Dr. Gediman in Alien: Resurrection. At first it's stupidity, then it becomes outright craziness. He stands in front of an alien and bares his teeth to the thingnote For those that do not know, this is a primary sign of showing aggression among most species., which then tries to pierce his skull with its second mouth. He only survives due to the reinforced glass between them. He inspects the aliens' escape without backup, and gets captured by them. When the Newborn is born he outright tells it to come to him, and it finally kills him. He stands out because no other character in the entire series is this stupidly asking to get killed. Of course, the man is a Mad Scientist played by Brad Dourif, and his sanity is highly questionable.
Jesse from Alien vs. Predator: Requiem. 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 wasn't even trying to kill her, she just runs straight into the middle of a fight between the Predator and Aliens and gets hit by accident. What an Idiot.
There's also the part near the beginning when the pizza delivery boy and his brother go down into the sewer for his car keys at night and nearly get killed by the Predator. It wasn't even like it turned to night by the time they got to the sewer, they clearly waited until night to go down, presumably so no one saw them doing it. Granted they didn't know that the Alien or Predator were on Earth yet, but still one would think that going into a sewer at night is just asking for some sort of trouble.
Also none of the characters seem capable of realizing that the Predator is fighting the Aliens and that maybe it would be a good idea to just let it go about it's business and not bug it. The main character seems to at least partially notice this near the end, choosing to flee and leave the Predator alone rather then trying to fight it (an action that gets some other characters killed).
Any human who tries to capture/breed/weaponize/domesticate the Xenomorphs falls under this. The (non-canon) Aliens comics explain this as an telepathic influence from the hive mind—they pull at the weak points of humanity and guide them into making breeding easier. It becomes closer to "Too Greedy To Live" in this light.
Come to think of it, the Predators in many Alien vs. Predator media often fall into this trope. Despite the fact that Xenomorphs are apparently one of the species that Predators enjoy hunting the most, and thus should already know what they're capable of, Predators are frequently Too Dumb to Live when they fight them. For instance, instead of attacking them at range, they frequently meet them in hand to hand combat, which is the Xenomorph's forte. Worse, they often tend to attack them not with blunt weapons or lasers, or even just their own fists, but with bladed weapons. That's right, they use bladed weapons in melee combat on a species that usually kills its prey at close range and bleeds acid when it gets cut. Even the so called "veteran warriors" do this. However, Expanded Universe gives a possible explanation for this; Predator blood neutralizes Xenomorph acid, so the acid isn't nearly as dangerous to them as it is to other species and the veteran Predators utilize specially crafted blades that don't melt on contact with the acid.
It's also very important to note that Predator culture is heavily themed around stuff along the lines of "the honor of the kill". Using ranged weapons is considered a less honorable kill than going after a worthy opponent, using blades. One only has to look at the end of the original Predator movie to see this. The Predator removes all weapons bar its blades. Of course, it then looses so maybe they really are just too dumb to live.
David and Jack in the beginning of An American Werewolf in London 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.
Dr. Atherton in Arachnophobia. He's the foremost spider expert in the country, and he's been extensively informed how dangerous the new breed of spiders are. He sees no problem however in investigating the huge spider's nest in the barn all by himself, with no protection whatsoever. Predictably, he dies within minutes.
Granted, he didn't expect the General to be up there, and the General already had a grudge against him for killing its mate in the forest...
Never mind the fact that he expected whatever was up there to come crawling down the web as opposed to swinging up in his face.
Half of Gotham seems to be this way. It was already common knowledge that the Joker had murdered many people, but that didn't stop them from diving at the cash he offered in public. He even said into a microphone, "Now comes the part where I relieve you, the little people, of the burden of your failed and useless lives," but they're too engrossed to listen. A minute later, many are dead. And some who aren't dead yet still grab for cash.
A plot point cut for length in the movie but present in the novelization, you'd think that the people grabbing the money would have noticed the Joker's face on each bill and realized the cash was all fake.
Also, poor Bob, after Joker has just been decisively pissed off and now wants to blow off some steam. He's had his little outburst, but there's a Tranquil Fury brewing under his crackpot exterior — something his loyal lackey fails to notice.
Joker: Bob? Gun.
Bob:(unquestioningly hands his boss his gun, not realizing Joker's in a killing mood; Joker coldly pops a bullet in his chest)
Batman Returns gives us The Ice Princess who is shown to be a ditz when she can't remember whether the lights come on and then pushes the switch or vice versa, but the real crown jewel is when she stands on the edge of a building; it's no wonder The Penguin so easily got Batman framed.
She wasn't there by choice — Catwoman took her up there to have a "girl talk" and probably let her go like that in order to set up Penguin's frame. Batman definitely didn't help things by telling her "don't move" immediately before Penguin showed up with the umbrella full of bats.
Quite a few characters in the film adaptation of Battle Royale. Toshinori Oda probably takes the cake for surviving a burst of gunfire due to his bulletproof vest, then jumping up a few seconds later and loudly proclaiming "I'm alive!"
Alfred Hitchcock's The Birds has Melanie going up to a room she knows is filled with birds. The result is 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."
Blade Runner. Tyrell, Tyrell, Tyrell. When your angry, vengeful creation is confronting you and demanding you perform a medical procedure on him, the correct answer is not to explain why that procedure would be fatal, it's to perform it anyway. Possibly justified in that his idolization of Roy as his ultimate creation may have been stronger than his self-preservation.
In the English cop movie Blitz, there is a particularly simple individual by the name of Radnor who fancies himself as a police informant after realizing that a guy who boasts of shooting a police dog 'for practice' is now killing police officers. Lacking the evidence needed to convince the police, he starts his own investigation. His idea of inconspicuous clothing while observing the killer's residence amounts to a purple, green & white jump suit. When he discovers the car in which the killer is hiding weapons & trophies, he breaks into it and personally handles the murder weapon before putting it back. The police aren't interested in his evidence (not at the 50,000 pound asking price) so he goes to a member of the press who is not much smarter. When he shows the journalist the car, the killer observes them. They retire to a pub to 'talk business' & when the journalist produces the 50 grand in an envelope, Radnor insists it is not 50 grand, and goes into the toilets to count it. Guess who followed them to the pub? Radnor is in the toilets counting, when the killer breezes past him, perhaps to check the latter stalls for potential witnesses. Does he take this opportunity to run for the door or scream for help? No, he just becomes terrified and starts pleading with the killer that "I haven't told him your name yet". He meets his end in a toilet bowel.
Particularly glaring about this part is that they're in a public pub that has at least a dozen people in it at the time. Added to this is the simple fact that the killer is not some huge, muscular badass, and the door to the witness-filled pub is only a dozen steps away and definitely not soundproof. If Radnor had done anything besides be reduced to a whimpering simp by a man who weighs less than he does, he would have been able to alert everyone else and might have not only survived but caught the killer and been a hero.
The killer has his own TDTL moment at the end of the film. Trying to kill the officer leading the investigation, he follows him to a parking station while wearing a police uniform he stole from one of his victims, but instead he is ambushed by the officer and his 'buddy' cop. He gets a thorough beating then laughingly claims he is going to sue them for all they are worth. Then one officer points out they have in their possession his gun, which has previously been used to shoot at people in uniform. Guess what happens?
The Boogens features a cast of this. The titular monsters may actually be smarter than the humans and dog, and they're not actually depicted as anything other than hungry. Sadly, probably the stupidest of the humans are the alpha couple, and thus survive.
In Born Of Earth, a character decides to stray away from the main group to take a piss...while being in the sewers being chased by monsters and one of their party having been gruesomely killed only barely a minute before.
