A 1991 Japanese SF[=/=]action film, directed by Creator/KeitaAmemiya, in which a nigh-unkillable alien creature (Zeiram) arrives in on Earth (landing [[TokyoIsTheCenterOfTheUniverse in Japan]], naturally). It is followed by Iria, a female bounty hunter from another planet who has been pursuing Zeiram. Upon arriving, Iria, Zeiram, and two electrical workers are drawn into an alternate dimension where they only have a certain amount of time to kill Zeiram.

Zeiram was followed by a sequel, ''Zeiram II'', as well as an animated prequel, ''IRIA: Zeiram the Animation,'' which depicts Iria's first encounter with Zeiram. There were also two video games - ''Hyper Iria'' for the Super Famicom and ''Zeiramzone'' for the PlayStation.

!!This film and its followups contain examples of:
* ActionGirl: Iria.
* AlienLunch: Teppei eats a large white cockroach, {{squick}}ing Kamiya heavily. It was actually Iria's, as she is shown eating one in the anime.
* AnimeHair: Iria's hair is considerably spikier in the anime than in the live-action movies.
* {{Bifauxnen}}: [[spoiler:Kei]] in the animation.
* BountyHunter
* {{BFG}}: The cannon that's used to defeat Zeiram's [[spoiler: [[YourPrincessIsInAnotherCastle supposedly]]]] final form.
* CoolMask
* EnemySummoner: Zeiram; also crosses over with CloningBlues and MookMaker when it spawns a whole army of biological weirdos in the animation.
** One of the [[CrowningMomentOfFunny funniest moments]] in the movie is when Zeiram summons an enemy... who ends up just being [[BodyHorror a puddle with a head and half of a torso.]] Zeiram grunts at it while pointing forwards, and the two argue in an alien language, presumably about how the puddle literally can't do what Zeiram is telling it to, then Zeiram [[FacePalm facepalms]] and stomps on it.
* FanService: The anime shows Iria taking two [[ShowerOfAngst Showers of Angst]] over the space of six episodes.
* HealingFactor: Zeiram... kinda; [[spoiler: it starts as a HollywoodCyborg, then turns into the cyborg head and a skeleton, then turns into a flying hat, then turns into an EldritchAbomination. It technically can heal, but it [[OneWingedAngel changes form every time.]]]]
* HeroKiller: In Iria: Zeiram The Animation, Zeiram kills her brother Glen.
* JerkWithAHeartOfGold: Fujikuro from The Animation. He postures as TheRival to Glen, Bob, and Iria, but when the chips are down he's willing to cooperate in order to stop Zeiram.
* KickTheDog
* KillUsBoth
* MadeOfIron: Zeiram takes a ''lot'' of punishment.
* NiceHat: Played with in the first movie and the Animation; [[spoiler: what ''looks'' like Zeiram's hat is actually part of its' body. Played straight in the second movie, where it actually ''is'' a hat.]]
* OminousLatinChanting
* OneWingedAngel
* PerpetualMotionMonster
* PocketDimension
* RestrainingBolt
* {{Salaryman}}: The workers from the original movie.
* ShowerOfAngst: Twice in the animation.
* SmallGirlBigGun
* StreetUrchin: Kei.
* UsedFuture: The animation has a nice lived-in feel to it.
* WeCanRebuildHim
* WhipSword
* WholesomeCrossdresser: [[spoiler: Kei]] from the Animation.
