->'''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 UsefulNotes/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 (Creator/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 out of 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 UsefulNotes/ColdWar. The film also featured a score by JohnWilliams and creature effects by Creator/StanWinston (in one of his last projects).

A fifth film is in the works, set to be released in 2019 with Harrison Ford reprising his role as Indy. Further details on the project are unknown.

!!This film provides examples of:

* ActionDuo: Indy and Mutt Williams.
* AdvancedAncientAcropolis: Akator.
* AffablyEvil: Irina Spalko.
* AgonyOfTheFeet: In the warehouse at the start of the film, Dovchenko tells Indy to put his gun down. He does, by dropping it to the ground in such a way that it goes off, hitting Dovchenko in the foot.
* 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. Though the first examination to prove this happened in 1967, a decade after the film's setting.
** Artificial cranial deformation in ancient Native Americans.
** The Soviets' interest in parapsychology, although it was more popular before Stalin's death in 1953.
** The derided "Kung Fu [[{{Mayincatec}} Aztecs]]" guarding the Andean graveyard. Pre-hispanic Andeans did actually practice a native martial art called ''Rumi Maki'' ("Stone Hand"), complete with a grading system of skill and focuses on combinations of hand strikes supplemented by rapid kicks, just as portrayed in the film.
** Not only does [[http://en.wikipedia.org/wiki/Dry_quicksand dry sand]] of the type Indy and Marion get caught in exist, it's depicted relatively accurately; the different formation between quicksand and dry sand means that they follow different principles.
* AmusingInjuries: Indy breaking Mac's nose. Well, he ''did'' warn him...
* AncientAstronauts: The titular "kingdom" of aliens is referenced as such, although it is never elaborated upon.
* ArbitrarySkepticism: Indy dismisses the CrystalSkull as "just a story". Like the HolyGrail and TheArkOfTheCovenant, 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 specialty 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. Just because ''some'' supernatural tales are real in the Indyverse doesn't mean ''all'' of them are.
* {{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 ''[[Film/RaidersOfTheLostArk The Ark of the Covenant]]''
* ArtisticLicenseBiology: The "Rat Snake" used to rescue Indy and Marion is really a Papuan Python. Rat snakes do not grow that big. Even Indy lampshaded that one when Mutt tried to assure him.
--> '''Indy:''' Rat Snakes aren't that big.\\
'''Mutt:''' This one is, alright?
* ArtisticLicenseGeography[=/=]ArtisticLicenseHistory
** Coastal Nazca in the Andes.
** Indy learning quechua, an Andean language, from men in Mexican Pancho Villa's army. Not impossible, but pretty unlikely. Nahautl would've been more likely.
** The map showing the journey to Peru shows a country called Belize - it was British Honduras until 1973. While the name "Belize" ''does'' date to at least the 17th century (it comes from the Belize River), any 1957-vintage map would've used the then-official name British Honduras.
* ArtisticLicensePhysics: No, not [[ArtisticLicenseNuclearPhysics nuclear physics]] for the infamous fridge. Explosions are funny things where even a little cover can make a huge difference, though an explosion that destroys everything else may or may not leave a refrigerator intact--those old ones ''are'' amazingly tough. Nor is radiation an automatic death sentence -- it can take days to succumb to radiation poisoning after exposure to a lethal dose, and the exposure can be mitigated if you get decontaminated fairly soon (hence Indy being stripped naked and scrubbed down), depending on the type of radiation you've been exposed to. However, hurling a man in a metal box into the air several hundred yards [[NotTheFallThatKillsYou is problematic for entirely different but more mundane reasons.]]
* 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, making Joseph Stalin the bigger bad.
* BigWhat: Indy to Dean Stanforth when he's told he has to take a leave of absence. It's loud enough for his students to hear it through the classroom door.
* 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". It's not much of a change because the American characters use "Russian" in the original dialogue out of convenience to begin with: Spalko is from eastern Ukraine, and her right hand man Dovchenko is from Siberia in the [[AllThereInTheManual suplementary material]] (and judging by his surname, of Ukrainian descent).
* 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 Henry Jones Sr. passed away sometime between ''Film/IndianaJonesAndTheLastCrusade'' and ''Crystal Skull''. This is because Creator/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.
** Doctor Jones is still teaching from Michaelson, Chapter 4.
** The music heard during the warehouse escape sequence is the exact same piece used during the escape from the Hovitos in ''Raiders''.
** Indy gives Mutt a quick summary of his time with Pancho Villa as an explanation for why he knows a Central American native language.
