->'''Mutt Williams:''' You're a...teacher?\\
'''Indiana Jones:''' Part time.

The fourth film in the ''Franchise/IndianaJones'' series, released in 2008.

'''''Kingdom of the Crystal Skull''''' is set 19 years after the [[Film/IndianaJonesAndTheLastCrusade previous installment]], during the ColdWar, and begins with Indiana and his colleague, George 'Mac' [=McHale=] (Ray Winstone) being captured by Russian soldiers seeking a powerful artifact that the U.S. government is holding. Although the Russians, led by Irina Spalko (CateBlanchett) obtain the artifact (a CrystalSkull of unknown origin), Indy manages to escape after a harrowing experience at a nuclear testing site in Nevada.

However, the FBI accuse Indy of being a collaborator with the Russians, and he is even forced from his long-term teaching career due to the allegations. However, Indy quickly meets a leather-jacket wearing young man named "Mutt" Williams (Shia [=LeBeouf=]), who convinces Jones to go with him to South America and help him find an old friend.

Indy and Mutt's journey eventually lead them to reunite with Indy's old lover, Marion Ravenwood (Karen Allen), who had also been kidnapped by the Russians, and Professor Oxley (John Hurt), Jones' close associate who discovered the artifact and went slightly insane as a result. Now reunited with Marion, Indy decides to solve the mystery of the skull, which could have disastrous consequences.

''Kingdom of the Crystal Skull'' was finally put into production after having various ideas floated around [[SavedFromDevelopmentHell in the 1990's]]. The film took inspiration from the pulp science fiction stories of the 1950's, and was set during the ColdWar. The film also featured a score by JohnWilliams and creature effects by Creator/StanWinston (in one of his last projects).

The film received mostly positive reviews from critics, and earned $786 million from the worldwide box office. The movie also received criticism for its extraterrestial creature-influenced plot and an infamous scene where Indy uses a lead-lined refrigerator to escape a nuclear blast. Of course criticizing a part of a series with AllMythsAreTrue and ridiculous stunts wherever one looks in this manner is... [[FanDumb special]].

A fifth film is rumored to be in the works, although details are currently unknown.

----
!!This film provides examples of:
* ActionDuo: Indy and Mutt Williams.
* AdvancedAncientAcropolis: Akator.
* AffablyEvil: Irina Spalko.
* AluminiumChristmasTrees:
** The crystal skull and the story about returning all 13 of them to some place for... something. They even mention Mitchell-Hedges. What they don't mention is that the three known skulls are now proven hoaxes, as is the story of the 13 skulls.
** Artificial cranial deformation in ancient Native Americans.
** The Soviets' interest in parapsychology, although it was more popular before Stalin's death in 1953.
** And yes, the "Kung Fu Aztecs" guarding the graveyard ''did'' have a basis in fact; the Martial-Art of ''Rumi Maki'' (literally "Hard Hands") has been practised amongst Aztecs centuries before the arrival of Cortez. They developed a martial art like ''every'' other high culture.
* AmphibiousAutomobile: A GAZ 46 MAV (Soviet copy of the Ford GPA) is used as a getaway car down a river and over three waterfalls.
* AncientAstronauts: The titular "kingdom" of aliens is referenced as such, although it is never elaborated upon.
* ArbitrarySkepticism: Indy dismisses [[ArtifactOfDeath the Crystal Skull]] as "just a story". Like the Holy Grail and [[ArtifactOfDeath the Ark of the Covenant]], right? His skeptical attitude toward the Ark is also bit odd considering that he'd already been exposed to genuine supernatural phenomena in ''Temple of Doom'', but that's more of a continuity issue.
** Of course, he might have just been messing with his captors. Being uncooperative with the enemy seems to be a speciality of his. Or he knows this sort of thing is real but also knows that a lot of stories like that really are just stories.
* {{Area 51}}: It turns out that this (here called "Hangar 51") is where the U.S. [[SecretGovernmentWarehouse government stores]] most of the dangerous ancient phlebotinum that Indy finds. And [[BadassBookworm Indiana Jones himself]] [[spoiler:was called in to help investigate the Roswell Incident]].
