''Doom'' is a 2005 SciFiHorror film, loosely based on the ''Franchise/{{Doom}}'' series of video games created by IdSoftware. It was directed by Andrzej Bartkowiak and stars Creator/KarlUrban and Wrestling/DwayneJohnson as SpaceMarines who have to figure out what went wrong with an outpost on Mars.

After option deals with Universal Pictures and Columbia Pictures expired, id Software signed a deal with Warner Bros. with the stipulation that the movie will be greenlit within 12 months. Warner Bros. lost the rights, which were subsequently given back to Universal Pictures who started production in 2004.

In an interview with executive producer John Wells, he stated that a second film would be put into production if the first was a success at the box office. Ticket sales for the opening weekend totaled more than US$15.3 million, but promptly dropped to $4.2 million in its second weekend and the story for a sequel was never written.

!! This movie contains examples of

* AbsurdlySpaciousSewer: The Olduvai complex has one of these. For [[RuleOfScary some]] reason.
* AllMenArePerverts: Portman and the Kid goggle at a woman undressing for a few long moments. [[spoiler: It turns out that she's mutating into a demon.]]
* AnkleDrag: [[spoiler: Duke]] is killed by an especially gruesome version of this. An Imp grabs his ankles and pulls him ''through'' the floor grate he was unlucky enough to be standing on, to quote the script, "as though through a strainer."
* AxeCrazy: Some of the infected, such as Dr Olsen and [[spoiler: Sarge]], often become this as their infection starts to take hold and they start to turn.
* AnArmAndALeg: A scientist in the opening gets her arm lopped off by a closing door. It becomes a plot point later on.
* ArmorPiercingQuestion:
-->'''Reaper:''' What was in the files? What were you sent to protect?
-->'''Sam:''' The research data!
-->'''Reaper:''' Research into ''what''?
* ArtisticLicenseGunSafety: The Marines check their personal cameras, by circling up...and pointing the muzzles of their rifles at their teammates. [Adding insult to injury this is with weapons that they have already knowingly loaded for combat.]
%%* AssholeVictim: [[spoiler:Portman]] and Dr. Carmack.
* AsTheGoodBookSays: Goat quotes ''1 Peter 5:8'' (KJV) while the squad is in the sewer.
-->'''Goat:''' Be sober. Be vigilant. For your adversary the devil walketh about, seeking whom he may devour.
* AtrociousAlias:
** Invoked by Samantha when she asks about her brother's nickname 'Reaper'.
** The Kid invokes this when he is assigned his nickname.
* BaldBlackLeaderGuy: Sarge.
* BetterToDieThanBeKilled: [[spoiler:Goat]] is DrivenToSuicide by slamming his head into the glass over and over again before he can fully become a monster.
* {{BFG}}: Sarge liberates one from the armory. It's called "Bio Force Gun" there, but Sarge states its TRUE full name when acquiring it ("Big... Fucking... Gun...").
* BigBrotherInstinct: John will fight the hordes of hell to save his sister.
* BigShutUp: "Portman, you need to SHUT THE FUCK UP!"
* BlackAndWhiteMorality: Chromosome 24 seems to have this. It [[spoiler: turns good people into supermen and bad people into monsters]]. Furthermore, the mutants choose who to infect based on this, preferring to infect [[spoiler: bad people, to grow their numbers and not give their prey an advantage]].
* BlackDudeDiesFirst: Averted. All three black characters make it [[spoiler: a decent chunk of the way through the movie.]]
* BodyHorror: Rife throughout the movie.
** [[spoiler: Although one notable point was the video depicting [[PatientZero Curtis Stahl's]] mutation into a hulking monster. The transformation starting in the hand and wrist where he was injected and slowly progressing up his arm...]]
* BorrowedBiometricBypass: The Sarge uses the severed hand of the woman from the intro, to access the [=BFG=].
