->''"There is not one [[TheVerse universe]], there are many; a {{multiverse}}. We have [[InterdimensionalTravelDevice the technology]] to travel between universes. The travel is highly restricted and [[SpacePolice policed]]. There is not one... you, [[AlternateSelf there are many]]. Each of us exists in [[PresentDay present time]] in [[AlternateUniverse parallel universes]]. There was balance in the system, but now a force exists who [[MultiversalConqueror seeks to destroy]] the balance so that he can become... [[TheChosenOne The One]]."''
-->--OpeningNarration.

An action movie from 2001, starring JetLi and JetLi with [[RuleOfThree Jet Li]] in a minor role, born in the wake of the ''[[Film/TheMatrix Matrix]]''-inspired BulletTime craze, directed and co-written by James Wong.

The story takes place in a [[TheMultiverse multiverse]] composed of 125 parallel worlds. Gabriel Yulaw, a former interdimensional law enforcer, is forced to kill one of his other selves in self defense. This action accidentally leads him to discover that the life energy is redistributed among the surviving versions of Yulaw, making them stronger and faster. Soon afterward, he drops out of the force and begins actively hunting down all his alternate selves in order to become the most powerful being in existence. He makes it to 123, and only a single target prevents him from becoming [[ThereCanBeOnlyOne The One]].

----
!!''The One'' contains examples of:

* ActingForTwo: Several actors play counterpart characters from the different dimensions; Jet Li plays both protagonist and antagonist, plus a few additional ones that we see getting killed off. Each character is significantly different from the other; CarlaGugino plays Gabe's loving wife and Yulaw's rather trampy-looking consort. [[spoiler: She also plays his wife's BackupTwin in another universe.]]
* AGodAmI: What Yulaw hopes to achieve after killing all of his AlternateUniverse counterparts.
* AHellOfATime: When [[spoiler: Yulaw is imprisoned after failing to become The One]], he finds it's not so bad, as he receives what he wanted anyways: [[spoiler: a place where he is the most powerful of all]].
* AllThereInTheManual: The movie's official website, now shut down, included a lot of background material. In it, it is revealed that Yulaw was not the first to try this trick. There were at least two other interdimensional criminals who went around killing doubles. One of them did it for someone else.
* AmbitionIsEvil: Yulaw. At least, when his ambition is to become a PhysicalGod and defy the normal laws of physics in the multiverse. It doesn't help when Jason's character suggests that COMPLETING the killings could very well destroy the universe the last killing took place in.
* ArmorIsUseless: Surprisingly averted. All of the armor worn by SWAT team members in both universes deflects bullets impressively well; the armor worn by the SWAT leader escorting Lawless is even shown deflecting a dozen bullets during a slow-motion sequence, and the officer is just in pain, not killed. When Yulaw shoots anyone with his pistol, he generally has to aim for limb shots to put anyone down (save the oddly-unarmored multiversal police).
* {{Badass}}:
** BadassNormal: Roedecker. He's an ordinary human (or at least as ordinary as any multiverse enforcement officer) who is able to go toe-to-toe with Yulaw and fight evenly with him for about a minute and a half.
*** According to the [[AllInTheManual now-defunct official website]], Roedecker is ex-Secret Service in his home Alpha Universe (the MVA HQ).
** The film practically runs on "Rule of Badass".
* BadassBoast: Yulaw's speech at the end:
-->'''Yulaw:''' I am Yulaw! I am ''nobody's'' bitch! ''You'' are all mine. I don't need to know you. ''You'' only need to know ''me''. I will be The One!
* BifurcatedWeapon: The movie begins with two very similar scenes of a prisoner being transferred, each in another universe. The cops' equipment is one of the differences; In the first scene, their rifles have attached shotguns.
* BittersweetEnding: [[spoiler:Though Gabe lost his wife and is now a wanted murderer, Agent Funsch sends him to a "happy" [[UtoPia utopian]] universe where LosAngeles is apparently "America's Cleanest City" and meets that universe's version of T.K. [[HereWeGoAgain the same way he met her in his universe]]]].
* BluffTheImpostor
-->'''T.K.:''' That first time we met at the bookstore, did you ever imagine we'd end up in a mess like this?\\
'''Yulaw:''' Even if I had known, I still would have done it.\\
'''T.K.:''' ''(turns the gun on Yulaw)'' It wasn't a bookstore.
* BolivianArmyEnding: [[spoiler:For Yulaw. Except that he doesn't seem to mind fighting an endless number of enemies for what may be eternity--in fact, being the most powerful man around is exactly his dream.]]
* BuddyCopShow: While not a TV show, Funsch and Roedecker have the usual CowboyCop and ByTheBookCop relationship dynamic.
* BulletproofHumanShield: Somewhat justified because the human shield was wearing a bulletproof vest.
* BulletTime: Yulaw fights at a much higher speed than normal human opponents, so he's able to beat the ever-living crap out of six SWAT officers before they even hit the ground.
** He then runs away from cop cars who clock him at 50 mph.
** The final fight features both Yulaw and Gabe going into this mode for a good portion of the fight, as [[BattleAmongstTheFlames sparks from damaged factory machinery slowly fall around them]].
