->'''Dawson:''' "Oh, how very thrilling, eh, Basil?"\\
'''Basil:''' "All in a day's work, Doctor."

''Basil, The Great Mouse Detective'' in the UK. Released in 1992 as ''The Adventures of the Great Mouse Detective''.

A 1986 Franchise/DisneyAnimatedCanon masterpiece (Number 26) with no MedievalEuropeanFantasy setting, no TrueLovesKiss, and no [[EverythingsBetterWithPrincesses princesses]] (although there ''is'' a [[NoCelebritiesWereHarmed mouse version]] of [[QueenVicky Queen Victoria]]...) More importantly, the reasonable success of this film after ''Disney/TheBlackCauldron'' debacle was able to convince the new senior management of Walt Disney Pictures that their animation department had a future after all.

This AnimatedAdaptation of ''Literature/BasilOfBakerStreet'', a series of children's books by Eve Titus, tells a story of Franchise/SherlockHolmes in a MouseWorld. When toymaker and mechanical genius Hiram Flaversham is {{kidnapped|Scientist}}, his daughter Olivia hires [[GreatDetective the greatest detective in all mousedom]], Basil of Baker Street, to find him. On her way, she is found by the {{Narrator}} and Dr. Watson's CaptainErsatz, Dr. Dawson, just back in London after serving overseas in the military. Basil is reluctant to take the case until he realizes the bat who kidnapped Olivia's father works for his ArchEnemy, the DiabolicalMastermind Professor Ratigan (Creator/VincentPrice).

With the help of his trained hound, Toby, Basil tracks the bat to a human toy shop, but he escapes ''and'' kidnaps Olivia. Ratigan uses her to force her father to complete a robot duplicate of the mouse queen as part of his EvilPlan to take over the kingdom. After learning Basil is on the case, the EvilGenius decides to use this as an opportunity to humiliate and defeat his [[TheRival rival]] once and for all. Basil falls for his trap hook, line, and sinker and, with some encouragement from Dawson, narrowly escapes the DeathTrap in enough time to save the queen and engage Ratigan in a ChaseScene by air that culminates in a gruesome MonumentalBattle at Big Ben.

Oh, and there's [[http://www.youtube.com/watch?v=e2IctxaCPqw a Victorian strip tease]] in a BadGuyBar--sung by [[http://en.wikipedia.org/wiki/Melissa_Manchester Melissa Manchester]], no less--followed up with a BarBrawl.

----
!!This film provides examples of:

* AccidentalMisnaming: Basil constantly gets Olivia's surname wrong. Funnily enough, the one time he ''does'' get it right is when he's addressing [[LastNameBasis her father]].
* {{Adorkable}}: Could briefly be used to describe Basil, of all people, after Olivia's MyParentsAreDead moment. He gets very awkward and tongue-tied before snapping back to his usual self.
** Again with Basil when we first meet Toby.
** Also the scene where he's awkwardly trying to cheer up Dawson. "I say...Dawson, old chap?" with a nervous smile.
* AdultFear: Ratigan arranges to have Olivia kidnapped, and threatens to have her fed to his RightHandCat unless her father cooperates with his demands.
* AgonyOfTheFeet: Olivia stomps on Fidget's foot while he's restraining her. (Made worse by the fact that he only has one foot.)
* AlcoholInducedIdiocy: Professor Ratigan congratulates himself on his outstanding villainy and celebrates with his minions. One of them, Bartholomew, gets so drunk that he unwittingly calls his master a rat (which he is), Ratigan's BerserkButton. He takes Bartholomew with him and serves him up to his pet cat for lunch.
* AllThereInTheScript: Books, actually. The original book series reveals that not only was Ratigan originally a mouse, but also that his first name is [[TheIrishMob Padraic]].
** Miss Kitty's name isn't brought up anywhere in the film, but it can be seen on her character model sheet.
* AlwaysNight. Averted, as the majority of the film (or possibly entire--that last scene is dubious) happens within [[ExtremelyShortTimeSpan just a few hours]] (June 20th-21st 1897, to be precise). Likely the film takes place, ''at least'' within two nights, if Ratigan's comment, "We will have our little device ready by tomorrow evening, won't we?" is any indication.
* AndTheAdventureContinues: At the end of the film, Basil gets a visit from a dame who has another case for him to solve.
* AsideGlance: Fidget gives one when Ratigan frees him from the cat and begins cuddling him.
* AxCrazy: Ratigan towards the climax, when he's enraged.
* AwesomenessByAnalysis: Near the end, Basil escapes Ratigan's killer RubeGoldbergDevice by setting it off at a very precise moment.
** This is established right at the beginning where Basil is able to figure out Dawson's profession and where he came from in less then 3 lines of shared dialogue!
* {{Badass}}: Say whatever you want about Ratigan, but taming a cat and making it into your minion is pretty cool. Especially if you're a rat... I meant, mouse. Same goes for Basil who managed to befriend a dog.
* BadBoss: Don't upset Professor Ratigan, or he'll feed you to his RightHandCat.
