Known as ''Formula 51'' [[MarketBasedTitle in the United States]], this is a 2001 British action-comedy film directed by Ronny Yu and starring Creator/SamuelLJackson.

It's about a pharmacologist named Elmo [=McElroy=] (Jackson) attempting to peddle the formula for a new drug he's created called POS 51, which he claims is "fifty-one times more powerful than cocaine, fifty-one times more hallucinogenic than acid, fifty-one times more explosive than ecstasy."

When the deal goes wrong and everyone involved ends up dead, he realises that his ex-boss, a drug kingpin known as "The Lizard" (Music/MeatLoaf), whom he thought he'd already killed to prevent him seizing the drug for himself, is very much alive and would like revenge. Assisting the Lizard is ProfessionalKiller Dakota (Emily Mortimer), the expat ex-girlfriend of his British contact, Felix [=DeSouza=] (Robert Carlyle). Assisting neither party and trying to help himself is the highly CorruptCop Virgil Kane (Sean Pertwee).

Thus [=McElroy=] is forced to team up with his British contact and find a way to both survive and profit from the debacle.


!!This film contains examples of:

* ArmsDealer: It's one of Iki's many ventures.
* ArtisticLicenseChemistry: The utterly impossible titular Formula 51;
-->'''[=McElroy=]''': ''MDMA utilizes serotonin. Opiates, like heroin, utilize dopamine. Like the sensation you get after sex. Amphetamines increase adrenaline. Cocaine gets those synapses in the brains firing really fast. My product is 51 times stronger than cocaine. 51 times more hallucinogenic than acid. And 51 times more explosive than ecstasy. It's like getting a personal visit... from God.''
** It's likely that [=McElroy=] is just making a sales pitch, but to be able to take a bunch of over-the-counter ingredients and make, well...
-->'''[=McElroy=]''': [[spoiler:''...the most expensive '''candy''' on the market. The drug's a fake, you know. It's bogus. It's what we chemists call a '''[[PlaceboEffect placebo]].''' It's whatever you want it to be. You can run all the tests you want. It will look like the best shit in the universe. But the ingredients, they cancel each other out.'']]
* BritainIsOnlyLondon: A notable aversion, as the film's British parts (ie, almost everything) are set entirely in [[UsefulNotes/FootballPopMusicAndFlatCaps Liverpool]], with London not even getting a ''mention'' (aside from Arthur calling Kane a "cockney twat")
-->'''Felix''': ''Listen to this, I'm in fucking Florida, right. This southern prat comes up and he's like, uh, "Hey! England's small. You must know that John Fuckin' Smith guy, right?" Fucking Smith. I'm like, "oh yeah, yeah mate. That's right. John Smith, yeah, I do know him, but, uh, he doesn't come from England mate, no, he comes from fucking-''\\
'''Felix AND Frederick''': '''''PRICKSVILLE, USA!"'''''
* ButtMonkey: Arthur is clearly Kane's. [[spoiler: He gets revenge in the end]]
* ChekhovsGun: The chemical cocktail [=McElroy=] uses to blow up The Lizard at the start of the film. [[spoiler:Since he takes the drink intended for Iki, it actually does kill him in the end.]]
* ClusterFBomb: Almost everybody in the cast is liberal with these, but special mention must go to Felix and the Skinheads.
* CurbStompBattle: "Battle" is definitely overdoing it, but when the skinheads run at Elmo in the hotel lobby, he quickly finishes them with his golf club.
* CorruptCop: Kane
* CountryMatters: Used casually (though infrequently) by Kane as is typical of the British attitude to the word.
* DramaticGunCock: "Take a puff on this
* FakeAmerican: InUniverse, Dawn speaks with an American accent when she's actually from Liverpool.
* FantasticDrug: POS 51, a drug that is 51 times as potent as other drugs.
* FemmeFatale: Dawn appears to be one of these to Felix, which is slightly strange considering there's no noir elements to speak of present.
* GameOfChicken: Kane has [=McElroy=] and Desouza trapped in an alleyway. They respond by driving straight at him. At first, he charges forward, yelling "Come on, then! Come on!", but [=McElroy=] makes it clear that he's not stopping. Kane loses his nerve, stops and gets shoved out of the way by Desouza's car and in front of an oncoming truck for his trouble.
* GoldFishPoopGang: The skinheads
* GoryDiscretionShot: [[spoiler:The Lizard's death is shown this way... Kind of. The viewer doesn't ''technically'' see him explode due to drinking a heat-sensitive explosive cocktail, but one does get to see the resulting LudicrousGibs cover the windows of the luxury box, then a walkthrough of the room, and Virgil Kane splattered with liquified Lizard.]]
* HeelFaceTurn: Dawn, predictably.