* CarFu: Yulaw ''literally'' wields two police motorcycles like clubs and beat the living daylights out of the unfortunate cops who rode them mere seconds ago.
* ChekhovsGun: The mark left on Gabe's finger by his wedding band.
* ConservationOfNinjitsu: In universe, and very literally, as conservation of life force. Each time a multiverse version of a person dies, the life force is spread among the remaining duplicates. Thus, by the time there are only two left, both have superhuman powers.
** Also invoked at the ending, where [[spoiler:Yulaw's apparent penalty is to fight wave after wave of inmates in a penal dimension that seems to be ''swarming'' with them.]]
* CrapsackWorld: It's implied by Roedecker that Funsch's home universe is one, although his biography on the official website implies that the Beta Universe isn't that bad. It's just that Funsch was LAPD, and that 'verse's LA is a crapsack city, where everyone is, apparently, a combatant.
* CrystalSpiresAndTogas: [[spoiler: After Good Law finally subjugates Yulaw, he is dumped on a world like this as a "reward" for his services, largely because he is now a wanted felon with no family in his home universe.]]
** It might also be suggested that the Alpha Universe, in which the Multiverse Authority is headquartered, could be like this as well.
*** According to the official site, the Alpha Universe isn't much different from any other, except for the presence of quantum tunneling tech (the only universe to develop it) that allows interdimensional travel. While it does have a political and economic effect on some, it largely does not affect the vast majority of people. For example, one of the interdimensional criminals heads a mercenary squad that hides out in another universe and participates in conflicts in the Alpha Universe, using an illegal quantum tunneling device, when someone pays for their services.
* CurbstompBattle: Yulaw against any non-superpowered human (excepting [[BadassNormal Roedecker]]).
* DecoyProtagonist: [[spoiler:Lawless. He's played by Jet Li, so the natural assumption from anyone who'd seen the trailer would be that he's either the hero or the villain. Turns out, he's neither.]]
* DodgeTheBullet
* DoubleVision
* [[spoiler:TheEndOrIsIt: Yulaw still lives, albeit in a Penal Colony in the Hades Universe, and will stop at nothing to become "The One".]]
* EvilCounterpart
* EvilRedhead: Yulaw's [[spoiler: escort/fellow conspirer, one of T.K.'s other multiverse selves, who helps him escape.]]
* FaceHeelTurn: Yulaw used to be a really good MVA agent until he found out what happens when you kill an alternate self.
* GettingCrapPastTheRadar: Yoo Fuk Law, one of Yulaw's victims.
* GoodNewsBadNews: First variety.
-->'''Yulaw:''' The good news is you're not crazy. The bad news is...''[starts shooting at him]''.
* InSpiteOfANail: Presumably all or most or Yulaw's multiverse counterparts also have the name Law in some form or another.
** We at least know in 3 different universes, Jet Li's character has Carla Gugino's character as a wife or significant other.
* InterdimensionalTravelDevice: There's a quantum tunneling device which allows the interdimensional police to track criminals and, obviously, allows them to travel to different universes.
* LaserSight: Funsch's guns use alternating blue and red targeting lights that, while looking futuristic, aren't very practical in a shootout. Then again, he isn't able to hit Yulaw even once.
* LightningBruiser: Yulaw and Gabe
* MeaningfulName: Some of the parallel universes are named after mythological figures; Anubis Universe, Monoceros Universe, Hades Universe, etc.
** The Stygian Penal Colony.
* MirrorMatch: Gabe and Yulaw in their ultimate confrontation.
* TheMultiverse
** We get to see maybe a half-dozen different versions of Law at his hearing, including the criminal Lawless and the goofy-looking, blonde Sven Law.
*** According to Creator/JasonStatham's character, one of Law's counterparts is either gay or a woman (specifically, he says "married to a man"). This appears to be the only thing he mentions that bugs Law. Possibly because he can't figure out which case it would be.
** Roedecker is an interdimensional law officer in one world and a gas station worker in ours.
** T.K. is an Evil Redhead in one world, a wife in another, and a [[spoiler: has-yet-to-meet Gabe "Good" Law]] Veterinarian in another.
** Gabe is good friends with fellow LAPD officer Bobby Aldrich in our universe while, ironically, Bobby is a jailed felon wanting to kill Lawless, another version of Gabe, in another.
** AlGore became president in another world, and [[GeorgeWBush Bush]] in ours. [[note]]Not a big stretch: in fact it took several improbable events (90,000 people in Florida voting for Ralph Nader, Palm Beach County having a butterfly ballot, etc.) to make it come out the way that it did. A good example of the ripple effect.[[/note]]
** According to the website, the Drakhan Universe has an element that doesn't exist in any other that is illegal to import into the Alpha Universe, as it can be easily used to build weapons that aren't picked up by metal detectors.
* MySuitIsAlsoSuper: While clothes do get damaged, eventually, Gabe bringing down a pole with a single kick apparently does no damage to his shoe.
