History TooDumbToLive / Film

* In Skyline, with LA full of alien monsters eating everything that moves, our heroes decide to try and escape in cars with big, growly engines and in broad daylight. Granted, their chances weren't all that good whatever they tried, but at least on foot and at night they had some small hope of evading detection. And let's not even think about the fact that their entire daylight plan was to escape by boat. From flying aliens. Yeah, that will work!

-->Sidney: What's the point? They're all the same -- some stupid killer stalking some big-breasted girl who can't act and who's always running up the stairs when she should be running out the front door. It's insulting.

* The location of ''DeepBlueSea'' implies this form of mentality in the project designers. Genetically-enhanced super-sharks with improved brain functions? Why don't we build the research lab for them in ''the middle of the ocean'' where [[TemptingFate nobody can reach us]] and where, if the overly-sophisticated defense system breaks down, said sharks can escape into the wild and [[GoneHorriblyWrong spread their super-genes around the world]]. [[spoiler:And then SamuelLJackson stands in front of an open pool to give his RousingSpeech, and is eaten by a shark at its climax. It's not clear if the movie [[RealityEnsues did that last bit on purpose]].]]

* Everybody in the movie ''Screamers''. Two sides are fighting a war on a planet. One side deploys the screamers, small burrowing robots. Ok, not so bad. Said screamers are equipped with an adaptive learning AI. Ok, that's risky, but not suicidal. The screamers are also built in an automated factory, and the screamers design and build newer generations of screamers. At this point, the concept moves from "risky" to "out and out suicidal". But the worst part, the thing that make you suspect the designers of the first screamers had a death wish, is the robots programing. The screamers are programed to kill any living thing they encounter, without any Friend or Foe system. Naturally, the screamers kill every single person on the planet. Its the worst case of this trope and Genre Blindness I've ever seen.

* On a more minor example, during a High Speed chase through a densely packed forest in ''ReturnOfTheJedi'', a Stormtrooper turns around just long enough to see if his target died, and promptly crashes into a tree. Look where you're driving! Or... avoid doing a high-speed chase through a densely packed forest to begin with?

*** [[StarWarsExpandedUniverse They did]] ''[[GenreSavvy after]]'' [[GenreSavvy that!]]
* The level of intelligence exhibited by the human race in the film ''{{Idiocracy}}'' can be boiled down to two phrases: [[GroinAttack "Ow, my balls!"]] and "[[CreepyMonotone Welcome to Costco. I love you]]."
* Hud from ''{{Cloverfield}}'' may qualify. Whether his friends are being attacked by parasitic creatures or a gigantic monster is hovering over him with a hungry look in its (many) eyes, it never occurs to him to just ''put the damn camera down and '''do''' something!'' Naturally, [[spoiler: another character loses her life to save him from the parasites]] while his hands are full, and [[spoiler: the hungry monster ends up eating him]]. On the {{Rifftrax}}, Kevin Murphy describes Hud as "straddling a fine line between ''dumbass'' and ''inanimate object.''" There's a reason one of the {{Fan Nickname}}s for the monster is "Darwin".
* Micah from ''ParanormalActivity'' definitely deserves a mention. During the talk with the psychic, Micah asks about using an ouija board to contact the demon. He's told not to contact it at all, as that would constitute "letting it in" and make things much worse. What does he do? He verbally taunts the demon, keeps trying to get in contact with it in various ways, and states repeatedly that he's going to get an ouija board. The crowning point of his stupidity has to be when his girlfriend is freaked out by multiple nightly disturbances, and he tells her that all of the demonic activity is "cool stuff that he has to record". He basically thinks the whole thing is some sort of fun horror game. Pity he's not GenreSavvy in the slightest.
* AlfredHitchcock's ''TheBirds'' has Melanie going up to a room she knows is filled with birds. The result is [[spoiler: that she is nearly killed by dozens of attacking birds.]] When the actress asked, "Hitch, why would I do this?", he replied, "Because I tell you to."

** This is especially prevalent in Zombie's films when several people insult and even strike Myers. This wouldn't be so bad if it wasn't for the fact that Myers in those films is A SEVEN FOOT TALL GIANT!!!