** ...or simply toss you overboard when you're weighing him down.
* BadGuyBar
* BattleInTheRain: The climax.
* BatmanGambit: When life gives you lemons, make lemonade; when your ArchEnemy is on your trail, let him find you so you can kill him.
* BerserkButton: Calling Ratigan a rat.
** When Basil tries to press his button by calling him a rat, Ratigan freezes, spawns TechnicallyASmile, informs him that he would have stuck around to watch his death but Basil was late, and walks away cheerfully.
* BewareTheSillyOnes: Ratigan's infamous VillainousBreakdown.
* BigBad: Professor Ratigan.
* BigFriendlyDog: Toby. The emphasis here is on ''big'', since the main characters are mice.
* BigNo: Basil, when discovering that the two bullets don't match.
* BigShutUp: Ratigan, after Olivia starts to bad mouth him when he's escaping.
* BizarreAndImprobableBallistics: The ''idea'' behind the ballistics test is presented fairly well, but the experiment conducted to determine a match has a fatal flaw. Basil holds the ends of the bullets together, and most of the grooves etched into the bullets by the rifling match, except for few. The problem is, if you turn the bullets around in your head so they're side-by-side as opposed to end-to-end, one would be a mirror image of the other! Thus, a cursory glance at them would be all you need to see that they don't match. If Ratigan knew Basil would make such a stupid mistake when comparing the bullets, this could be a case of FridgeBrilliance, as it implies almost ''impossibly'' good foresight.
* BlowingARaspberry: Ratigan's appearance in the Royal Palace elicits {{Dramatic Gasp}}s from the crowd, except one little kid who just razzes him.
* BoomerangBigot: Ratigan appears to despise rats despite being one himself, and calling him a rat is a surefire way to get yourself killed.
* BondVillainStupidity: Justified. Ratigan does build a giant death trap that he leaves our heroes in. However, it is explained that he wanted to stay and watch it, but as the heroes arrived 15 minutes later than he planned, he doesn't have the time to stay. So he rigs a camera to capture Basil's dying moment instead.
* BreadEggsMilkSquick: Fidget has to get "tools, gears, girl, and uniforms".
* BrickJoke: Right before leaving for Buckingham Palace, Ratigan tells a soon-to-be-dead Basil "Now, you ''will'' remember to smile for the camera, won't you?" as he activates his deadly Rube Goldberg contraption which is set to take a picture at the exact moment Basil and Dawson are to die.
** [[spoiler: ...A few scenes later, after Basil's last-minute ingenuity ''very narrowly'' lets them escape the trap, he grabs hold of Dawson, catches Olivia and says "Smile, everyone!" as the picture of the three is successfully taken.]]
* BritishRoyalGuards: Two guards are very easily beaten by {{Mooks}}.
* BunnyEarsLawyer: Basil is an undeniable genius who, when we first meet him, comes off as quite possibly insane.
* ButtMonkey: Ratigan has a tendency to treat Fidget this way.
* CallBack: [[spoiler: Ratigan tells Basil to be sure to smile for the camera which will take a pic of him being offed by the DeathTrap. After Basil manages to foil the trap:]]
-->[[spoiler: '''Basil:''' "Smile, everyone!" ''(click!)'']]
* TheCameo: Franchise/SherlockHolmes himself appears three times in silhouette. In the books, Basil actually lives under Holmes' floor. From his and Watson's dialogue, Holmes is apparently solving the case of the Red-Headed League. And the dialogue is performed by? ''Basil Rathbone''.
** Dumbo appears as a bubble-blowing toy in the toy shop that Basil and Dr. Dawson go to.
** Bill the Lizard from ''Disney/AliceInWonderland'' also appears in the film.
** Toby the dog is from the Literature/SherlockHolmes novel ''The Sign of the Four''.
* CantKillYouStillNeedYou: After Hiram Flaversham refuses Ratigan's command to complete a clockwork robot to impersonate the Queen, and adds insult by calling him a [[BerserkButton rat]], Ratigan barely restrains himself from feeding Hiram to [[TheDragon Felicia]]. When Hiram expresses that he isn't afraid to die, Ratigan [[IWillPunishYourFriendForYourFailure instead threatens the life of his daughter]], Olivia.
* CelebrityParadox: Avoided. Basil lives under the ''real'' Franchise/SherlockHolmes.
* CapeSnag: Basil invokes this on Ratigan towards the climax.
* CaptainErsatz
* CardCarryingVillain: Ratigan likes to talk about how his latest scheme is supposed to be "even grimmer" than his previous ones.
* CatsAreMean
* ClimbingClimax
* ClockPunk: The robot double of Queen Mousetoria that Flaversham makes for Ratigan.
* ClockTower: The Westminster Clock Tower, home of Big Ben, is the location for the final showdown.