** 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.]]
** [[spoiler:After their wedding vows, Marion possessively takes Indy's arm in exactly the same way she did at the end of ''[[Film/RaidersOfTheLostArk Raiders]]''.]]
* 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 {{Establishing Character Moment}}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 ''Series/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.
* CruelAndUnusualDeath: Like in previous movies, the GiantMook and the BigBad suffer these fates. Dovchenko gets devoured by a swarm of man-eating ants. They even take his carcass to an anthill. [[spoiler:Spalko's brain incinerates, making fire come out of her eyes, before she's disintegrated.]]
* CrystalSkull: The current MacGuffin - albeit it's not even a human skull.
* 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 break stride.
* DarkActionGirl: Irina Spalko.
* DeathByMaterialism: [[spoiler:Mac]], whose need to get as much gold and jewelry 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.
* DevouredByTheHorde: When a ton of man-eating ants appears, they take out several Russian soldiers, but [[spoiler: Dovchenko suffers the most when several of those ants goes inside his mouth and then they drag him into an anthill.]]
* 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 TheArkOfTheCovenant because it is "a radio for speaking to God", Spalko wants to find the Kingdom for a [[spoiler:Commie AssimilationPlot.]]
* DisappearedDad: [[spoiler:Indy turns out to have been one to Mutt.]]
* 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]]:''' [[DistinctionWithoutADifference 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]]''."
* ETGaveUsWiFi: According to a wall painting Indy finds, the aliens came down and taught humans agriculture and irrigation.
* TheFifties
* FiredTeacher: Narrowly averted by the Dean, who gets Indiana "a leave of absence".
* FiveManBand:
** TheLeader: Indiana Jones
** TheLancer: Mutt Williams [[spoiler:aka Henry Jones III]]
** TheBigGuy: George 'Mac' [=McHale=]
** TheSmartGuy: Professor Oxley
** TheChick: Marion Ravenwood
** SixthRangerTraitor: [[spoiler:Mac]]
* ForScience: Spalko's motives start out as a Communist AssimilationPlot, but by the end she seems to care more about raw knowledge for the sake of itself - ''all'' of it. [[spoiler: It proves to be a bit too much.]]
* {{Foreshadowing}}:
** Mutt reveals in the malt shop his mother's name is Mary. Guess who she turns out to be?
** Pretty much everything Oxley says [[spoiler:while raving comes back as important later as it helps lead the main characters to Akator.]]
** A quick one near the beginning; when the door to Hanger 51 is opened, the Lost Ark's musical cue is briefly heard. Turns out the hanger is where the US Government stashed it, as revealed by its broken crate.
* GainaxEnding: 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.
* 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.
* GreyAndGrayMorality: The WebVideo/RedLetterMedia review pegs this as one of the problems with the film. The other films had BlackAndWhiteMorality, with either ThoseWackyNazis or a ReligionOfEvil cult as the villains. In this movie, the Americans and Russians are portrayed as NotSoDifferent and yet we're still expected to be rooting against the Russians.
* 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.
** According to a ''Website/{{Cracked}}'', [[http://www.cracked.com/article_21752_7-things-you-learn-surviving-atomic-blast_p2.html interview ]] with a Hiroshima survivor, said interviewee's granpa survived the blast by hiding in a freezer, albeit under slightly different circumstances.
** Given the frige is lead, tham and the house would have absobed much of the impact of the blast, so itís possible Indy Could have survived.
* ImprovisedWeapon: Mutt uses the bagged Crystal Skull itself to clobber a Russian soldier a few times.
* IndyPloy: Lampshaded.
-->'''Mutt''': What's he gonna do now?\\
'''Marion''': I don't think he plans that far ahead.
* InNameOnly: The crystal skull(s) have almost nothing in common with the Mitchell-Hedges CrystalSkull legend.
* InevitableWaterfall: Three of them. One after another.
* IronicEcho: "Hold this" and throwing someone a skeleton.
* {{Irony}}: "I'm a capitalist...and [[DirtyCommunists they]] pay."
* ItIsPronouncedTroPAY: For some reason, ''college professor'' Dr. Henry Jones pronounces nuclear "nuke-yoo-lur".
* KarmaHoudini: The two FBI agents that blacklisted Indy never received any comeuppance.
* 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, [[WebVideo/RedLetterMedia only one murder by Indiana]], cute monkeys, cute prairie dogs...
** Then again..."BIG DAMN ANTS!"
* 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 to surprise audiences during the film]].
* MacGuffinDeliveryService: The villains invoke this trope to do the exact same thing the heroes want to do!
* 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: It is set in the 50s, after all. And there it happens a BarBrawl.
* {{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.]]
