->''My God, it's full of stars!''

''2010: The Year We Make Contact'', directed by Peter Hyams and released in 1984, is the film adaption of ''2010: Odyssey Two'' by ArthurCClarke (published 1982). It is the sequel to ''TwoThousandOneASpaceOdyssey''. Following the continuity established by that movie rather than the original novel (for the most part, anyway), it is about the second manned mission to {{UsefulNotes/Jupiter}}, following up on the mysterious disappearance of David Bowman aboard the ill-fated ''Discovery'' mission nine years earlier.

Dr. Heywood Floyd (Roy Scheider), an astronomer who took the blame for the failure of the ''Discovery'', is tapped to go on the mission along with two other U.S. scientists -- engineer Dr. Walter Curnow (John Lithgow), who is tasked with boarding ''Discovery'' and restoring its systems; and computer scientist Dr. R. Chandra (Bob Balaban), who designed the H.A.L. 9000 and is seeking to answer the question of why it malfunctioned and tried to kill its crew.

Their mission is complicated by the fact that they are traveling aboard a Soviet spaceship, the ''Alexei Leonov'', whose crew is not at all friendly to their presence and may be operating under a completely different set of orders. In addition to exploring Jupiter and salvaging ''Discovery'', they must also try to solve the mystery of the Monolith, an enormous alien artifact orbiting the planet that is apparently connected with Bowman's disappearance. And of course, the creators of the Monolith have an agenda all their own, one that might alter the future of humanity forever.

The film ''2010'' was viewed by some as a GenreShift due to the change of directors and tone. It's much more of an action film, concentrating on the conflicts between the Russian and American crews and the dangers they face in their exploration of Jupiter. It follows the plot of the novel ''2010'' fairly closely, although the ColdWar-becoming-hot aspect is completely invented for the film and the time scale dramatically compressed.

The novel has two more sequels in Literature/{{the Space Odyssey series}}: ''2061: Odyssey Three'' and ''3001: The Final Odyssey''.

----
!!This novel and film provide examples of:

* AdaptationDistillation: Depending on your point of view, the ColdWar tension either makes the movie much more dramatic or is completely superfluous to the plot. The time scale of the events in the book is heavily compressed -- it's more dramatic when you have two days to get away than two weeks. The Chinese spaceship ''Tsien'' and its subplot regarding the Europa landing is completely removed in the movie, replaced by the ''Leonov'' detecting life signs on Europa and sending an unmanned probe. Other less relevant subplots are removed entirely, such as Floyd's marriage break-up and the romantic relationships between the crew; while [[spoiler:Max's death during an EVA to the Monolith]] was added for the film.
* AFormYouAreComfortableWith: When Bowman (as the Star Child) returns to give a warning to Floyd, he creates a projection of himself as a human to give Floyd something to talk to.
* AIIsACrapshoot: Deconstructed. The reasons for HAL's "malfunction" are thoroughly explored and it turns out he was acting in a way that, to him, was completely logical. [[spoiler: Since his core function is to freely disseminate information with as much accuracy as possible, being ordered to conceal the existence of the Monolith caused a LogicBomb in his program. To solve it, HAL concluded that if he killed the crew, there would be no-one left for him to lie to, thus allowing him to continue on with the mission by himself.]]
* AllThereInTheManual: The novel contains a lot more story details than the film, of course, but these details fill in a number of {{Plot Hole}}s, the largest of which is why Floyd is unable to provide evidence of Bowman's visitation and why HAL doesn't remember it (Bowman erased it from HAL's memory).
** Not to mention "My God, it's full of stars!" Those who only saw the film ''2001'' were completely confused by this final message by Bowman that they couldn't recall him saying.
* Music/AlsoSprachZarathustra: Since ''2001,'' this may be the ''only'' movie to use "Zarathustra" without irony or humor.
* ApocalypticLog: The last survivor of the Chinese expedition in the novel broadcasts what happened when they encountered life on Europa.
* ArcWords: Compare Dr. Chandra's answers for the same question from SAL and HAL.
-->'''SAL''': Will I dream?\\
'''Dr. Chandra''': Of course you will. All intelligent beings dream. Nobody knows why.

-->'''HAL''': Dr. Chandra, will I dream?\\
'''Dr. Chandra''': I don't know.
