->''"I created the ''Event Horizon'' to reach the stars, but she's gone [[GoneHorriblyRight much, much farther than that]]."''
-->-- '''Dr. Weir'''

A 1997 SciFiHorror movie by Creator/PaulWSAnderson where astronauts investigate an experimental ship (the eponymous ''Event Horizon'') that disappeared under mysterious circumstances.

[[MindScrew Okay, a little more explaining...]]

[[TwentyMinutesIntoTheFuture In the year 2047]], a signal from the starship ''Event Horizon'' is picked up on Earth. The ship had disappeared without a trace beyond Neptune seven years earlier. The ship has reappeared in a decaying orbit around the planet Neptune, and the rescue ship ''Lewis and Clark'' is dispatched to investigate. The ship's crew is commanded by Capt. Miller (Creator/LaurenceFishburne) and carries the ''Event Horizon''[='=]s designer, Dr. William Weir (Creator/SamNeill).

No definitive trace of human life is found; inconclusive sensor readings lead the ''Lewis and Clark''[='=]s crew to enter the ''Event Horizon'' to search for survivors. Things start to go very wrong very quickly, it appears that someone--or some''thing''--is toying with them. Strange noises echo throughout the ship, sensors indicate the presence of life forms even through the vessel is clearly deserted, and what few records the ''Lewis and Clark's'' team recover hint that [[GoneHorriblyWrong something went terribly wrong]]... and that's just the beginning. Before long, the question is no longer what became of the ''Event Horizon,'' but what has the ''Event Horizon'' ''become?''

''Event Horizon'' is a CosmicHorrorStory, basically [[Creator/HPLovecraft Lovecraft]] [-[[RecycledINSPACE IN SPACE!]]-] Or as some like to call it, a ''very'' disturbing prequel to the ''TabletopGame/{{Warhammer 40000}}'' series.

Not to be confused with MoralEventHorizon, or DespairEventHorizon. Or, for that matter, the term for the region around a black hole from which light can no longer escape. For the game that was ''heavily'' inspired by the film, see ''Franchise/DeadSpace''.

----
!! ''Event Horizon'' contains examples of:

* AbsentAliens: Though it's implied there is ''something'' out there, no non-human life forms are ever seen. [[spoiler:Unless you count the possessed-by-evil ship itself.]]
* AlliterativeName: Doctor William Weir.
* AntagonistTitle: [[spoiler:The ship becomes alive and demonic after passing through Hell]].
* ApocalypticLog: "''Liberate tutemet ex inferis...''" The final, decoded version of this log entry, which places those words into context, is one of the most infamous examples of this trope in cinema; it's even been referenced in ''WesternAnimation/SouthPark''.
* ArtisticLicenseAstronomy: Strangely averted, given the liberties taken with physics below: Neptune looks like Neptune should look; we see an accurate depiction of its moon Triton in the foreground as the ''Lewis and Clark'' enters the system; its small moon Nereid is briefly glimpsed, and Miller mentions that they are "three billion clicks from the nearest outpost," which happens to be the orbit of Saturn (perhaps a colony on Titan?).
* ArtisticLicensePhysics:
** It's noted in the film that the FTL Drive the ''Event Horizon'' supposedly has '''can't''' work because of the Law of Relativity stating that FTL travel is impossible. William Weir, as he puts it, had to work around it, which is where Folding Space comes into play and the cause of everything that happens in the movie.
--->"You break all the laws of physics, and you seriously think there wouldn't be a price?"
** The movie never quite works out which pseudophysics handwave it intends to use for the ship's FTL capability; the description given by Weir suggests the ship works by warp drive; his demonstrated metaphor works more like a wormhole; however, the events that actually transpire suggest it was some kind of hyperdrive.
* BathSuicide: Weir's wife, Claire, which constantly comes to haunt him.
* BattleAmongstTheFlames: The final confrontation between Miller and the demon-possessed Weir.
* BigBad: The ''Event Horizon'' itself.
* BigNo: Delivered by Weir when Miller activates the explosives.
* BigOMG: Miller after he sees Weir's self-inflicted EyeScream.