* ConspicuousCG: One of the first uses of CGI (after ''Disney/TheBlackCauldron'') in an animated feature, traced from wire-frame graphics onto animation cels and certainly a far more conspicuous user than its predecessor--where ''Disney/TheBlackCauldron'' mostly limited CGI to special effects and stuff (i.e. glittering stars, chroma-keying smoke into the scenes, etc.), ''The Great Mouse Detective'' made extensive and notable use of it in the interior of Big Ben. Very impressive stuff for its time.
* ConspicuouslyLightPatch: Averted in a scene where Basil and Dawson are crawling up some pipes to Ratigan's sewer hideout. One of them bangs their head against a pipe cap after taking a wrong turn, and despite being painted like the rest of the background, the cap rattles.
* CueCard: Mr. Flaversham is forced to read off cue cards while operating the Queen Mousetoria robot.
* CurbStompBattle: The final battle shows that Basil doesn't have any opportunity against Ratigan in a one-on-one wrestle, with Ratigan being several times his size and built like a tank. [[spoiler: A good thing that this is a genius battle.]]
* DangerouslyGenreSavvy: When Ratigan learns that Basil is on the case, he realizes that it is inevitable that the great detective will track him to his lair, so he sets a trap for him there. He also sets up a decoy trap in the bar that fronts his hideout so that Basil will easily avoid it and be lulled into a false sense of security.
* DeadpanSnarker: Basil.
* DeathTrap: Justified, InUniverse, by Ratigan.
--> "I had so many ingenious ideas, I didn't know which to choose. So... I decided to use them all!"
* DetectiveAnimal: Basil, naturally.
* DetectivesFollowFootprints: Basil uses a magnifying glass to follow Fidget's clearly visible footprints in the toy store.
* DiabolicalMastermind: Ratigan, defined by Basil as the "Napoleon of crime" (an obvious reference to Professor James Moriarty).
* DialogueReversal: When Olivia corrects Basil about her name during the movie, he says, "Whatever." Later, when Basil and Olivia part on good terms and he again gets it wrong, Dawson says, "Whatever."
* [[spoiler: DisneyDeath: Basil.]]
* [[spoiler: DisneyVillainDeath: Ratigan.]]
* DistinguishedGentlemansPipe: Basil.
* DistractedByTheSexy: It's quite easy to miss, but Fidget gets his leg stuck in the floor because he is watching the dancers in the bar scene.
* DoesThisRemindYouOfAnything: One hundred percent unintentional, but there's a moment where Basil points to a small circular hole in a pane of glass and calls it "our friend's point of entrance" while sticking Dawson's finger into it. He then shows how if you pull, the glass operates like a door, but still.
* DramaticSitDown: Basil has a bad HeroicBSOD. He can do nothing besides sit there through the HannibalLecture and wait for the death trap to go off. He gets better.
-->'''Dawson:''' "Dash it all, Basil! The queen's in danger, Olivia's counting on us, we're about to be horribly splattered, and all you can do is lie there feeling sorry for yourself!"
* EstablishingCharacterMoment: Basil doesn't appear at all for the first ten minutes or so of the film, letting the plot be established without him. When Dawson and Olivia are at Basil's flat waiting for his return, the movie (and the audience) is completely thrown off by the abrupt entrance of an insane-looking Chinese mouse, brandishing a revolver and screaming "I shall have him!". No sooner do we adjust to this intrusion that we learn that the Chinese mouse ''is'' Basil, wearing a realistic mask and a fat suit. But even after this, Basil utterly ignores the entreaties of the heroes to obsessively test his theory on matching bullets, howling in anguish when he is proved wrong and slipping into a spell of depression. It is only after all this that Olivia is able to get a word in and set the plot into motion, but by now we already know that Basil is ''not'' your typical Disney hero.
** Besides his VillainSong, Ratigan's debut establishes his character quite easily; while threatening Flaversham, he speaks very tenderly about what could happen to his daughter, gently holds the toy he made for her....and squeezes it until it breaks.
* EurekaMoment
-->'''Dawson:''' "If you've given up, then why don't we just set it off now and be done with it?"
-->'''Basil:''' "Set it off... now? Yes! That's it... we'll set the trap off ''now''!"
** And on the villains' side as well:
--->'''Ratigan:''' ''(angry)'' "Oh, I can just see that insufferable grin on [Basil's] smug face..."
--->'''Ratigan:''' ''(smiling)'' "Yes... yes, I can juuust see it..."
* EverybodySmokes: This being the Victorian era and all.
* EvilBrit: Ratigan, albeit with the American voice of VincentPrice.
** Price's accent in the movie still sounds thoroughly American to British ears.
* EvilCounterpart: Ratigan is one to Basil, just as Moriarty is to Holmes.
* EvilFeelsGood: Ratigan says that aloud quite a few times.
* EvilIsHammy: Ratigan. Again, look at who voiced him. It's inevitable.
* Evil Sounds Raspy: Figet is an extreme example.
* ExitPursuedByABear: Felicia, Ratigan's cat.
* ExpressiveMask: Basil as a white rubber Chinese mouse during his introduction (also an example of LatexPerfection, despite taking place in 1897, ''[[AnachronismStew before latex masks were invented!]]'').
