History Film / Doom

* SpiritualAdaptation: Many fans consider this movie to have little in common with the Doom video game it's supposed to be based on, but consider it to have a fair amount of similarities with ''VideoGame/{{Resident Evil}}'',another violent video game from the 1990s, the most obvious reason being that it's about a paramilitary tactical team sent on a rescue mission in a area around a secret lab that find themselves attacked by zombies and mutants that were created by a corporation, more specific similarities include the fact that Reaper has more in common with Chris Redfield than he has with Doomguy, because of his overall appearance, his outspokenness (whereas Doomguy is a silent protagonist) and his feud with his now mutated former commanding officer, along with his protectiveness of his sister.[[spoiler:Sarge's]] betrayal of his unit in the name corporate loyalty which he takes to the point of shooting [[spoiler:The Kid]], is reminiscent of how Wesker acted in the original Resident Evil, the fight between Reaper and the now mutated [[spoiler:Sarge]], is similar to the showdown between Chris and Wesker in ''VideoGame/{{Resident Evil Code Veronica}}'', as is Samantha's refusal to kill fellow scientist Carmack despite his grostesque mutation, being much like Annette Birkin's affection for her fellow researcher/husband William in ''VideoGame/{{Resident Evil 2}}''. In addition, many also consider this movie to be a thiny vieled remake of ''Film/{{Aliens}}'', with certain scenes (such as [[spoiler:Duke's]] Death compared to [[spoiler:Hudson's]]) being almost identical, along with the fact that both are about gung-ho Marines on another planet that are lead by a tough black SergeantRock.

* RomanticFalseLead: While [[spoiler:Duke (Greg)]] is guarding [[spoiler:Dr. Sam Grimm (Reaper's sister)]], there is mild sexual tension as well as affectionate or intimate semi-flirting after the two spend a tiny bit of time together. [[spoiler:Duke]] even thinks she's about to ask for a quickie when she's only asking him to hand over the bone-saw during an autopsy she's performing.

-->[[spoiler:'''Pinky''']]: [[LampshadeHanging Aw, there's something behind me isn't there!?]]

* IncorruptiblePurePureness: Anyone [[spoiler:Chromosome 24 refuses to infect and turn into a monster. Reaper and Destroyer are confirmed as this. Duke and Mac are implied due to the monsters choosing to kill them rather than turn them despite there being clear opportunities to infect them both.]]

* IncorruptiblePurePureness: Anyone [[spoiler:Chromosome 24 refuses to infect and turn into a monster. Reaper and Destroyer are confirmed as this.]]

* BigBrotherInstinct: John will fight the hordes of hell to save his sister.

* DoomedTacticalTeam: Played Straight with the R.R.T.S.

* AllMenArePerverts: Portman and the Kid come across a woman stripping naked. It seems that like many members of the crew she has been driven insane from whatever horrors she has witnessed. They both ogle her for a few seconds, but then the Kid gets embarrassed and steps in to try and help her, and Portman gives him a dirty look for spoiling it. [[spoiler: It turns out that she's mutating into a demon.]]

** [[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."
** This is also how [[spoiler: Pinky]] is killed, dragged by the wheelchair-leg offscreen by a demon.

* 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, what with Chromosome 24 mutating people into monsters. [[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...]]

* 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."
* TheCameo: Brian Steele, the Hell Knight's suit performer, makes a brief appearance out of the suit in the research footage that the main characters watch where he plays [[spoiler: Curtis Stahl (the Hell Knight's [[PatientZero pre-infected human identity]]).]]

* 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.

* DullSurprise: Done deliberately when it’s discovered [[spoiler: Mac]] got his head torn off.

* DyingAsYourself: [[spoiler: Goat]] realizes he's turning into a zombie, and kills himself. [[spoiler: He crosses himself]] before bashing his head fatally against the wall, showing that he was still himself at the time.

* 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.

* RomanticFalseLead: While [[spoiler: Duke (Greg)]] is guarding [[spoiler: Dr. Sam Grimm (Reaper's sister)]], there is mild sexual tension as well as affectionate or intimate semi-flirting after the two spend a tiny bit of time together. [[spoiler:Duke]] even thinks she's about to ask for a quickie when she's only asking him to hand over the bone-saw during an autopsy she's performing.
* 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.]]