Multiple characters in Burn After Reading more than qualify, but Chad Feldheimer goes above and beyond the call of duty, and definitely earns the title since he ends up getting shot in the head before the second act is even over.
I'd honestly like to take a poll of women to see how many would continue shaving their legs if the skin started to slough off with noticeable amounts of blood and scraping noises to Squick anybody out.
Or a poll of people in general to ask if they would have unprotected casual sex in the middle of a deadly epidemic.
Let us take a moment to mourn for the intelligence of the driver in The Call who made not one, not two, but three really stupid mistakes that ended in his death. #1, he followed someone who was acting suspiciously to a secluded area. #2, he pulled out his cell phone to call the cops right in front of him. #3, after he's put in the trunk, he inexplicably starts screaming and yelling for help, despite Casey begging him not to. That last one ends with him getting stabbed repeatedly in the chest with a screwdriver.
Head goon Buddy in Christine, when chased by the possessed big V-8 powered car, opts to run down a long stretch of straight highway, rather than get off-road where a car might have some difficulty getting through at any speed.
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, another character loses her life to save him from the parasites while his hands are full, and 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 Nicknames for the monster is "Darwin".
Clive in Cold Storage.
The Prison Guard in Con Air. 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, and murderer. Larkin goes to fetch the bomb squad, explicitly ordering the guard to not open the box. The second Larkin is out of the room, the guard sits right down on the bed and opens the box. He is immediately blown to smithereens.
The other guard with him warns him that Larkin said not to touch anything. That's three separate warnings the guy ignored. Truly TDTL!
One segment of the horror anthology Creepshow details the sad demise of numbskulled backswood hick Jordy Verill.
Hundreds of people are sheltering in the public library, and decide that rather than listening to the son of the smartest climatologist in the country (who just had an extended conversation with his father), they're going to go and do the exact opposite. They all freeze to death. Had they bothered listening, they would've been uncomfortable, but they would've survived.
Subverted and played straight with those who do stay in the library and decide to burn books to keep warm, which are stacked on wooden shelves. One could argue that they simply could had burned the shelves themselves, but considering that wooden shelves would then have to be broken up to fit in most fireplaces and are usually painted/stained with substances that release toxic fumes when burned, burning books were the safer alternative by far. The dumb part was tearing the books apart and burning them page by page rather than using some loose pages as firestarters and then burn entire books-that would have been much more effective.
Then there was the scene meant to be a Crowning Moment of Heartwarming in which Frank is dangling from a glass roof. The glass starts to crack and Frank decides to make a Heroic Sacrifice because there is no way the glass can support Jason and his weight. Fridge Logic sets in when you realize Jason is holding onto two steel support beams that could have easily held the weight of the sled, the entire party, and probably an elephant.
And then there's the entire trip. The very intelligent climatologist, who said that survival outside would be impossible, discovered that the storm would last a couple days and personally recommended the president send search and rescue parties once the storm ended, loses his best friend and almost kills another doing exactly what he said not to do and arriving at the same time as the rescue teams he is responsible for sending.
The military, law enforcement, and the government in general in The Day the Earth Stood Still (2008), though all of government in all of fiction is guilty of this trope, and it's not an unexpected reaction to aliens being suddenly real. 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 Humans Are the Real Monsters and have to go, so the swarm of nanobots beings devouring every man-made object in its path. The military bombs it, 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.
Klatuu's people deserve extra stupidity points as well. Consider that their entire motivation for destroying humanity is to preserve the non-human portions of Earth's biosphere. They then set their nanotech-based weapon on "Dissolve Everything", including rocks and trees! In the immortal words of Robert Asprin, "Very inferior as superior beings go."
The location of the facility implies this form of mentality in the project designers. Genetically-enhanced super-sharks with improved brain functions? Why not build the research lab for them in the middle of the ocean where nobody can reach the personnel and where, if the overly-sophisticated defense system breaks down, said sharks can escape into the wild and spread their super-genes around the world. As Cracked.com put it, "You know what makes a really effective defense against sharks escaping? Hundreds of miles of dry land."
The sheer dumbness of giving something as deadly as a shark increased human brain power in the first place. That was bound to go well. Especially without sterilizing them.
Deep Impact. Sarah's parents. They let their child refuse to go into the ark tunnel and then when Leo comes back for her, they don't try to follow on foot just because he has a motorbike.
Raymond Cocteau in Demolition Man frees a dangerous psychopath in order to get rid of an enemy, but he has it implanted in his brain that he can't ever harm him. However, he also allows him to bring other criminals inside his home who don't have the don't-harm-Cocteau rule implanted. It doesn't end well for him.
Elysium: Delacourt for upclose confronting a complete psycho like Kruger without any protection or guards.
Katya in Europa Report staying out in deadly radiation long after advised to come back with some unknown danger below the ice.
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?
Davis in the 2004 remake of The Flight of the Phoenix; the plane has just crashed in the middle of the desert and it's stormy outside. He goes out, in the middle of the night, to take a leak. Not only does he walk unnecessarily far away from the plane (It's the middle of the night! No one will see you, jeez), he somehow trips and falls down, then rolls ten meters away from where he was — and gets lost. He fails to find his way back to the plane, and dies out there.
Freddy vs. Jason. When Freeburg sees a monster bug show up, he thinks it's awesome when it takes out a bong, and decides to follow it when it goes away. This might be explained by the fact that he's stoned out of his mind, but getting high in the first place while knowing that they're on the run from two undead serial killers was his own decision as well, so he still qualifies.
Although this trope is hardly rare in slasher movies, special mention must be given to the Final Girl from the original Friday the 13th (1980). She omitted no less than three times, each time leaving the killer's weapon right there for them when they woke up. There were a bunch of other examples of her stupidity, but that was the outstanding one.
The worst part is that if the girl HAD finished off Pamela any of those other times, she probably would have lived a long life. The only reason she's killed in the next movie is because Jason witnessed her killing Pamela, which he probably wouldn't have if she had killed Pamela before she finally did. Not only that, but since we never get any evidence that Jason killed anyone before Part 2, this might have even been what drove Jason over the edge.
Parker in the 2010 Open Water 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 ski-lift in motion - on his defense, though, it was at her insistence), but she takes it too far. She is also the sole survivor of the flick due to a gigantic Ass Pull.
Hartman from Full Metal Jacket. When 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.
On top of that, Private Joker had warned Hartman mere moments before that he suspected Pyle was Section 8.
The archangel Gabriel from the movie Gabriel qualifies. From the very first person that he meets onward he is constantly warned that using his powers will attract the attention of every bad guy in the city, letting them know exactly where he is. So what does he do? Why, he seeks out his fallen comrades who are in hiding and proceeds to use large quantities of his powers to "help" them, even when they specifically and emphatically tell him not to and yell at him for it after the fact.
To top it all off, Gabriel is actually shocked and suffers a Heroic BSOD when he learns that he DID, in fact, lead the bad guys to his comrades and they all died because of his stupidity. Asmodeus even points out, "If you didn't want them dead, why did you lead us to them?"
First mate Greer in Ghost Ship knows he is on a ghost ship where some of his mates have already died. After downing his sorrows with a drink, he decides to shut off his brain and try to make out with the seductive female ghost. He falls straight through her intangible body into an elevator shaft.
The fatal flaw of the Neo-Vipers from G.I. Joe: The Rise of Cobra. The loss of their self-preservation instincts might make them determined, but it also makes them much more likely to make fatal mistakes.
Any attempt the JSDF uses to stop/kill Godzilla falls under this. Most of the time, they only succeed in angering him...which only makes things worse. Conventional weaponry only annoys Godzilla 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.
The aliens in the Showa era don't seem to fair much better. You'd think they'd learn by now that Ghidorah is just going to be defeated by Godzilla (and whoever Godzilla is teamed-up with at the time). Yet, they don't.