* {{Expy}}: Basil to Franchise/SherlockHolmes, Ratigan to Professor Moriarty.
** [[AndZoidberg And Dawson to Watson]].
** Ratigan also bears some resemblance to Mok from ''WesternAnimation/RockAndRule'' according to Creator/JohnKricfalusi's [[http://johnkstuff.blogspot.com/2008/09/rock-n-rule-mok-robin-budd.html analysis of that movie]]
* FacePalm: Basil during "Let Me Be Good To You" after Dawson starts making a fool of himself.
* FauxAffablyEvil: [[VillainSong In song]], Ratigan professes that he has planned his worst crime yet. His mooks gush ''"Even meaner? You mean it? '''Worse than the widows and orphans you drowned?'''"'' The thing is that his thugs asked the question with enthusiasm, and Ratigan was simply having fun the entire time.
* FamilyUnfriendlyViolence: Ratigan's [[NoHoldsBarredBeatdown brutal beatdown]] of Basil in the final scene.
* FantasticRacism[=/=]YouAreWhatYouHate: "I am not a rat!"
* FourFingeredHands: Exceptions being Ratigan (a rat) and Fidget (a bat).
* ForTheEvulz: "You don't know what a ''delightful'' dilemma it was trying to decide on [[DeathTrap the most appropriate method]] for your demise."
* FrothyMugsOfWater: Averted; the drinks in the BadGuyBar are explicitly referred to as beer. Brandy, champagne and sherry are also mentioned.
* FluffyTheTerrible: Felicia, a giant house cat that Ratigan flowers with affection and uses to dispatch his enemies as well as any incompetent lackey.
* FurryConfusion: The movie has anthropomorphic mice, rats, bats, and lizards, but real cats, dogs, and horses, and humans as well.
** Not so anthropomorphic, as Ratigan proves.
* GeniusBruiser: Ratigan prefers to use his brain to solve his problems (if nothing else to preserve his image), but he is ''vastly'' stronger than any other small animal in the movie.
* GettingCrapPastTheRadar: For a G-rated movie, this movie has gotten away with a lot of PG and even a bit of PG-13 material.
** The ''stripping'' mouse named Miss Kitty, with this line ''"Hey fellas/I'll take off all my blues!"'' Everything from her bow to her shoes is blue.
** "Hey fellas, / There's nothin' I won't do, just for you!"
** "So dream on, and drink your beer. Get cozy, your baby's here!" Basil also points out his drinks are drugged. The fact that half the bar is smoking seems to be the least of the worries during this scene.
** "Boys, what you're hoping for will come true / Let me be good to you!"
** Russian version of the song is even more straightforward, with lyrics like: "I want to be tender to you, I want to love y'all!"
* GilliganCut:
-->'''Basil:''' ''(to Olivia)'' "Young lady, you are most definitely ''not'' accompanying us, and [[PunctuatedForEmphasis that! Is! FINAL!]]"
-->(Cut to Basil on the case, accompanied by Dawson and Olivia)
-->'''Basil:''' "And not a word out of you. Is that clear?"
* GoodIsNotNice: Basil comes across as somewhat rude, especially early in the film, which makes him a good contrast to the FauxAffablyEvil Ratigan. Fitting, since the original Holmes can be somewhat of a {{Jerkass}} SmugSnake himself at times.
** Although he ''does'' slowly grow out of it, as seen when he tries to comfort Dawson. Granted, he doesn't actually ''apologise'' for his rant, but it's clear from the look on his face that he regrets being so harsh.
* GoryDiscretionShot: You see the [[ShadowDiscretionShot shadow]] of Felicia just before she eats Bartholomew the mouse.
* GoodSmokingEvilSmoking: Basil smokes a pipe while Ratigan smokes a cigarette (complete with long stemmed filter a la [[Disney/OneHundredAndOneDalmatians Cruella de Vil]]). When Basil disguises himself as a thug, he swaps out his pipe for a cigarette.
* GPSEvidence: The brandy, coal dust, and salt water on Fidget's list.
* {{Hammerspace}}: Ratigan's shoes.
* HeelFaceReturn: Fidget does this in a sequel comic.
* HeterosexualLifePartners: By the end, Basil manages to entice Dawson into staying by having him help with a new client, whom Basil immediately gives a SherlockScan, impressing Dawson yet again.
* HeroicBSOD: Basil undergoes a near-fatal one after he falls for Ratigan's trap.
** Dawson has a minor one after Olivia is kidnapped by Fidget.
* {{Homage}}: "Elementary, my dear Dawson". The entire movie, really, especially one scene where the silhouettes of two men who are obviously Holmes and Watson are visible discussing a case. The Holmes expy even shares a name with probably the most famous actor who played Sherlock. (So would that make this a [[IncrediblyLamePun Holmsage]]?)
** In fact, in ''The Adventure of Black Peter'', Holmes mentions he's known as (Captain) Basil around the Sumner area, though that much is coincidence. There's also Toby the dog, whom Holmes used in ''The Sign of the Four''.
