* Samantha "Sam" Sparks in ''WesternAnimation/CloudyWithAChanceOfMeatballs'' was secretly a nerd in her school days but hides her brains behind the facade of the pretty, ditzy weathergirl for fear of being stigmatised. It adds another layer to the character that she is voiced by Creator/AnnaFaris who is more well known for playing genuinely ditzy characters.
* ''WesternAnimation/IceAge'': Sid kept going on about how Diego is [[WhyDidItHaveToBeSnakes afraid of water]], and subtly teaching him how to swim, saying that most animals can swim when they're babies. [[ChekhovsSkill It comes in handy when the area is flooded, and Sid's unconscious.]] Diego jumps into the water, swims to Sid, Crash and Eddie, and hoists them onto a rock. Sid then states that everybody can swim when they're babies... except tigers.
-->'''Sid:''' I left that part out.
* ''Disney/BigHero6'': At the begining of the movie, Hiro goes to a back-alley robot fighting competition with a pathetic-looking robot, and shyly asking if he can fight too. After getting beaten in a couple of hits he asks if he can bet more money for a second chance. When the second fight starts he drops the shy attitude and shows his robot's true talents by utterly destroying the rival's robot.

* ''Bill Cosby: Himself''
-->'''Bill''': ''(on being incompetent fathers who use incompetence to get out of chores)'' You see, we are dumb, but we're not so dumb.
* Captain Jack Sparrow, ''Franchise/PiratesOfTheCaribbean''. You might think he's quite a harmless fellow when you lock him in chains, but if you start a 10 minute long conversation with him, he'll probably [[TalkingYourWayOut talk you into opening his chains]], [[CombatPragmatist steal your pistol and threaten you with it]], make a break for it and steal the ship you should be guarding before you can even realize what the hell just happened. And when you reach out for your pocket to get the whistle and call the guards you'll notice that your wallet is also missing...the quotes below give great examples:
-->'''Norrington:''' No additional shot nor powder, a compass that doesn't point north...''(looks at Jack's sword)'' And I half expected it to be made of wood. You are without doubt the worst pirate I've ever heard of.
-->'''Captain Jack Sparrow:''' But you have heard of me.
-->''(Shortly after, when their ship is stolen by ''two people'', including Jack)''
-->'''Lt. Groves:''' That's got to be the best pirate I've ever seen."
-->'''Norrington:''' ''(acidly)'' So it would seem.
** In ''At World's End'', referring to Jack again,
--->'''Lt. Groves:''' Do you think that he [[ThePlan plans it all out]], or just [[IndyPloy makes it up as he goes along?]]
--->''[Cut to scathing look from Cutler Beckett.]''
* James Kirk in the new ''Film/StarTrek'' film practically turns this into an art form, frequently acting like a [[HandsomeLech womanizing idiot]] or [[TheFool playing the fool]] throughout parts of the film. However, it quickly becomes clear that he's not nearly as stupid as he leads people to believe, effectively beating the supposedly unbeatable [[UnwinnableTrainingSimulation Kobayashi Maru]] through rather ingenious means and then [[spoiler: stopping Nero's [[RoaringRampageofRevenge rampage of revenge against the Federation]]]]. Prior to joining Starfleet, it's even stated by Pike that Jim's the only "genius-level repeat offender in the Midwest."
* ''Film/TheWizardOfOz'':
** I you watch closely, you will notice that the "brainless" Scarecrow is the one who has all the ideas, comes up with the plan to sneak into the witch's castle, and even (at the climax) manages to think quickly enough to use the Tin Man's ax to drop a chandelier on the witch's soldiers. This is even more pronounced in [[Literature/TheWonderfulWizardOfOz the original book]], where he comes up with clever solutions to nearly every obstacle and monster that the Witch of the West and Oz itself throws at them. In both versions, the Scarecrow's dumb act has even [[BelievingTheirOwnLies fooled himself]]. He associates intelligence solely with being a "great brain" or "deep thinker". Since he's not one of those by any means, he fails to recognize his planning, quick thinking, and resourcefulness are ''also'' signs of intelligence.
** In the musical version of ''Theatre/{{Wicked}}'', it is implied that [[spoiler: the Scarecrow, actually a transformed Winkie prince, ''knew'' he was the most intelligent of the group, but faked stupidity so that he could join up with Dorothy and return to Elphaba.]]