Orga from Godzilla 2000 is a particularly infamous example. He tries to swallow Godzilla only to 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?
Pretty much anyone trying to harm Godzilla's son in any timeline is proof that they're pretty much going to have to consider it a miracle if Godzilla leaves anything left of them after he gets done with them. Whether or not whatever's left is living, or for that matter even recognizable in any way, shape, or form is another matter altogether. Trying to harm any iteration of Godzilla's son is a pretty good way to commit Suicide by Godzilla.
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 mothercoming into said population center (confident that 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 and ignite it, then 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.
Crow: (laughing) Oh, now that just seemed completely avoidable.
At one point in a screening of Halloween (1978), Laurie Strode's stupidity is too much for one audience member. When she fails to make sure Mike Meyers was dead after he came back from apparent death the first time, the audience member shouts, "You stupid bitch, you deserve to die!"
Also, she never thought to maybe pick up the knife that Meyers dropped after being killed the second time so that if he did get up she could defend herself.
Her friends that do get killed are even worse.
Michael's an indestructibledemon in human form. Laurie didn't know this when she stabbed him in the throat with a knitting needle, and later in the chest with his own knife. As for her friends, Michael's good at staying hidden. They never knew they were in danger in the first place.
On the one hand, he had been pretty docile for about seventeen years, not making a sound or causing anyone any trouble. On the other hand, he was in the hospital for committing multiple brutal murders, and killed one of the hospital staff for insulting him. Best not to provoke him.
All the criminals, and arguably most of the citizens. The titular superhero Hancock is a Jerk AssFlying Brick who can and will use his powers to frighten, humiliate, or possibly mutilate anyone who remotely displeases him. He's also immune to harm. Despite this everyone save Ray, the main character and the only one with any common sense either insult him, try to provoke him, or shoot him; despite the fact it should be obvious he will cause them serious harm in return.
The (former) prisoners who assault Hancock at the hospital. Sure he can be hurt now because he's turning mortal. But he still has Super Strength. And there is no way they could have known he'd be vulnerable.
The scene before showed a news report about him being hospitalized with gunshot wounds. Though they did start planning to escape and get revenge long before this happens though.
Almost every character in The Happening. You would think that an airborne toxin of unknown origins, before it was revealed to be plants, would be a sign for the people to stay at home, closing all doors and windows and never go outside at risk to be infected and suicide themselves. But no. All they do is BE OUTSIDE IN HIGH RISK AREAS AND BE SURPRISED WHEN PEOPLE ARE DYING!!! Plus the brilliant idea to "Run away from the wind".
Mark Wahlberg's character (a High School Science teacher) telling a woman over the phone to stay indoors and not go near the large tree outside her window. He does this while standing in an open field.
The whole movie revolves around plants making people Too Dumb To Live. The toxin retards people's self-preservation instinct, which rather than making them heedless of danger, makes them all decide to commit suicide in the most gruesome way at hand.
A nameless Triad thug in Hard Boiled 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.
Both ofThe Incredible Hulk 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.
In the second film, Ross specifically tries to knock Bruce out with gas instead of making him angry, and orders his men not to engage. If Bruce hadn't seen Betty there being kept away from him, it might've worked. Nice job breaking it, Betty!
Emil Blonsky deserves special mention. He held his own in a battle with Hulk, mainly because of how quick he was, due to the super soldier serum he'd been given. After he and the rest of his military division have thrown everything they have at Hulk, and he is still walking, Ross tells Blonsky to fall back. Blonsky then rips off his earpiece, drops his gun and attempts to stare down the Hulk, saying "Is that all you've got?" Cue Hulk-powered thrust kick to the chest, followed by being smooshed all over a tree. Said smooshing breaks every bone in his body, which would have killed him if not for the super soldier serum.
Katniss, safely hidden in a tree, watches a Tribute learn a cardinal rule about stealth in hostile territory the hard way: under no circumstances do you make a camp fire: you'll be too easy for the enemy to spot.
Clove, rather than just killing Katniss, starts gloating about how her group killed Rue. Thresh happens to be listening, and it ends badly for Clove.
I Know What You Did Last Summer. Helen, a blonde, is running through back alleys. So close, so very close is a crowded parade—which she left in order to enter said back alleys. 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 Sarah Michelle Gellar. AfterBuffy, which was specifically made to subvert the idea of the helpless blonde cheerleader. Good lord.
Even before that, she distracted the police officer who was trying to protect her right as he approached the killer. This led to both the police officer getting killed and the killer becoming aware of her presence.
Dr. Elsa Schneider from 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! Moments later, she finds herself hanging for dear life above a huge chasm that she caused. Instead of letting Indy save her, she reaches for the grail. Naturally, she suffers a Death by Materialism when her hand slips from Indy's hold.
Donovan also qualifies. After being told that "while the true grail brings life, the false grail will take it from you", he pauses, not knowing which one to pick. When he lets Dr. Schneider choose for him, he simply assumes it must be the one. Should have asked for another volunteer.
This is more an example of Distracted By The Shiny, because Dr. Donovan was obviously overwhelmed by the moment, thinking he was holding the legendary Grail in his hands.
In Ink, during the kidnapping scene, it never occurs to Emma to try hiding under a bed or a couch until the nasty monster that's trying to take her gets run off. Similarly, it never occurs to any of the Storytellers to grab Emma and get her away from Ink, or to call in reinforcements before Ink even made it out of the house.
Josh Dalton from Insidious definitely qualifies. Not only does he spend most of the movie as the Agent Scully, arguing with his Genre Savvy wife, when he finally does accept the weirdness and go into the Further to save his son, he breaks every rule he was told to follow, culminating in him stopping ten feet from his body to yell at a ghost that's been stalking him since childhood to possess him specifically. The ghost possesses his body, resulting in the deaths of his family and every other character in the film. And Josh is likely stuck with a Fate Worse than Death. Nice Job Breaking It, Hero.
Even after the sadistic Japanese Colonel Sato watches Ip Man beat ten karateka nearly to death, he doesn't think that walking within close range of the Wing Chun master and threatening his wife and child with a gun is a bad idea.
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 eating an explosive.
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.
The first victim in Jaws 3D, who breaks the number one rule of diving—never dive alone—when he goes to repair a malfunctioning sea gate. Even if there wasn't a huge shark out there waiting for him, any number of things could have happened to him with no one to save him or call for help.
Darry from Jeepers Creepers. After seeing what appears to be a strange man dumping bodies down a shaft, he insists on making his sister turn their car around and going back by themselves to investigate (instead of simply reporting the matter to the police), even going as far to venture down into the shaft himself. His subsequent involvement costs him dearly down the line....
From Judge Dredd, the rookie Street Judge that dies in the beginning. Isn't one part of police training to not run off alone into an unsecured building? In his first attempt to run blindly into combat, he actually cites a training exercise at the academy as giving him grounds to do so, before Hershey admonishes, "This is NOT a training exercise."
Many, many, many characters in the Jurassic Park series. Especially in Jurassic Park III, when Amanda is shouting into a megaphone. Towards a forest. On an island she knows is filled with dinosaurs.