* IAmNotWeasel: The professor HATES being called a rat; he's actually a "big mouse".
* IdiotBall: Basil and Dr. Dawson grab it pretty hard in the toy store by not realizing that someone had to have set off all the toys' mechanisms and that they didn't just wind themselves up. Basil should have instantly realized that whoever turned them on must have done so to provide cover for himself, and Dawson messed up by just letting Olivia wander off by herself.
** Ratigan's intelligence tends to drop considerably when he's very angry, causing him to act on impulse several times to his own detriment.
* [[IHaveYourWife I Have Your Daughter]]
* InfantImmortality: Partial aversion. Olivia doesn't die but she is put in life-threatening danger several times. Most notably she is almost crushed to death by the clock gears in Big Ben, saved literally at the last second by Basil. Ratigan also threatens to kill her unless they let him escape.
* InsistentTerminology: "I AM NOT A RAT!" [[note]]Ratigan has five fingers on his hands, er, forepaws, while all the other ''real'' mice have four fingers. Not to mention his yellow eyes, sharp teeth and thicker tail.[[/note]] This is different from the books, where he actually is a mouse.
* IntoxicationEnsues: Dawson, after drinking a drugged pint of beer.
* IronicEcho: [[spoiler:Basil's ringing of Ratigan's little dinner bell (as Ratigan would use to call Felicia) before Big Ben strikes the hour, the bell's vibrations knocking Ratigan off to his demise.]]
* JumpScare: Twice by Fidget; when he breaks into Flaversham's shop in the beginning of the film, and when he hides in a cradle while inside the human toyshop.
** NightmareFace: Both times.
* KarmicDeath: [[spoiler:Ratigan dies because of the bell he used to execute his incompetent followers.]]
* KickTheSonOfABitch: [[spoiler: Ratigan throws Fidget off his ship after he asks if he can toss Olivia overboard.]]
* KidAppealCharacter: Olivia.
* KidnappedScientist: Flaversham is a toymaker, but he qualifies. His skill with making mechanical toys had applications for chicanery that Ratigan made forcible use of.
* {{Knighting}}: It's certainly implied by the picture in the newspaper article at the end.
* LargeHam: Ratigan is one of Disney's largest. In fact, Creator/VincentPrice said that this was his favorite role, and that he had a lot of fun with it. What's more, he also professed to being "flattered" that all of Ratigan's songs were written specially for him so that he could act as over-the-top as possible.
** Mr. Price was prone to making wild, over-the-top hand gestures and such while acting, which the animators worked into Ratigan's character as well.
** There's also the incredibly expressive, hyperactive unless quite visibly depressed, always overdramatic Basil himself.
*** Barrie Ingham (Basil's voice actor) was ''also'' given to dramatic gesturing. The animators had lots of raw material to work with!
** Basil's most notably hammy moments are:
--->"Young lady, you are most definitely not accompanying us! AND THAT IS FINAL !!!
** and...
--->"Set it off now. Set it...off...now? . ''(laughs madly)'' Yes, yes, we'll set the trap off NOW!!".
* LaserGuidedKarma: Felicia escapes Toby by jumping over a high wall, only to be [[FamilyUnfriendlyViolence torn apart by the royal hounds on the other side]].
* LastNameBasis: (Padraic) Ratigan, (David) Dawson, and (Hiram) Flaversham.
* {{Leitmotif}}: Basil, Dawson and Olivia all have their own respective themes that frequently show up in the film's score: Basil's theme is also used as the main title music, Olivia's is also the tune her father's dancing music box mouse plays, and Dawson's theme prominently features a bassoon.
** Ratigan has two themes; a solo clarinet and a dark french horn/bass combination.
* LuckyTranslation: Basil is called "Basil Holmuis" (hole-mouse) in Dutch. Yes, that's a real word.
** The Italian title for the film is ''Basil l'investigatopo'', a play on words with "investigatore" ("detective") and "topo" ("mouse").
* MissKitty: Miss Kitty Mouse.
* MissingMom: Olivia [[NeverSayDie doesn't]] [[ParentalAbandonment have]] one, as she rather bluntly tells Basil.
* MouseWorld
* MsFanservice: Miss Kitty.
* MusicalTrigger: Sets off the DeathTrap.
* MyParentsAreDead: Basil, depressed about failing to catch Ratigan yet again and playing the violin to console himself, dismisses Olivia's request that he find her father with, "Surely your mother knows where he is." Olivia responds, "I don't have a mother," and Basil's playing comes to a screeching halt.
* MythologyGag: Plenty homages to original Holmes novels :
** The first meeting between Basil and Dawnson reflects the first meeting between Holmes and Watson in [[AStudyInScarlet "A Study in Scarlet"]]. In both cases Holmes/Basil calls his future partner a "Doctor" and explain how he deduced he was a Doctor and that he just came back from Afganistan.
** Toby is Holmes's dog from the story "The Sign Of the Four".
** [[TheCameo Holmes]] is voiced by Basil Rathbone (who played Holmes in 14 movies!) and his lines are from the story "The Adventure of the Red-Headed League". Basil himself is named after Rathbone.