* BrickJoke: When Duke first encounters a nanowall, his response is: "No, I don't do nanowalls," but no explanation is given. A while later, when [[spoiler: Carmack, who has mutated into an imp,]] attacks and gets caught in the nanowall Duke tells Sam: "''That's'' why I don't do nanowalls."
* CatScare: Several. Throughout the movie, random animals appear for no reason other than to spook the Marines, and then quickly vanish [[WhatHappenedToTheMouse with no explanation]].
* ChainsawGood: During the FPS sequence, [[spoiler:Reaper]] is attacked by a monster wielding a chainsaw. Later, he has to use one against [[spoiler:monsterized Pinky]].
%%* ChivalrousPervert: Duke.
* CoversAlwaysLie: At no point in the film is an FN P90 used. The movie also has nothing to do with Hell, despite the poster's tagline. Although they do ''try'' to make some connection, mostly with the following line:
-->'''Reaper:''' Christ, don't you get it? It's this place, it's hell, it always was.
* CreativeClosingCredits: The first part of the end credits is an another FPS sequence, with someone gunning down names instead of monsters. Fittingly, when the actors' names start showing, only the names of those whose characters died during the movie get shot.
* DarknessEqualsDeath: The first squad member death occurs in the sewer, after his flashlight fails.
* TheDarknessGazesBack: When one of the soldiers sees a pair of eyes in the darkness. He calls out, thinking it's one of the scientists he's looking for... only to see all the other eyes of the mutated monster opening just before it springs.
* DecoyProtagonist: [[spoiler:Sarge. The actual Doomguy is Reaper. Sarge even thinks he's still the hero, as prior to being dragged off to certain death, screams "I'm not supposed to die!" Turns into a GeniusBonus when you remember that video game Doomguy was a grunt who killed his Sergeant.]]
* DisproportionateRetribution: When [[ItMakesSenseInContext Pinky asks what Portman is doing in the bathroom]], he calls him a "fucking gimp''. Later when [[spoiler: he's attacked by one of the monsters]], Pinky doesn't give out his position to his teammates so they can save him.
* DirtyCoward:
** Portman, though he has several moments of LovableCoward, too.
** Pinky, given that he apparently [[spoiler:flees through the Ark rather than destroy it and the hell knight attempting to get through it with a grenade, as he was ordered]].
* DistressCall: Dr. Carmack sends one in the opening scene, though it wasn't so much a distress call as it was a command to initiate the containment procedures.
* DoingInTheWizard: An element of the adaptation being changing the antagonists from demons from hell in the original game, to mutants created through splicing some LEGOGenetics learned from [[LostTechnology alien ruins]].
* DoomedByCanon: Fans of the game will have known what will happen to Pinky the moment they heard his nickname.
* DullSurprise: Done deliberately when itís discovered [[spoiler: Mac]] got his head torn off.
-->'''Sarge:''' Aw, shit.
* DyingMomentOfAwesome: [[spoiler:Destroyer]] doesn't survive his encounter with the Hell Knight, but he sure puts up one hell of a fight before succumbing.
* EleventhHourSuperpower: [[spoiler:Sam injects Reaper with C24 to save him from bleeding to death after he is struck by a ricocheting bullet near the end of the film, granting him superhuman abilities for the final fights]].
* EmpoweredBadassNormal: [[spoiler: Reaper becomes one after the injection of C24 Sam gives him "judges" him to be worthy of the SuperSerum effects. Sarge also gets infected and despite it turning him AxCrazy and slowly turning him into a monster, the mutation grants him enough strength to fight evenly with Reaper.]]
* EpicFail: [[spoiler: Mac]] spends the first half of the movie guarding the Ark. When he is finally called into the facility, his head is ripped off pretty much instantly. Not once did he fire his weapon, nor did he likely even see a demon.
* EpicFlail: During his fight in the prison pit, Destroyer uses a ''computer monitor'' in this manner.
* FauxAffablyEvil: [[spoiler: Sarge becomes this at the end of the film, when the virus begins pushing him into AxCrazy violence, and even acting friendly and chatty with Reaper despite literally ''twitching'' with bloodlust.]]