* {{Bizarrchitecture}}: The ''Event Horizon'' itself. The hallway leading to the engine room is a giant rotating tube lined with spikes. The engine room itself is lined with yet more SpikesOfDoom, and the engine itself is literally beautiful. It's ''cool'', but the actual purpose of the design is {{Hand Wave}}d away as "[[{{Technobabble}} reducing the effects of the gravitational field]]." In reality, the ship's exterior itself was designed by scanning in images of Notre Dame Cathedral and mix-and-matching the various elements. Even the structural scaffolding along the neck was based on the stained-glass windows of the Cathedral.
* BlackDudeDiesFirst: Averted. Cooper, who in any other movie would be [[UncleTomfoolery prime fodder]] for this trope, is one of the few to survive the entire film.
* BodyHorror: Gratuitous EyeScream happens. Also, a frozen body shatters to pieces on the floor when gravity comes back.
* CameBackWrong: The whole ship. Weir, too.
* CanisLatinicus: Notably averted. The phrase in question, while often misheard as "Liberate tutame ex inferis" (which makes no sense), is actually "Liberate tutemet ex inferis", which is good Latin and means what they say it does ("Save yourselves from hell"). [[labelnote:For those interested in the Latin itself]] "Liberate" is the plural command form of "free", and "ex inferis" means "from hell". Those are easy enough. "Tutemet" is a bit tricky though--it ''is'' a real Latin word, and it was used by classical Roman writers, but it is kind of rare: "tu" means "you", and "te" means "yourself" (reflexive pronoun). "Tute" is a word on its own, meaning "you yourself; yourself". The suffix "-met" is an intensifier that adds the meaning "himself, itself" to words it is attached to. It is perfectly allowed within the rules of Latin to stack a couple of intensifiers together, thus "tu-te-met" = "you yourself, yourself" (very intensive meaning). It just looks a little odd to the non-native speaker when you dissect the literal meaning of the word parts: the Romans themselves certainly used it to mean "yourself". More commonly "te ipsum" would be used, "te" = "you", and "ipsum" is actually the commonly used pronoun for "yourself". Of course, if they used the much more common and simple "te ipsum", the entire plot point would be lost that the doctor originally misheard the word "tutemet" (he heard "me", which happens to be the same in English and Latin).[[/labelnote]]
* CatScare: When first exploring the ''Event Horizon'', Miller is spooked by what looks like a hand grabbing his face. It's just a loose glove from a space suit floating in the gravity free environment.
-->'''Cooper:''' ''(amused)'' Cap's got a case of the heebie jeebies.
* ChekhovsGun: The explosive ship-cutting charges.
* ClusterFBomb: Cooper, in keeping with his status as resident UncleTomfoolery.
* ConvenientlyInterruptedDocument: At the beginning of the film, the ship receives part of a signal from the title vessel containing a message in Latin. As the signal is partly corrupted, they initially take the message to be "''Libera te me''"--"save me." Upon acquiring the full signal and inspecting it closer, they find that the message is actually "''Liberate tutemet ex inferis''"--"Save yourselves from Hell."
* ConvenientlyPreciseTranslation: Subverted. The distress signal sent by the titular starship contains the Latin phrase ''liberate me'' ("save me"). It was later realized that the message was very different.
* CoveredWithScars: When the ship brings Weir back for the final showdown, he is bald, naked, and covered in freaky scars. It did give him his eyes back, strangely enough.
* DecoyProtagonist: The opening scenes might incline you to believe that Weir is the protagonist, [[spoiler:but by the end, it's clearly Miller.]]
* DespairEventHorizon: Weir's leads to his crossing the MoralEventHorizon. (Sense a pattern?)
* DistressCall: The ''Event Horizon'' sending one after having disappeared a long time ago is what kicks off the story.
* DoorClosesEnding: It ends with the door closing to the sleep chamber deck as Starck screams uncontrollably from the stasis nightmare she's had as the rescue crew try fruitlessly to calm her.
* DoubleEntendre: Cooper, in a ShirtlessScene, offers Starck a cup of coffee.