* Pretty much ''any'' attempt the JSDF uses to stop/kill {{Godzilla}} falls under this. Most of the time, they only succeed in angering him...[[UnstoppableRage which only makes things worse.]] Conventional weaponry only annoys Godzila and giant robots and laser cannons only serve as a temporary solution before Godzilla gets back up again and lays waste to them. And, yet they still use them in each film.

** Orga from ''Godzilla 2000'' is a particularly infamous example. He tries to swallow Godzilla only to [[spoiler:be killed by Godzilla's Nuclear Pulse.]] Ok, how dense do you have to be to not realize that trying to eat the dinosaur with extremely powerful radiation-based abilities is a ''bad'' idea?

* ''IKnowWhatYouDidLastSummer''. Helen, a blonde, is running through back alleys. So close, so very close is a crowded parade. Back behind her is the killer, her dead sister and piles of tires. She hears a sound, ''stops'', turns back, the killer is there and grabs her and drags her behind the tires. Death ensues. Notable in that Helen is played by SarahMichelleGellar. ''After'' ''{{Series/Buffy|TheVampireSlayer}}'', which was specifically made to subvert the idea of the helpless blonde cheerleader. Good lord.

---> '''Sarah''': No, don't bet on it. Tyrannasaurs have the largest proportional olfactory cavity of any creature in the fossil record with the exception of one.

* Dr. Schneider from ''[[IndianaJones Indiana Jones and the Last Crusade]]'' who, after being told by the immortal knight that the Holy Grail must never cross the great seal, grabs the Holy Grail and starts backing away with it while Indy keeps telling her to ''don't move'' and ''don't cross the seal''!

* Many of the characters in ''Gorgo'' qualify. First, our heroes bring a dangerous animal into a major population center, then disregard the possibility of Gorgo being a juvenile, then disregard the effects of its [[MamaBear mother]] [[AttackOfTheFiftyFootWhatever coming into said population center]] (confident that [[FiveRoundsRapid modern technology]] can stop it) to the point where the government didn't even bother to evacuate the city! But the jewel in the crown has to go to a trio of teenage gawkers who got up close to the edge of the river Thames to watch the monster. They watched the army fill the river with gasoline, ignite it and watch the river burn for a full minute before realizing: Hey, maybe it's not such a good idea to be near the water while it holds burning gasoline. They are promptly, gloriously, incinerated.
** Commented upon in the MST3K episode by Crow.

* In ''{{The Dark Knight|Saga}}'', a guy is still driving towards the Joker at the end of the epic car chase sequence. Joker shoots up the car and the car crashes (the fate of the driver is not shown on screen). As pointed out on the movie's Rifftrax, "If you're still driving ''towards'' him at this point, you deserved that!"
** An employee figures out that Bruce Wayne must be Batman, and wants to blackmail him. Lampshaded by Morgan Freeman's character: "Let me get this straight. You think that one of your clients - one of the wealthiest, most powerful people in the world - is secretly a vigilante who spends his nights beating criminals to a pulp with his bare hands, and your plan is to ''blackmail'' this person?"
* ''{{Prince of Space}}'': "Your weapons have no effect on me!"

* The three victims in ''TheStrangers''; Kristen doesn't do anything but scream, trip and cry and actually '''injures herself''', James among other things decides to go get a radio ([[YouSuck because they were too stupid to have their cellphones on them]]) leaving Kristen alone and unprotected ''in the house, where their attackers can breeze in with ease'', and their friend has his windshield broken, sees destruction, mayhem and hears loud music playing (which to a normal person would scream '''DANGER''') and goes blithely in. ''Of course'' they all die.
* Anyone in the 2008 not-remake of ''PromNight'', especially Claire (Jessica Stroup) who sees the killer coming for her and ''just stands there'' and [[PoliceAreUseless the local police]], whose bumbling and ineptitude cause all the deaths in the movie.
* [[DamselScrappy Parker]] in the 2010 ''OpenWater'' knockoff ''Film/{{Frozen}}''. Granted, the guys weren't the brightest bulbs either (especially Dan, whose decision to bring the skiing-impaired, fair-haired maiden on ''a skiing vacation'' set the whole chain of events that led to them getting trapped on a skilift in motion - on his defense, though, it was at ''her'' insistence), but she takes it too far. [[spoiler: She is also the sole survivor of the flick due to a gigantic AssPull]].
* ''Every single human being'' in the ''Series/MysteryScienceTheater3000'' film ''TheCreepingTerror'' qualifies. The title monster eats people, but in order to do so it has to reach them by moving very slowly. However, because idiots simply sit there and scream rather than run away, they suffer the grisly death that their stupidity deserves. The fact that [[SpecialEffectsFailure they have to crawl into its mouth to be eaten]] doesn't help.