** The final fight between Basil and Ratigan reflects the final fight between Holmes and Professor Moriarty in the story "The Final Problem".
** When Dawson says (commenting on Basil's deduction skills) "It's amazing", Basil replies, "Actually it's... elementary, my dear Dawson", a reference to Holmes's so-called catchphrase.
** Another Holmes catchphrase ""The game's afoot!" is used by Basil as well.
** Ratigan's Voodoo Doll looks just like Basil in Paul Galdone's illustrations in the original "[[BasilofBakerStreet Basil of Baker Street]]" stories.
* NaturalWeapon: Ratigan, at the end, is revealed to have long, deadly sharp claws which are [[ArtMajorBiology conveniently retractable.]]
* NiceMice: Most of them, at least.
* NoCelebritiesWereHarmed: Queen Mousteria, a clear analogue of Queen Victoria.
* NoHoldsBarredBeatdown: Towards the end of the movie, Ratigan mercilessly attacks Basil while shouting "There's no escape this time, Basil!" That Ratigan is usually [[AffablyEvil more friendly]] than that only makes his [[MoodWhiplash suddenly vicious]] attack feel even more intense.
* NoKillLikeOverkill: Ratigan's ridiculously over-the-top DeathTrap for Basil, which is set up so the detective will be snapped by a mousetrap, [[WhyDontYouJustShootHim shot by a gun]], impaled by a crossbow, [[HalfTheManHeUsedToBe chopped in half by an axe]], [[AnvilOnHead crushed by an anvil]], and [[ArsonMurderAndJaywalking get his picture taken]]. As he explains, he had trouble deciding on any one way to kill Basil, so he decided to use ''all'' of them.
* NominalImportance: Some characters, including "[[MsFanservice Miss Kitty]]", are only named in the credits.
* NotGoodWithPeople: Basil. He is downright rude towards Olivia and seems to be very very uncomfortable while trying to cheer up Dawson.
* NothingPersonal: Implied by Ratigan towards Dawson; as he sets the DeathTrap, he tells him, "Sorry chubby. You should have chosen your friends more carefully." (Or maybe he just decides to kill him ForTheEvulz.)
* ObsessionSong: "Goodbye So Soon"
* OffModel: The very unfortunate DVD cover that was formerly at the top of this page. See its completely different art style [[http://www.coverbrowser.com/image/finnish-dvds/752-1.jpg here]].
** How about the current DVD cover artwork? Basil and Olivia don't look too bad, despite Basil having five fingers (usually he has four) and Dr. Dawson's eyes looking rather odd.
* OffstageVillainy: Ratigan lists his villainous exploits in his opening song, but as his Card-Carrying villainy would suggest [[NoodleIncident we never get to see them]].
* OminousMusicBoxTune: In the toy shop, when the cradle that Fidget hides in is wound up.
* OneWingedAngel: As part of his VillainousBreakdown, Ratigan reverts to his monstrous feral rat form. He proves ''incredibly'' dangerous, nearly killing Basil.
* PantyShot: Olivia, a few times. Most notably when Fidget shoves her into the bottle.
* PaperThinDisguise: Basil and Dawson's sailor disguises. [[LampshadeHanging Lampshaded]] by Ratigan.
** Which is particularly odd, considering that Basil clearly has much more convincing disguises at his disposal, such as the large Chinese mouse he was dressed as earlier in the film when he was introduced. Why he doesn't don another costume like that when going after someone who knows perfectly well what he looks like and will undoubtedly be able to see through a tiny stick-on mustache and a change of clothes is rather baffling, particularly for someone as smart as he is.
* ParentService: "Let Me Be Good To You".
* PermaStubble: Ratigan, although technically speaking it's just the fur color.
* PluckyGirl: Olivia shows shades of this near the climax of the film.
-->'''Olivia:''' "Just wait! Basil's smarter than ''you!'' He's going to put you in jail! He's not afraid of a big, old, ugly '''''rat''''' like you!"
-->'''Ratigan:''' "Would you kindly sit down and '''[[foldercontrol]]

[[folder: [[Big Shut Up shut up! ]]
]]'''"
* PrimalStance: When Ratigan's animal rage returns him to all fours while attacking Basil, also exposing his claws and baring his teeth.
* PunnyName: Many in the foreign language editions -- besides "Ratigan". For instance, the Italian Dawson is named "Topson", with "topo" meaning "mouse."
* PuttingAHandOverHisMouth: Basil does this to Dawson, as does Ratigan to Olivia--before she bites it.
* TheReasonYouSuckSpeech: Basil uses the Queen Victoria robot to tell Ratigan where to go.
-->'''Basil:''' "Most assuredly... you insidious fiend. You're not my Royal Consort! You're a cheap fraud and impostor. A corrupt, vicious, demented, scoundrel. There's no evil scheme you wouldn't concoct. No depravity you wouldn't commit. You, Professor, are none other than a foul stenchus rodentus, commonly known... ''(Basil pops out)'' as a ''sewer rat!''"