-->'''Cooper:''' Want something hot and black inside you?\\
''Starck flips him off''[[note]]Generally meaning "Fuck you"[[/note]]\\
'''Cooper:''' Is that an offer?\\
'''Starck:''' It is not.\\
'''Cooper:''' Well, how 'bout some coffee, then?
* DramaticDrop: Peters does this upon seeing the restored ApocalypticLog.
* DramaticThunder: Lightning illuminates the ship interiors occasionally, justified in that the ship is in a decaying orbit around Neptune which has storms with wind speeds up to 2000 km/h. The ship is already in the upper thermosphere and continues falling deeper into the atmosphere over the course of the film. [[ParanoiaFuel Or maybe it's just the ship]] [[MindScrew fucking with their brains?]]
* DreamingOfThingsToCome: The first image of the film is Weir's nightmarish vision of the ship.
* DrivenToMadness: Weir, after the ship continually shows him horrific visions of his wife and makes him relive his wife's suicide.
* DrivenToSuicide:
** Weir's wife in his backstory.
** Justin tries to blow himself out an airlock after being sent through the singularity. However, since he snapped out of it halfway through, it's equally likely that [[PsychicAssistedSuicide the ship made him do it]] then [[KickTheDog left at just the right moment]] for him to [[OhCrap realize he's about to die horribly]].
* DyingMomentOfAwesome: If he wasn't transported to hell, and perished in the explosion Miller went out with a huge bang.
* TheEeyore: D.J. {{Lampshaded}} by Miller, who refers to him as a "gloomy Gus."
* EldritchAbomination: It's unclear just what happened to the ship, but it's hinted pretty heavily that it brought one of these back with it, or became one itself. Whatever happened, the sensor suite on the ''Lewis and Clark'' says that the [[GeniusLoci ENTIRE SHIP IS ALIVE]].
* EldritchLocation: This is putting what's on the other side ''very'' lightly. The ship itself is this, too. If not both being a single and/or networked, ''very'' bizarre GeniusLoci. Who isn't very nice.
* EldritchStarship: The ''Event Horizon'' was an excellent example of one even ''before'' it was [[spoiler:warped into a tortured consciousness by exposure to a [[HyperspaceIsAScaryPlace hellish extradimensional realm]].]] Note the interior design of the ship, with its [[{{Bizarrchitecture}} odd cybergothic architecture, including its extremely strange "central core" and the "meat grinder corridor" leading to it, as well as the numerous spikes and other elements of its rather terrifying aesthetic]] (some of which, like the "meat grinder corridor," are handwaved as being essential to the ship's operation). It's definitely one of the weirdest human-designed ships on this list, even before being [[spoiler: possessed by extradimensional evil]]. It's also one of the closest examples on this list to an StandardHumanSpaceship, despite being simultaneously ''this'' trope.
* EpicTrackingShot: The vertigo-and-motion-sickness-inducing pull-out from Weir opening his shutters, revealing him to be on a sprawling space station in orbit above Earth.
* EvilGloating:
-->'''Weir:''' Do you see? DO YOU SEE? '''DO YOU SEE?'''\\
'''Miller:''' [[ThwartedCoupDeGrace Yes. I see.]]
* EvilIsHammy: For much of the film, Weir is rather quiet and self-effacing. After [[spoiler: he's taken by the ship,]] he quickly becomes as [[LargeHam theatrically evil]] as you'd expect.
* {{Expy}}: Universal Orlando's annual Halloween Horror Nights event had the haunted house "Interstellar Terror" in 2008, which the Art & Development team proudly admitted was directly inspired by ''Event Horizon'': the first interstellar star ship disappears, then reappears several years later orbiting the moon. You go aboard and find that an alien artifact the crew found has driven them into homicidal insanity.
* ExtyYearsFromNow: Produced in 1997, and set in 2047.
* EyeScream: This movie might hold some kind of record for most injured eyes/sockets in a major Hollywood movie. In fact, the very ''first'' person we see in this film is missing eyes! This is barely two minutes in, mind you.