* ArtificialGravity: Averted in the novel and used somewhat schizophrenically in the movie: the rotating environment module of the ''Leonov'' was apparently made up by the art team so they could justify having the actors walking normally on the set, even though it doesn't make sense ''at all'' from a design standpoint. The novel states and some filmed scenes imply that the astronauts use Velcro-soled shoes to help them stay "upright".
** The scene when Floyd demonstrates docking the two ships by suspending pens in mid-air definitely implies the bridge of the ''Leonov'' to be a zero-G environment.
* ArtisticLicensePhysics:
** SelectiveGravity: On the bridge, Floyd uses two pens floating in microgravity to illustrate how the spaceships can escape from Jupiter. Only ''the pens'' are floating - everyone around the demonstration is ''standing on the floor''.
** You can try to explain the problem of gravity on the bridge by saying everyone's wearing magnet-soled shoes (as in the original movie - though magnetic shoes don't create gravity for the rest of the body), but you can't get around the scene where Floyd offers Kirbuk the squeezebottle of bourbon, because the liquid behaves like it's under gravity.
** Although the depictions of Jupiter and Io were based on Voyager photos (see ShownTheirWork), most people don't realize that Voyager's photos as they're usually published are in false color: the color saturation is heavily exaggerated, especially for reds, and this color scheme is carried through in the movie.
* AscendToAHigherPlaneOfExistence: Bowman is back as the Star Child, after being forcibly ascended by the SufficientlyAdvancedAliens in ''2001''. At the very end, and by his request, [[spoiler:HAL joins him]].
* AuthorAppeal: Clarke's interest in alien aquatic life, such as on Europa, probably comes from his scuba-diving hobby. For ''2001'' he wrote a long passage about Bowman in his pod passing through an ocean on an alien world, which was cut out of that novel but included in ''The Lost Worlds of 2001''.
* BiggerOnTheInside: The ''Leonov'' isn't so much bigger on the inside, like the ''Discovery'' was in ''2001'', but rather its interior sets are entirely the wrong shape to fit into its hull. The sets looked like they were all built on the same level to facilitate WalkAndTalk shots.
* BinarySuns: At the end of the story.
* BollywoodNerd: UnbuiltTrope. Clarke, who lived in Sri Lanka, made Dr. Chandra an Indian computer scientist in the novel before it became a popular stereotype. This is erased in the film, with Dr. Chandra portrayed by a white actor.
* BrickJoke: [[spoiler:Floyd tells Curnow to hide the "kill switch" in a place that Chandra won't find it. Afterwards Chandra hands back said kill switch, saying he thought they'd try something like this and it wasn't hard to find.]]
* CallBack: Peter Hyams tried to make this movie as different from ''2001'' as possible, with a few exceptions --
** "Music/AlsoSprachZarathustra" and Ligeti's [[OminousLatinChanting "Lux Aeterna"]] appearing on the soundtrack.
** Bowman's use of {{Offscreen Reality Warp}}s as his age shifts back and forth when talking to Floyd, the only scene that actively tried to imitate the style of ''2001''.
** The steadily accelerating beep of the space probe's radar signal as it approaches the life signs on Europa, similar to the scene in ''2001'' when Bowman locates Poole's body in space.
** The reflection of the pod's controls on Max's helmet.
** HAL telling Bowman "I'm afraid."
* ChekhovsGun: In the novel, Bowman's discovery that Jupiter's core is "a diamond as big as the Earth" sets up major plot points for ''2061''.
* ClarkesThirdLaw: Specifically [[InvokedTrope invoked]] with respect to the aliens' technology.
* ColorCodedCharacters: While HAL 9000's eye is of course red, SAL 9000's is blue. Also an inversion of PinkGirlBlueBoy.
** American spacesuits are white; Soviet spacesuits are silver.
* ComputerEqualsMonitor: Before discussing HAL's malfunction with the crew, Chandra tells HAL, "If you will excuse us, we wish to have a private conversation." He hits a few keys on the HAL console in ''Discovery'''s pod bay and the monitor turns off. However, ''the red light in HAL's camera lens is still on.'' And if you really wanted to be paranoid, there's still another HAL camera looking through the window of the pod bay control room.
* ConstantlyCurious: Christopher Floyd, when he asks his father why he needs to go into hibernation.
* CreatorCameo: Arthur C. Clarke appears as a man on a park bench in front of the White House.
* CreatorInJoke: In one scene, the cover of ''Time'' magazine appears with portraits of Clarke and Kubrick as the U.S. president and Soviet premier, respectively.