That's not even half of it:
Amanda:(on the megaphone) ERRR-IIIC! Dr. Grant: And tell your wife to stop making so much noise! We're food to these damn animals. Paul:(yelling) AMANDA, HONEY! DR. GRANT SAYS IT'S A BAD IDEA! Amanda:(on the megaphone) WHAT? Paul:(pointing broadly at Alan) HE SAYS IT'S A BAD IDEA! Amanda:(on the megaphone) WHAT'S A BAD IDEA? (a roar is suddenly heard)
The Lost World: Jurassic Park, with the supposed biologist Sarah Harding being one of the worst. She goes alone on an island filled with dinosaurs, and complains that Ian doesn't need to rescue her, then stumbles from one moment of rampaging stupidity to the next like a female Mr. Bean. To make matters worse, she lectures everyone with her about what you should or shouldn't do in a situation before immediately going out and doing what she said NOT to do. And unfortunately, this is a situation where her being Too Dumb to Live results in not her death, but the deaths of nearly EVERYONE she encounters on the island.
Burke: No, no. You're wrong there, Dr. Harding. We'll lose them once we leave their territory.
Sarah: No, don't bet on it. Tyrannosaurs have the largest proportional olfactory cavity of any creature in the fossil record with the exception of one.
So naturally, she continues to wear a vest covered in the blood of the aforementioned tyrannosaurs' infant. It's not like she forgot that it was there—Roland pointed the blood out to her and she explained that it was the t-rex infant's, and didn't think that there might be some danger in carrying it around.
Balian's brother from Kingdom of Heaven who really rather brings his death upon himself when he mocks his brothers grief, over Balian's dead wife, while wearing the pendant he stole from her body.
Kingdom of the Spiders is about a town overrun by extremely venomous tarantulas. Apparently all the townspeople are wearing brand new shoes they don't want to mess up, because at no point does anyone just try stepping on them. One character tries to shoot two dozen of them with a revolver and no extra ammunition in sight; when she sees a spider on her hand, she shoots it, and three fingers, right off.
At one point the hero is holed up in a cabin with a handful of other people. They discover spiders coming in through the vents and take care of it quickly by blocking them. A few scenes later, everyone's feeling hot and the hero opens the vents to check on the air conditioning, leading to the death of one of his companions.
The 1985 film version of King Solomon's Mines has a henchman who is given the following choice: either run for his life or climb out the window to retrieve the stick of dynamite Quartermain just threw out the window. You guessed it. He goes after the dynamite. To his credit, he does manage to retrieve the dynamite just before it explodes. His last words: "I've got it!"
The Northern Water Tribe counts as this in The Last Airbender, since the firebenders need torches to bend fire, Pakku suggests extinguishing all of them to render them powerless and... they never actually do that.
That one was almost justified; with the time constraints of the movie, they couldn't go through all the steps that brought the Gaang out to an oil platform, so the earthbenders had to be held on solid ground. It was implied that, somehow, the Fire Nation soldiers had completely broken their will to fight back before they were imprisoned. Good so far. If the Rousing Speech had been about fighting for your families and homeland and giving them the WILL to fight, that would have completely averted this trope; but instead, Aang all but says, "What are you idiots doing? You're standing on 16 trillion tons of the one weapon you have!"
Aw, man, they raped and murdered these people's daughter, and they don't even know! Wow, now the mom is giving that guy a BJ! This is the best road trip ever!
Still not as dumb as the girls, who had their hands tied IN FRONT of them didn't think to pull off the gags and use their teeth to remove the ropes
In Lethal Weapon 2, the bad guy who is responsible for killing Riggs's girlfriend and a bunch of their cop buddies is involved in a major shootout. He's a South African diplomat, so when they have him dead to rights, he pulls out his passport and intones, smugly, "Diplomatic immunity!" He gets shot in the head for his trouble by Roger Murtagh, who delivers the immortal line, "It's just been revoked."
And to lay the icing on the Too Dumb to Live cake, just before saying this line, the bad guy in question had just gunned Riggs down, which anyone watching a buddy cop picture knows is going to get you killed no matter which half of the law-abiding / loose-cannon partnership it's done to.
Diplomatic immunity does not protect you when you're openly committing crime and your guilt is obvious. If nothing else, your country will revoke it in a heartbeat because they don't want to be associated with your crimes.
Even moreso, diplomatic immunity means immunity from prosecution, not harm. He had just shot a police officer and was still brandishing the gun at another police officer, who would not have to worry about diplomatic immunity since he'd be excused for shooting the guy due to self-defense concerns.
Almost everyone in The Mist. They all hold the Idiot Ball so often that it's difficult to believe that they survived the first few minutes of the film. But the best example has to be when the survivors decide to take Mrs. Carmody's advice and use Human Sacrifice as a way to appease God and the creatures in the mist. As anyone who understands basic animal behavior will tell you, that kind of stuff will only draw more monsters to the immediate area around the store. Predators swarm at the smell of blood or the chance for an easy meal, so sacrificing people was actually the stupidest thing they could've done. On top of that the mist creatures seem to hunt by sense of smell or hearing because of low visibility, so attracting them to the store with an easy, injured meal would've also alerted them to the people hiding inside of it.
They don't believe the mist creatures are animals, they believe that they are wrathful abominations sent by a furious God, despite testimony to the contrary. If they had accepted that Carmody was right, and that God needed to be appeased, then Human Sacrifice could well have been what was needed. The real Too Dumb to Live moment was letting themselves be convinced by her anyway, especially as they somehow think that "secret military project trying to unlock alternate dimensions" was somehow less plausible as a source of the trouble than "vengeful act of an uncharacteristically unpleasant Abrahamic God," especially as the source for the first possibility was "soldier who worked on said project" and the source of the second possibility was "nutcase."
Subverted by the Mama Bear mother who leaves the store to search for her young children. She appears to be the absolute dumbest among them; but instead she ends up surviving, perhaps as a karmic reward for her misguided calling-out of the other townsfolk for their understandable refusal to walk out into the mist with her to accompany her to her house and children.
The science fiction spoof Mom and Dad Save the World has a memorably absurd case of this on a massive scale, played for laughs: There's a weapon called the light grenade that disintegrates anyone it comes in contact with once the pin is pulled, but only if the victim is dumb enough to actually pick it up. It has the phrase "PICK ME UP" engraved on it. Because the movie takes place on a planet full of idiots, one of these left out in the open takes out a platoon of evil troops, each one picking it up immediately after seeing what just happened to the last guy who did that.
When last seen, the next-to-last survivor of the platoon is just getting disintegrated, while the last survivor is radioing for more reinforcements to come pick up the grenade.
Still worse is the Light Grenade is commandeered technology, so the troops all know exactly what it is and what it does, and lampshade this with such lines as, "The Earth Man has a light grenade for a head" then when everyone asks what they pick it up, or "Everyone be careful, there is a light grenade on the ground." then responding to "Where" they pick it up and say, "Right Here" before poofing into a flash of light with a moment of sudden realization on their faces.
The irony of this is King Raff, the smartest of the people on the planet, who admits even he himself is an idiot, somehow invented almost all the technology on the planet, including the Light Grenade, a device that is infinitely reusable, and leaves seemingly no waste, just lots of piles of perfectly clean clothes, as well as a beam that can pull a car and safely transport it and its occupants through space from Earth to his planet.
In addition, Todd, while trying on hairstyles, asks "Mutton chops or Goatee" to one of the pair of twin guards, to which the guard responds, "Mutton chops, M'lord"; Todd's response is to tell the Guard, "No... shoot yourself in the head." which the guard does (Too dumb to live, so he killed himself, because he was ordered to do so) then Todd asks the other twin, who without a moment of pause or thought cheerfully responds, "Mutton chops!" then at Todd's stern look draws his gun and shoots himself in the head (Twins, too dumb to live... or maybe not), but wait, after checking himself in the mirror once more, Tod says, "You know, they have a point." The planet is essentially TSTL.