* Both ''[[Film/{{Hulk}} of]]'' ''Film/TheIncredibleHulk'' movies. Seriously, will General Ross ever get that shooting ? stopping Hulk, hurting Betty = Hulk turning into Banner? Bruce spends the entire movies trying to lay low and keep things under control. Then the military catches him, tries to perform experiments on him, he turns into the Hulk, and they make things WORSE by hitting him with heavy artillery, making him angrier than before.

* The military, law enforcement, and basically the government in general in the 2008 remake of ''{{The Day the Earth Stood Still}}'', though pretty much all of government in all of fiction is guilty of this trope, and it's not an entirely unexpected reaction to aliens being suddenly real. [[spoiler:Klaatu comes to Earth and reaches out his hand to the protagonists. Clearly, putting a bullet in him is the appropriate response. Only later do they realize he was able to shut down their defense network on a whim, and so they decide imprisoning and (implicitly) ''torturing'' him is a good idea. Klaatu's decision, after consulting a spy on Earth, is naturally that HumansAreBastards and have to go, so the swarm of nanobots beings devouring every man-made object in its path. The military bombs it to hell and back, only to see it grow larger. The Secretary of Defense at least grows a brain at this point, but the president orders even more bombing as if the opinion of his military adviser isn't worth considering.]]

* In ''{{Orphan}}'', the two kids never reveal that they've seen Esther committing violence, even though A) the mother clearly believes that she is and needs support and B) Esther keeps trying to kill '''them.'''

* ''[[{{Jaws}} Jaws: The Revenge]]''. The widow Brody is convinced that Jaws is still alive and going after her, so where does she go? Nebraska? Oklahoma? Some other place that's far away from the ocean? Nope: ''THE BAHAMAS.''

* TheStepfather remake has the main character's mother debunking all possible theories that her fiancé is a serial killer, from an old lady seeing his face on ''AmericasMostWanted'' to her sister telling her that the fiancé quit her company shortly after he was required to fill out certain information that might get him caught.

* Rose in ''{{Titanic}}''. From pretty much the moment the ship hits the iceberg, she has the IdiotBall superglued to her hand. Though Winslet's performance is a little vague, Jack's later dialogue ("When did you realize I [[spoiler: didn't steal the necklace?]]") seems to indicate she DOES believe Cal's frame job, however briefly. We're then given the impression she knows, from what Andrews told her for no discernible reason other than to set this up, that the lifeboats are totally inadequate and it's imperative to get off the ship before they're all gone. She then spends the rest of the sinking running around the boat, trying to save Jack, who convinces her to just GET IN THE GODDAMN BOAT ALREADY, jumps back out, runs DOWN in a sinking ship, and generally slows Jack down. Admittedly he and Cal play hackey-sack with a mini-IdiotBall throughout this (to the point you wonder what Cal has on him that the valet doesn't just say "Screw both of you" and get on the lifeboat offered) but Jack pretty much sums up Rose when he tells her "You're so stupid!"

** After the disaster, a U.S. Senate Inquiry discovered -to their shock- that procedures on the Titanic that they thought were negligent, were actually standard practice for the time. The big liners for all the major shipping lines tended to go full speed ahead at almost all times. (Blinding fog was pretty the only thing they'd slow down for). Maintaining the schedule was regarded as being paramount. As well, Captain Smith was not doing anything different than he'd done throughout his career. For decades, he operated ships in that manner and never had any sort of accident or serious incident. There was, realistically, no reason why he would think to do things differently now. And, as noted, all other captains did the same thing. As Senator Smith noted at the Inquiry, the state of shipping practices meant that a major disaster was BOUND to happen sooner or later. It was just Captain Smith's bad luck that it happened to him.
* The AnimalWrongsGroup at the beginning of 'Film/'TwentyEightDaysLater''. After being explicitly told that a monkey is infected with a contagious disease, one of them frees it anyway.

