''Dèmoni'', known as ''Demons'' internationally, is a 1985 horror film produced by Creator/DarioArgento, and directed by Creator/LambertoBava, son of [[Creator/MarioBava Mario]].

Kathy and Cheryl have received free tickets to a new horror movie. Once inside, though, what happens on the screen starts to happen in the theater, after a fellow theater-goer cuts her face on a ceremonial mask on display in the lobby, and before they know it, the cinema is over-run with man-eating demons.

The film gained a sequel, ''Film/{{Demoni 2}}'', in 1986. There's also several films that got the name ''Demons'' slapped on them even though they nothing to do with the original two.

!!This movie contains examples of:

* AngryBlackMan: One of the patrons, who's quick to take action. [[spoiler: Too bad he dies pretty early.]]
* AntagonistTitle
%%* AnyoneCanDie
* BlackDudeDiesFirst: Played straight with Rosemary, who is first to lose her humanity and turn into a demon.
* BodyHorror: The demonic transformations, especially that of the first victim; also, when a transformed girl starts having convulsions, only for a much more demonic-looking, fully-grown monster to [[ChestBurster erupt from her carcass]].
* ChekhovsGun:
** The mask, supposedly found in the tomb of UsefulNotes/{{Nostradamus}} with a prophecy about "the coming of demons" after being unearthed. Needless to say it doesn't take long for it to fire, though.
** Also the [[spoiler: red motorbike and sword in the lobby. How nice of them to put them all in one spot.]]
* CoversAlwaysLie: One of the video releases' preview/summary implies that the climax of the film will resolve around stopping the movie as it MIGHT be the source of the evil curse. [[spoiler: This actually happens halfway through the film and does nothing at all.]]
%%* DecoyProtagonist: [[spoiler:Cheryl]].
%%* DemonicPossession
* DespairEventHorizon: Some characters go through this when they found a possible HopeSpot in escaping the theater but it's another dead end.
* DownerEnding:[[spoiler: George and Cheryl escape from the theater after dispatching all of the demons and the mysterious mask man, only to find out that the city is over run with demons (one had escaped early in the movie). George and Cheryl manage to escape with a family and as the credits roll, we see Cheryl has turned into a demon and is quickly shot to death as George looks on in shock]].
* EyeScream: Happens (ironically) to a blind man when the first infected shoves her thumbs in his eyesockets. [[spoiler:the man still manages somehow to be the first to leave the cinema; unfortunately, that means by the time anyone else gets out the city is overwhelmed by the demons.]]
* FinalGirl: [[spoiler: [[GenderFlip Gender flipped]] with George, who is the sole survivor after Cheryl ends up being infected]].
%%* {{Gorn}}
* HopeSpot: The group find a possible way out, only for it to be a dead end. And [[spoiler: up until the last minute it seemed like George AND Cheryl were going to at least survive the horror film.]]
* {{Jerkass}}: The older husband in every scene he is in acts like a complete asshole. No surprise that he is one of the first people to get killed.
* OffWithHisHead: [[spoiler:After George's friend is infected by a demon, he forces George to decapitate him with a katana. George then goes off to a demon killing rampage with it]].
* OurZombiesAreDifferent: They're actually under DemonicPossession, and damn fast.
* RedHerring: [[spoiler: The ticket woman seems like she's part of all that is going on. Turns out she's innocent.]]
%%* RuleOfScary: Both films take this trope to a total UpToEleven.
* SlidingScaleOfComedyAndHorror: Both ''Demons'' and ''Demons 2'' are horror movies with a lot of humor, both intentional and [[{{Narm}} unintentional]].
* TheStinger: The end titles for the movie start to roll on the screen, while Cheryl [[spoiler: picks at a wound on the back of her neck]]... [[SubvertedTrope Subverted]] because [[spoiler: the credits disappear, Cheryl turns into a Demon, but is shot and killed before she can harm George. Then the car with George on it disappears from view and the credits finally roll]].
%%* TaintedVeins
* TooDumbToLive: The patrons in the movie theater hear noise in the background and assume it is help coming (it was actually the gang of punks who ran into the theater to hide from the police). So they immediately start to break the barricade they had made despite George, Cheryl and their friends warning them not to. By doing this, all they did was give the demons a chance to break through and attack them.
* TookALevelInBadass: George, big time. Goes from a meek guy just trying to survive the demonic plague to [[spoiler: action hero effortlessly slicing demons apart with a katana.]] The badass intake is enough to rival [[Franchise/EvilDead Ash Williams]].
* TheVirus: A single scratch of their claws, teeth or horns, or a single drop of the demons' [[{{Gorn}} copious bodily fluids]], and you're done for. And unlike most cases, even being killed after getting infected won't help, as they'll simply later revive now fully transformed into a demon.
%%* ZombieApocalypse
* ZombiePukeAttack: The possessed, zombie-like theatregoers do this.