* NoOSHACompliance: The climax takes place in just such a factory. A couple of isolated, detonated explosives, and suddenly the entire building is a shower of sparks and flame. But at least the walkways can handle guys leaping twenty feet into the air before landing on them.
* OneManArmy: Yulaw and Gabe
* PenalColony: An entire penal universe even, aptly named "Hades" no less.
* PermissionToSpeakFreely: Parodied.
* PunchedAcrossTheRoom: Both Yulaw and Gabe can do that. Yulaw likes to do that after briefly going into a superspeed mode.
* ReplacementGoldfish: Gabe ends up [[spoiler:being sent to a universe where an alternate version of his wife is still alive.]]
* RedHerring: Funsch goes into a twenty-second GunPorn-esque spiel about the high-tech machine-pistol he's carrying to Gabe Law. [[spoiler: He gets off maybe half a dozen ineffective shots with it before it gets destroyed]].
* RedshirtArmy: The SWAT teams in both versions of Los Angeles, as well as most of the multiversal police, are little more than speedbumps at best to Yulaw. The exceptions would be Roedecker and Funsch. The only time any uniformed police manage to seriously impair Yulaw is when Gabe is backing them up.
* RequiredSecondaryPowers: While sped up, both Yulaw and Gabe are able to perform feats that, realistically, would require certain other abilities not mentioned in the film, such as gripping the ground while running at 50 mph, so they don't start bouncing up and down on every step. Yulaw is able to also exert amazing control of his body while in mid-air.
* RichardNixonTheUsedCarSalesman: Decorated MVA Agent Roedecker's counterpart in our reality is encountered working as a gas station attendant.
* RuleOfCool: And nothing else.
* ShoutOut: One of the prisoners says "[[{{Deliverance}} he's got a pretty mouth]]" in the final scene. [[CurbStompBattle What follows, though...]]
** ''Film/FinalDestination'', James Wong's previous film, can be heard playing on TV just as T.K. is heading out to see Gabe at the hospital.
* SpacePolice: The Multiverse Authority (MVA).
* SpottingTheThread: At one point both Gabe and Yulaw are knocked unconscious and no one can tell them apart. [[spoiler: They have a narrow window to send the bad guy to the inescapable dimension and don't know who to send, until Agent Funsch sees the tan line from Gabe's wedding ring.]]
** [[spoiler: An eagle-eyed viewer may be able to tell which is which even before Funsch spots the tan line: Yulaw tied the arms of his jacket around his waist, while Gabe removed his entirely.]]
* SuperStrength: See the above example with the motorcycles. Then there's the fact that both Gabe and Yulaw are strong enough to punch each ''other'' several feet away and break heavy machinery.
* ThereCanBeOnlyOne: The premise.
* TakeAThirdOption: Rather than kill Yulaw, [[spoiler: they manage to teleport him to a prison dimension.]]
** Yulaw invokes this in his scene with Roedecker.
--->'''Roedecker:''' ''[holds up bomb]'' First choice: give up. Second choice: die.\\
'''Yulaw:''' ''[snatches bomb]'' Third choice.
* TeleportationSickness: Even Yulaw becomes helpless after a transit between dimensions, allowing him to be arrested.
* TellMeHowYouFight: Yulaw uses a style that favors attacking in a straight line ([[https://en.wikipedia.org/wiki/Xing_Yi_Quan Xingyiquan]]), which reflects how focused he is on achieving his goal. Gabe uses a more circular style ([[https://en.wikipedia.org/wiki/Baguazhang Baguazhang]]), showing that he is more about harmony and balance. This plays directly into their duel, where Yulaw has the advantage on a straight and narrow catwalk, but gets owned once they move to more wide-open ground and Gabe is able to get behind him.
* TitleDrop: A few times. Some from Yulaw and Gabe.
* UnstoppableRage: Subverted during the final confrontation between Gabe and Yulaw. Gabe, thoroughly enraged at [[spoiler: T.K.'s murder]], assaults Yulaw directly with raw strength and aggression, playing into Yulaw's strengths and allowing Yulaw to effectively counter and pummel him. It isn't until Gabe stops and goes into a state of [[TranquilFury controlled rage]] that lets him take advantage of his strengths that he's able to defeat Yulaw.
* WhatCouldHaveBeen: Originally, the film was supposed to star [[DwayneJohnson The Rock]] as the main character, but he chose to do ''TheScorpionKing'' instead. Imagine two doubles giving each other the "eyebrow".
** JackieChan was approached for the project but turned it down because of his policy of never playing the bad guy.
* WithGreatPowerComesGreatInsanity: Basically what defines Yulaw.
* WorthyOpponent: Gabe, being the final target, has gradually become this to Yulaw as the life-force from the deceased other versions has also been distributed to him making him equally stronger and faster.
** Even for a normal human, Roedecker was able to hold his own [[spoiler:for at least 2 to 3 minutes]].
* XMeetsY: ''Franchise/{{Highlander}}'' with AlternateUniverse [[AlternateSelf counterparts]] instead of Immortals.
** ''Franchise/{{Highlander}}'' meets ''Series/{{Sliders}}''.