** One scene in particular [[UpToEleven takes the cake]]: [[spoiler:In the video of the previous crew, aptly named [[ApocalypticLog "the Blood Orgy"]], you see the captain of said crew, Kilpack, holding his own eyes. However, if you [[SchmuckBait slow it down]], you notice that he appears to still have eyes in his sockets, so he must be holding someone else's eyes, right? Nope. Look closer and you'll notice that the skin around the eyes in his face doesn't match the rest of him, and that the eyes seem to be crooked, and then the reality of what you're looking at kicks in.]]
* EyelessFace: Due to the above.
--> "Where we're going, we won't need eyes to see."
* FaceHeelTurn: [[spoiler:Weir. Played with, as it seems he may have been possessed by the ship itself.]]
* FailsafeFailure: The airlocks on the ''Event Horizon'' are designed in such a way that a depressurization sequence cannot be canceled from either side of the airlock once it's been activated. While it is a reasonable precaution not to allow both the inner and outer doors to be open at the same time, there is no excuse for not having an abort command when it takes half a minute to actually finish depressurizing the airlock. Then again, what isn't affected by the Eldritch force inhabiting the ''Event Horizon''?
* FanDisservice: Weir's hallucination with his dead and half-naked wife.
* FasterThanLightTravel: ''Event Horizon''[='=]s purpose. Didn't go so well.
* FateWorseThanDeath: What awaits anyone entering hyperspace.
* FullFrontalAssault: [[spoiler:Weir.]]
* GenreShift: Starts out as a near-future hard SF space exploration movie, but doesn't really stay that way.
* GhostShip: The ''Event Horizon''.
* GoMadFromTheRevelation: Apparently even a glimpse of hyperspace is too much for most people's minds to handle.
* GoneHorriblyWrong: The film's basic premise is an attempt at [[FasterThanLightTravel FTL]] that Goes Horribly Wrong.
* {{Gorn}}: While the film itself is bloody (the original cut was so unnerving that 30 minutes were cut before release), the ApocalypticLog falls straight into this.
* HumanoidAbomination: [[spoiler: Implied with Weir post resurrection. He gains a VoiceOfTheLegion in some parts and is covered with ritualistic scars, hinting that it's the ship using his form to confront Miller.]]
* HeadDesk: Dramatic example; in the aftermath of [[spoiler:Smith's death]], Miller does a subdued version of this against the nearest wall.
* {{Hellgate}}: To all intents and purposes, this is what the engine core with it's DarkIsEvil take on a spiked Stargate is alongside its stated objective of being an FTL Drive. The rest of the ship? Who knows: the atrium with welcome mat, perhaps? Flypaper? It's hard to say what.
* HeroicSacrifice: [[spoiler: Miller lets himself get blown up just as the ship is about to enter hyperspace to save the rest of the crew. Granted he didn't have time to escape the ship and death is a far better fate than what was waiting for him in the other dimension.]]
** FamousLastWords:
--->'''[[spoiler: Miller]]:''' Yes. ''I see''.
* HyperspaceIsAScaryPlace: things [[GoneHorriblyWrong went horribly wrong]] due to the ship "[[OurWormholesAreDifferent folding space]]"... [[ToHellAndBack and returning]]. The "hyperspace" the ship goes into is strongly implied to be either Hell itself, or something far, far worse than what you're probably imagining right now. Weir describes it as a dimension of "pure chaos"--chaos as in a lack of normal natural order.
* ImAHumanitarian: Yet another facet of the final log entry.
* ImColdSoCold: Spoken by an apparition of Weir's wife early in the film. Made all the more chilling when we realize how she died.
* ImprovisedWeapon: The rivet guns (meant for repairing hull damage) used in the climax.
* InertialDampening: The rescue ship ''Lewis and Clark'' has an ion drive that produces 30 gees of acceleration, so the crew spends the trip sealed into fluid-filled pods to avoid becoming wall-gazpacho. This might also explain the interior of the ''Event Horizon'' when it returned.
-->'''D.J.''': When the ion drive fires, you'll be taking about 30 [=Gs=]. Without a tank, the force would liquefy your skeleton.
-->'''Weir''': I've seen the effect on mice.
* InSpaceEveryoneCanSeeYourFace: Averted.
* ItCanThink: And she wants a new crew.