** Also, Dawson gives a rather angry one to Basil while he's in the middle of his HeroicBSOD, which actually ''helps'' Basil, leading to his EurekaMoment detailed above.
* RedEyesTakeWarning: If Ratigan's body starts to quiver uncontrollably and his eyes become blood-red, '''''START RUNNING FOR YOUR LIFE!'''''
** This is used as a blink-and-you'll-miss-it bit of foreshadowing early on in the film. When we are first introduced to Ratigan, after he has just completed his Villain Song, he turns to Fidget, asking if everything is going as planned. When Fidget nervously reveals that he accidentally led Basil onto their master plan, Ratigan momentarily flies into a blinding rage, his eyes glowing a deep, bloody red, going so far as to sic Felicia on Fidget. But once Ratigan realizes that he can use Basil's involvement to his advantage, his rage subsides, but the redness in his eyes lingers until the next scene.
* RidiculouslyCuteCritter: [[http://images4.wikia.nocookie.net/__cb20100306022349/disney/images/7/74/Mousedetective017.jpg Olivia]].
* RightHandCat: Felicia. Oddly, she's also a RightHandAttackDog, though obviously not in the literal sense.
** She is the Hand Cat, of a RAT.
* RoyalsWhoActuallyDoSomething: Downplayed but the Queen is seen helping tie up Ratigan's mooks. She can also be seen helping with trying to restrain Ratigan before he escapes.
* RubeGoldbergHatesYourGuts: The clock tower ends up being a huge death trap. It doesn't work, but man, if someone didn't outdo themselves thinking it up.
* RunningGag: "Everything will be fine, Miss Flanghangar!" "[[AccidentalMisnaming FLAVERSHAM!]]" "Whatever."
* SchmuckBait: "[[VillainSong The World's Greatest Criminal Mind]]" has the line ''You're the tops, and that's that''. Considering Ratigan's BerserkButton, why would the chorus end a line with anything that could rhyme with 'rat'?
* SecondFaceSmoke: A woman at the tavern blows smoke at Dawson when he tries to apologize for bumping into her. Ratigan does it to Flaversham while holding him prisoner.
* SesquipedalianLoquaciousness: Being the genius he is, Basil does this quite a bit, confusing or impressing Dawson at times.
* ShameIfSomethingHappened:
--> '''Flaversham:''' "You can do what you want with me. I won't be a part of this-this... this evil any longer!"
--> '''Ratigan:''' "Oh, very well, if that is your decision. Oh, by the way, I'm taking the liberty of having your daughter brought here."
--> '''Flaversham:''' "O... Olivia?"
--> '''Ratigan:''' "Yes... I would spend many a sleepless night if anything ''unfortunate'' were to befall ''her''."
--> '''Flaversham:''' "You... Y-You wouldn't!"
--> [Ratigan crushes Olivia's doll his hand]
--> '''Ratigan:''' [[SuddenlyShouting "FINISH IT, FLAVERSHAM!"]]
* SherlockHomage: "Basil, blatantly so."
* SherlockScan
* ShesGotLegs: Miss Kitty the bar singer has some of the most shapely, curvaceous legs ever animated.
* ShooOutTheClowns: Ratigan dumps his lackey Fidget (who provided most of the film's comic relief) out of his dirigible, into the Thames River. That's a big clue that things are about to get dark and intense. Cue VillainousBreakdown and NightmareFuel inside Big Ben.
* ShoutOut: A few:
** To ''Franchise/LupinIII'' during the clock tower fight, a Shout Out to ''Anime/TheCastleOfCagliostro'' specifically.
** Disney also references its own movies with a Disney/{{Dumbo}} toy in the toy shop and [[Disney/AliceInWonderland Bill the Lizard]] as one of Ratigan's [[{{Mook}} mooks]].
** Basil shares his name with Basil Rathbone, an actor famous for his portrayal of Sherlock Holmes and whose image often inspired the image the detective has in popular culture.
*** Bonus points: Basil Rathbone's voice appears, through the magic of archived dialog, as the voice of Sherlock Holmes.
** A potential one to British comedy ''Series/FawltyTowers'' as Manuel's pet rat shares his name with this mouse.
* ShowgirlSkirt: Kitty's number has her remove a normal skirt to show a [[FluffyFashionFeathers short, feather skirt]] underneath.
* SissyVillain: Ratigan (before he turns into a [[NightmareFuel psychotic, feral rat]] at the end) is quite possibly one of Disney's most cold-blooded villains... and yet he surrounds himself with pink and purple fabric, fashionable capes, and sings songs while being carried around by his hired boys.
* SlippingAMickey: Basil and Dawson are given drugged drinks sometime in the bar. Basil is GenreSavvy enough to test his drink first, but Dawson isn't so fortunate.
* SmokingIsCool
* [[SmugSnake Smug Sewer Rat:]] Ratigan is [[TemptingFate standing on the very]] ''[[TemptingFate edge]]'' [[TemptingFate of the clock hand]] after Basil has fallen off, and as he's laughing in victory, he doesn't notice that the clock is chiming the Westminster Quarters...
