The Rebel Alliance built their entire campaign out of this trope, and its what allowed them to survive when other rebellious organizations didn't. They attacked the heavily-defended Scarif archive installation head-on in what amounted to a near-total suicide mission. The Death Star was built to counter large-scale assaults between capital ships, so the rebels sent in a bunch of snub fighters. When the second Death Star was being built, the Rebels decided to attack it while the Emperor himself was on board (and thus would be at its peak defensively, but this turned out to be a setup).
In the Star Wars Legends timeline, Grand Admiral Thrawn seemed to be the only one who noticed how the Rebels/New Republic always seemed to go for the assaults that would be tantamount to suicide but always seemed to succeed, and thus turned it against them, making him the only one across the entirety of the old Expanded Universe to avert the trope.
An infamous deleted scene from the first movie, A New Hope shows Han Solo, Luke Skywalker, Chewbacca, and Princess Leia strolling through the corridors of the Death Star, their faces uncovered and their street clothes clearly visible, but also conspicuously sporting some stark white utility belts they have stolen from Imperial stormtroopers they've knocked out and/or killed; all in full view of the Imperial personnel! Apparently, the only explanation is that Han, Luke, Chewie and Leia figured that the enemy would find this sight so funny or brazen or unbelievable that they'd dismiss it. (One theory is that George Lucas shot this scene for no other reason than to add to his personal blooper reel.)
Thanks to the events depicted in Rogue One, where Darth Vader clearly sees Leia's ship flying away with the Death Star plans, Leia's statement in the original film that she's out on a diplomatic mission becomes one.
There's a scene in The Phantom Menace where Qui-Gon, who has a death order against him, has to save some pilots that have been captured by battle droids. He simply walks up to the droid commander and asks for them to be released so he can take them to Coruscant. It almost works, too; it takes the confused droid several seconds to comprehend what's going on, and by then he's in lightsaber range.
Jedi Mind Tricks in general utilize this, such as in A New Hope, when Obi-Wan straight-up tells a Stormtrooper "These aren't the droids you're looking for..." on Tatooine.
The Contingency Orders for the Grand Army of the Republic. Order 66, the one that Supreme Chanchellor and future emperor Palpatine used to destroy the Jedi Order states that the Clonetroopers are to kill every single Jedi in case they receive an authenticated transmission from the Supreme Chanchellor stating that the Jedi have rebelled. Order 65, that never gets to be activated, is to arrest the Supreme Chanchellor if he's declared unfit, and use lethal force if necessary.
In The Force Awakens, General Hux gives a speech condemning the New Republic for supporting the Resistance against the First Order. Never mind that Hux and pals have been cruising around in star destroyers that are totally illegal for them to have under their treaties with the New Republic, or that he is giving this speech right before firing a hyperspace Planet Killer at the New Republic's capital.
The Last Jedi begins with Poe claiming to be relaying a message from Leia to General Hux, then claiming that he can't hear Hux's grandiose response and that he's willing to hold for "General Hugs", and continuing to pretend he can't hear them as the extremely confused First Order officers try to respond, only starting to figure out the ruse when Poe refers to Hux as skinny and kind of pasty. When his engines finish charging up for his attack plan and he no longer has to stall them, Poe finishes with a Your Mom joke just because.
I believe he's tooling with you, sir.
American Gangster: Lucas shoots a man who owes him money in broad daylight, then resumes eating dinner on the same block.
Back to the Future: When Biff and his sidekicks chase Marty on the impromptu skateboard, and they approach the manure truck, Marty climbs over their top-down car, through the sidekicks, and lands back on the skateboard.
Be Kind Rewind: When every tape in a video rental place is erased, the leads decide to do 20-minute no-budget versions of the films themselves and hope nobody notices. It didn't work, but customers found the remade films had their own oddcharm, and the store was more successful than it was before the accident.
Big Fat Liar. Like any director would steal a creative writing assignment from some kid's backpack and turn it into his next big movie...
Mark Baum: I don't get it. Why are they confessing? Danny Moses: They're not confessing. Porter Collins: They're bragging.
