''Without a Clue'' is a 1988 comedy film, the premise of which is that Dr. Watson (Creator/BenKingsley) created the fictional character Franchise/SherlockHolmes so that he could solve crimes incognito. His published case journals were so popular that he was obliged to hire an out-of-work actor, Reginald Kincaid (Creator/MichaelCaine), to play Holmes. However, Kincaid turned out to be a bumbling, gambling, womanizing drunkard who gladly took all the undeserved credit for solving crimes, and now their relationship is a very rocky one. Watson is just about ready to ditch Kincaid and strike it out on his own, but no-one will believe that Dr. Watson, the archetypical sidekick, is really a GreatDetective, so the two have to get along for long enough to solve one last big case.

%%* TheArtfulDodger
* BadBoss: [[spoiler:Moriarty abandons Sebastian to be arrested at the end.]]
* BatDeduction: A mysterious number is given, and Sherlock Holmes uses a few long and complicated leaps of logic to deduce that it means a specific warehouse. [[spoiler:At the end Holmes and Watson explain to the person who left the clue how they figured it out, and then the victim reveals that the number was simply the address of the warehouse he was being held at.]]
* BecomingTheMask: Reginald has to learn how to be at least somewhat of a detective to help save the day.
* BigDamnHeroes: [[spoiler:Lestrade and his men try nobly at the end, but end up failing miserably and having to dive for cover when the fake Leslie pulls a gun on them.]]

* ChekhovsGun: Kincaid's production of 'The Shadow Of Death' allows him to finish the case, although it was for totally the wrong reasons.
%%* DiagonalCut
* DidNotThinkThisThrough: Kincaid, after falling onto the barge containing the villains' counterfeit money, pours alcohol from a lamp and threatens that there will be "an impromptu roasting" unless they surrender... without realizing that if he sets it ablaze, ''he'll'' catch fire, too. {{Lampshaded}} by Moriarty.
* DidYouDie: Reginald does a variation where he folds it into his own telling.
* TheDragon: Sebastian.
%%* ExternalRetcon
* FakeUltimateHero: Reginald is just pretending to be a great detective.
* FakingTheDead: [[spoiler: Watson]].
* FemmeFatale: The fake [[spoiler:Lesley Giles]] manages to hold much of the police at gunpoint.
* FunnyBackgroundEvent: While Lestrade is explaining the case to Watson, "Holmes" is in his room digging through his closet for a bottle of booze he stashed. We just see, through the open door, articles of clothing and item items being thrown around wildly like in a cartoon, thoroughly mystifying Lord Smithwick who is trying to pay attention to what Lestrade is saying.
* GoneHorriblyRight: Finally fed up with Kincaid's antics, Watson fires him and offers his services to the police. However, he discovers that he's done such a great job building up Holmes as the brilliant detective and himself as just the sidekick that no one will take him seriously and he needs Kincaid to make the act work.
** Also, when Watson is believed dead, Kincaid realizes the police assume he can solve the crime all by himself and realizes just how much they've bought the act.
* GoodScarsEvilScars: Sebastian has a knife scar down one side of his face.
* GratuitousLaboratoryFlasks: Many adaptations of Literature/SherlockHolmes stories both in film and television will fill the background of Holmes' Baker Street flat with chemistry equipment. While this is true to the stories, in which Holmes would sometimes use them, in these adaptations, they're usually little more than set dressing. This tendency to overpopulate the flat with chemistry equipment was parodied here, when Reginald Kincaid (posing as Holmes) actually ''does'' do something with the chemicals - with hilariously explosive results.
* HiddenDepths: After messing up for most of the movie, Holmes proves to be quite skilled at fencing at the showdown, holding his own against Moriarty.
* HypercompetentSidekick: Watson, since Sherlock Holmes is actually an incompetent stooge that fronts for Watson, the true detective.
* KnifeNut: Sebastian's preferred weapons are switchblades and throwing knives.
* LosingAShoeInTheStruggle: Happens to a [[{{Mooks}} Mook]] Kincaid fights with.
* MoodWhiplash: Occasionally. In particular, the rather gruesome murder of the dockworker who catches Moriarty's {{Mooks}} in the act, and the grisly discovery of Donald Ayers' body in the lake.
* {{Narm}}: InUniverse, the reaction to Kincaid in The Shadow of Death.
-->'''Kincaid''' The Shadow of Death. The gripping drama was the last play presented at the Orpheum. It closed after only one night, but not without garnering some praise. Harris in the Daily Telegram said, 'In an otherwise dismal evening, Reginald Kincaid provided some welcome laughs.'