* ItsTheOnlyWayToBeSure: Upon seeing just what really happened to the ''Event Horizon''[='=]s original crew, Miller decides that the best thing for everyone is to fire missiles at it until it ceases to be a ship.
* KnowWhenToFoldEm: (upon seeing the restored Apocalyptic Log) ''"We're leaving."''
* LastNoteNightmare: The Paramount logo starts out normally, then the soundtrack wails, as the logo darkens and lifts away, and then the score begins with a threatening string section.
* LaymansTerms: Weir tries to explain... and {{Technobabble}} comes instead of simple terms.
-->'''Miller:''' ''Layman's'' terms.\\
'''Cooper:''' Fuck layman's terms, do you speak ''English?''
* LittlestCancerPatient: Peters has a son with some unspecified condition affecting his legs. So naturally, the ship uses this against her.
* LoveMakesYouEvil: Dr. Weir's guilt over his wife's suicide is exploited by the ship to its full extent.
* MaybeMagicMaybeMundane:
** Weir's first few nightmares would seem to be mundane since he is not yet on the ship, but they also appear to be prophetic, suggesting perhaps a greater range of influence for the ship than we might first suspect. Or his grief and guilt are so strong, it's the first natural thing for the ship to latch on to and exploit.
** The ship also seems to exploit past grief and guilt: Miller's guilt over his crewman's death, Peters's guilt over her son, Weir's guilt over his wife.
* MeaningfulName: The ''Event Horizon'' is a ship that creates a black hole to travel through space-time; an event horizon is the point in the gravitational pull of a black hole beyond which nothing, not even light, can escape.
* MeatMoss: The bridge of the ''Horizon'' seems to have some stretched across the walls. If you look closely, you can see ''screaming faces'' in it.
* MindRape: [[spoiler: Weir projecting nightmarish images to Miller of his crew in "hell."]]
* MonsterFromBeyondTheVeil:
** The ''Event Horizon'' herself, on her return from hyperspace.
** The ship employs several, though most are arguably either hallucinations or phantoms reconstructed by the ship from their own minds.
* MyGreatestFailure: Miller leaving an ensign to burn in a spaceship fire. It's the core of his NoOneGetsLeftBehind attitude.
* NightmareSequence: At the end, Starck has a nightmare and wakes up screaming in Cooper's arms as he and the rescue team try to calm her down.
* NoOneCouldSurviveThat: Uttered by Starck when Weir is blown through the breached window into space; Miller doubts it. They still arm themselves, just to be sure.
* NoOneGetsLeftBehind: Miller. His {{Backstory}} explains why.
* NoOSHACompliance: A room that has a pit leading into the gravity drive chamber, completely lacking any guard rails to stop anyone from falling on. Some of the horrific failures could be blamed on the ship being possessed, but the entity is never shown to have outright reconfigured the ship.
* NotThatKindOfDoctor: Possibly subverted. Dr. Weir is a doctor of theoretical physics, but shows an amazing grasp of surgery and anatomy later in the film. This is most likely due to the [[PowersViaPossession Event Horizon possessing him]] as the 'surgery' was preformed by an eyeless Weir and around/after this time he was also able to [[NeckLift neck lift]] and throw people across a room with unnatural ease for someone with his build.
* OhCrap:
** Smith gets one when [[spoiler:he finds the misplaced explosive charge, seconds away from going off]]. He doesn't ''say'' anything, but his humiliated, terrified cringe speaks for itself.
** Cooper also has a few of them.
--->'''Cooper:''' Why's this shit always gotta happen to ''me''?!
--->'''Cooper:''' ''(when the ship fills with blood)''... Oh, fuck me.
** D.J. has obviously just had an OhCrap moment when he comes to speak to Miller about the message in Latin; he's sweaty and nervous in a way that is [[TheStoic extremely out of character for him]].
** Justin, after being released from his trance and realizing he has just trapped himself on the wrong side of a ''depressurizing airlock '''without a pressure suit'''''.
** D.J. has another one when he turns around and ends up facing now-eyeless, possessed Dr. Weir.
* OutrunTheFireball: Miller, but then this is a hallucination, and it's not even normal fire in that context.
* PapaWolf: Miller is very protective of his crew. See PunctuatedPounding below.
