Harmonica, as he plays a harmonica everywhere he goes. Cheyenne is probably an alias too and Frank an example of NoLastNameGiven. All this adds a lot of mystique to the story.
* NoPlaceForMeThere: Once his business is completed, Harmonica leaves Sweetwater, as the new society has no use for him.
* NonActionBigBad: Mr. Morton. A theme of the movie is how new money will displace old weapons in the villainy business.
-->'''Morton:''' How does it feel sitting behind that desk, Frank?\\
'''Frank:''' Almost like holding a gun... only much more powerful.
* NotMeThisTime: Frank frames Cheyenne for the massacre of the [=McBain=] family, knowing that it's plausible since Cheyenne's no saint himself.
* NotSoHarmlessVillain: [[spoiler:Mr. Morton, who refuses to be intimidated, convinces Frank's men to betray him, and kills Cheyenne.]]
* NotSoStoic: Harmonica remains calm for the most part, and even when he is annoyed it comes off as mild. [[spoiler:But he's crying in the flashback of his brother's death.]]
* NumberTwo:
** Cheyenne has an unnamed lieutenant, who among other things, is responsible for carrying his coat and smuggles him off the train to Yuma "Two tickets, amigo, to the next station. One way only." He gets killed in the shootout with Morton's men.
** Frank has two: One participates in the massacre of the [=McBain=] family (he's the one who asks "What are we going to do with this one, Frank?" and the other found Jim and Logan dead, killed by Harmonica and reports that to Frank. Both are killed by Cheyenne's men.
* OceanAwe: Mr. Morton is motivated by a desire to see the Pacific Ocean before he dies from his illness.
* OffscreenMomentOfAwesome: Cheyenne gets two: his escape from a prison escort and his shootout with Morton and his henchmen.
* OnceUponATime
* OneWomanWail: "Jill's America"
* OnlyICanKillHim: Averted. There's a good reason to suspect that [[spoiler: Frank]] would have been killed by [[spoiler: his own henchmen, bribed by Morton]] if it were not for [[spoiler: Harmonica's TheOnlyOneAllowedToDefeatYou]]; and [[spoiler: Cheyenne]] was killed by [[spoiler: crippled Mr. Morton]]. That both cases are attributable to Mr. Morton is no coincidence, as it shows that in this new world the power of money is going to eventually prevail.
* TheOnlyOneAllowedToDefeatYou: Why Harmonica helps Frank against Morton's minions.
-->'''Jill:''' You saved his life!\\
'''Harmonica:''' I didn't let them ''kill'' him and that's not the same thing.
* OverlyLongGag: Frank's henchman Snaky getting increasingly annoyed by a fly landing on his face. There's also the joke of a residue or water dripping from the ceiling onto Stony's head, and then onto his hat.
* PetTheDog: Jill serves as a big MoralityPet for Cheyenne.
* PoliceAreUseless: The Sheriff of Flagstone's only role in the movie is to oversee Jill's auction of Sweetwater. In a deleted scene his deputies rough up Harmonica, and he's revealed to be a DirtyCop on Morton's payroll.
* PostModernism: See {{Deconstruction}} or [[http://en.wikipedia.org/wiki/Once_Upon_a_Time_in_the_West#Film_references Wikipedia]]. French theorist [[http://en.wikipedia.org/wiki/Jean_Baudrillard Jean Baudrillard]] once deemed ''Once Upon a Time in the West'' the first postmodern film.
* PreAsskickingOneLiner: "When you hear a strange sound, drop to the ground..." It's [[CallBack referenced in a later shootout]]:
-->'''Jill:''' I swear we're gonna hear that strange sound again.\\
'''Harmonica:''' Right about... ''now.''
* PriceOnTheirHead: Cheyenne has a $5,000 bounty on his head, which Harmonica uses to bid for Sweetwater and save it from Frank and his goons during the auction.
* PsychoForHire: Frank, who enjoys killing every bit as much as he enjoys the money he makes from it.
* PunchSpinGape: A gunshot instead of a punch, but this happens to [spoiler:Frank]].
* QuickDraw: Harmonica has a very fast one. So does Frank. And Cheyenne.