** Uncle Henry also displays ObfuscatingStupidity:
-->'''Miss Gulch''': I'm all the lame for the bite on my leg.
-->'''Uncle Henry''': You mean she [Dorothy] bit you?
-->'''Miss Gulch''': No, her dog.
-->'''Uncle Henry''': Oh, she bit her dog! ''Whacks the gate closed onto Miss Gulch.''
-->'''Miss Gulch''': No.
* ''Franchise/{{Zatoichi}}'', in the series of movies of the same name, posed as a harmless blind masseur (he really was blind) until it came time for either intimidation or the mass slaughter of the EvilMinions.
* ''Film/BlindFury'', an American version of Zatoichi set in 1980s America, has the main character acting like a foolish and unassuming drifter. When set upon by a pack of thugs, he pretends to accidentally take them all out with a PlankGag and other seemingly innocent movements.
* In the 2006 ''Film/PinkPanther'' remake, it is revealed that Inspector Clouseau could [[spoiler: speak Chinese all along and figured out who the killer was when the Chinese woman named "Yu" was brought in for questioning. His rant about actually knowing Chinese turned out to be true.]]
* In ''Film/RevengeOfThePinkPanther'', a character expresses the (erroneous) belief that Clouseau's blundering is actually a version of this.
* Budd from ''Film/KillBill'' is depicted to be a drunken redneck who works as a bouncer for a titty bar. Nonetheless he has shown a [[WarriorPoet philosophical side]] and is the only Viper to get an advantage on Beatrix Kiddo, by faking unawareness that she's hiding around his trailer and blasting her with rock salt when she busts through his door. In fact, [[spoiler:Budd is the only of the vipers not to be killed by The Bride (well, Elle is not actually ''shown'' dead, but is at least very thoroughly screwed).]]
* Silent Bob, from Creator/KevinSmith's ''Franchise/TheViewAskewniverse'' appears to be little more then Jay's silent companion, only less exuberant and dumber. It turns out that he's quite knowledgeable. Silent Bob may seem smarter than Jay because his friend is very loud. In ''Film/{{Mallrats}}'', Silent Bob apparently won his eighth grade science fair by turning his mom's vibrator into a CD player with "[[NoodleImplements chicken wire and shit]]"
* Yoda in ''Film/TheEmpireStrikesBack'' is introduced this way, pretending to be an irritating little creature who steals food and squabbles with R2 before finally revealing himself to be the ancient and powerful Jedi master. It's all a SecretTest of Luke's patience.
* JackieChan tends to play these kinds of characters, particularly in ''Film/RushHour'', when he allows Chris Tucker's character, Carter, to believe he doesn't speak English. [[spoiler: Carter gets him back, though, when he reveals that he can speak Chinese just fine. The Screwups Reel makes it quite clear, however, that Tucker himself can't, and since he doesn't speak Chinese in the second movie either, it's possible that Carter only knows the basics of the language or learned just enough for the prank.]]
* In both the 1940 and 1920 versions of ''The Mark of Zorro'', Diego de la Vega plays the featherbrained fop to lull the corrupt Governor Quintero, while, as the masked swashbuckler Franchise/{{Zorro}}, trying to frighten Quintero out of the country. And the 1974 made for TV movie with the same title. Frank Langella's portrayal of foppish Diego de la Vega is the greatest bit of the film.
* The janitor in the horror film ''Film/DisturbingBehavior'' pretends to be mentally handicapped because it causes people around him to drop their guard and become "interesting."
* In ''Film/DirtyRottenScoundrels'', [[spoiler: Glenne Headly plays an extremely ditzy poor little rich girl who is an obvious target of the two cons, Creator/SteveMartin and Creator/MichaelCaine. Turns out that she was counter-conning them from the beginning.]]
* [[spoiler:Doofy, the killer,]] in the first ''ScaryMovie''.
* In ''Film/TheUsualSuspects'', [[spoiler:Verbal Kint, pretending to be a weak-willed and crippled sap who was taken advantage of by Dean Keaton, rather than the diabolical crimelord he is.]]
* In ''Film/SupermanIII'', villain Ross Webster's assistant and girlfriend Lorelei acts the part of the DumbBlonde but is secretly highly intelligent (when alone she reads Immanuel Kant's ''Critique of Pure Reason'' and disputes one of Kant's arguments). As a result she's able to outwit Ross and his sister.
