Best action movie stupidity of all time
Stupidity: The Death Star comes equipped with a powerful tractor beam capable of capturing a ship the size and agility of the Millennium Falcon. Why don't they use it against the rebel fighters attacking them at the end of the film? Okay, Obi-Wan Kenobi turned it off earlier but I find it hard to believe that someone who has never before visited the largest, most complex space station in the Universe and who was previously unaware of its very existence can disable a fundamental security system but the people who designed, built and run the damn thing can't work out how to switch it back on.
Stupidity: Lao Che's intention was to kill Indy. He had no intention of giving him the antidote. So then why would he bring a real antidote? Why not just fill it with something else instead? From his perspective, bringing a real antidote was a waste of time, and also very stupid in case Indy managed to get it, which he did. In fact, Lao Che could've brought a fake antidote and given it to Indy. He probably wouldn't have noticed the difference, and then there wouldn't have been a fight in which one of his men was killed.
Stupidity: When Flint Marko is escaping from the police, he climbs a chain link fence into a test facility. Besides having a chain link fence, there should have also been security cameras around the area as well as guards to prevent anyone from trying to get in. Plus, when the scientist notice on their computers that there's an increase in mass, one of them simply assumes it's a bird and then they continue their experiment. Instead of making assumptions, they should have halted their experiment and have someone take a look to see what caused the increase of mass.
Stupidity: Reliant's prefix code is 16309. This code prevents an enemy ship from ordering a friendly ship to lower its shields or something similar. Five digits with no symbols. We know that symbols and letters aren't used since Spock uses a 10 digit set of switches to input the code. This is ludicrous. In 2016, a high powered server could crack a 6 digit password in approximately 0.0224 seconds (at 100 billion guesses/second). Any starship computer would have to far more processing power then a 2016 server. The prefix code protecting a starship from cyber attack would have to be insanely complex in order to be useful.

Stupidity: During the execution scene when Carina is on the gallows with a noose around her neck, the plot depends on Henry being able to get to her before she is dropped through the trap door. However, there is so much slack in the hanging rope that during the chaotic fighting, when Carina is left unattended, she could easily have stepped off the small trap door and onto the solid flooring that is inches away. Instead, she continues standing there, waiting to be rescued.
Stupidity: It's stated that Imhotep will fear cats until he has fully regenerated and two different scenes show him fleeing in terror at the sight of a cat. Despite this, none of the characters that Imhotep is trying to kill that are fully aware of his weakness even think to have a cat with them at all times.

Stupidity: Red and his gang have a barn full of stuff and talk about other couples and people they have kidnapped, robbed and probably killed. This indicates they have been in the "game" for a long time and been successful to avoid capture this long yet when Kurt Russell didn't want to get in the car, instead of cutting their losses, they went along with kidnapping his wife and initiating the whole ruse of her never getting in Reds truck which is what led to their downfall. Someone with the experience of this that Red has should know not to take such a big risk with a complicated story.
Stupidity: In the scene where Sam Neill and the little boy are climbing down the tree, the car keeps crashing down a few branches at a time behind them. Why are they in such a hurry? If the car is falling in such a straight line, wouldn't it be easier to climb around to the other side of the tree, where they would be safely out of danger?
Stupidity: Early in the film, Peter Parker desperately wants to see Mary Jane's performance, but he is turned away at the theatre doors because he is a few minutes late. Defeated, Peter shuffles away and sulks. Seriously? Why couldn't Peter simply enter the theatre through a side door or the roof? He's Spider Man.

Stupidity: At the start of the tanker chase Sanchez shoots at Bond. He manages to get in the cab and throw the driver out, who lands on Sanchez's car. Sanchez then gets in front of Bond and has the ideal opportunity to just shoot the cab up with his machine gun knowing Bond is driving, but he doesn't.
Stupidity: In Superman 2 he was able to use frozen breath to stop a trucks fuel tank from exploding. Why didn't he simply blow the factory fire out? He didn't even bother trying. Heck of a lot easier than taking water from a nearby lake.

Stupidity: It's perfectly legal for cops to hold suspects at gunpoint when making an arrest. So when Newman caught Royce holding Sheridan at gunpoint, he could've just taken him into custody and killed him later. Instead he does the stupidest thing possible, he shoots Newman, which also lets Sheridan escape.
Stupidity: In the scene with the water-jug puzzle, both Zeus Carver and John McClane initially suspect that the small carrying case contains a bomb. McClane goes ahead and opens the case, which confirms that it is a bomb (the electronic readout in the case even says: "I AM A BOMB. YOU HAVE JUST ARMED ME"). If they suspected it was a bomb in the first place, why didn't Carver and McClane immediately try to warn the dozens of pedestrians all around them to evacuate the area before McClane opened it? That would be a seasoned police officer's first instinct. Instead, McClane and Carver banter and bicker and never attempt to warn the public, even as the timer is ticking down.

Stupidity: When Pollux admits to Castor (really Archer) the bomb is in the L.A. Convention Center, Castor gives Pollux a strange look and tells him he's so pathetic (as if he's turning on him). It seems those actions and that comment made Pollux immediately suspicious something was wrong. Castor should have just heard the location and said "Cool" or something like that, then changed the subject so nothing would seem wrong.
Stupidity: A trained CIA hitman wants to kill the owner of a bar. Why would he go into the bar during opening hours, ensuring that there are witnesses to be eliminated, when he could break in after hours, use a few less bullets, and have fewer loose ends to tie up? The break-in would also provide a cover story for the kill. All rather unprofessional.
Stupidity: Mitch didn't have to die. Since the door is tension loaded, just open it, prop something under it while everyone goes through, then remove whatever you used to prop it open (there's no shortage of loose objects around!) If the current flow is a concern, just have the two strongest go through first (Ben and Mitch), they brace up against the object holding the door open, everyone goes through, then they just remove the object so the water is trapped inside as depicted.
Stupidity: Staff Sergeant Duquesne is tossing and flipping rifle grenades before affixing them to his rifle to launch against the German tanks. A battle-hardened no-nonsense sergeant like Duquesne would never waste valuable time showing off, and would definitely not flip or toss around explosive ordnance like rifle grenades.
Stupidity: When Tony watches the recording of his parents killing by the Winter Soldier, you see the latter shooting the surveillance camera (why there was a camera there in the first place is unknown) in order to avoid being recorded. That is obviously idiotic, since shooting a surveillance camera most likely doesn't result in the destruction of the recording, which is typically kept off-site as well. He should have destroyed the camera before being recorded himself.