** And it is also the final resting place of ''[[RaidersOfTheLostArk The Ark of the Covenant]]''
* [[ArtisticLicensePhysics Artistic License- Physics]]: No not [[ArtisticLicenseNuclearPhysics nuclear physics]] for the infamous fridge. Explosions are funny things where even a little cover can make a huge difference. Nor is radiation an automatic death sentence. Hurling a man in a metal box into the air several hundred yards though [[NotTheFallThatKillsYou is problematic for entirely different but more mundane different reasons.]]
* BadassGrandpa: Indy's age doesn't slow him down at all.
* BarBrawl: Indy orders Mutt to punch a man, instigating a brawl in the Malt Shop so they can escape.
* BeCarefulWhatYouWishFor: Indiana cast this literal {{foreshadow}} when Spalko is exposing her domination plans.
* BigBad: Irina Spalko.
* BiggerBad: Spalko works for the Soviet Government.
* BombproofAppliance: A lead-lined fridge is used to survive a nuclear bomb blast.
* {{Bowdlerise}}: In the Russian dub, all mentions of "Russians" and "Russia" were replaced with "Communists" and "USSR". However, Russian names and backgrounds of the villains were kept intact, thereby making the film more accurate -- Soviet intelligence personnel (who are the only ones portrayed in the film) came from [[SovietRussiaUkraineAndSoOn multiple republics]], not just Russia, even in this time period, like L. Beria, who as interior minister ''before'' the film's setting. They would certainly be party members or Soviet citizens. Note that even Irina Spalko is said to be from Ukraine not Russia.
* BrakeAngrily: Marion does this when she notices that Spalko is the back seat of the jeep she's driving during the jungle car chase.
* TheBrute: Dovchenko.
* BusCrash: It's stated that [[spoiler:Henry Jones Sr.]] passed away sometime between ''Film/IndianaJonesAndTheLastCrusade'' and ''Crystal Skull''. This is because [[spoiler:SeanConnery]] was offered a cameo role, but didn't want to come out of retirement. The same scene reveals Marcus Brody died shortly afterward, because Denholm Elliot had died shortly after making the third film.
* ButtMonkey: Mutt goes through a lot of abuse, as he gets punched by overprotective girlfriends, stung by scorpions, and knocked off moving Jeeps.
** Mac also qualifies; he gets beaten up and kidnapped prior to the film, gets shot in the foot and has his nose broken by Indy, and finally [[spoiler: he gets sucked through the interdimensional portal.]]
* CallBack: ''Lots.''
** The establishing shots of Marshall College (when Indy returns after being debriefed by the FBI) are replicated from the same shots seen at the beginning of ''Film/RaidersOfTheLostArk'' and ''Film/IndianaJonesAndTheLastCrusade'', down to the music, the passing car and a shot of the dean walking into the classroom where Indy is teaching.
** The music heard during the warehouse escape sequence is the exact same piece used during the escape from the Hovitos in ''Raiders''.
** During the graveyard sequence, a guard shoots a poisoned dart at Mutt that sticks in a shovel, much like the scene in ''Raiders'' where Indy's torch is hit by a dart as he's attempting to reach the golden idol.
** The scene where Indy, Marion and Mutt argue about personal issues before taking out a guard is identical to a similar scene in ''Film/IndianaJonesAndTheLastCrusade'' where Indy and Henry argue about their personal issues before taking out a pair of guards.
** Indy gets angry at Mutt when he realizes he brought him Oxley's note with him, just like how in ''Last Crusade'', his father was angry when he realized Indy brought the grail diary with him.
** The Joneses performing a motorcycle escape again.
** Indy finds an important clue on the floor at the last known location of Ox, just like in ''Last Crusade'', when Indy was at the Venice library, the last known location of his Dad toward the beginning.
** Mutt laughing at the Soviet spies after they crash, while Indy looks on unamused, is similar to how in ''Last Crusade'', Indy laughs after taking down a Nazi motorcyclist as his father looks unamused. Although Indy's unamused because they crashed into a statue of Marcus Brody.