That isn't Tod's only TDTL moment. To penetrate the castle and save his wife, Richard Nelson aka Dad in the title, leads the idiot rebels (whose favorite weapons that their leader innovated are large smooth and round rocks which they hurl like shot puts) to build a giant hollow wooden statue of Todd and put it outside the castle. Todd is called to see it, and cheerfully rushes to look, then chides his soldiers on how it looks nothing like him, but instead of having them destroy it, he shouts to open the gates and bring it in to show everyone how much it looks nothing like him... though the rebels did nail the trapdoor securely shut.
Each member of the Mystery Team, but especially Charlie and (later) Jason. Jordy also qualifies.
Madison, the birthday girl in My Super Psycho Sweet Sixteen. While she and Skye, who happens to be the killer's daughter, are running from the killer, she picks that time to insult Skye again. You can guess what happens.
Chloe sits around in the dark, abandoned bathroom planning to spray Skye with a fire extinguisher. Can you say "Genre Blind"?
Everybody in Night of the Living Dead. Nobody in the film uses any sort of common sense, and it costs them their lives. In the original the character are to busy getting to each others throats than surviving against the zombies.
In the remake we have everybody as the original for all the same reasons except Barbara. She points out early on that the zombies are so slow they could just walk past and the idea is promptly shot down. Towards the end of the movie she escapes by simply walking past them without even firing a single shot.
In The Omega Man: Richie subscribes to the popular "Children are Too Dumb to Live" concept. After Neville cures Richie of the plague, Richie asks if he will cure the Family (the bad guys). Neville declines on the reasonable basis that they are homicidal maniacs who worship the plague and prescribe the death penalty for those who are not afflicted by it. So Richie decides, on humanitarian grounds, to walk into the lair of the Family and tell them about how he was cured and they can be too. It is a relief to see Richie exit the gene pool. Too bad he brings down the hero as a result.
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.
This could be explained by Esther's constant intimidation of the kids, since young children do tend to clam up and hide the truth from adults, even when telling it seems like the most logical course of action (such as in case with bullying).
The "Suits" decide to scrap the Jaeger program in favor of building "Kaiju proof walls". 5 minutes later, a Kaiju crashes through the wall in less than an hour. The Kaiju is only stopped by, surprise, surprise, a Jaeger.
And with that incident, you'd think that the "Suits" would go back to thinking that Jaegers are a better option. NOPE. They say that the walls STILL show promise. Which leads to riots along the areas of the coastal walls.
And when another Kaiju is shown to have a very corrosive acid, and WINGS, it's essentially proven that the walls are not only useless, but a complete waste of time to build. Consider how many Jaegers could have been built with the resources and labour taken to wall the entire coastline of the Pacific Ocean. Then consider that even if they couldn't go through it, they could go around, being shown to be entirely capable of moving on land even early on. And the complete lack of any active defences which allowed Mutavore nearly an hour of whaling on the Sydney wall to get through.
Newton announcing to a crowded shelter full of superstitious, frightened people that the Kaiju is specifically hunting him. Cue everyone backing away from him, making it very clear that they are fully prepared to sacrifice him to it to save their own skins.
Ofelia of Pan's Labyrinth surely qualifies in the infamous Pale Man scene. She has been warned by the Faun not to touch any of the food on display, or else; the magic book, just in case she forgot, tells her again... and guess what she does? She apparently doesn't notice the horrific looking creature sitting as still as a statue at the head of the table, never mind hear it springing to life as she takes a bite out of some fruit. The fairies with her even wave their arms and try to warn her not to, but she just greedily swats them out of the way and they end up getting eaten by the Pale Man for their troubles. To be fair, it's possible that the feast exerted a sort of hypnotizing effect on her. Pan's Labyrinth was influenced by various fairy tales, and such an effect is not unheard of.
Ofelia likes fairy tales, and the movie is set up like one. In some fairy tales (but not all), the main character will fail to listen to advice, or do something they were told specifically not to do. In some cases the tale ends here, otherwise the main character must do something to redeem themselves in the eyes of their quest-giver. So Ofelia is just acting in accordance with the fairy-tale princess that she believes she is.
Micah from Paranormal Activity 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 thinks the whole thing is some sort of fun horror game. Pity he's not Genre Savvy in the slightest.
In Perfect Stranger, Miles Haley finds out that Rowena Price, the reporter who was investigating her friend's murder, actually killed her after years of blackmail by the victim. After confronting her, he decides to blackmail the woman who just killed the last person who tried to blackmail her! His sudden death is well deserved.
ANYONE who buried anything in the burial ground in Pet Sematary after seeing the initial results (heck, after the initial warning for that matter). You'd think that after seeing what happened to Church the cat they would have stopped, but the guy then proceeded to bury his hit-by-a-truck toddler son Gage, who then came back and killed his wife. If that wasn't enough yet, he then buried his wife there, and she mercifully put an end to his chain of idiocy.
This is easily explained by the book. The burial ground calls out to people, and at one point the main character mentions that he feels great when going off to bury Church. Besides, the main character is insane with grief after Gage dies and just loses it when his wife and Jud get killed as well.
Then came the movie Pet Sematary Two (yes, there was a second movie), which was more of the same, but with most roles reversed either gender-wise or species-wise, plus a much higher body count, reanimated or not and a MUCH higher "creepy" factor in that the plot dared to bring up the utterly stay-up-all-night-thinking-about-it scientific side of the undead people/animals, courtesy of Dr. Chase Matthews the veterinarian: first the kids Jeff and Drew buried Zowie the dog after he was shotgunned by Drew's abusive stepfather Gus, and upon Zowie's return didn't really feel like there was anything wrong when the dog acted nasty — Zowie was probably just irritable from being away from home for a bit. More burials took place, including Gus himself and Jeff's actress mother Renee, who is taken from her grave much like Gage in the first book/movie. Interestingly, the undead Gus even does some of the burying, effectively enlisting Clyde the bully (who he killed while undead) as his henchman.
Pitch Black: Paris, in a fit of blind panic after a creature swoops on the group, screws over everybody by scrambling away, pulling out the battery powering the glow-stick type lights... including the ONLY source of light around his own torso. Karmic Death ensues.
Millburn in Prometheus, trying to pet an alien-snake.
And several others. Ignoring scientific procedure was quite common among these supposed scientists...
Removing you helmets in an alien environment. Even if the air is breathable, you don't know if there's any pathogens in it.
Finding an alien's head and trying to re-animate it with electricity, causing it to blow up.
Not having any sort of decent quarantine procedures outside on one scene.
Anyone in the not-remake of Prom Night (2008), especially Claire (Jessica Stroup) who sees the killer coming for her and just stands there and the local police, whose bumbling and ineptitude cause all the deaths in the movie.
Vincent Vega of Pulp Fiction. A veteran hitman who really should have showed a little more respect for his weapons, he ended up causing the Trope Namer for I Just Shot Marvin in the Face 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.
Vega is more careless than dumb, in large part due to him being a sociopath, as after Marvin gets shot, he doesn't even seem to care one way or the other about it and in Butch's case it seemed so absurd that Butch would actually come back there that Marcellus leaves to get donuts.
The rather logical explanation that Vincent is a moron because he is high on heroin for a good portion of his waking life has been forwarded.
See also the man who continues to obnoxiously say "What?", despite the armed hitman pointing a gun at him and furiously daring him to keep saying it. People afraid for their lives sometimes do dumb things, but doing the one thing you've been warned not to do is suicidally dumb.
See also Mia Wallace, purely because snorting a substance you found in the pocket of a virtual stranger without knowing exactly what it is is not a sensible thing to do.
The Purge: One of the Sandin kids lets a stranger into their house. It results in a home invasion, but it remains to be seen if it results in the Sandin's deaths.
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. He tried to collect every bill in sight, and is promptly eaten.