* Balian (Orlando Bloom) in ''KingdomOfHeaven''. [[spoiler:It makes more sense in context and is more like a case of lazy writing, but Balian's inaction is the prime reason behind the Big Battle of the film. His refusal, on many occasions, to kill a blatantly evil and dangerous character (a French Templar named Guy de Lusignan, played by Marton Czokas), is the prime reason behind the siege and the Big Battle of the film. Guy and his conspirators are the ones that provoke the war between Muslims and Christians, and their intentions are made clear (in-story, i.e. to other characters and not just to the audience) from the outset, and yet Balian doesn't make a move, and he refuses to do anything when his advisors/friends repeatedly express their concern. He doesn't come off as noble, more like an idiot and a passive character. Many characters die as a result of his course of action (or, rather, inaction), but he survives the film. In the film's epilogue with King Richard I he should probably say: "I'm the blacksmith, and the main reason you have to retake Jerusalem from Saladin, I'm the one that should be thrown in a dungeon full of Twilight merchandise." This film is not worth watching for this very story element]], it's a classic case of a story where if the main hero acted within common sense, there wouldn't be much of a story to be told.
* 2001 heist film Firetrap. A building is on fire. A guard is badly injured. What's a guy to do to save him? Get on the elevator during a fire, and talk a woman you like into going with you. What do you think happened to them?
* Several characters in both versions of ''DawnOfTheDead''. Since they're in the middle of a mass zombie outbreak, most of them die.

** Don't forget Chloe! She sits around in the dark, abandoned bathroom planning to spray Skye with a fire extinguisher. Can you say "GenreBlind"?

* Everybody in ''NightOfTheLivingDead''. Nobody in the film uses any sort of common sense, and it costs them their lives.

* The Prison Guard in ''ConAir.'' This Prison Guard and FBI Agent Larkin have just found a box labeled "Do Not Open" in the cell of Cyrus Grissom, a criminal genius, terrorist, murderer, and general all-around CompleteMonster. Larkin goes to fetch the bomb squad, explicitly ordering the guard to not open the box. Literally the second Larkin is out of the room, the guard sits right down on the bed and opens the box. [[StuffBlowingUp He is immediately blown to smithereens.]]
** It should also be noted that the other guard with him warns him that Larkin said not to touch anything. That's three seperate warnings the guy ignored. Truly TDTL!

* Whoever tries to domesticate [[{{Aliens}} xenomorphs]].

* Vincent Vega of ''PulpFiction''. A veteran hitman who really should have showed a little more respect for his weapons, he ended up causing the TropeNamer for IJustShotMarvinInTheFace due to recklessly pointing his weapon in the wrong damned direction, and when he was sent to whack Butch Coolidge for turning around and winning the fight he was paid to throw, he left his MAC-10 submachine gun on the counter while he went to the bathroom, not taking heed to the fact that his intended target might come across it while he was doing his business, leading to Vincent getting blown away.

* The two dumb kids in ''{{Jaws}}'', who decided that, while the town is on high alert for ANY potential shark fins, would do a prank involving a fake shark fin on a piece of wood, and tow it from underwater. Fortunately for the kids, they didn't get shot. Unfortunately, thanks to their distraction, at least one person was eaten and another kid was injured by the real shark, and managed to get away as a result.
** The shark himself, for [[spoiler:eating an explosive]].
* ''TheLastHouseOnTheLeft'': Aw, man, we raped and murdered these people's daughter, and they don't even know! Wow, now the mom is giving me a BJ! This is the best road trip ever!
* Every. character. in. ''CabinFever''.