** [[spoiler:Mac]] dies because of his greed, just like Elsa did in ''Last Crusade''. Indy asking him to give him a hand is also a CallBack to this scene.
** Indy and Mutt have a conversation at a malt shop. In ''Last Crusade'', Indy says the last time he and Henry Sr. had a drink together, it was (presumably) at a malt shop, as Indy says "I had a milkshake". This becomes more significant after [[spoiler:Indy and Mutt learn that they're, respectively, father and son.]]
* TheCameo: Along with the one in ContinuityNod below, Moses's staff from ''Film/TheTenCommandments'' is seen at the hangar.
* CanonImmigrant: Partial example. The Russians first interfered with Indy in one of the games before they were used for ''Crystal Skull''.
* CarloadOfCoolKids: In the opening scene, a hot rod full of teenagers paces the convoy of army trucks. The lead vehicle even races the hot rod for a little while.
* CasualDangerDialog: Doctor Jones pauses to give scholarly advice to a student after Mutt's motorcycle crashes through the college library. Bonus points for the obscure StealthPun; the advice given (while being hotly pursued by a couple of Communist mooks) is to read Vere Gordon Childe, a passionate and well-known Marxist.
* CharacterAgedWithTheActor: Lampshaded and part of the new {{EstablishingCharacterMoment}}s needed after the SequelGap. e.g Indiana fails one of his whip-antics.
* ChekhovsGun: Mutt's knife.
* ChekhovsSkill: Early on, Mutt establishes that he learned the art of fencing before dropping out of school. This comes in handy later when he discovers a pair of swords in the back of the group's escape vehicle during the forest chase scene, and uses one to spar with Spalko as the cars race through the forest.
* CityOfGold: Akator is the local name for the mythical lost city El Dorado.
* ColonelBadass:
** We learn Indy was made a Colonel in the OSS during World War II.
** Colonel Dr. Irina Spalko.
* ContinuityNod:
** [[spoiler:The Ark of the Covenant]] is revealed as Indy exits the warehouse after the truck chase sequence.
** Indy mentions to Mutt that he ran away from home and joined Pancho Villa during the Mexican Revolution when he was a teenager. This happened in the pilot episode of ''TheYoungIndianaJonesChronicles''.
** At one point, Indy tells Mutt that his plan to distract the Russians at the campsite is "intolerable", just like Henry Jones said several times to Indy in the previous film.
** In ''The Last Crusade'' Indiana teaches that seventy percent of all archaeology is done in the library. By 1957 his thinking has evolved and it's more in touch with his actions; he remarks that a good archeologist is the one who gets out of the library and does field work.
* CuttingTheKnot: When they uncover the hidden city Indy and company have a huge dramatic chase scene to avoid the angry natives. The Russians [[CurbStompBattle shoot those natives down]] so efficiently that they barely brake stride.
* DangerouslyGenreSavvy: Mac, when Indy is playing chicken in the warehouse CarChase.
-->"Don't get too clever, Boris. You don't know him... YOU DON'T KNOW HIM!"
** [[spoiler:Mac makes sure to plant the idea that he's just playing along with the Russians as a DoubleAgent after Indy is captured, as he knows there's a good chance Indy will turn the tables on them.]]
** When Indy hears about the aliens wanting to give them a gift, "a big gift", he instantly knows it's time to haul ass at full speed.
* DarkActionGirl: Irina Spalko.
* DeathByMaterialism: [[spoiler:Mac]], whose need to get as much gold and jewellery as possible during the temple collapse leads to him being unable to run as quickly when the ground starts collapsing.
* DecontaminationChamber: Radiation scrub-down right after nuking the fridge.
* DevelopmentGag: Oddly enough the gag actually calls back to the development of ''Film/BackToTheFuture'' -- originally, the climax of getting Marty [=McFly=] back, well, to the future, was that Doc Brown was going to take him and a refrigerator to an A-Bomb test, and let [[ILoveNuclearPower the bomb's effects send him back to his rightful time.]] However, Spielberg was uncomfortable with the idea, concerned that kids might climb into abandoned fridges to play-act the scene, and so asked Creator/RobertZemeckis to find a different approach, which he did once it proved too expensive to pull off. However, no good idea goes unpunished, as guess what iconic scene occurs in this movie?