* FirstPersonPerspective: Perhaps the best known scene in the movie involves [[spoiler:Reaper]] slaughtering waves of zombies and demons in the games' first person perspective.
* HalfTheManHeUsedToBe: Pinky, thanks to a glitch in teleportation, lost the lower half of his body. Fortunately, thanks to the advanced technology, he survives and has a SuperWheelchair grafted directly onto his spine instead.
* HeroicWillpower: Carmack and Goat possess this. [[spoiler: As when Carmack is infected and is AxCrazy enough to attack on impulse, he resists it and tells Samantha to "shut it down.[[note]] Referring to the facility[[/note]]" and "It's inside." before he lapses back into violent delirium and Goat, when he reanimates, retains enough of himself to know that he's changing and so kills himself to stop it.]]
* HeroicSacrifice: [[spoiler: Goat]] is killed by an Imp, and infected. He comes back to life early in his mutation. Realizing he is turning, he makes a sign of the cross, before smashing his head repeatedly against a bulletproof window, killing himself.
* ImprovisedWeapon: Destroyer turns the ''entire holding cell'' into one.
* IncorruptiblePurePureness: Anyone. [[spoiler:Chromosome 24 refuses to infect and turn into a monster. Reaper and Destroyer are confirmed as this.]]
* InNameOnly: The film borrows almost nothing from and previous source, not even ''VideoGame/{{Doom 3}}'', which is the biggest inspiration for the film. About the only thing carried over is the demon designs from ''3'', and a ShoutOut with the first-person scene. No demons, almost no Mars (it's never shown, which the games always did), none of the iconic weapons aside from the chainsaw, (the BFG ''almost'' makes it, but suffers from looking and acting nothing like its game counterparts), even the plot is ''completely'' different from any of the the games or novels.
* ItCanThink: The infected seem to retain some cognitive functions at the very least. As the zombified [[spoiler:Dr Olsen]] used a scalpel to attack [[spoiler:Reaper]] and [[spoiler:Goat]]. Again later when the hell knight uses a chainsaw in its fight with [[spoiler:Reaper]], and one hellknight uses a bone-saw to break through the Ark vault walls and get to Earth. Later still, one of the 'demons' disables the computers [[spoiler: in the UAC facility on earth]] to prevent the marines from extending the quarantine countdown. Even lampshaded:
-->'''Kid:''' They're disabling computers now!?
-->'''Duke:''' Yeah, Kid. They're rocket scientists, remember?
* JumpingOffTheSlipperySlope: [[spoiler: Sarge]] near the end of the movie when he orders all the remaining UAC personnel killed, even the uninfected ones. He then clinches it by shooting [[spoiler: The Kid]] when he refuses to follow said order.
* JustForPun: John Grimm's nickname on the team is Reaper. Grimm Reaper. His sister is less than impressed by this, but as John points out:
-->'''Reaper:''' They're marines, Sam, not poets.
* KillEmAll: [[spoiler:Sarge]] orders this word-for-word as the fate of the surviving and definitely uninfected UAC personnel.
-->[[spoiler: '''Sarge:''']] We kill 'em all. Let God sort 'em out.
* [[KickTheDog Eat The Lab Rat]]: An infected Dr Olsen quickly glimpses Goat and Reaper, but instead of attacking them straight away turns back to the cage, grabs a rat and devours it alive in front of them, flashing a brief [[SlasherSmile sadistic smirk]] after doing so and reaching for the scalpel...
* LargeHam: After [[spoiler:getting infected]] near the end of the movie, Sarge proceeds to start hamming it up.
* LeaningOnTheFourthWall: Sarge's [[spoiler: dying words]] could be seen this way, given the level of fame enjoyed by DwayneJohnson:
-->[[spoiler:'''Sarge:''' I'm not supposed to die!]]
* LogoJoke: The Universal logo has Mars instead of Earth.