The Umbrella guard in Resident Evil: Apocalypse. Would you just look at that? A super zombie. Over three heads taller than you. Able to lift a gatling in one hand. Walking slowly towards you. Who needs to run? Two assault rifles should stop him. Shoot! What's this? Shrugging off bullet impact? Not slowing down? Oh no he is too close. Maybe this would work. (melee with rifle) Guess what happens.
On a more minor example, during a High Speed chase through a densely packed forest in Return of the Jedi, 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? Considering that Luke demonstrated that the speeders can change elevation, racing through the trees at ground level in the first place qualifies everyone involved. On top of that, after Luke had been knocked off his speeder, his foe doubles back to finish him off rather than continuing on to get help, as all of the speeder troopers were commanded to do (and is the reason why they bolted from the scene in the first place).
A reasonable argument could be that, once dismounted, Luke used Force influence to convince the trooper to swing around and try to kill him. If you watch closely, Luke pulls out his light saber before the trooper turns around.
Also, the Imperial ground forces in general in ROTJ deserve this. Locating your sensitive base in the middle of a forest where there's plenty of places for the hostile natives to hide? Oh, and wearing bright, gleaming white armor to a fight in said forest? Apparently, the Empire never invented camouflage.
In the Empire's defense the "hostile natives" were a bunch of 3 foot tall stone age tech teddy bears who were shocked and frightened by the concept of a hat. Keeping it hidden from your actual enemies who have the ability to fly and spot a large building in the middle of a deforested area seems to be worth the risk of giving said natives places to hide.
Robin's father in the Prince of Thieves movie. One of his servants runs to him saying that someone had taken the servant's daughter. And he promptly puts on armor, gets on a horse and rides out the front gate. Alone. In the middle of the night. And apparently without bothering to look out first because he's shocked to see a group of men in cloaks holding torches in plain view. And then he rides out to fight them instead of getting back inside, pulling the gate up and waiting for Nottingham and his dozen or so men to just give up.
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.
For a more detailed rundown, there's Addison immediately sticking a hand into the obvious bladed trap, and then, instead of keeping her other hand out to free the first one, shoves it in too when the syringe she's going for spills (and commentary reveals that the box had a key already in the back, so if she'd taken a few seconds to assess the situation she would have gotten the syringe with no trouble).
Obi, who walks brazenly into a furnace and seizes the syringe without a second thought. If he'd taken a few seconds to look around first, he would have seen the valve to turn off the gas and wouldn't have been burned alive.
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.
Also lampshaded at the beginning, when Drew Barrymore's character asks "Who's there?" the killer taunts her on the phone with, "You should never say, 'Who's there?' Don't you watch scary movies? It's a death wish. You might as well go outside to investigate a strange noise or something."
Only about three minutes after uttering the above line, Sidney is attacked by the killer and she actually attempts the front door first before realizing it's locked and she has no time to unlock it, which sends her running up the stairs.
Another character in the movie, Tatum (Rose McGowan) is killed after trying to crawl through the pet door in an automatic garage door. Naturally, she dies when the killer does something she wasn't smart enough to do: open the door.
Everybody in 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 programming. The screamers are programmed 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 ever seen. Now, the film implies that the Screamers were only set up and let loose by the Alliance after the planet's population had already mostly been killed off with bio-weapons and nuclear strikes by the NEB, and the Alliance was at the point of losing the war if they didn't do something crazy and desperate to change the balance of power. It's also pointed out by the surviving Alliance commander that this was a crazy act of desperation, and that there were all sorts of potential unintended consequences. So not quite Genre Blind so much as simply an attempt at Refuge in Audacity that didn't work out so great. Also, the Alliance troops did have an identification system they could wear, called a "tab," that was supposed to protect them from screamers. The system would have been great if it actually worked, but the film makes it clear that screamers looked at the tabs as just a thing that goes "ping". And the tabs were a system that said "I'm already dead, don't kill me" not "I'm on your side, don't kill me".
Will Stanton in The Seeker. At the end of the movie, he and the other Old Ones are forced to retreat into the Great Hall, where their enemy the Rider cannot enter unless invited. Will then proceeds to throw open the doors when he hears his parents and sister calling him only to learn that it was just the Rider who — oops — is now able to enter. Evidently Will thought his completely ordinary family was able to somehow get to a mysterious place which seems to be in an alternate time/dimension.
This is based on a very early scene from the book (The Dark Is Rising), where he, Merriman, and the Lady are holding a three-person circle of power in the Hall while the Dark tries to beat down the door, and they break his concentration by convincing him briefly that they've got his family captive. He lets go of his new comrades' hands, and the Lady has to temporarily die to save the day. Then Merriman actually explains a little bit, although he has an infuriating habit of explaining nothing, ever. (Will's also only just eleven in the book.)
Ed takes this to new levels and plays it for laughs. The characters need to get past a horde of zombies, and do so by acting like zombies to avoid drawing attention. When they are nearly to apparent safety, Ed's phone goes off... and he answers it and starts cheerfully talking on the phone, less than ten feet from dozens of zombies. Previously, he had "accidentally" crashed their first car, giving him an excuse to drive a Jaguar instead. Following after the cellphone incident, the electricity comes back on and he starts playing a pub fruit machine, which draw the attention of a zombie in the same building as them.
Shaun's mother should also be mentioned. What did she think would happen opening the door to a zombie?
Shaun himself also fits this. What exactly made the Winchester any safer than Liz's apartment? While it's got big heavy doors and a rifle on the wall and Ed knows where all the exits are (and he can smoke), they actually probably would have been safer in the apartment, because the window was above ground level (Shaun could climb up to it, but he wasn't a zombie) and you couldn't even get into the building without being buzzed in. Even if the zombies somehow got in through that door, they could have barricaded the apartment door fairly easily. But they also wouldn't have had half so much booze.
Let's not forget David standing right in front of the pub window, seconds before he gets eaten.
Frankly, the entire group lives and breathes this trope, making stupid decision after stupid decision, but Ed really is the king.
The entire human race falls into this at the end. After the Army restored order, someone had the baffling idea to round up the Zombies and use them as a source of cheap labour and entertainment, instead of destroying them! And if that's not bad enough, while they do take the precaution of putting restraints on them to keep them under control, they completely forget to muzzle them! Because it's not like Zombies are well known for infecting people by biting, right?
Invoked in the slasher spoof Shriek if You Know What I Did Last Friday the Thirteenth. 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.
The aliens from Signs walk around Earth naked, despite being as much vulnerable to water as we are to sulfuric acid. Really, just coming to a planet that's roughly three-fourths water probably counts.
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!
Interestingly, nobody ever produced a rational reason for the need to flee the scene, as there were a) the aliens are after humans, so LA provides enough targets for some time. Maybe they won't search the ocean for tiny boats with few people in them at all and b) where the aliens are, there will be the comabt zone. The Houskeeper even insist on staying in the "safety" of the appartement, after a nuclear bomb went off right outside the window.
Talking about that, keeping on with peeping through a telescope when what you see is a stealth bomber delivering a really big payload is not very sensible either.
Eddie Kim, Big Bad of Snakes on a Plane. Unleashing the titular snakes on the titular plane earns him the death penalty for multiple counts of murder and attempted murder. And it was all to silence a witness who survives anyway.
In Southern Comfort, the main characters are in the National Guard on a training mission in a swamp, miles from civilization. They see one of the inhabitants from a distance and decide to mess with him... by pointing their rifle (loaded with blanks) at him and "opening fire." Shockingly, the locals have their own rifles, not loaded with blanks. Natural selection ensues.
Actually, the shooting is done by just one guy, Stuckey, consistently portrayed as the biggest idiot of the bunch (he plays the same "joke" on his sergeant near the beginning of the movie). But they all get to suffer for it.