* DinerBrawl: Indy and Mutt start a brawl in a diner in order to get away from the KGB.
* DirtyCommunists: The bad guys of the film. Spalko actually states that her obsession with it is due to [[spoiler:the aliens possessing a HiveMind]]. Just as Belloq desired the Ark of the Covenant because it is "a radio for speaking to God", Spalko wants to find the Kingdom for a [[spoiler:Commie AssimilationPlot.]] (As you might expect, Russia was ''very'' upset by this movie. [[WordOfGod Spielberg tried to justify using Russians as villains]] by saying that the United States didn't have any other enemies during the time period.)
* DoubleEntendre: Irina to Mutt: "You fight like a young man; eager to begin, quick to finish!"
* DoubleReverseQuadrupleAgent: [[spoiler: Mac. He betrays Indy in the beginning, "explains" it partway through by claiming to be a CIA double-agent, then betrays him ''again'' at the end.]] Indy [[LampshadeHanging lampshades]] this
-->'''Indy''': What, are you some kind of triple agent?!
-->'''[[spoiler: Mac]]''': [[NoExceptYes Nah, I just lied about being a double]].
* TheDragon: Antonin Dovchenko.
* DramaticAlienVTOL: The pyramid doubles as an alien ship.
* DressingAsTheEnemy: How the Russians arrive at the base checkpoint.
* EldritchAbomination: [[spoiler: The Aliens.]]
* EstablishingCharacterMoment: Lest anyone thought Indy lost his edge since ''Last Crusade'', we're immediately proven wrong:
-->'''Dovchenko:''' You recognize building, yes?
-->'''Indy:''' (deadpan) Drop dead.
-->(Dovchenko strikes Indy)
-->'''Indy:''' [[SarcasmMode I'm sorry, I meant "Drop dead,]] ''[[SarcasmMode comrade]]''."
* TheFifties
* FiredTeacher: Narrowly averted by the Dean, who gets Indiana "a leave of absence".
* FiveManBand:
** TheHero: Indiana Jones
** TheLancer: Mutt Williams [[spoiler:aka Henry Jones III]]
** TheBigGuy: George 'Mac' [=McHale=]
** TheSmartGuy: Professor Oxley
** TheChick: Marion Ravenwood
** SixthRangerTraitor: [[spoiler:Mac]]
* GainaxEnding: [[FanDumb Reviewers of the film have criticized the bizarre turn it takes after the first hour or so, including some bits of]] BeethovenWasAnAlienSpy, while the earlier films have just as much supernatural going ons.
* GenreShift / GenreThrowback: Where the previous three films were heavily based on the pulp adventure serials of the '30s and '40s, this one is derived in part from the pulp sci-fi of the '50s.
* GiantMook: Igor Jijikine as the big Russian colonel, Dovchenko.
* GoryDiscretionShot: The massacre of the American soldiers at the beginning of the film by the Russians is only seen in a distant shot after most of them have been downed.
** Ditto for the Central American natives. The only sign they or the Americans have been shot are [[PrettyLittleHeadshots tiny, bloodless bullet holes]] in their backs.
* HeelFaceRevolvingDoor: [[spoiler:Mac]], who switches sides and motives constantly throughout the film. [[spoiler:He's apparently helping the Russians because he's "a capitalist", yet he's also a double mole for the CIA]]. Lampshaded as a DoubleReverseQuadrupleAgent.
* HijackedByJesus: Averted:
-->'''Mutt:''' (regarding elongated skulls on skeletons) Why are they like that?\\
'''Indy:''' Incans would bind the heads of their infants with rope.\\
'''Mutt:''' (horrified) Why would they do that?\\
'''Indy:''' To honor the gods.\\
'''Mutt:''' No! No! God's head does ''not'' look like that!\\
'''Indy:''' That depends on who your god is.
* HollywoodMagnetism: When Indy needed to find the location of a magnetic crate, he threw gunpowder in the air and watched which way it moved. Later on, this trope is lampshaded when an object attracts gold coins, which are decidedly ''not'' magnetic.