* PhlebotinumAnalogy: The "folding space."
* PrecisionFStrike:
-->'''Miller:''' I have no intention of leaving her, Doctor. I will take the ''Lewis and Clark'' to a safe distance, and then I will launch TAC missiles at the ''Event Horizon'' until I'm satisfied she's vaporized. '''''FUCK this ship.'''''
* PsychologicalTormentZone: The ''Event Horizon'' acts as this in general. She/it/whatever makes your standard, everyday {{Troll}} look positively tame.
* PunctuatedPounding: "YOU! WON'T! TAKE! MY! CREW!"
* RainOfBlood: Of the 'actually raining blood' variety, near the end of the movie.
* ReasonableAuthorityFigure: Captain Miller. His reaction to seeing [[NightmareFuel what happened to the old crew]]? [[KnowWhenToFoldThem Aborting the mission, exiting post-haste and blowing the ship into its component particles.]]
* RecycledINSPACE: ''Film/{{Solaris|1972}}'' as Horror. Also, according to [[http://www.imdb.com/title/tt0119081/trivia IMDb]], it was pitched as "''Film/TheShining'' in space."
* RedemptionEqualsDeath: Miller is haunted by the memory of the crewman he left behind to save himself. In the end, he saves what is left of his crew by sacrificing himself.
* RedEyesTakeWarning: The hallucination of Weir's wife, Claire, that keeps popping up. Notable in that her eyes are ''entirely'' red. The reason for that being that, like so, so many other people, her eyes are gouged out in the hallucination.
* RuleOfCool: The Captain of the ''Event Horizon'' firmly believed AltumVidetur. After bidding farewell in English, he gave his sendoff in Latin; "Ave Atque Vale--Hail and farewell." The reason he spoke Latin in "the tape" is because, well, AltumVidetur.
* SanitySlippage: When you touch "the beyond."
* SayMyName: Weir screams Miller's name repeatedly, just before [[spoiler: he gets sucked out the breached window]].
* SchmuckBait:
** Even without the warning being fully translated, the demonic vocal tone and the agonized and clearly tormented screaming and wailing in the background should have been, by themselves, enough of a collective warning for all to stay away from the ''Event Horizon''.
** The gateway-goop of the gravity drive in the center of a [[{{Bizarrchitecture}} massive and scary room filled with massive and scary spikes, the entrance to which is a corridor that is compared to a meat grinder]].
* SelfDestructiveCharge: Leading to HeroicSacrifice.
* SendInTheSearchTeam: The crew of the ''Lewis and Clark'' are sent to find survivors and salvage what they can from the ''Event Horizon.''
* SequelHook: What happens when the drive section of the ''Event Horizon'' returns?
* ShooOutTheClowns: Possibly the darkest example in cinema. [[spoiler:When Weir starts his rampage, his first act is to blow up the ''Lewis and Clark''. Cooper survives on a piece of wreckage, but is blown clear. He blows his air supply to try to return, but we don't see him again until much later.]]
* ShoutOut: The Burning Man, to ''Literature/TheStarsMyDestination''. The working title of the movie during filming was even ''The Stars My Destination''.
* ShowingOffThePerilousPowerSource: In the Engine Room of Doom.
* SlasherSmile: Possibly the most disturbing part of the ApocalypticLog (and that says ''a lot'') is Kilpack flashing one in front of the camera while uttering ''"Liberate tutemet ex inferis."''
* SmartPeopleKnowLatin: The use of Latin by the captain in the ApocalypticLog seems to be there partly to suggest what an educated guy he is.
* SoundtrackDissonance: The end credits features the techno song "[[http://www.youtube.com/watch?v=fc07IVuw61o Funky Shit]]."
* SpaceIsCold: Averted; since the ship is in the upper atmosphere of Neptune, the cold is only natural. It is also definitely pressurized when they first arrive; life support's just been offline for quite some time, so the ship has naturally gotten extremely cold.
* SpikesOfDoom: In the DVD commentary, the director states that the spikes in the gravitational drive room were originally intended to engage with the core, but this wasn't possible due to budget constraints. They were left in due to the RuleOfScary.