* In ''Film/HorseFeathers'', Connie plays up her football ignorance to try to get Professor Wagstaff to share his secret signals. She overdoes her childlike ditziness, so either he sees right through the ruse or he thinks she needs to snap out of it.
* Subverted in ''Film/TheCourtJester'': some of the villains, believing the title character is either an assassin they hired or a RobinHood-esque resistance leader, believe he's doing it. In fact, he's actually a carnival performer who really is that twitchy and bumbling.
* Sir Creator/RogerMoore's and Creator/PierceBrosnan's Film/JamesBond use this several times. Once they drop the act, run like the wind.
* [[LampshadeHanging Lampshaded]] in ''Film/{{Scream 2}}'', when Dewey claims he is using a form of this trope:
-->'''Dewey''': "How do you know that my dimwitted inexperience isn't merely a subtle form of manipulation, used to lower people's expectations, thereby enhancing my ability to effectively maneuver within any given situation?"
-->''(a brief pause, then Gale starts laughing)''
* In ''Mr. Baseball'', Tom Selleck plays an American baseball player who signs up with a Japanese team. The team's manager appears not to know English through most of the film, causing grief for Selleck's character when he finally finds out.
* ''Film/TrueLies'' does this beautifully several times, though it borders on ridiculous when Harry calls the obvious nuclear warhead an espresso machine...of course at that point it's clear he was being sarcastic to annoy the terrorists.
* ''Film/SummerOf42'' has its underage protagonist employ some of this to [[TrojanGauntlet obtain some condoms]] from a pharmacist. When asked what he wants them for, he says they're actually for his (nonexistent) older brother and that he assumes they're for filling with water and dropping on people from a roof.
* In ''Film/DumbAndDumber'', the kidnappers only ''think'' Harry and Lloyd are doing this.
** In the sequel, Harry actually plays it straight, admitting he already figured out that Lloyd was faking his depression before Lloyd admitted it himself, pulling off a prank to make Lloyd think he needed a kidney.
* In ''Film/{{Maverick}}'', Bret Maverick pulls this off effectively in an early scene where he invites himself into a TabletopGame/{{poker}} game, saying, "I promise that I'll do nothing but lose for at least an hour." For the first hour of so he indeed loses every hand. From the second hour of the game on, Maverick winds up cleaning out the rest of the table. When one fellow gambler accuses him of cheating, Maverick explains, "What do you think I was doing for the first hour? I was learning your tells." This sets the tone for the rest of the movie, in which Maverick appears to be bumbling his way through the West, but in reality is as shrewd and sly as anyone else in the movie.
* Bruce Wayne in ''Film/TheDarkKnightSaga'', he pretends that he is [[RichIdiotWithNoDayJob a vain, stupid, frivolous and superficial playboy millionaire]] in public, all to make people never suspect of him being Franchise/{{Batman}}. For example, in ''Film/TheDarkKnight'', Joker causes chaos by threatening to blow a hospital unless the people kill a man who claims to know Batman's identity. When someone tries to ram the police vehicle carrying the man, Bruce pulls a vehicular TakingTheBullet. Afterwards he acts like it was an accident, but still shoots a knowing glance towards the man whose life he saved.
* ''Film/TheHallelujahTrail:'' Walks Stooped Over, the Sioux chief who does all of their negotiating in badly translated sign language, is revealed at the end as speaking perfectly good English.
* Both Mr. Green and Colonel Mustard both embody this throughout most of the film ''Film/{{Clue}}''. Although, depending on which ending you get, it's completely genuine for Green.
* In ''Film/TheAvengers2012'', Natasha Romanoff uses a variation of this combined with a WoundedGazelleGambit as an interrogation technique. She lets the interrogat-ee think that they've outwitted her and plays the part of the helpless prisoner, then waits for them to [[YouJustToldMe shoot their big mouth off]] while they're gloating about how she failed to live up to her reputation. Then she [[PlayAlongPrisoner breaks out]] and kicks the shit out of them. This scene is just {{foreshadowing}} for [[spoiler:when she pulls a similar trick on Loki.]]
* David "Mo" Rutherford, in ''Film/TheStuff''. He portrays himself as a quite inept and dimwitted lowlife, introducing himself in a particularly obnoxious manner. The trope quite soon lampshaded when one character, impressed with Mo's ingenuity in placing a small microphone into the pockets of everyone in present at the meeting on the night before, comments "you're not as dumb as you appear to be". To which he responds "Nobody is as dumb as I appear to be".