* IJustShotMarvinInTheFace: When told to drop his gun, Indy (purposely) manages to shoot one of the communists in the foot when it hits the floor.
* IKnowKarate: Subverted. After Mutt grabs the titular cranium, Spalko busts out previous unseen and unmentioned martial arts moves -- and ''sucks'' at it. At most, it seems like it's annoying Mutt.
* ImprobableCover: Indy survives a nuke by hiding in a refrigerator.
* ImprovisedWeapon: Mutt uses the bagged Crystal Skull itself to clobber a Russian soldier a few times.
* InNameOnly: The crystal skull(s) have almost nothing in common with the Mitchell-Hedges CrystalSkull legend.
* IndyPloy: Lampshaded
-->'''Mutt''': What's he gonna do now?
-->'''Marion''': I don't think he plans that far ahead.
* InevitableWaterfall: Three of them. One after another.
* IronicEcho: "Hold this" and throwing someone a skeleton.
* {{Irony}}: "I'm a capitalist...and [[DirtyCommunists they]] pay."
* ItsPronouncedTropay: For some reason, ''college professor'' Dr. Henry Jones pronounces nuclear "nuke-yoo-lur".
** He's an ''archaeology'' professor. Consider that the technique of carbon dating only debuted ''eight'' years before the events of the film and use of geophysics for archaeological surveys are only just getting off the ground in the United Kingdom, Indy has barely needed to study physics for most of his career.
* KarmicDeath:
** [[spoiler:Irina Spalko's]] need for knowledge ends up being [[spoiler:her]] downfall when the alien [[spoiler:reads her mind and judges that she would use the information for evil, before burning her alive from the inside-out]].
*** Another interpretation is that [[spoiler:she got [[BeCarefulWhatYouWishFor exactly what she asked for]], but it was just too much for her [[MySkullRunnethOver puny human brain]] to hold]].
** Early on, [[spoiler:Mac turns against Indy]] while claiming he's a "capitalist". This turns out to be his downfall, as he dies when [[spoiler:his love of material goods makes him too slow to escape the collapsing temple]].
* KleptomaniacHero / GraveRobbing: Subverted; Indy is about to keep an ancient knife but a severe [[FacialDialogue look]] by Mutt makes him put it back.
* LastWords / FacingTheBulletsOneLiner: Parodied hard.
-->'''Spalko''': No [[DefiantToTheEnd defiant last words]], Dr Jones?
-->'''Indy''': I like Ike.
-->'''Dovchenko''': Put down gun.
* LateArrivalSpoiler: In the film, Marion's [[TheReveal reveal]] a third of the way through is meant to take Jones (and the audience) by surprise. Of course, that didn't stop Paramount from including the character on the official poster for the film and heavily publicizing Karen Allen's involvement with the project.
** Her name also appears in the credits shown during the opening scene.
* LeaningOnTheFourthWall: At least twice during the scene with the ants, an ant is squished and the goo that shoots out lands on the camera.
** There is also water splashed on the camera when they fall down the waterfall.
* LighterAndSofter: PrettyLittleHeadshots, [[RedLetterMedia only one murder by Indiana]], cute monkeys, cute prairie dogs...
* LikeFatherLikeSon: A central motif of the movie.
* LogoJoke: Cutting from the Paramount mountain to a prairie dog mound.
* LukeYouAreMyFather: [[spoiler:Mutt]]. Oddly enough, early promotional materials claimed that the film would feature [[spoiler:Indiana Jones and son on an adventure]]. This was retconned into [[spoiler:Mutt being a young friend just so they could try and surprise audiences during the film]].
* MadeOfIron: Despite being older, Indy endures more punishment than ever before. He flies backwards into a truck and crashes through the windshield, survives inside a lead-lined fridge when it's tossed end-over-end out of the blast zone and tries to beat TheDragon (who's seemingly larger than he is) while getting punched repeatedly. The rest of the cast (especially Oxley) exhibit this when they survive the trip over three waterfall drops with nothing more than shaken nerves.
* MaltShop
* {{Mayincatec}}: A Maya-style temple and AncientAstronauts giving the Maya their technology.