* TheQuietOne: Harmonica is the strong, silent type. He prefers to let his instrument, revolver and [[DeathGlare body language]] do the talk.
* RaceLift: Cheyenne was originally Mexican, his real name being Manuel Gutierrez, according to the script. Creator/SergioLeone didn't feel that Jason Robards made a convincing Mexican, so he dropped this.
* RailroadBaron: Mr. Morton.
* RailroadPlot: [[spoiler:McBain knew that any train line through the region could only refuel water for the steam engine in a single place and build his farm on the site, expecting to make a small fortune by selling water to the train company. So Morton had the family killed by Frank so that he could buy the land himself.]]
* RedemptionEqualsDeath: [[spoiler: Cheyenne doesn't get to enjoy his newly heroic life very long.]]
* RedOniBlueOni: Cheyenne and Harmonica respectively.
* ReluctantFanserviceGirl: Jill gets her dress ripped by Harmonica, and is seen wearing nothing but a towel.
* RetiredOutlaw: Frank is a former bandit, who now works for the railroad company. This has not made him a more sympathetic individual.
* TheReveal: [[spoiler: Harmonica's motivation for wanting to kill Frank. Frank hanged Harmonica's brother with sadism; a young Harmonica, on his knees, was made to support his older brother above his shoulders, until the inevitable happened when he either collapsed from exhaustion or his brother kicked him away on purpose.]]
* {{Revenge}}: Harmonica is driven entirely by desire for revenge on Frank.
* RewatchBonus: On the second viewing, [[spoiler: Cheyenne's grave condition]] is painfully obvious. He even [[spoiler: holds his hand over the bullet wound]] while approaching Harmonica.
* RoaringRampageOfRevenge: Harmonica obviously has a serious beef against Frank, going as far as to protect him from his other enemies just so he can have the privilege of killing Frank himself. [[spoiler:In the end, we find out that he's avenging his brother, who Frank killed in one of the most unforgivable fashions possible when Harmonica was just a little kid.]]
* {{Sadist}}: Take a wild guess.
* SameContentDifferentRating: The film features about the same amount of violence and mature themes as Sergio Leone's previous westerns, but it got an M (a precursor to PG) whereas the others all got Rs. In 2003 it was updated to a PG-13.
* SaveTheVillain: Harmonica kills one member of Frank's gang when they betray him for Morton and try to kill him. But unlike other examples of this trope, he's not doing this to save his life, as Jill accuses him of doing, but because Harmonica hates Frank enough to consider himself the only one allowed to kill him.
* SayMyName: "MAUREEN!" It's quite heartbreaking.
* SceneryPorn: Emphasis on Monument Valley, Utah.
* ScrewTheRulesIHaveMoney:
-->'''Mr. Morton''': There are many things you'll never understand. This is one of them. *holds a stack of dollars while looking at Frank's drawn gun* You see, Frank, there are many kinds of weapons. And the only one that can stop that is this. Now, shall we get back to our little problem?
* SecretStabWound: Gunshot wound, actually.
* SecretlyDying: Due to the above gunshot wound. Throughout the whole of the last scene with Jill, you can tell that there's something wrong [[spoiler:with Cheyenne, but he's doing his best to hide it from her. It's only once he leaves that we find out what happened.]]
* SettlingTheFrontier: [[spoiler:Jill becomes the matriarch of the small community literally being built up around her as the railroad approaches.]]
* ShipTease and ShipSinking: Jill seems to be showing interest in Harmonica and Cheyenne as the film progresses. However, [[spoiler: when Jill expresses her interest in Cheyenne, he replies that he's not the right man...and neither is Harmonica.]]
* ShoutOut:
** Bursting with references both obvious and subtle to classic American Westerns, from ''Film/HighNoon'' and ''Film/{{Shane}}'' to ''Johnny Guitar'' and ''Run of the Arrow''.
* ShowdownAtHighNoon: Harmonica and Frank finally settle their conflict this way.
* SignatureStyle: This film signals a shift to the second phase of Creator/SergioLeone's style, being slower and more serious than the ''Film/DollarsTrilogy''.
* SilenceIsGolden: The opening has no dialogue as a trio of gunman wait for their target to arrive on a train. The final showdown is over nine minutes long, in which a total of 8 words are spoken.