The news correspondent and the cameraman on Klendathu from Starship Troopers. They're on the surface while the actual battle is still raging. What makes them this trope is that they actually stop during a mass retreat to get some shots of the action, and are both promptly killed for their trouble.
Humanity in general has shades of this. The overwhelming majority of human characters regard the Bugs as mindless animals despite obvious evidence to the contrary. For example, early on the film, Bug plasma knocks an asteroid from the Asteroid Belt into Earth and it obliterates Buenos Aires; they did this from Klendathu, thousands of light years away. Something like this surpasses anything mankind would be capable of unless they had trillions of dollars worth of supercomputer, and the Bugs are doing these calculations in their heads. But nope, Bug plasma is "random and light". Even after the assault on Klendathu turns into a horrible failure that leaves thousands of humans dead and wounded, there are more than a few people who are adamant that the Bugs can't be intelligent. To quote one "expert", "I find the idea of an intelligent bug offensive!" One wonders if the Bugs find the idea of intelligent monkeys offensive as well.
The whole race of Romulans in the latest installment of Star Trek. Their whole sun goes supernova thus destroying Romulus in the process? Sorry, but you must be plain dumb in order to let that happen (according to Star Trek Online, they caused it by testing weapons that were banned due to this specific reason). Not only do they possess a whole star empire, which means they have more planets then just the one being threatened by the super nova, they should also have the technological possibilities to detect super novas in time. It's not like they happen as a total surprise. It shouldn't have been a problem at all to evacuate a planet in time. And to let Spock as the only person in the goddamned empire try to prevent it because they were too busy arguing. That's beyond dumb. Maybe more so, since the ship and technology Spock uses were built on Vulcan, which means somebody had sufficient advance notice and time to prepare a response.
Due to his wanting to show up the rookies, Olson waits until the absolute last moment before popping his parachute. Kirk and Sulu pull their chutes at a safe distance above the platform, but Olson turns out to have waited too long, and winds up dropping right into the path of the mining laser beam, completely vaporizing him and the explosives he was carrying for destroying the drill.
We also have the Vulcan bullies picking on Young Spock. It was clear from their reaction to Spock delivering a No-Holds-Barred Beatdown to one of them that none of them considered the possibility of their trying to "elicit an emotional response" in Spock might result in violence.
Star Trek: Into Darkness: The top Starfleet brass hold an emergency meeting on top of a tower with large open windows. It's not surprising when Harrison attacks them with a gunship. Especially because as Kirk noted only seconds before that happened, Harrison was a high ranking member of Starfleet himself and would thus know the protocol for the situation he created and where and when the top brass would meet.
Also Admiral Marcus, as noted by Harrison himself, thought he best way to combat the Klingons was to wake up a genocidal, sociopathic super-human and then threaten his family so the guy will build weapons for Marcus. Great plan!
In Star Wars: A New Hope, you'd think Admiral Motti would have known that dissing the faith of the big scary Sith Lord and personal hatchetman of the Emperor, Darth Vader, in his face is a very, very, very bad idea.
Keeping in mind when the scene was written — the Force had less presence in the material plane in the original script, thus people like Han Solo who didn't believe in the Force were the rule rather than the exception — Motti gets upgraded from Too Dumb to Live to Too Dumb To Keep His Job. Motti probably had never worked with Vader before and probably thought Vader’s reputation was just to scare rebels. He had no idea Vader was going to choke him with magical powers! However, it was still a pretty bad career move to insult the Emperor’s personal aide; he was a bold, outspoken guy whose candor had been appreciated, or at least tolerated, in previous positions which did not involve working with Ax-Crazy Sith Lords...
Then there's Greedo, a bounty hunter so amateurishly stupid that he doesn't get the most basic line you need to say when you are covering your quarry, "Keep your hands where I can see them."
In the Expanded Universe short story collection Tales from the Mos Eisley Cantina, it's revealed Greedo was not at all an experienced Bounty Hunter. He was a wannabe Hunter who was the target of a contract himself, as the last of a group of refugees/exiles from his home planet. His assassins tipped him off to the bounty and led him to Solo, knowing that Solo would easily dispatch him on their behalf.
In Attack of the Clones the changeling assassin. She was trying to flee the Jedi at every opportunity, clearly had the ability to change shape and had just ducked into a crowded bar. Once the Jedi entered you'd expect her to change shape again and run at the first opportunity right? Instead she deliberately attacked them and was somehow surprised when they easily disarmed her (literally).
Both the Jedi and Sith Orders in Star Wars, which is especially made clear in the Expanded Universe. The Sith are a bunch of psychotic power hungry madmen whose backstabbing ways are almost always the reason they keep getting defeated. The Jedi are a bunch of emotionally dead people with an obsessive desire to keep an ineffectual government from falling apart that otherwise would without them, eventually leading directly to their final downfall, and their rules toward squashing all emotion and overcautious ways have been directly responsible for the fall to the Dark Side of members of their Order and subsequent rise of many Dark Jedi and Sith Lords on a near constant basis for thousands of years. Neither organization learns much of anything from these constant mistakes despite thousands of year of opportunity, and as a result eventually both have to be destroyed down to the last man and rebuilt from scratch before any significant changes are made.
Very much Frank of State of Grace. A mafia boss who goes to extreme lengths to 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. It's really no surprise that he ends up being topped by Terry, his last remaining childhood friend, with even more added irony cause Terry was actually an undercover cop and was having qualms about busting Frank and the others.
The Stepfather 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 America's Most Wanted to her ex-husband saying that their youngest son told them that said fiance throttled him 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.
In traditional horror fashion, everyone else is just as dim. Everyone who finds evidence that the titular stepfather isn't who he says he is steadfastly refuses to notify anyone of note and putt around with the killer knowledge. Special commendation goes the supposedly Genre Savvy son who, despite being paranoid as sin, ignores several anvilicious clues that he's -right-. The ex-husband is also this, as he knows the stepfather throttled his son, steps into the room that he knows the killer is in, and goes in not assuming that he could be attacked. The cops at the end may also be considered this, if not 'Too Out of Shape to Live'; They fail to apprehend a man who has been stabbed, beaten, and thrown out a second story window. You could SEE THEIR LIGHTS APPROACHING while he was still sprawled out on the ground recovering.
The three victims in The Strangers; Kristen doesn't do anything but scream, trip and cry and actually injures herself, James among other things decides to go get a radio (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. They all die.
It was quite often stated that the cell phones had been disabled, very few people deserve to die for forgetting their phone in the car, but if anyone does, it's these two. I do agree their friend should have made more of an effort to announce himself.
They were thrown into the fire because they were charging... and they didn't use them to call before they got burned for exactly that reason. The film makes it clear that their phones' batteries were not dead. Trying a call, anyone? No? Ok... Have A Nice Death.
Lex Luther's cronies in Superman Returns Superman is currently throwing his newly created Kryptonian island into outer space with them still on it, and the entire place is falling apart. Luther urgently tells them to to get the hell out of there and don't stop to take anything so they can make it to his helicopter and escape. So what to they do? Stop to grab as much cash as they can before escaping, which slows them down long enough to be crushed by a pillar.
In Taken, Kim and Amanda are this. They are 2 American teenagers who go to France by themselves to follow around a band. They take a taxi with a stranger and then tell the stranger their apartment number and that they will be alone in the apartment. No surprise, within the first 30 minutes of the movie they are kidnapped. The criminals that take them could be considered this as well. They run on the premise that trafficking some young, pretty white girls from wealthy countries is the way to go, not realizing that even if Kim's dad Bryan wasn't a former spy who could kick their asses, the families of those girls would ask questions (and Missing White Woman Syndrome).