* ImprobableWeaponUser: Golf clubs being used to batter in the skinheads.
* LargeHam: The Lizard is a huge one, and sticks out because nobody else (save of course Creator/SamuelLJackson) comes close. Iki perhaps excepted, but it seems more normal with him.
* ManInAKilt: [=McElroy=] is seen in one for most of the film. The WhereAreTheyNowEpilogue revealing that nobody knows just ''why'' he was wearing it in the first place.
** TheStinger lets the secret out, though: [[spoiler: it's the tartan of his ancestor's slavemaster. [=McElroy=] buys his title and land with a portion of the 20 million.]]
* MarketBasedTitle: Known as ''Formula 51'' in the United States. Why isn't exactly clear, but the pejorative connotations of the original title presumably had something to do with it.
* NeedleInAStackOfNeedles: When the corrupt cop Kane is trying to track Elmo from the airport, he tells his subordinate to look for "a large black man wearing a dress" as reported by his American contact. Unfortunately for the subordinate, in front of Elroy arrive several Middle Eastern men in thawbs (a flowing robe that resembles a dress), several Polynesians in lava-lava (a long cloth worn like a wraparound skirt similar to a sarong), and several Africans wearing dashiki (a long shirt reaching mid thigh or knee). Kane tells the subordinate to follow them all, who then follows them ''in front'' of Elmo.
* NotQuiteDead: The Lizard.
* OopNorth: The film's British sequences are all in Liverpool.
* PercussivePickpocket: Felix does this to Iki's lawyer and takes his car key ''while still in the police station''.
* PopGoesTheHuman: [[spoiler: The Lizard's (real) demise.]]
* PrisonRape: Kane threatens Felix with this; "You fuck me and I'm gonna have you on your hands and your knees with your arse in the air, exposing your rusty sheriff's badge, for the next twenty years!".
* RhetoricalRequestBlunder: An unfortunate miscommunication occurs when [=DeSouza=] asks one of his assistants to "take care" of a nervous chemist. The assistant then goes into henchman mode, [[HilarityEnsues kills the chemist and stuffs him into the car boot]], instead of following the intended meaning which was "[[DontExplainTheJoke look after him]]"
* RoomDisservice: "That fucking chestnut" - inverted. Room service bring up Durant's sausage n' mash while the drug deal is taking place, and his mooks pull and unsuspecting maid into the room and hold her at gun point, believing that they have been rumbled.
* ShoutOut[=/=]TakeThat: [=McElroy=] offers the skinheads a [[Film/TheMatrix red pill or blue pill]] in a combined shout out to the film, CastingGag relating to the original idea of Creator/LaurenceFishburne for his role, and take that to fans who keep mistaking Jackson for Fishburne. Iki also references ''Film/{{Goldfinger}}'' when explaining that the twenty pieces of paper he has in his hands (bonds) constitute £20 million, since he doesn't want to heft gold bars around.
** BTW, you ''[[https://www.youtube.com/watch?v=Xt_BGaDBD2I don't]]'' want [[PottyFailure the red pill]].
* StockBritishPhrases: Elmo and Felix have a [[SeinfeldianConversation Seinfeldian]] CasualDangerDialog on [[https://www.youtube.com/watch?v=-WwJw5lH7pI this;]]
-->'''Elmo''': So LetMeGetThisStraight; "bollocks" is bad, whereas "The dog's bollocks" is good?
* TalkToTheFist:
--> '''Skinhead''': Felix [=DeSouza=], just the wanker I wanted to deal with!\\
'''Felix''': Deal with this! (rams his elbow into the skinhead's face behind him)
* ThereAreNoCoincidences: Felix insists that Shit Happens...
-->'''[[Creator/SamuelLJackson Elmo McElroy]]''': ''No, Shit does '''not''' just Happen. Shit takes time. Shit takes effort. Twenty million dollars worth of effort.''
** In other words, your car breaking down just in time to strand you in the middle of nowhere as a snowstorm starts is a coincidence. A twenty-million-dollar drug deal being busted up by a professional assassin just before you close escrow? That's somebody with more cash than he knows what to do with wanting to make your life hell.
* ThirdPersonPerson: The Lizard
* ThisIsForEmphasisBitch: "Stay down, bitch!" from [=McElroy=] to one of the skinheads.
* TitleDrop: The Lizard refers to Britain as the 51st state during his last scene. [[spoiler: He detonates messily seconds later. Take that you pompous septic!]]
* TheVoiceless: The replacement chemist Durant uses, his muteness being due to a bullet in the neck - the same place another one strikes later, killing him.
* WhereAreTheyNowEpilogue: A very very brief one, showing that [[spoiler:Dawn and Felix settled down together - but only after the game]]. What happens to [=McElroy=] is shown in TheStinger.