The 1987 Dragnet movie has the Turn in Your Badge moment as the result of the arrest of a reverend, like anyone would believe that he was organizing a drug rave and trying to offer a woman as a human sacrifice.
The crazier and more over-the-top the actions of the main characters in the movie Fear and Loathing in Las Vegas became, the more likely they were to get away with them. These actions included doing enough drugs to kill a herd of elephants, destroying their hotel rooms, trashing a couple of expensive rental cars, feeding a young girl with acid for a few days, waving around a gun and a knife while twisted, and showing up stoned out of their minds at a police anti-drug convention. The trope was invoked by Raoul Duke at one point, after a truly astonishing sequence wherein he and his attorney chase a pair of cops and their wives down a highway, demanding that they be allowed to sell the cops drugs; the attorney wonders if they'll be arrested, to which Duke points out that nobody would believe the victims if they tried to report it. The scary part is that this is based, however lightly, on actual occurrence.
"It was all over now. We'd abused everything that Vegas lived by; Burning the locals, abusing the tourists, terrifying the help. The only chance now, I felt, was the possibility that we'd gone to such excess that nobody in the position to bring the hammer down on us could possibly believe it."
The author Hunter S. Thompson's reputation is based on Refuge in Audacity. Stories circulate of him intentionally invoking this trope; when his house was found to contain over thirty firearms from handguns up to machine guns, and several sticks of dynamite, Hunter told the police that they were "for home defense."
Ferris Bueller's Day Off: When you get right down to it, this is Ferris Bueller's modis operandi. What kind of parade lets you waltz out from behind the security fence and start changing the music tracks? The crowd absolutely loved it. Also, Ferris almost gets found out at the restaurant when the waiter calls his bluff, but through liberal use of the Indy Ploy he manages to skate through with an even larger, riskier bluff.
Ghost: When Whoopi Goldberg's character signs the million-dollar check, she goofs and apologizes, "I signed the wrong name."
To be fair, this is a totally plausible mistake for a woman in particular, as she might have changed her name upon getting married or divorced.
Indy's encounter with Adolf Hitler. When you're carrying a diary about the Holy Grail, which Hitler seems to want for some reason, and you come face to face with the man himself, do you hide it? No. You take advantage of the book signing you're at and get Hitler's autograph.
While escaping from Berlin in a Zeppelin which hasn't taken off yet, Indy notices an SS officer searching for him and his father. With no place to run or hide, Indy decides the best course of action is to disguise himself as a steward on the Zeppelin, follow the officer around, then hit the officer with a sucker punch when the officer finds Jones Sr and throw the officer out a window. The real audacity comes when Indy explains "No ticket" to the shocked German passengers in clear American English. The other passengers immediately present theirs.
In the Indiana Jones and the Last Crusade adventure game, you also can encounter Hitler. However, you are then given control of Indy and can give him a few different things to sign: the diary, a copy of Mein Kampf (you can give it to a guard at a security checkpoint), or a pass (which lets you go through any security checkpoint without problems). You can also punch Hitler but his bodyguard will make sure you don't live to enjoy it.
In Just One of the Guys, a teenager pulls a Sweet Polly Oliver so she can write an article about life as a guy. When her vacationing parents phone home, her brother informs them that his sister has become a transvestite, and is assumed to be kidding.
Cabin Fever: After very insistently bedding a reluctant partner, and assuring him that she was healthy to ease his angst about there being no condoms available, the girl discovers a set of rashes on her back. These not only mean that she has the sickness that's going around, but also that she probably infected the poor fool she just slept with, too. So to shift the guilt over who did the worst thing to who, she lashes out at the guy for being too rough with her in bed.
Doubly audacious when you rewatch the actual sex scene and realize that if anybody was playing rough, it was her.
Mr. Banks: Will you be good enough to explain all this? Mary Poppins: First of all, I would like to make one thing quite clear. Mr. Banks: Yes? Mary Poppins: (brief pause as if tongue-tied, then wavering slightly tearful, fast tone) I never explain anything.