** In general, this is what Ratigan is at his core. He just manages to hide it ''very'' well.
* StaggeredZoom: Done on Ratigan right before he goes nuts during the Big Ben scene.
* SteamPunk: The [[spoiler:robotic Queen Victoria duplicate and its control system]] that Flaversham built out of cobbled-together gears and toy scraps commonly found in the 19th century, as well as Ratigan's favorite mode of aerial transportation, can only be explained as this.
* StepfordSmiler: Ratigan's a Type C.
* SuperSenses: Basil is able to detect drugs in his beer by simply dipping his fingertip into the drink and licking it. [[FridgeBrilliance Which is similar to what real-life mice and rats do if they suspect poison.]]
** He also tastes a sheet of paper to get more evidence on its origins. [[SherlockHolmes His mentor]] often sniffed evidence, including corpses, but taste is more of a mouse thing.
* TechnoBabble: Basil spouts some while [[AwesomenessByAnalysis analyzing]] Ratigan's DeathTrap. See WritersCannotDoMath down the page.
* TermsOfEndangerment: Ratigan calls Olivia "my dear" as he is pulling her away from her father.
* TheRenaissanceAgeOfAnimation
* TheyHaveTheScent
* ThrownFromTheZeppelin: Fidget the bat.
* [[DramaticThunder Thunderous Confrontation]]: As the standard for Disney animated films, Basil and Ratigan's big fight on Big Ben near the end is accompanied by a strong thunderstorm, which clears up once [[spoiler: Basil and Ratigan fall off the clock, and Basil survives thanks to using a piece of Ratigan's getaway blimp.]]
* TitleDrop: The last line of the film. The original title would have been "Basil of Baker Street", the name of the book series. Characters utter "Basil of Baker Street" quite frequently throughout the film, so if ExecutiveMeddling hadn't changed the title, there would have been a lot of title drops!
* TranquilFury: Throughout most of the movie, Ratigan repeatedly gets angry, but manages to reign it in and remain FauxAffablyEvil as he threatens and murders his henchmen. [[VillainousBreakdown During the climax, however...]]
* UndersideRide: Dr. Dawson rides in a mouse-sized compartment beneath a stagecoach.
* UnusuallyUninterestingSight: Queen Mousetoria's guests aren't too quick to pick up on the fact that her double looks a bit... [[UncannyValley robotic]].
* UnwittingPawn: Basil falls for Ratigan's ploy perfectly, throwing him into a temporary HeroicBSOD at the shock of his own stupidity.
* VictorianLondon
* VillainousBreakdown: Ratigan, towards the final battle, turns from a formal and composed rat into [[OneWingedAngel a hulking and monstrous one]]. It's even the trope's picture on [[VillainousBreakdown/{{Film}} the film page]]!
** Made even ''more'' frightening is the fact he was previously so FauxAffablyEvil. It serves to show just how insane and feral his breakdown has left him, especially since he had, up to now, succeeded in keeping Olivia and her father separated from each other. When he sees Basil successfully reuniting them before his very eyes, this accelerates Ratigan's breakdown.
* VillainSong: "The World's Greatest Criminal Mind"
** "Goodbye, So Soon" could maybe count, too!
* TheWatson: Dr. Dawson.
* WhenTheClockStrikesTwelve: Mercifully averted. However, the [[http://greatmousedetective.webs.com/img/gmdinhouse.html original script]] called for Big Ben to strike midnight instead of ten o'clock like in the film.
* WorldsSmallestViolin: A surprisingly literal example, as Basil ''is'' a mouse playing a violin just his size...
* WorthyOpponent: Subverted. When Basil confronts Ratigan and starts speaking, it looks like he's invoking this trope, but it's actually the lead-in to an insult:
-->"Ratigan, no one can have a higher opinion of you than I have... and ''I'' think you're a slimy, contemptible sewer rat!"
* WretchedHive: The seedy pub. They DO serve Rodent's Delight, after all...
* WritersCannotDoMath: Really, Basil... just what ''is'' "the square root of an isosceles triangle", exactly? (Maybe Basil just ''is'' so much smarter than us that he knows how to calculate the square root of an isosceles triangle!)
** You could also argue that he's thinking so fast that he's not verbalizing every step of his mental process, and there's some stuff in the middle that he just skips.
** A real-life example could be famous mathemagician Arthur Benjamin as evidenced by this [[http://www.youtube.com/watch?v=M4vqr3_ROIk clip]].
* XanatosSpeedChess: Ratigan ''and'' Basil are good at this. Ratigan when he realizes Basil is hot on his tail (no pun intended), and Basil [[spoiler: when escaping Ratigan's trap.]]
* YouCanLeaveYourHatOn: The BadGuyBar has a burlesque performance (consisting of a juggling octopus and a trio of period-accurate strippers) for entertainment. You know, for kids.
* YouDirtyRat: "SEWER RAT!"
* YouHaveToHaveJews: Hiram Flaversham.