* Each member of the ''MysteryTeam'', but especially Charlie and (later) [[spoiler: Jason]]. Jordy also qualifies.
* Coolio's character in ''Red Water'' escapes from an exploding boat with a trunk of cash by jumping into a river being prowled by a shark (don't ask why). Instead of ditching the money and swimming for land, he tugs it along. But that's not the worst. When the shark rises out of the water and bites the trunk, what does he do? Instead of swimming away, he ''tries to pull the trunk out of the shark's mouth'' until it breaks open, scattering the money all over the water. And of course, he ''tried to collect every bill in sight'', and is promptly eaten.
* A nameless Triad thug in ''HardBoiled'' shoots two SWAT officers in the climactic hospital battle, killing one of them. As he goes to finish off the other, Teresa Chang snatches up a pistol and holds it on him. Possibly believing that she was merely a trapped civilian (she was wearing plainclothes) and wouldn't have the nerve to shoot him, the thug slapped her and called her a "fucking bitch!" She promptly shot him about five times in the torso.
* David and Jack in the beginning of ''AnAmericanWerewolfInLondon'' exemplify this trope by, after being warned of danger, wandering off the road in the middle of the night, presumably without any food. Without the werewolf they still would have been lost for a long time. YourMileageMayVary on many of the other deaths, which could be explained as stupidity by panic.
* The title characters in YossiAndJagger. One could argue that the film works best as an hour-long PSA about Why You Do Not Have Affairs Within Your Chain Of Command.
* In ''{{Zoolander}}'', Derek Zoolander lost his friends in a tragic gasoline-fight accident. The only reason he survived is that he spotted his image on the front of a newspaper and went over to look at it.

* Invoked in the slasher spoof ''ShriekIfYouKnowWhatIDidLastFridayTheThirteenth''. Everyone agrees that with the recent killings they should hide out at a safe place – but they all think it should be in the middle of nowhere, preferably the dark woods in the pouring rain, and without any adult supervision or police protection in the near vicinity. One even suggests that they should go to a deserted place that's been abandoned ever since a bunch of dorky kids were dismembered there.

* Arguably Kalle from {{Troll Hunter}}, who concealed the fact he was a Christian from the crew and the hunter despite the hunter warning them that Trolls will go after anyone with Christian blood. It would have been justified since he didn't initially believe it to be a life or death decision when mythological creatures were involved, EXCEPT for the fact that both he and the crew had two violent encounters with trolls before finding themselves trapped in a cave filled with Mountain King Trolls that led to him getting killed.

* Makes the perfect couple with {{Bond Villain Stupidity}} in ''{{A History of Violence}}'', where all the mobsters, including their boss, dies horribly by the hand of the protagonist due to their inability to just kill him off at the first occasion. The result is particularly hilarious when we learn, just before the last shooting, [[spoiler:that in spite of all the talking and the stalking the villains performed earlier, their intentions was REALLY and JUST and PLAINLY to see the protagonist DEAD]]. Bonus points for the fact that they even know he was the ultimate {{Badass}} from the very start.
* A variation (arguably) in ''TheVanishing''--Rex Hofman isn't too ''dumb'' to live, per se, as much as he is too ''obsessed'' to live. After spending years trying to discover the truth behind his girlfriend's mysterious disappearance in a crowded public place, he finally tracks down Raymond Lemorne, the man behind it. But if he kills Lemorne, he'll never find out what happened; his girlfriend may even still be alive, for all Rex knows. And he can't involve the police because there's no evidence against him. The only way he can ever find out what happened to his girlfriend, the all-consuming question he's been trying to answer for years, is to take a drug-laced cup of coffee that Lemorne offers him. [[spoiler: He does. And [[HighOctaneNightmareFuel wakes up]] [[FateWorseThanDeath in a coffin]], [[BuriedAlive the sound of dirt thudding on the lid above him]].
* '''EVERY SINGLE CHARACTER''' in ''Splice''. Their so friggen stupid that when they all get killed or even raped by the monster, it's hard not feel as if they had it coming. When your characters are so stupid that you don't feel bad that they're getting raped and murdered by a horrible genetic monstrosity, something is obviously wrong.
* Many of the traps in ''Saw II'' required the participants to be terminally stupid in order to kill them. Most of them are therefore effective.

* Jesse from the second ''AlienVsPredator'' movie. Her companions already killed the Alien in the stairwell, but she runs away and screams, forcing her companions to chase after her through a more heavily Alien-populated section of the hospital. Then she dies when she gets into the path of the Predator's disc blades. The Predator wasan't even ''trying'' to kill her, she just runs striaght into the middle of a fight between the Predator and Aliens and gets hit ''by accident''. WhatAnIdiot.