** ArtisticLicenseLinguistics: However, during the war announcement, Millson says the Soviet premier is named Yulanova, which is a woman's surname.
* CreepyMonotone: HAL's back... [[CyberCyclops as is his "eye"]].
* CutTheJuice: Floyd and Curnow install a cutoff switch in HAL's wiring as a safeguard against a repeat of the ''2001'' incident. Subverted when [[spoiler:Chandra reveals that he anticipated their ploy and removed the device]].
* DawnOfAnEra: "The next day, the President of the United States looked out of the White House window, and the Premier of the Soviet Union looked out of the Kremlin window, and saw the new distant sun in the sky. They read the message, and perhaps they learned something, because they finally recalled their ships and their planes."
* DeathByAdaptation: [[spoiler:Max Brailovsky]] in the film.
* DirtyCommunists
** The Russian crew of the ''Leonov'' start out acting paranoid toward the Americans, but grow more friendly toward them as the space scenes advance. However, when events on Earth reach a flashpoint, the Americans are sequestered aboard Discovery.
** The ''Alexei Leonov'' was originally supposed to be named the ''Gherman Titov'', who was the second cosmonaut and the first man to spend a day in space. Apparently, Titov "fell out of favor". In RealLife, Titov died in 2000. Leonov was still alive in 2010.
* DistaffCounterpart: SAL 9000 to HAL 9000.
* DistantFinale: "20,001" in the novel.
* DoAndroidsDream: HAL's poignant question, "Will I dream?" is never truly answered. Early in the film, another computer asks the same question, and Chandra says "Of course, all intelligent creatures dream, and nobody knows why." When HAL asks it when he knows he may be dying, Chandra decides on the honest answer: [[TearJerker "I don't know."]] This honesty is what persuades HAL to [[spoiler:make his HeroicSacrifice]]. [[spoiler: Dave is more reassuring, telling HAL that he will be wherever Dave is now.]]
* DoAnythingRobot: The Monoliths. They can teach potentially intelligent lifeforms how to hunt with weapons, transmit a radio signal when exposed to light, serve as an interdimensional transportation system, reproduce themselves, compress Jupiter's mass to initiate fusion and destroy probes attempting to land on Europa. In the novel, Curnow explicitly compares them to Swiss Army Knives.
* DuctTapeForEverything: Played for humor in the novel -- when the astronauts are connecting ''Leonov'' to ''Discovery'' in order to use the latter as a booster, they use a lot of... tape. Very ''strong'' tape, but still.
* EarthShatteringKaboom: or rather, a Jupiter Shattering Implosion.
* EiffelTowerEffect: The end of the movie shows [[BinarySuns two suns in the sky]] over various Earth landmarks: the Lincoln Memorial, St. Basil's Cathedral, the Pyramids of Giza, the [[TropeNamer Eiffel Tower]] and Tower Bridge.
* EnergyBeings: Bowman, as the Star Child.
** HAL joins him at the end of the novel, and it's implied in the film he will as well.
* EverybodyKnewAlready: Floyd has Curnow secretly install a cutoff switch in HAL's wiring trunk so he can disable him in the event that he goes rogue again. Immediately after the climactic confrontation with HAL, [[spoiler:Chandra casually tosses Floyd the device, which he had anticipated and removed months ago]].
* ExplosiveInstrumentation: Occurs aboard the ''Leonov'' when the shockwave hits it.
* {{Expositron 9000}}: HAL, reprising his role from the original film. The most outstanding example of this is HAL determining that the black spot on Jupiter is made of millions of self-replicating Monoliths, which is far more useful than he ever was in ''2001''.
* ExtremeGraphicalRepresentation: Averted on the ''Leonov'', whose displays are very practical, but of course HAL's screens show up again.
* FireForgedFriends: Max and Curnow. In the book, it goes [[HoYay much further than that]] (albeit off-stage).
* FirstContact: Check out the title.
* FreezeFrameBonus: In the very first interior shot of the ''Leonov'', the camera tilts down from a closeup of a computer monitor in the medical bay. Printed underneath the monitor is a paragraph of English text, beginning with "You may leave the lavatory if the green exit light is on over the door...." This is actually step 4 of the Zero Gravity Toilet instructions from ''2001''. Not only do you have to freeze-frame it, you need to watch the movie on Blu-Ray in order to make out the text! Additionally, the image on the monitor is captioned "KIRBUK" in Cyrillic (see MildlyMilitary below.)