* MeaningfulName: "Mutt" Williams' nickname is [[spoiler:an early hint that he's related to Indiana, who took his own nickname from his dog's name.]]
** [[spoiler:Of course, Mutt claimed that he made the nickname up himself, and he had never known that Indy was his father until TheReveal (or even who he was until the beginning of the film) so it was probably just a coincidence, at least in-story.]]
* MindRape: The crystal skull aliens killed the villain with knowledge.
** -and tearing her a new hole in spacetime.
* MisterSandmanSequence: Right at the start; defiant youngsters on the road taunting other drivers, with Elvis' Hound Dog as the soundtrack.
* TheMole: [[spoiler:Mac]]: ''"I'm a capitalist. And they pay."''
* MoodDissonance: In the Nevada bomb testing scene, the mood quickly goes from comical (Indy stumbles over mannequins and falls over a bicycle placed on the road) to disturbing (the nuclear blast countdown and Indy's reaction to it).
* MotherRussiaMakesYouStrong: The GiantMook.
* MsFanservice: [[TheBaroness Irina]] [[EvilIsSexy Spalko]]
* MySkullRunnethOver: The climax.
* NeverBringAKnifeToAGunFight: After-the-fact advice given to Mutt by Indiana.
* NoOneCouldSurviveThat: Exactly how Mac survived the head on collision with Indy is ''never'' explained?
* NoodleIncident: What Indiana did as an OSS intelligence officer DuringTheWar implies the existence of a full noodle warehouse. Many medal-worthy actions are alluded to and a Berlin cover mission is invoked by Mac. Plus his involvement in the RoswellIncident.
* ObfuscatingDisability: Indiana openly asks Oxley -- surrounded by Russians -- if he is [[PlayingSick faking it]].
* OhCrap: The whole group of heroes when the truck they're driving goes over a waterfall. Then it happens ''again'' as they realize it's not just one, but '''three''' sequential waterfalls.
* OlderAndWiser: Indy, more-or-less. The years haven't ''completely'' cured his reckless nature, but they have mellowed it a bit.
* OneSteveLimit: Subverted. Mutt claims his mom knew Indy, but only gives her name as "Mary Williams". That doesn't do anything for [[TheCasanova Indy]]: "There've been a ''lot'' of Marys, kid."
* OutrunTheFireball: {{Subverted|Trope}} -- the bad guys try this, and get [[spoiler:nuked.]]
* PaintedOnPants: Irina Spalko. For the most part, her whole outfit is just tight enough to have a fanservice feel to it, but there are moments where her pants look painted-on tight, like when she [[spoiler:crushes a huge ant with her knees.]]
** Played straight with Marion.
* PassingTheTorch: {{Subverted}}. At the end of the film, a gust of wind blows Indy's hat to Mutt's feet, the idea being that Indy is going to retire from archaeology and Mutt is gonna take his place. But as Mutt is about to put the hat on, Indy scoops it out of his hands and puts it on; Indy's never gonna quit looking for treasures.
* ThePiratesWhoDontDoAnything: Lampshaded:
-->'''Mutt:''' (''incredulously'') You're a teacher?\\
'''Indy:''' Part-time.
* PreAsskickingOneLiner: "I like Ike."
* PrettyLittleHeadshots: All of the bullet wounds on ''rifle'' victims are tiny, black, bloodless holes, even on natives wearing no clothes.
* PunchPunchPunchUhOh: Wouldn't be an Indy movie without it, as Indy fights Dovchenko while surrounded by man-eating ants.
* PunctuatedForEmphasis:
** "[[CateBlanchett You vill]]. [[LargeHam Help us]]. [[FakeRussian Find it]]."
* QuicksandSucks: Indy and Marion get caught in it, although Indy explains that it's actually "dry sand". It's also when [[spoiler:Marion tells Indy Mutt is his son]]. TruthInTelevision though as very dry fine sand is actually very fluid. It's only when wet or rough that sand will stick.
* RealityEnsues: The first clue that the Crystal Skull is no ordinary magnet is Mutt's reminder that gold wouldn't stick to one.