The behaviour of Kim and Amanda is not that far fetched, as anyone who has been around privileged teenaged girls who have spent their sheltered life in a gated community in suburbia can tell you.
And, as evident by Missing White Woman Syndrome even existing, this is not too farfetched on behalf of the criminals. Not every single person ends up in the news (and many who ended up in the news never led to a conviction). Combine that with the heavy implication that the French Police were being paid to look the other way and the high price they got for the daughter (probably not so much the friend), and it isn't that stupid.
In the sequel, Bryan tries to offer Murad a Last-Second Chance to walk away in exchange for leaving his family in peace. Murad blows it by going for Bryan's discarded gun... which was empty. Bryan promptly kills him.
Arguably Murad and his entire gang for their revenge plot against Bryan for killing their relatives (who were the antagonists from the first film). Their target is a Retired Badass who, in his singlehandedly tracked down and slaughtered anyone linked to the kidnapping/whereabouts of his daughter and did so by infiltrating a human trafficking ring and evading the French police who tried to arrest him for his vigilante methods. What was their plan? To kidnap his wife and his daughter as a means to get him to surrender to him. Even though they succeed by capturing his wife, which forces Bryan to surrender to them, the fact that they were more or less pulling the same stunt their relatives did (kidnapping/endangering members of his family) which was what put them in the line of Bryan's warpath in the first place, you can't help but feel that their plan was outright suicidal.
It's even worse considering that Bryan was also with both his wife and his daughter in the same country, so Bryan had an easier time finding where his wife was held hostage compared to the first film, in which Bryan had to start from scratch in another continent finding his daughter. Not to mention that Bryan, being an ex-spy and all, would had likely taught his daughter self-defense in order to prevent her from being kidnapped again (and as luck would have it, he is able to keep her on her toes in the sequel-despite being captured by Murad's gang, he is able to give instructions to Kim which allows her to evade capture from their men and ultimately locate and rescue him).
Kalle from The 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.
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. Admittedly she is 14, but in this day and age if a 14 year old girl does not even think to let a friend or family member know she is going to meet up with a stranger on the internet, and then ignores the cardinal rule of not getting into a car with a stranger (which hopefully most six year olds know by now) then she is clearly headed for a nasty shock.
In Urban Legends: Bloody Mary, the teens are all victims of their own stupidity. In the first two films, the victims were at least tricked or trapped by a killer that they didn't even know was running around butchering people but in the third film, all the kids were so dumb that they would have died with or without Bloody Mary's help.
Goddamn near everybody in the movie Warning Sign. Firstly we have the Biotek employees who unzip their hazmat suits inside a sealed quarantine room - where they're making a deadly Hate Plague - to pose for a photo. Then when the virus is released into the facility, the other Biotek employees apparently have no idea what a quarantine lockdown is, staring at the closing shutters and alarms in confusion and then get upset when they are locked in. They then try to argue with Joanie, the security guard who started the quarantine, to let them go because she was scaring people with the quarantine despite some of them knowing they were working on a hate plague. Then the concerned townspeople and relatives outside the quarantined building try to break their way in, despite being told the spin story that a chemical that would destroy their crops had been released inside. If not for Joanie having more common sense than everyone in the county and sticking to the quarantine protocols, Utah would have been screwed.
In Waterworld, there is a character named Enola who doesn't know how to swim, when 99% of the planet is covered in water. It's made very clear that she can be taught to swim and that no one ever thought that a child growing up on a planet covered by water should know how to swim.
Though it is not lampshaded, it could be that she was sheltered inside all of her life so that no one would notice her birthmark/tattoo. Wearing a bathing suit or skinny dipping, someone would eventually notice it.
Several of the children who potentially stand to benefit from the tontine in the British ensemble comedy The Wrong Box grow up to be too dumb to live, as shown in a montage following the opening credits. Just to name two, an army sergeant orders his men to fire a cannon, oblivious to the fact that he is standing directly in its line of fire, and a big game hunter insists on waiting for a rhinoceros to charge before opening fire, and waits so long that he is swiftly gored when it finally does start charging.
In X-Men Origins: Wolverine the military needs to stop Wolverine, who they've made immune to almost all weapons. To stop him they have at their disposal: An incredibly skilled marksman, and adamantium bullets capable of penetrating the adamantium shell around his skull and incapacitating him. Somehow the idea that they should combine these two things doesn't seem to occur to them.
Said marksman also thinks it's a good idea to take a jab at Wolverine when he has decided to let him live. After seeing the guy take down a HELICOPTER.
John Wraith, whose only power is teleportation and who thinks the best way to take down a big angry guy with claws and a huge healing factor is to punch him out.
The title characters in Yossi And Jagger. One could argue that the film works best as a hour-long PSA about Why You Do Not Have Affairs Within Your Chain Of Command.
Zombieland: Wichita and Little Rock ride the rides at Pacific Playland, which light up, make noise, and naturally attract lots of zombies. Many fans think they may have been deliberately suicidal, even.
First averted then played straight with Bill Murray: Using make-up and his acting abilities to blend in with the zombies and avoid being killed? Pretty damn friggin' smart. Pretending to be a zombie in order to scare the unsuspecting jumpy teenager WITH THE GUN? Stupidity of epic proportions, especially when he saw the reaction that he got from the survivors who weren't currently armed with firearms and then trying it again with someone who was...
Its important to remember that all characters involved are stoned out of their minds at the time they start thinking this is a good idea.
There is also the whole scam the sisters play, which relies on the mark doing very specific mistakes. To whit: Wichita tells the mark that Little Rock is infected and needs to be put out her misery, but Wichita can't shoot her own sister and begs the mark to do it. The mark has misgivings about shooting a little girl, Wichita agrees to do it herself, takes the gun, and then robs the surprised mark at gunpoint. If the mark is more pragmatic, there's a very good chance they'll just shoot Little Rock then and there.
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.
To be fair, he knew that using a lighter while covered in gasoline is a bad idea and tried to stop his friend.
The Animal Wrongs Group at the beginning of 28 Days Later. After being explicitly told that a monkey is infected with a contagious disease, one of them frees it anyway.
The US Army in 28 Weeks Later. They allow unsupervised access to an asymptomatic infected, who consequently infects someone. Then they evacuate another one to Europe where the whole thing starts all over again.
The initial mistake wasn't allowing unsupervised access, it was giving a civilian access to 'ALL' areas of the military installation, even the top secret areas—including the place where the asymptomatic woman was.
Even so, they lacked the most basic security measures, such as placing guards around an individual who carries the most dangerous pathogen known to humankind. Nevermind how children were able to sneak past the perimeter and outside of the safe zone as if they were sneaking out of a high school during a lunch break...
100Feet. A woman is being haunted by the vengeful ghost of her abusive husband. He's shown her that he can move anything in the house anytime he wants, so what does she do? She throws her wedding ring in the garbage disposal, then decides to fish it out with her hands. After narrowly avoiding losing her hand, she invites the neighbor boy over for some fun...
In general, any character who knows about the illicit/supernatural/criminal activities of the antagonists, then says, 'They won't harm me because of what I can tell the authorities.' Cue the death scene.
Most people in horror films, as they frequently hang out, party, and/or tour places full with danger, such as radiation-splattered ruins,piranha-infested waters, and various other places. Special mentions go to the Friday the 13th people, who keep going to Camp Crystal Lake, completely ignoring the growing number of mass murders that have taken place. Frequently lampshaded in spoofs.
The group of film students from Grave Encounters 2 makes the decision to break into an abandoned mental asylum in the middle of the night not in spite of the fact that it might be dangerous, but because they believe that it killed a group of people horribly. The results are somewhat predictable.