* Mr. Shhh (played by Steve Buscemi) in ''Things to Do in Denver When You're Dead.'' He's introduced with narration showing up in a slightly disheveled suit and slumped shoulders. He proceeds to kill a couple of muggers without breaking a sweat.
* In ''Film/MyFellowAmericans'', former Presidents Kramer and Douglas run for their lives, trying to discover the criminal genius who framed them for a bribery scandal. [[spoiler: Turns out it was the supposed fool of a Vice President, Ted Matthews, who arranged to remove both the former Presidents and his own boss with a single scandal.]]
* ''Film/IronMan2'':
** Vanko shows he's both fluent and eloquent in his early face-to-face confrontation with Tony Stark, but speaks to Hammer in broken, barely intelligible English just to dick with the guy. Later on he acts only barely competent at engineering and technology, convincing Hammer that the best he can do with the Hammer suits is to make drones and then later on that the best he can make the drones do is "salute." Hammer naturally underestimates him as a result.
** Tony pulls this himself - even though everyone knows how smart he is (largely because his AwesomeEgo won't let him keep his mouth shut about it), he plays at being much less intelligent at human interactions than he really is, and more of a dissipated playboy than he really is. This is particularly noticeable in the fight scene in Iron Man 2 between him and Rhodes in the Mk II. While before he was dancing as if drunk and shooting liquor bottles with his repulsors, during the fight he's just as quick as Rhodes and gives easily as good as he gets.
* Big time in ''Film/NowYouSeeMe''. [[spoiler:Rhodes is always one step behind the Four Horseman and is always outwitted by them. He's actually the Fifth Horsemen, deliberately pretending to fall for all their tricks to make sure the authorities are always one step behind the Horsemen.]]
* In ''Film/DjangoUnchained'', Stephen plays the role of a submissive house slave in public. In private however, he's actually smarter than his master and serves as Candie's personal adviser.
* ''Film/MissCongeniality'': Most of the girls come across as the stereotypes Gracie associates with pageants, but for the most part this is because the girls are all very well-trained in saying exactly the right things to get them the points needed to win, even if makes them seem brainless. [[spoiler:Cheryl, who spends most of the film appearing to be a sweet and gentle DumbBlonde, turns out to be a nuclear physicist.]]
* ''Film/{{Fracture 2007}}'': As part of his scheme, Ted Crawford, who's being tried for attempted murder, initially presents himself as a layman unacquainted with courtroom procedures but who decided to represent himself by exercising his basic rights, presumably out of hubris. When he later pushes for an acquittal based on lack of admissible evidence by the prosecution, he reveals that he has quite a bit of legal expertise, which the annoyed judge quickly notices. You can especially see it when he uses the legal phrase "motion for judgment of acquittal", not having demonstrated any familiarity with them earlier.
* The Film ''Film/TheIdiots'' is about a bunch of middle class teenagers and 20-somethings that pretend to be mental retarded in order to fuck with people. And of course when the leader of The Idiots actually encounters someone mentally retarded he flips completely out on them. Needless to say the movie does not end to well.
* ''Film/ExMachina'':
** Although Nathan is obviously a genius as an inventor and can talk technical if he wants to, he tends to play up his flaws and act easier to exploit than he really is. He might have affected or at least exaggerated his drinking problem and hipster/bro personality so that Caleb would be suckered into trying to trick him.
** [[spoiler:Kyoko pretends to be obedient and guileless until she can [[TheDogBitesBack get her revenge on Nathan]]]].
* In ''Film/TheCaptainHatesTheSea'', Schulte the PI is following Danny Crockett on the cruise ship, trying to get the $250,000 in bonds that Danny has stolen. Danny's OutlawCouple partner Janet, aka "MIchigan Red" and posing here as an innocent librarian, manipulates Schulte into falling in love with her in order to distract him from the bonds. Schulte appears to be falling for their scheme, until he's shown holding Janet's rap sheet, revealing that he knows everything.
* This is Billy's act in ''Film/WhiteMenCantJump''; he pretends to be a goofy white guy so that when he plays basketball for money, no one will realize how good he actually is.
* Harry Deane, of ''Film/{{Gambit}}'', seems intelligent, but horribly naive and prone to screwing up everything. In actuality, he's the mastermind of a greater con than what he claims to be perpetrating]].