* In the opening sequence of ''Film/IronMan'', Tony Stark is riding in a Humvee that is ambushed. The crew immediately identifies that the attack is coming from the ''left.'' The driver immediately jumps out ''on the left side'' and gets shot. The rear left passenger sees the driver die, and then ''does the exact same thing.''
** Note that this is exactly what they are supposed to do. Since the ambushers are firing antitank weapons and armor piercing small arms, the soldiers have much better chances dismounting and finding cover outside of the vehicle than they would have staying in a stationary bullet magnet where they can't shoot back.
** Dismounting might be the right thing to do, but dismounting out of the side of the vehicle that all of the incoming fire is hitting?
*** When the doors on the other side won't open due to the hit your Humvee just took? Not much of a choice.

* Makes the perfect couple with {{Bond Villain Stupidity}} in ''{{A History of Violence}}'', where all the mobsters, including their boss, dies horribly by the hand of the protagonist due to their inability to just kill him off at the first occasion. The result is particularly hilarious when we learn, just before the last shooting, [[spoiler:that in spite of all the talking and the stalking the villains performed earlier, their intentions was REALLY and JUST and PLAINLY to see the protagonist DEAD.]] Bonus point for the fact that they even know he was the ultimate {{Badass}} from the very start.

* Very much Frank of ''State of Grace''. A mafia boss who goes to extreme lengths to [[spoiler:kill his own friends and relatives]] just to satisfy the requests of another gang, against which he fears to lose in case of a mob war.

* The central character Annie in the 2010 film ''Trust''. At the age of 14, she starts chatting online with someone called Charlie whose admitted age over the course of the chats goes up from 16 to 20, then to 25, and when she meets him in person at a mall we see he has to be in his late thirties at least. And what does she do? Instead of walking away, she gets into a car with him. And then goes to a motel room with him. And models in red underwear for him before he rapes her (she doesn't put up a struggle at that point because she's convinced herself that he really cares about her, unaware that their supposedly romantic encounter is being filmed). All this seems to occur in a universe where a 14 year old girl with caring and involved parents has not heard terrible stories of what can happen if you get into a car with a stranger you met on the internet.

** When last seen, the next-to-last survivor of the platoon is just getting disintegrated, [[BeyondTheImpossible while the last survivor is radioing for more reinforcements to come pick up the grenade]].

* In ''Film/DantesPeak'', the grandmother decides not to leave the area of the erupting volcano, prompting most of the other characters to go after her. Later, she attempts to wade through acid, which does kill her.
** Not leaving wasn't her being too dumb to live, it was just her being stubborn even though she knew she would likely perish. The problem she failed to foresee was the kids trying to retrieve her, and once they went Rachel and Harry had to go after them. Wading through acid was also not being too dumb to live, it was an outright [[HeroicSacrifice choice]] to save the rest of the people in the rapidly-dissolving boat.

** The US military in ''Film/TwentyEightWeeksLater''. They allow unsupervised access to an asymptomatic infected, who consequently infects someone. [[spoiler:Then they evacuate another one to Europe where the whole thing starts all over again.]]

*** "Having a fun time" was actually helping the diplomacy along a bit. For one, Dr. Augustine was allowed back into the village (she had been presumably banished after the school shootout).

* [[DamselScrappy Parker]] in the 2010 ''OpenWater'' knockoff ''{{Frozen}}''. Granted, the guys weren't the brightest bulbs either (especially Dan, whose decision to bring the skiing-impaired, fair-haired maiden on ''a skiing vacation'' set the whole chain of events that led to them getting trapped on a skilift in motion - on his defense, though, it was at ''her'' insistence), but she takes it too far. [[spoiler: She is also the sole survivor of the flick due to a gigantic AssPull]].

* [[spoiler: [[DrillSergeantNasty Hartman]] ]] from ''FullMetalJacket''. When [[spoiler:Pyle]] is in the middle of a nervous breakdown and holding a rifle, he decides that, rather than call the MPs, he should insult the poor guy. It doesn't end well for him

* Arguably Kalle from {{Troll Hunter}}, who concealed the fact he was a Christian from the crew and the hunter despite the hunter warning them that Trolls will go after anyone with Christian blood. It would have been justified since he didn't initially believe it to be a life or death decision when mythological creatures were involved, EXCEPT for the fact that both he and the crew had two violent encounters with trolls before finding themselves trapped in a cave filled with Mountain King Trolls that led to him getting killed.