%%* StaggeredZoom
* TheStoic: Miller, with a touch of JerkAss thrown in.
* SuicideMission: Hinted at by Miller, who notes rescue missions as far out as Neptune usually end in TotalPartyKill.
* TakeMeInstead: Captain Miller offers himself in exchange for his crew. The response is "No. There is no escape. The gateway is open, and you're all coming with me!"
* TakeMyHand: When Miller saves a crewmember from being sucked out the ship's broken window into space.
* TakeOurWordForIt: Averted. First we see people watching the horrifying slaughter of the original ''Event Horizon'' crew... then a significant chunk of the video [[spoiler:(the part where Captain Kilpack has torn his own eyes out and is holding them up to the camera)]] is shown to the audience.
--> '''Miller''': [[KnowWhenToFoldEm We're leaving.]]
* TechnologyMarchesOn: Averted. Though the prop for the ship's log is a CD, in-universe it could be the [[UsefulNotes/BluRay cheap circular medium]] of 2047. Also, the visual displays are flat and feature touch-screens, some of which are wireless and portable. The gadgets used by the crew bear a striking resemblance to the advent of [=IPads=] and tablet technology that couldn't possibly have been foreseen at the time, especially considering that [[Film/MinorityReport movies made years later]] show characters doing things like reading incredibly technologically-advanced newspapers, rather than simply reading the news on their smartphone.
* TeleporterAccident: The ''Event Horizon'' was supposed to travel to Alpha Centauri. Instead it wound up in Hell for about a decade and came back alive.
* ThereIsNoKillLikeOverkill: [[DefiedTrope Defied.]] This is what Captain Miller ''wants'' to do, but Weir and the ''Event Horizon'' make sure he never gets the chance.
* ThrownOutTheAirlock: The blood vessels in Justin's [[EyeScream eyes explosively decompress]], as do his surface blood vessels, which is more or less correct behavior in vacuum (or Neptune's atmosphere's near-vacuum at that altitude).
* ToHellAndBack: Hell is just a word, however. The reality is ''much, much'' worse.
* TooDumbToLive: Justin. The kid just stands there going "durr" while the main drive warms up and soon afterwards sticks his hand in mystery goo. The results pretty much follow the procedure you'd expect them to. Given the ''Event Horizon'' can manipulate people, however, this might not be ''entirely'' his fault.
* TouchedByVorlons: [[spoiler:Dr. Weir.]]
* UncleTomfoolery: Cooper, all the damn time. "HERE I COME, MOTHERFUCKEERRRS!" Used for PluckyComicRelief and a foil to Captain Miller's dour seriousness.
* UltimateEvil: The dimension that the ''Event Horizon'' crossed into, which has been equated to Hell itself (both in universe and in real life). Just a few minutes within was enough to drive one character to the brink of suicide, while the ''Event Horizon'''s original crew went insane and slaughtered one another during the initial voyage.
* VertigoEffect: Used when Weir is trying to fix an electrical fault in the gravity drive and hears someone else crawling around nearby.
* VoiceOfTheLegion: It's only for one line, but Dr. Weir's infamous "DO YOU SEE" uses this as an effect.
* TheWatson: The space marines need to get Weir to explain, in simple words, how the ship's FTL drive works, which of course allows him to explain it to the audience as well.
* WhamLine:
--> '''D.J.''': ...I thought it said ''Libera te me''. "Save me." But it's not "''me''". It's "''Liberate'' '''''tutemet'''''." "Save yourselves." And it gets worse... I think... that says "''ex inferis''". "Save yourselves... from Hell."
* WhatDidYouExpectWhenYouNamedIt: Naming your ship after the point in which escape from a black hole is theoretically impossible isn't the greatest of omens.
* WhatExactlyIsHisJob: Other characters joke about this with Cooper. He states that he's the ship's "Rescue Technician."
* WhenThingsSpinScienceHappens: Used and averted. On one hand, the gravitational drive is always spinning due to [[{{Technobabble}} magnets]]. Averted in that the real science happens when it stops.
* WithGreatPowerComesGreatInsanity: Poor Weir; the ''Event Horizon'' is working on him before they even arrive.