Julie Andrews's rendition of that line may have made it a subversion, aversion, or justification. She doesn't say it in her usual firm, no-nonsense statement of absurdity.
In Mean Girls, Janis tries to embarrass Regina by cutting holes in her undershirt over where the nipples should be. Regina shrugs, pulls the shirt on anyway, walks around like they're supposed to be there, and ends up setting a new trend.
Cardinal Richelieu: Ah, yes. That is usually the first. Let me see if I remember it correctly. While the English attack from without, the wicked Cardinal undermines from within, forging a secret alliance with Buckingham and placing himself on the throne. But really, Your Majesty, why stop there? I have heard much more festive variations. I make oaths with pagan gods, seduce the queen in her own chamber, teach pigs to dance and horses to fly, and keep the moon carefully hidden within the folds of my robe. Have I forgotten anything?
These lines are delivered in Tim Curry's delightful sneer, from which anyone should run like the wind.
In Leap of FaithThe Protagonist gets out of a speeding ticket by cold reading the police officer and taunting him about his divorce until he gets arrested. He then talks the cop into reconciling with his estranged daughter, and walks away a free man.
In The Men Who Stare at Goats the covert psychic organization is so outrageous, (has pseudo-hippie philosophy and refers to its members as Jedi) that the film can get away with harsh social commentary on the Iraq War that would otherwise make it controversial. The fact that the movie's based on real research the military actually engaged in makes it even more awesome.
In Once Upon a Time in Mexico, Sands walks around wearing a CIA t-shirt (which reads "Cleavage Inspection Agent" in smaller letters underneath). This in itself isn't weird, but then you remember that he's a real CIA agent.
The ending of Teenage Mutant Ninja Turtles II: The Secret of the Ooze Splinter's reaction not withstanding. Consider, four mutant ninja sewer-dwellers duking it out with two super-mutants and a squad of ninjas, in a dance hall, to an impromptu rap song by Vanilla Ice, who then proceed to toss high-fives to the crowd, then hop onto the stage, perform dance moves and shout "Give it up for a Turtle!" None of the people there find this weird. Instead, if their reaction was any indication, they thought it was All Part of the Show (if unusual for a hip-hop performance).
The parade. Joker preempts the Mayor's television address to the city with his own broadcast, and then - after having shamelessly killed dozens of people in the cruelest way imaginable - announces that he is going to hold a parade in the center of town and toss 20 million dollars down to the spectators if they will show up - and they do.
The Riddler uses his technologically enhanced intelligence to locate Two-Face's hideout and then storms in there without invitation. He proposes that he and Two-Face join forces in a scheme to unmask Batman. Two-Face points out that "violating the sanctity of our lair" is an abomination and to attempt it is foolhardy, but he's intrigue by the idea enough to toss the coin on it. If it had come up "bad heads" he'd kill Riddler. It didn't
Die Hard with a Vengeance features John McClane walking around Harlem wearing a sign that proclaims "I Hate Niggers" (the Big Bad made him do it). The street corner at which John is forced to stand is less than twenty yards away from the favorite hangout of a street gang armed with knives. Zeus Carver ominously lampshades this - not five seconds before said gang members spot the sign and come over looking for trouble, and one of them hurls a switchblade that lodges in the sign. John quickly tries to save himself by pretending to be a religious fanatic....which doesn't work. What's most outrageous is that John and Zeus both survive this harrowing encounter with little more than a beer bottle broken over John's head and minor knife wound for Zeus.
Weekend at Bernie's. Two ambitious young men, hoping to climb the corporate ladder, are invited to a weekend long bash at their boss Bernie's beach house, not knowing that a scam they recently uncovered is Bernie's doing and that he plans to kill them. Then Bernie himself is killed by his own hitmen, and the two protagonists try to extricate themselves from the situation by making the guests believe Bernie is still alive, even when his corpse is in plain view.
Jingle All the Way: When Arnold is caught in the bootleg toy warehouse by the cops he grabs a toy police badge from an open box and bullshits like his life depends on it to convince the cops he's an undercover detective. This moment seems more audacious when you remember that impersonating a law enforcement officer is a serious crime in the United States. Had his bluff not worked he would have gone to prison for a long time.