* SlasherSmile: Frank and some of his men [[spoiler:in Harmonica's flashback.]]
* TheSmurfettePrinciple: Jill is the only female member of the principal cast.
* TheSociopath: Frank is possibly one of the most perfect examples in a Creator/SergioLeone film..
* SonOfAWhore: Cheyenne. [[EvenBadMenLoveTheirMamas He still calls her "the finest woman who ever lived".]]
* SoundtrackDissonance: [[spoiler:Cheyenne's upbeat little motif plays as he dies.]]
* SpaghettiWestern
* SpecialGuest:
** Woody Strode and Jack Elam as two of the hitmen waiting for the train at the beginning.
** Keenan Wynn as the Sheriff at the auction, Frank Wolff as Jill's ill-fated husband, and Lionel Stander as the barman at the saloon where we first encounter Cheyenne.
* TheStarscream: Frank becomes this to Morton. Flawed as he finds Morton, Franks holds some respect for the man's tenacity in the process.
* SugarAndIcePersonality: Jill. She's icey towards Cheyenne and Harmonica in their first interactions, but eventually warms up to them.
* TeamDad: Cheyenne to a degree. He goes out of his way to protect Jill and Harmonica. And while he speaks rough of his men, he trusts them.
* ThemeMusicPowerUp: The spooky sound of the hamonica accompanies his raging revenge through the movie, and every time you hear it you know that he'll do something awesome.
* TookALevelInBadass:
** Jill rides into town a somewhat aloof city girl and ends up the head of a soon-to-be-functioning, prosperous railroad company.
** Harmonica from his childhood incarnate, where [[spoiler:Frank had him tied down to a post with a harmonica in his mouth, hence the reason Harmonica wants to kill Frank.]]
* TrailersAlwaysSpoil: The synopsis on the back of the DVD case has a pretty significant spoiler about just what Harmonica's beef with Frank is, saying that he [[spoiler: "remembers how his brother was savagely tortured". Although it doesn't say outright ''who'' did it, it isn't difficult to put two and two together, and on top of that, it gives away one of the film's most shocking scenes]].
* TroubledBackstoryFlashback: Harmonica is relentlessly pursuing Frank, with a few flashbacks showing a blurred figure. [[spoiler:In the final showdown, we get a full flashback which reveals the blurred figure is Frank, who had Harmonica's brother hung from a bell and standing on his shoulders.]]
* {{Turncoat}}: Endemic among the bad guys. [[spoiler:Frank betrays Morton, and Frank's henchmen betray ''him'']].
* VehicleVanish: Harmonica makes his entrance this way, behind a train.
* VillainyDiscretionShot: Cheyenne killing his prison escort.
* WhamLine: [[spoiler:"Keep your lovin' brother happy."]]
* WhamShot: Cheyenne getting the drink he ordered, revealing to the camera his shackled wrists.
* WhammyBid: The five-thousand-dollar bid.
* WhiteShirtOfDeath: Most noticeable on Maureen (well, dress actually) and Timmy [=McBain=].
* WidowedAtTheWedding: Subverted with Jill. The story begins during her WeddingDay party with [=McBain=], but it's revealed they already married in New Orleans the month before.
* WouldHurtAChild: One of the earliest evil deeds Frank does is kill a child after this sinister excerpt of dialogue --
--> '''Goon:''' (about the boy) What are we gonna do with him, Frank?
--> '''Frank:''' (beat) Well, now that you've called me by name... (shoots the child)
** [[spoiler:Henry Fonda]], the actor who played Frank, was initially reluctant to take another a role in a western, having been in so many already and [[TypeCasting always playing one of the good guys]]. That is, until director Creator/SergioLeone told him, "Picture this: the camera shows a gunman from the waist down pulling his gun and shooting a running child. The camera pans up to the gunman's face and... it's [[spoiler:Henry Fonda]]." He signed on in a heartbeat (with some encouragement from a mutual friend).
* YouHaveFailedMe: Frank dispatches Wobbles when he finds out that Harmonica followed him.
* YouKilledMyFather: [[spoiler:Brother, actually.]]