* LoweredMonsterDifficulty: While the "demons" are inhumanly fast and vicious, and the infected attack on sight for the bulk of the movie, during the first-person shooter scene they suddenly start just standing around posturing a lot, and seem to move much slower. For example: There's a moment where a hell knight bursts through a door and then just stands there roaring while [[spoiler:Reaper]] calmly reloads and then shoots it.
* LudicrousGibs: The hell knight's [[spoiler:death via Reaper's proximity mine.]]
* MakeSureHesDead: After discovering that [[spoiler:some of the previously-thought-dead scientists might reanimate as monsters]], the marines take to [[DoubleTap double-tapping]] any "corpses" they come across.
* NamedAfterSomebodyFamous: Dr. Todd Carmack is named after Creator/JohnCarmack, co-founder of Creator/IdSoftware.
* NoOSHACompliance: Even if they weren't worried that someone in the holding cell could get out, you'd think the UAC would put a lid on the thing (or at least some guardrails at the top) so that valuable research personnel did not accidentally fall in.
* TheNotLoveInterest: Instead of your typical hero/heroine love interest angle, the film uses a familial/platonic bond to great effect: John and Samantha Grimm are estranged but loving fraternal twins.
* OhCrap: [[spoiler: Imp-Sarge's reaction when Reaper throws a live grenade into the teleporter Imp-Sarge was just thrown in.]]
* OffWithHisHead: [[spoiler:Mac]] loses his head to a surprise monster claw swipe from the shadows.
* OnlyKnownByTheirNickname: Though every soldier has a name in the script, most of them are referred to only by their handle ID's. PlayedForLaughs in the case of "Mac."
-->'''Pinky''': You don't look like a "Mac."\\
'''"Mac"''': [[TheUnpronounceable Katsuhiko Kumanosuke Takahashi]].\\
'''Pinky''': So... "Mac."
* OnlyPointTwoPercentDifferent: The movie had an additional chromosome that caused people to become demons or supermen, depending on who they were.
* OohMeAccentsSlipping: Rosamund Pike and Karl Urban's American accents get a bit dodgy during parts of the film.
* OpenMouthInsertFoot: Duke asks Reaper if he let "that fine piece of ass get away", to which Reaper responds "she's my sister."
* OrphansOrdeal: John and Sam lost their parents in an accident at the site when they were kids.
* PalatePropping: Subverted, and in a grislier-than-usual fashion; the monster bites down on the flashlight that was used on its mouth, making the thing go through its head.
* ParentalAbandonment: The Kidís parents up and left him one day. He claims they wanted the TV more than they wanted him.
%%* PersonOfMassDestruction: Destroyer.
* PlayingGertrude: Not an extreme example, but Reaper and Samantha are supposed to be twins and Karl Urban is about six-and-a-half years older than Rosamund Pike.
* PortalCut: How The nanowall does something like this when [[spoiler: Imp-Carmack]] gets caught in it as the thing solifies.
* PreMortemOneLiner: [[spoiler: Like the Kid said, [[SeeYouInHell "Go to hell"]].]]
* RealMenLoveJesus: Goat. He's so religious that he [[SelfHarm self-harms]] when he takes the Lordís name in vain.
* RightBehindMe: [[spoiler: Pinky and the Hell Knight]]
-->[[spoiler: '''Pinky''']]: Aw, there's something behind me isn't there!?
* RuleOfCool: Despite the obvious need to safely contain Chromosome 24 experiments, one would think the UAC would come up with something a little more practical than a massive pit with electrified walls.
* SelfHarm: [[spoiler:Goat]] at one point cuts a cross into his arm because "I took [the Lord's] name in vain." At the same time, it can be seen that he has dozens of other cross-scars on that arm.
* ShootEverythingThatMoves: Sarge's orders when the surviving squad members are about to [[spoiler: head back to Earth through the Ark]].
--> '''Sarge:''' We uphold quarantine. Nothing gets to the elevator back on Earth..... If it breathes: Kill it!