* {{Friendly Playful Dolphin}}s: They swim right into Floyd's living room. [[AllThereInTheManual The novel explains]] that "The House of the Dolphins" was built in Hawaii with a tunnel connecting the pool in the living room to the ocean. The movie shows us a beach, but never the outside of the house.
* GenderFlip: Katerina Rudenko, the ''Leonov'''s chief medical officer in the novel, becomes Vladimir Rudenko in the film.
* GoOutWithASmile: Dave Bowman's mother is shown in a nursing home bed. Suddenly, she jerks up with a look of rapturous joy as a hairbrush rises and brushes her hair. She then settles back with a smile as her monitor flatlines.
* GovernmentConspiracy: The order to reveal the Monolith's existence to HAL, but not Dave or Frank, came from the National Security Council. Also see {{Retcon}}.
* TheGreatPoliticsMessUp: In the film, in 2010, the ColdWar is still around, and on the verge of getting hot, although it's remarkably right about Honduras' current troubles. This plot is completely absent in the novel; although the USSR is still around, it seems to have successfully adopted ''glasnost''[[note]]Yes, the novel predates Gorbachev, but the same general idea as ''glasnost'' anyway[[/note]] and everyone on Earth pretty much gets along.
** DoesThisRemindYouOfAnything: The Soviet Union trying to break through a US blockade of a Latin American country's seaports is a ripoff of the Cuban Missile Crisis.
* HeroicSacrifice: [[spoiler:HAL]].
* HoldMe: The ship's nutritionist, Irina Yakunina,[[note]]In the novel, the character's name was Xenia Marchenko, and Irina Yakunina was the crew member she replaced at the last minute[[/note]] goes to Floyd's quarters so that they can spend the harrowing aerobraking maneuver in each other's arms; when it's over, [[FlirtingUnderFire she kisses him on the cheek]] (though in the novel, she fell asleep).
* HumanPopsicle: The hibernation systems.
* HyperventilationBag: The equivalent to this when wearing a spacesuit is to add carbon dioxide to the air feed.
* IdiotBall: In-universe example in the film. GenreSavvy Floyd was against sending Max in a ''manned'' probe of the Monolith (It had already been proven that the Russians had unmanned probes - the one they used on Europa - and at least one more on hand), while the overconfident Russians essentially thought Floyd was superstitious. Unfortunately, Floyd was right.
* InferredHolocaust: [[invoked]] 2061 confirmed that yes, having a second sun in the sky on Earth completely fucked up many species and Earth-based astronomy.
* JustAMachine: The attitude of several ''Leonov'' crew members towards HAL (but not Chandra).
* LaserGuidedAmnesia: Chandra is able to make HAL selectively forget about his malfunction and murder of the ''Discovery'''s crew. In the novel, Bowman also erases all evidence of his presence from HAL's memory after delivering his message to Floyd. The omission of the latter from the movie creates an AdaptationInducedPlotHole: why would it be so hard to convince HAL of the importance of leaving Jupiter early if Bowman relayed the message through him?
* LivingGasbag: The indigenous lifeforms on Jupiter that Bowman observes in the novel.
* LogicBomb: The reason given for HAL's malfunction in ''2001'' is that his ObstructiveCodeOfConduct to not conceal information conflicted with his orders to hide the existence of TheMonolith from his crew.
* LookBehindYou: Used literally by Bowman/The Star Child when he reveals himself to Floyd.
* MadeInCountryX: [[invoked]] Everything about the ''Leonov'' conveys a sense that Soviet technology is ungainly but tough: the exterior is ridiculously over-engineered, the interiors are mostly dimly lit and filled with haze, and the space pods are awkward and angular compared to the spherical ''Discovery'' pods. Ironically, as an EasterEgg, the model builders included a tiny decal to the lower right of the ЛЕОНОВ marking that says "СДЕЛАНО В США" -- "Made in USA". It's barely visible on the Blu-ray in the shot where Walter and Max float out of the airlock.
** Ironically, in real life, Russia has a bad reputation with sending probes outside Earth's orbit. Most of their Mars missions, most recently Phobos-Grunt in 2012, have failed. And "outside" is meant literally; they have a diametrically great record sending probes ''inside'' Earth's orbit to Venus.
* {{Malaproper}}: Russian astronaut Max Brailovsky's attempts to use English similes are played for comic relief.
-->'''Brailovsky''': Easy as cake.
-->'''Curnow''': ''Pie.'' Easy as pie.