The Walls of Malapaga: Pierre, who is a fugitive murderer, needs to get past the gate at the dock to make it back to the ship that will take him out of Genoa. He tries at night but is stopped by a patrolman. Cecchina, a 12-year-old girl of his acquaintance, suggests that if she goes with him, no one will think to challenge what appears to be a father and daughter out walking. It works, as they stroll through the gates in broad daylight.
In 48 Hrs., Murphy intimidates an entire redneck bar with nothing but his own bravado and Nick Nolte's borrowed police ID, which he flashes while covering the photo.
As Axel Foley in Beverly Hills Cop, he pulls the same stunt repeatedly, flashing his Detroit cop badge rapidly while pretending to be a customs officer, a foreman, etc.
He also manages to get himself a luxury suite in a posh Beverly Hills hotel by claiming to be a Rolling Stone reporter and threatening to write an article claiming the hotel was racist because they "lost" his non-existent reservation.
And he gets into a private country club to confront the Big Bad by putting on an over-the-top Camp Gay act and asking the maitre d' to relay to Victor Maitland that he has herpes. The maitre d' decides it would be better if Axel tells Victor himself.
In The Golden Child, there's a scene where he pretends to be some kind of Federal Agent, and flashes what should be his badge around...if he actually had one on the part of his wallet that his hand is covering.
Outbreak: in order to get to Cedar Falls, Dustin Hoffman's character — a Colonel — comes stamping into the aircraft dispatcher's office demanding to know why he isn't on the passenger list for the next flight to the town. (He's been ordered not to attend.) Variously demanding the dispatcher call his superior officer and then not call his superior, Hoffman gets onto the passenger list and flies because he's intimidated the dispatcher into authorising him.
The climactic battle of Fifty/Fifty (1992) has Jake Wyer and Sam French pinned down by the Tengaran army. Then Jake says he has a plan:
Sam: Alright, what is it?
Jake: Full frontal assault.
Sam: That's your plan? A full frontal assault is your plan?
The Kentucky Fried Movie has "Rex Kramer: Danger Seeker!" who, after dressing up in typical daredevil attire, goes into the middle of a group of black men in an alleyway, shouts "NIGGERS!" and runs off. The sheer ridiculousness of it makes the men stand around looking at each other, giving Rex a 2 second head-start.
In The Lady Eve, a millionaire throws over his fiancee when he learns that she's a notorious con artist. Her revenge involves showing up at his mansion under a different persona and re-seducing him - which works despite her not putting on any kind of disguise whatsoever. She has correctly predicted that he would conclude that, had it really been her trying to fool him, she surely would have changed her appearance in some way; in other words, she looks too much like herself to be her. (It helps that she knows this particular man to be the most gullible chump on the face of the planet.)
Both in and out of universe in Star Trek IV: The Voyage Home. The film crew tested the plausibility of Kirk and company walking around San Francisco dressed like people from the 23rd century by dressing staff in the characters' costumes and having them walk around San Francisco. Nobody gave them a second glance and in fact a longstanding legend is that the hilarious scene where Uhura and Chekov try to ask directions featured genuine response from passersby (including the one woman who provides redundant directions). In the movie itself—with the exception of Chekov—the former Enterprise crew got away with being profoundly weird, with no consequences.
Star Trek V: The Final Frontier: "What does God want with a starship?" Consider that Kirk is challenging either a) The Real McCoy (no pun intended) or b) an alien who holds the fate of Kirk and his crew in the palm of his hand. The potential for that not ending well was immense.
Hong Kong auteur Stephen Chow uses the Mo lei tau comedy style in many of his movies, which in turn relies on this trope.
This is the modus operandi of most Bond villains. Goldfinger convinces multiple crime syndicates to help him rob Fort Knox with the argument that no one will be expecting it.