* ShotToTheHeart: While the squad is attempting to revive [[spoiler:Goat]].
* ShoutOut: The introduction of the SpaceMarines is a shout out to similar introduction of the heroes of ''Film/{{Predator}}''.
* SideBet:
-->'''Portman:''' Five bucks says this shit ain't nothing but a disgruntled employee with a gun.
* TheSquad / TheTeam:
** TheLeader- Sarge
** TheHero- Reaper
** TheLancer- Duke
** TheBigGuy- Destroyer
** TokenReligiousTeammate- Goat
** NewMeat- The Kid
** RedShirt- Mac
** TokenEvilTeammate- Portman
** TheSmartGuy / TheChick- Sam
** VoiceWithAnInternetConnection- Pinky
* SuddenVideoGameMoment: The FirstPersonShooter sequence. There's even a point where [[spoiler:Reaper is "killed" by the Pinky monster, but his advanced healing abilities, mentioned by Sam earlier, kick in and he gets another "life."]]
* SurprisinglySuddenDeath
** In the middle of holding off a group of infected scientists, [[spoiler:Duke]] is suddenly yanked through a floor grate by an imp.
** [[spoiler: Mac]]. In terms of time actually spent in the facility, he lasted the shortest, by far. Never even saw his killer, never saw a demon, never fired his weapon.
* TeleportationSickness: Using the Ark isn't shown to be that pleasant an experience, what with the vomiting it may cause. It used to be far worse, subject to "[[TeleporterAccident turbulence]]".
* TeleporterAccident: Pinky lost his lower body in the pastdue to "turbulence" in interplanetary travel.
--> '''Reaper''': He means he went to one galaxy, his ass went to another.
* TheCanKickedHim: [[spoiler:Portman]]
* ThisIsForEmphasisBitch: "Semper Fi, motherfucker!"
* UndignifiedDeath: [[spoiler:Portman]]. Granted, he wasn't USING the toilet, but yeah.
* UsedToBeASweetKid: According to his sister, Grimm used to be sensitive and empathetic.
* VerticalKidnapping: How [[spoiler:Portman]] is finished.
* TheVirus: Chromosome 24. Visible in the blood, and transferred via parasitic tongues, bites, or scratches.
** [[spoiler: Although this is a ZigzaggedTrope, depending on the morality or capacity for violence and ill will of the host. If the host doesn't have the potential to (or at the very least possesses less potential) for malicious and violent behaviour, then C24 will act as a SuperSerum, those who do however become infected and turn into monsters.]]
* WalkingArmory: Near the end of the movie when the surviving marines are [[spoiler:clearing the UAC facility back on Earth]], one can clearly see all of the extra weapons they are carrying (taken from the fallen squad members) slung on their bodies.
** [[spoiler:Sarge]] is carrying both [[spoiler:Destroyer's [[MoreDakka chaingun]]]] and the BFG in addition to his own weapons.
** [[spoiler:Duke]] has [[spoiler:Goat's shotgun]] plus his own assault rifle and sidearm.
** [[spoiler:The Kid]] has his two submachine guns plus [[spoiler:Portman]]'s assault rifle.
* WasOnceAMan: [[spoiler: All of the "demons" in the movie are revealed to be this, monsters created by the addition of a 24th chromosome pair]].
-->'''Sam:''' [[spoiler: This thing didn't ''butcher'' Wilitz, it ''is'' Wilitz]].
* WatchingAVideoGame: The penultimate scene is POV with a gun coming out of the bottom right of the screen.
* WhatYouAreInTheDark: When faced with the chance to destroy the data, which could be used to create more mutant monsters, [[spoiler: Sarge]] refuses to do it. Later on, he kills all the personnel despite Grimm telling him some arenít infected. Chromosome 24 is supposed to emphasize this trait in a person... be it good, or bad.
* WouldNotShootACivilian: Kid, when he disobeys Sarge's order to "clear" a room full of unarmed UAC personnel. Sarge doesn't take this well at all.