** This could also explain the way the gunpowder finds its way to the skull in the opening sequence, with Indy not applying shoddy Hollywood science but exploiting the unique property he knew about from his work with the skull.
* RedScare: Irina Spalko and the Russians.
** This also is shown in the rampant paranoia of the time, with the two FBI agents who question Indy insinuating that he's a communist sympathizer and traitor, even though it's also pointed out that he's both a War Hero and one of the most highly decorated people in the entire country.
*** Which is emphasized by his former CO, General Ross, who clearly believes that the obsession over the Red Scare is absurd, and tries to convince them that Indy is innocent. It doesn't help much. Though the worst Indy got was losing his job as a college professor.
* ReliablyUnreliableGuns: Invoked; when ordered by Dovchenko to [[ExactWords drop his gun]], Indy tosses it on the ground and it goes off, hitting Dovchenko in the foot.
* SecretLegacy: [[spoiler:Henry Jones III]] has at least a passing interest in archaeology as well, although part of that seems to be that his mother likes hanging around with archaeologists since her father was [[AdventureArchaeologist one]] as well.
* SequelGap: Both in-universe and in real life, 19 years have passed between the movies.
* ShapedLikeItself "Their treasure was knowledge. Knowledge was their treasure."
* ShoutOut:
** WordOfGod says Professor Harold Oxley was modeled after Ben Gunn from ''TreasureIsland''.
** Mutt's BadassBiker image is lifted from MarlonBrando in the ''Film/TheWildOne''.
* SlowElectricity: In the warehouse scene, the lights turn on one at a time.
* SmolderingShoes: All that's left of [[spoiler:Spalko]] after her KarmicDeath is a smoking pair of boots.
* SmugSnake: [[spoiler:Mac]].
* SpecialEffectsBeefUp
* SuspiciouslySimilarSubstitute: Jim Broadbent's character stands in for Marcus Brody.
* TakeMyHand: Subverted. Indy tries this with his whip to save [[spoiler:Mac]] during the final escape sequence, but [[spoiler:Mac]] tells him he'll be alright and lets go, getting sucked into the portal in the process.
* ThatRussianSquatDance: Done by Russian soldiers around a campfire.
* TookALevelInBadass: Marian has graduated from throwing the occasional punch at her captors to [[spoiler:driving an amphibious transport off a cliff and ''onto a tree'', then letting the tree snap back and smack into the cliff-climbing Mooks behind her]].
** She was pretty badass in "Raiders", though. She shot that guy in her bar, and she took out a whole truck full of soldiers with an aircraft-mounted machine gun.
** Indiana as well. He was an ActionSurvivor in the first three films who got by on luck and [[TheDeterminator determination]], but with an extra nineteen years of adventuring under his belt, Indy's actually gotten good at being an ActionHero.
* TouchedByVorlons: [[spoiler:Oxley and Irina. The latter's brain painfully overloads from the aliens granting her wish - knowledge of everything.]]
* TrilogyCreep: ''The Last Crusade'' ends with Indy & co. RidingIntoTheSunset because Spielberg thought it would the end. He later admits in the DVD interviews for ''Crystal Skull'' that he initially had no interest in reviving the franchise until he was convinced by George Lucas to add an additional instalment.
* UnderTheTruck: The motorcycle goes under a few library desks.
* UnusuallyUninterestingSight: Indy gets involved in a motorcycle chase that crashes into the library of the school he works at. One student only notices this in the context of "hey, there's the professor, let's ask him about that question on the homework before he disappears for weeks again".
* YouFailGeographyForever[=/=]YouFailHistoryForever
** Coastal Nazca is placed in Los Anfes.
** Indy learning quechua, an Andean language, from Mexican PanchoVilla.
*** Possibly justified, since he states he learned it from some of Villa's men, not Villa himself.
* ViolentlyProtectiveGirlfriend: When Indy tells Mutt to start a fight by punching a random guy, the first person to hit Mutt back is the victim's girlfriend.
* WilhelmScream: By a student with glasses when Indy and Mutt crash through the library on a motorcycle.
* WouldntHitAGirl: But, he would toss one from a moving truck.