-->'''Brailovsky''': Piece of pie.
-->'''Curnow''': Piece of ''cake.''
* MasterComputer: Deliberately averted on the ''Leonov'', as noted below under {{Zeerust}}.
* MildlyMilitary: In the novel, the ''Leonov'''s captain, Tanya Orlova, is married to her navigator, Vasili Orlov. In the movie, the captain's name is changed to [[SdrawkcabName Kirbuk]], not only as a ShoutOut to Stanley Kubrick, but also to make the Soviet crew more serious about military discipline.
* MindScrewdriver: ''2010'' has been said to be this for ''2001''.
* MrExposition: Floyd's spoken letters back home advance the plot during spaceship shots.
* TheMonolith: Sequel to the TropeMaker.
* MotherRussiaMakesYouStrong:
-->'''Floyd:''' It has to be at least a hundred below zero.
-->'''Brailovsky:''' A typical Russian winter.
-->'''Curnow:''' I'm from California, [[YiddishAsASecondLanguage we don't know from]] a hundred below zero.
* MyGreatestFailure: Floyd was publicly blamed for the failure of the ''Discovery'' mission in ''2001'' and lost his job as a result. The ''Leonov'' mission is his chance to find personal redemption. Of course, some may think he's ''lying'' and is suffering a case of NeverMyFault.
* NamesToRunAwayFromReallyFast: The [[spoiler: Jovian sun]] is called [[{{Satan}} Lucifer]]. A very [[MeaningfulName fitting name]], as the Monolith people [[spoiler: want the Earthlings away from Europa]].
* NavalBlockade: It's never seen but there's one going on somewhere in Central America throughout the film.
* NewEden: Europa.
* NiceHat: See TragicKeepsake.
* NoBisexuals: In the book, Walter and Max briefly become a couple. In the film, they have a platonic rivalry-type relationship.
* NoNewFashionsInTheFuture: Mostly averted; the clothing in the movie is similar to real 2010 fashion. Bowman's widow wears a ''{{Flashdance}}''-style off-the-shoulder T-shirt, which came back into fashion over the past few years so it's justified here.
* NotDrawnToScale:
** On Michael Whelan's cover art for the book, the Monolith is noticeably taller than 1:4:9. (He would later avoid this for the sequel, ''2061''.) Also see BiggerOnTheInside and RebuiltSet regarding the movie's set design.
** The film says for the first time that the Monolith's proportions are 1:4:9, but as in ''2001'', it looks more like 0.5:4:9, because Kubrick felt [[RuleOfCool it looked better that way]].
* NotSoDifferent: What prompts the Soviet and American crew to eventually tell their superiors to screw themselves and continue working together.
* NukeEm: Heywood Floyd casually mentions that they've tried everything they can think of to penetrate the Monolith's exterior, including [[FrickinLaserBeams lasers]] and nuclear detonators.
* NumberTwo: The ''Leonov'''s executive officer, Yuri Svetlanov, is a character created for the movie. He's the only Russian character to have no dialogue in English.
* OffscreenTeleportation: The Star Child disappears while the camera is looking at Floyd's reaction, and ''nobody'' sees the Monolith disappear to start Jupiter's ignition process.
* OhCrap: Many instances, but the best is when HAL tells Floyd to look behind him. The expression on his face is priceless. Also, when [[spoiler: Jupiter implodes, and Floyd sees the shockwave approaching the ''Leonov''.]]
* OminousLatinChanting: Györgi Ligeti's "Lux Aeterna" returns as the Monolith's MoodMotif.
* OutrunTheFireball: When Jupiter ignites, the ''Leonov'' gets to play out this trope. Deliberately PlayedForDrama in the film; in the novel they have several days' head start and the blast does little more than peg some radiation meters.
* PetTheDog: One interpretation of why the Monolith allows Bowman to return to Earth, visit his former fiance and comfort his dying mother.
* {{Precursors}}: The aliens who made the Monolith choose this moment to make Jupiter go boom.
* ProductPlacement: TV commercials are seen for Sheraton hotels and Pan Am (using recycled footage of the spaceplane from ''2001''.) The computer Floyd uses on the beach is an Apple [=IIc=], and next to it are a Budweiser (packaged in a Capri Sun-style squeezebag) and an issue of ''Omni'' magazine (which in RealLife stopped publication in 1995.)