In Arthur (the 1981 film), Linda Marolla steals a necktie at Bergdorf-Goodman's. The store detective witnesses the theft and follows her out into the street, where he confronts her. After making a snarky comment, she goes on the defensive, pretending she is some kind of official, pulling out a pad and pencil and demanding the detective's name and address. When this fails to intimidate the detective, she yells for someone to find her a cop, at which point Arthur steps in and saves her bacon.
"Statistical fact: Cops will never pull over a man with a huge bong in his car. Why? They fear this man. They know he sees further than they and he will bind them with ancient logics."
G.I. Joe: Retaliation: How do you push for full denuclearization? Launch all your missiles, get the other guys to launch theirs, then abort the launch to get the others to do the same. Bam! Nukes gone.
In Now You See Me, for their first show, the Four Horsemen rob a foreign bank from Las Vegas. When they're arrested, Daniel rightfully points out that they can't very well make the charges stick unless they're willing to admit magic is real. By the time they have an idea of how the Horsemen pulled it off, they've already been forced to release them and still can't actually prove their theory.
Pain and Gain: The other reason the police don't believe Kershaw at first. As Ed says near the end during the trial, "sometimes truth is stranger than fiction".
Catch Me If You Can lives on this. The Villain ProtagonistCon Man, Frank makes a million from writing fraud checks and has to repeatedly pretend to be working professionally in a new job throughout the film such as a pilot, doctor and lawyer. What does Frank do when an FBI agent catches him in his hotel? Pretends to be an federal agent himself whose already caught the culprit and is organizing evidence then simply walks away.
Similar to the Real Life examples of hackers and scammers, Dade does this in Hackers by calling a clueless security guard and rattling off a bunch of technobabble, including such glaring terms as a "BLT drive". Naturally, the guard believes him and tells Dade all the required information.
Wonder Woman (2017): Diana brings her sword into the gala by carrying it down the back of her blue dress, with the hilt and guard very visible. No-one arounds her hardly bat an eye.
Charles: Heterochromia was in reference to your eyes, which I have to say are stunning. One green, one blue. It's a mutation, it's a very groovy mutation. I've got news for you, Amy. You are a mutant. Amy: First you proposition a girl, and then you call her deformed. How is that seduction technique working for you? Charles: I'll tell you in the morning.
Quicksilver blatantly uses his super speed when he first meets Wolverine, Professor X and Beast because he knows no one would believe what they said about him.
Mystique impersonating Richard Nixon and then offering "his" life to spare the rest of the American leadership from Magneto.
At the climax of Guardians of the Galaxy, Big BadOmnicidal Maniac Ronan the Accuser launches into his hammy, bombastic speech, and prepares to destroy everything with a single swing of his weapon.... and then has to stop when Star Lord starts dancing and singing "Ooh Child" and then challenges him to a dance off. The sheer, absolute absurdity of the situation puts a halt to the final ambitions of a mad fanatical killing machine, leaving him standing there flabbergasted and asking "What are you doing." Peter's answer? "Distracting you, turdblossom", buying time for Drax and Rocket destroying Ronan's weapon with their ship-killing cannon.
Susan in The Spanish Prisoner manages to get her car unchecked through a road block by creating a big scene with the protagonist in front of a cop, who loses his nerves and lets them pass.
Thank You for Smoking: Nick Naylor, from comparing cigarettes to chocolate in front of school children, to giving a cancer ridden teenager a fist bump after accusing the anti-smoking people of using the teenager's illness for publicity.
Tad, the Lost Explorer: As Sara explains to Tad, they can't call the police because the case sounds too absurd to be taken seriously.
In Men in Black, it turns out tabloids like Weekly World News are 100% true, which K describes as "the best investigative reporting on the planet". The titular organization allows them to operate and publicly report on normally clandestine extraterrestrial events because only conspiracy-theory nutballs like Norman believe they are even remotely true.
In Deewaar, Vijay is put in charge of protecting a gold shipment from crime boss Samant's men. How does he do this? Why, he goes to Samant and tells him where the shipment will arrive, of course. And after Samant has received the gold and paid him handsomely, Vijay simply steals the gold back.