* MeaninglessMeaningfulWords: By the end, Oxley delivers a gem that is still [[ArtisticLicenseAstronomy tormenting the astronomists]] as of today :
-->'''Indy:''' Where did they go? Space?\\
'''Oxley:''' Not into space, into the space between spaces.[[note]] [[Film/{{Inception}} A space ''within'' the space]]; however, George Lucas explained that given the aliens are "interdimensional beings", it is whatever exists between our universe and theirs.[[/note]]
* MindRape: The crystal skull aliens killed the villain with knowledge. And tearing her a new hole in spacetime.
* MisplacedWildlife: The ants are recognized by Indy as "[[https://en.wikipedia.org/wiki/Siafu Siafu]]", who live across the Atlantic in Africa. The Brazilian dub\subtitles fixes with a similarly named one that does live in the Amazon, [[https://en.wikipedia.org/wiki/Atta_(genus) "Saúva"]], even if that opens another ArtisticLicense given those ants are leafcutters. To be fair, Indy might just be stating their assumed danger based on an ant he's more familiar with rather than saying that these ''are'' an African species that somehow ended up in South America.
* 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.
* 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.
** During Indy's escape from the warehouse, [[spoiler:Mac]] gets one when he realises the car he's in is on a collision course with Indy's, and is going to crash.
** Indy gets one when a carload of Russians looking for him [[spoiler:in the nuclear test site]] drive off without him, [[spoiler:leaving him stranded in the middle of a nuclear test site ''with less than twenty seconds to go before detonation''.]]
* 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}} -- a car of 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.
* PortraitPaintingPeephole: A variation. While in the Akator temple, a pair of eyes move in a skull relief on the wall.
* 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:
** "[[Creator/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 is also 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.
*** Paranoia? The Communists can invade even a nuclear test site. Seems [[TheCuckoolanderWasRight McCarthy was right...]] - in-universe.
* 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 ''Literature/TreasureIsland''.
** Mutt's BadassBiker image is lifted from Creator/MarlonBrando in the ''Film/TheWildOne''.
** Harrison Ford gets to say [[Franchise/StarWars "I have a bad feeling about this"]] once again. [[spoiler: Bonus points for being inside a spaceship at the time.]]
* 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]].
* SpecialEffectsEvolution: Been made 19 years after The Last Crusade, the fourth installment had a lot more CGI used in its action sequences.
* SuspiciouslySimilarSubstitute:
** Jim Broadbent's character stands in for Marcus Brody.
** George 'Mac' Mc Hale is essentially a replacement for Sallah, a fan favorite character who is totally absent from this movie. Mac's character is introduced as if we already knew him from previous installments; a lot of dialog refers to his and Indy's shared past (which happened in-between movies); [[spoiler: and we are clearly supposed to care about his change of alignment from good to evil, even though we never actually got to know him first]].
* 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.
* TakeTheWheel: Said by Indy to Marion twice during the jungle chase. Mutt complains the second time. "No fair! She got to drive the truck!"
* TemptingFate: When Indy and Marion get caught in the dry sand pit, he assures her it will be find so long as there isn't an air pocket. He doesn't even get to finish that thought before one bursts from them disturbing the sand, causing them to sink faster. Then a second one goes off.
* ThatRussianSquatDance: Done by Russian soldiers around a campfire.
* TokenEvilTeammate: Mac, with a side of ChronicBackstabbingDisorder.
* TookALevelInBadass: Marion 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.
* TheMountainsOfIllinois: There are no mountains or cliffs in the Peruvian amazon jungle.
* TouchedByVorlons: [[spoiler:Oxley and Irina. The latter's brain painfully overloads from the aliens granting her wish - knowledge of everything.]]
* TreeBuchet: Done to fend off a jeep of Russians.
* TrilogyCreep: ''The Last Crusade'' ends with Indy & co. RidingIntoTheSunset because Spielberg thought it would be 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 installment.
* 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".
* 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.
** This also applies to Marion as she manages to get Indy away from the Russians using an amphibious vehicle and a tree to knock them down as they were scaling the cliff.
* WeNeedADistraction: As Russian operatives try to take Indy and Mutt at the maltshop, Indy instructs Mutt to punch a random guy, thereby starting a DinerBrawl that distracts the operatives.
* WhamLine: [[spoiler:"He's your son."]]
* WhyDidItHaveToBeSnakes: When Indy and Marion are trapped in a dry sand pit, the only rescue line Mutt can find is a huge rat snake. Indy is reluctant to be rescued as such, eventually demanding they call it a rope to get him to grab it.
* WilhelmScream: By a student with glasses when Indy and Mutt crash through the library on a motorcycle.