* PunyEarthlings: This trope is played with; the SufficientlyAdvancedAliens barely recognize humanity as individuals, and are apparently indifferent to the fate of the ''Leonov'' and ''Discovery'' until Bowman persuades them to allow him to give a warning. However, the Precursors also tell Bowman that the humans "must never know they are being manipulated", because it would "ruin the experiment".
* RaceLift: Dr. Sivasubramanian Chandrasegarampillai, Dr Chandra for short, is Indian in the novel; in the movie Dr R. Chandra is played by white actor Bob Balaban.
* RebuiltSet: See PropRecycling in ''TwoThousandOneASpaceOdyssey''. As it stands, the rebuilt ''Discovery'' fails to match the version in ''2001'' in many respects, from its size (apparently it doubled in length between films), but also the internal layout, which places walkways where ladders used to be, and also in the use of CRT screens rather than flat screens. Also see BiggerOnTheInside.
* RedemptionEqualsDeath:
** Floyd's wife asks him if he's seeking this before he leaves.
** HAL's willingness to sacrifice himself for the sake of the humans aboard the ''Leonov'' is the point where he finally achieves redemption in their eyes.
* RedHerring: For the aerobraking, a female cosmonaut comes to Floyd - a married man - scared. She clings to him through the procedure, during which the photo of his wife and child falls. After they are safe, she kisses him on the cheek. At this point any curiosity of infidelity or romance is dropped for the rest of the film. If you expected it, you've just been {{Ship Tease}}d with an extra.
* ReentryScare: The "aerobraking" technique used to enter a close Jupiter orbit is portrayed as terrifying for the Leonov's crew. It's also a case of RealLifeWritesThePlot, in that it had never been tried in real space exploration at the time when the book was written.
* {{Retcon}}: Clarke acknowledged a number of inconsistencies between ''2010'' and ''2001'' in the author's note to 2061, stating that each ''Odyssey'' book and film takes place in a similar, but slightly different, universe.
** Floyd vehemently denies knowing that HAL had been told about the Monolith, and we're clearly meant to believe him. This contradicts ''2001'', where Floyd explicitly said the existence of the Monolith was revealed only to HAL in the video that played after HAL was disconnected.
** The size and internal layout of the ''Discovery'' changes between films; see RebuiltSet and BiggerOnTheInside.
** Floyd's use of a [[CutTheJuice cutoff switch]] as a precaution contradicts the novel of ''2001'', in which HAL is said to be powered by six independent systems with a backup nuclear isotope unit specifically to prevent that sort of attack.
** The novels and films are inconsistent as to whether the Precursor technology involves FTLTravel. The novel of ''2010'' clearly states that it does, but by ''3001'' a different set of rules is in effect.
* RunningTheBlockade: US/Soviet relations take a dive when a Soviet ship tries to run the US blockade and is destroyed by missile fire.
* SceneryPorn: The chapters of the novel in which Bowman, as the Star Child, explores the ecosystems of Jupiter and Europa.
* ScrewTheRulesImDoingWhatsRight: Floyd's reason for (illegally) reboarding the ''Leonov''. That, and the fact he found out their lives were in danger.
* ShinyLookingSpaceships: Averted with Discovery, which is covered with a film of sulphur after nine years orbiting Io.
* ShoutOut:
** In the novel, the name of Sivasubramanian Chandrasegarampillai (see RaceLift) seems to have been borrowed from astrophysicist [[http://en.wikipedia.org/wiki/Subrahmanyan_Chandrasekhar Subrahmanyan Chandrasekhar.]]
** The scene in the novel where Walter and Max board the ''Discovery'' makes a ShoutOut to ''Film/{{Alien}}'': "Whatever you do, don't go chasing after the ship's cat."
** The movie's set design for the ''Leonov'' is also strongly influenced by that of the ''Nostromo'', as many other science fiction movies were: the interiors are mostly dark and claustrophobic except for the white, brightly lit medical bay and rec room.
** The reference to using "nuclear detonators" is a reference to Hyams' earlier film {{Film/Outland}}, where a missing nuclear detonator was mentioned in a daily briefing Creator/SeanConnery received.