* FoldSpindleMutilation: More ''pressed'' than folded, in the case of [[spoiler: Duke's]] death: dragged down through a floor grating with gaps barely wide enough for the monster that seizes him to get its claws through.
* ForegoneConclusion: Any viewer who's familiar with the video game source material will immediately know what Pinky's ultimate fate is [[spoiler: (and possibly have a fairly good idea about the film's main twist of the monsters being mutated humans)]] as soon as they hear his name.

* 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.

* ItCanThink: The infected seem to retain some cognitive functions at the very least. The zombified [[spoiler:Dr Olsen]] used a scalpel to attack [[spoiler:Reaper]] and [[spoiler:Goat]]. The Hell Knight noticeably adjusts its tactics mid-fight against Destroyer when its initial tactics aren't working, later uses a bone-saw to break through the Ark vault door to get to Earth, and is even able to competently use a chainsaw in its fight with [[spoiler:Reaper]]. 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:

* 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. [[spoiler:Note that he isn't infected yet.]]

* LeaningOnTheFourthWall: Sarge's [[spoiler: faux dying words]] could be seen this way, given the level of fame enjoyed by Creator/DwayneJohnson:
-->[[spoiler:'''Sarge:''' I'm not supposed to die!]]

** Reaper confronting and subsequently fighting with [[spoiler:Sarge]] for ordering him to[[spoiler: [[WouldNotShootACivilian kill innocent civilians]]]] mirrors Doomguy's backstory in the original ''Doom'' video games, though it happens at the climax rather than before the beginning.

* NamedByTheAdaptation: [[spoiler: The Doomguy is given the name Reaper.]]

* OhCrap: [[spoiler: Imp-Sarge's reaction when Reaper throws a live grenade into the teleporter Imp-Sarge was just thrown in.]]

* OnlySaneMan: Reaper, obviously, but also, surprisingly, Portman, once the squad finds out that they aren't dealing with a bunch of psychos or escaped animals, but honest-to-god monsters, Portman immediately suggests they evac and call for backup, because, as he points out, they have ''no idea'' what they are up against, they don't know how many "demons" are running around, nor exactly how strong and/or smart they are, and a single one took down [[spoiler: Goat]] without much trouble, he wisely tries to call for backup once he has a moment to himself [[spoiler: sadly, one of the creatures kills him and it seems the S.O.S never got outside the Ark facility.]]

* PortalCut: How the nanowall does something like this when [[spoiler: Imp-Carmack]] gets caught in it as the thing solidifies. Pinky lost his lower half in a botched foray through the Gate.
* PreMortemOneLiner: [[spoiler: Like the Kid said, [[SeeYouInHell "Go to hell"]].]]

* RightBehindMe: [[spoiler: Pinky and the Hell Knight]]
-->[[spoiler: '''Pinky''']]: [[LampshadeHanging Aw, there's something behind me isn't there!?]]

* ShootEverythingThatMoves: Sarge's orders when the surviving squad members are about to [[spoiler: head back to Earth through the Ark]].

** [[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.

* TheVirus: Chromosome 24. Visible in the blood, and transferred via parasitic tongues, bites, or scratches. It converts the host into a rage-filled monstrosity that will kill anything it can find. [[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.]]

* 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'' Willits, it ''is'' Willits]].
* 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 aren’t infected. Chromosome 24 is supposed to emphasize this trait in a person... be it good, or bad.

* AssholeVictim: [[spoiler:Portman]] and [[spoiler:Dr. Carmack]], who performed torturous experiments on prisoners that involved agonizing transformations and live dissection. One of the first things we see Dr. Carmack do is close the door on a panicking lab tech to save his own skin from a Hellknight.

%%** TheSmartGuy / TheChick- Sam

* 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.

* 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.

* BaldBlackLeaderGuy: Sarge.

* 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.]]

* RomanticFalseLead: While [[spoiler: Duke (Greg)]] is guarding [[spoiler: Dr. Sam Grimm (Reaper's sister)]], there is mild sexual tension as well as affectionate or intimate semi-flirting after the two spend a tiny bit of time together [[spoiler: Duke]] even thinks she's about to ask for a quickie when she's only asking him to hand over the bone-saw during an autopsy she's performing.

* IndecisiveMedium: The film adaptation has a suspicious amount of scenes shot in "first person".