** The Russian space pod that Max takes to the Monolith is named ГРАМПИ ''(Grampi)'' after Grumpy from ''Disney/SnowWhiteAndTheSevenDwarfs''. [[http://www.icollector.com/Syd-Mead-designed-Russian-manned-probe-from-2010_i8632922 Auction photos]] of the miniature version of the pod show that it was labeled БАШФУЛ (Bashful).[[note]]Grumpy and Bashful's names in the actual Russian translation of Disney's ''Snow White'' were Ворчун (Borchun) and Скромник (Skromnik).[[/note]]
* ShownTheirWork: Clarke is a respected astronomer who did as much homework as he could possibly have done at the time the novels were written, and it shows. The film version of ''2010'' used actual stills of Jupiter and its moons for background plates (except, of course, for the finale).
* SinisterGeometry: The Monolith makes a reappearance, of course, along with its famous 1:4:9 dimensions.
* SlidingScaleOfRobotIntelligence
* SocietyMarchesOn: It's amazing how similar the geopolitical situation in ''2010'' is to the one in 1984. Again, this applies to the movie, not the book.
* SolarCPR
* SpaceIsNoisy: Unlike the first movie, ''2010'' plays this straight.
* SpaceshipSlingshotStunt: Inverted with the aerocapture used to enter Jupiter's orbit.
* SufficientlyAdvancedAliens: Advanced enough to turn Jupiter into a star so that the newly discovered life on Europa would have a chance to survive.
* TooDumbToLive: Why exactly was it necessary to send a ''manned'' EVA pod to the Monolith (in the film) when they apparently had remote controlled probes available, especially considering what happened to Bowman?
** This is averted in the novel. They send a remote-manned pod instead.
* TouchedByVorlons: David Bowman, HAL, and by the end of ''2061'', [[spoiler: Heywood Floyd as well]].
* TragicKeepsake: [[spoiler:Max gives Walter his black beret before going on his expedition to the Monolith. After Max's death, Walter keeps wearing it for the rest of the movie, until right before he goes back into hibernation when he puts it on Irina's head.]]
* TwentyMinutesIntoTheFuture: When ''2001'' was being written, it was plausible that mankind might make it to Jupiter by then. ''2010'' was written with that continuity in mind, despite it being rather less likely. Neither happened on schedule.
* TypesetInTheFuture: Eurostile Bold Extended returns as the typeface used by both HAL's and SAL's interfaces, and all the Russian signage aboard the ''Leonov'' is set in Eurostile Bold Extended modified with Cyrillic letters. This wasn't done completely accurately: for example, an inverted V is used for the Cyrillic equivalent to L, making it look like the Greek Λ instead of the more correct Л.
* VaderBreath: During the spacewalk scenes. More like "Vader Hyperventilation."
* VaguenessIsComing: One assumes "[[spoiler: the monolith is going to transform Jupiter into a sun]]" would be too hard for folks to understand.
-->'''Almost everyone Dave Bowman talks to:''' What's going to happen?
-->'''Dave Bowman:''' [[BrokenRecord Something wonderful]].
** Justified in the book, as it reveals that the Precursers who evolved Bowman into the Star Child can't reveal "the experiment" to the human race, or it would ruin the results of that experiment.
* VirtualGhost: Being made of energy, Bowman is capable of directly interfacing with computer systems -- he uses this ability to talk to HAL and to several people on Earth, including his (now remarried) wife and his mother.
* WhamLine:
-->'''Curnow:''' It's ''shrinking''! ''IT'S SHRINKING!''
* WhatMeasureIsANonHuman: Played for enormous tension in the sequence where Dr. Chandra is asked to convince HAL to use ''Discovery'' as a booster to allow the ''Leonov'' to escape. Floyd and Curnow want to trick HAL into compliance and disconnect him if he resists, while Chandra insists on telling him the whole truth.
** The funny part is that [[spoiler: Chandra ''knew'' Floyd was up to something, and he would not have been able to disconnect HAL with the failsafe device. Floyd's huge grin at Chandra reveals he was happy to be wrong.]]
* {{Zeerust}}: The second manned mission to Jupiter is launched in time to make it by 2010. The first one had an AI, but in this one the Soviets use [[OurGraphicsWillSuckInTheFuture CRTs]] while the Americans have flat-screen displays. [[JustifiedTrope Justified]] in the novel by the fact that they intentionally used small autonomous computer systems to run the ship to avoid the same catastrophe that befell ''Discovery''.
** It's plausible that if Russia had remained Communist, they could still be using [=CRTs=] in 2010. It doesn't explain why all the flatscreens on ''Discovery'' turned into [=CRTs=], though.
** The Apple [=IIc=]'s design still looks sort of futuristic, if you ignore its thickness and its tiny screen connected with a ribbon cable.
