Stupidity: Dr Faxx knew full well that Nuke was Cain's greatest weakness, but it never occurred to her to mention to the old man that holding a canister of it in front of him during the exhibition could have serious consequences. Not very bright.
Stupidity: When the two Russians are walking past the security guard after killing Gregor, they are just allowed out without being detained because one of them shows a Chilean passport. The French gendarmes are not that incompetent. They would detain the men until everything is (or is not) cleared up. (01:49:05)
Stupidity: The secret service officer near the elevator gets shot right in the middle of his head by the Penguin mascot, and she drags his dead body into the elevator. Suddenly he's able to moan and groan and she shoots him again. The guy was very shot in the head, as in graphically. How is he suddenly alive enough to moan?
Suggested correction: A bullet to the head is not guaranteed to kill someone. Movies and video games have taught us that being shot in the head is instant death, but that just isn't the case.
Pretty sure you wouldn't wake up in seconds after a bullet to the head.
Correct. You probably would just lay there stunned while moaning and groaning... exactly like the scene depicts.
He didn't "wake up", he moaned. Which is 100% possible and actually happens quite frequently.
Someone I know shot himself in the head. He was making sounds when found and "lived" for another three months, though there was no higher brain function anymore.
Stupidity: When the flying snowmobiles attack, Bond tells Elektra to go into the gully, and he'll lead them into the trees...completely ignoring the fact that these bad guys are here to kill her, so why would they follow him instead? Of course they all do. Either a plot contrivance or a blatant set up, which he doesn't remotely consider.
Stupidity: The Foot Clan knows that April O'Neil is an ally of the Teenage Mutant Ninja Turtles. Since the Foot Clan hasn't been able to find the Teenage Mutant Ninja Turtles for where they live a easy solution would be for them to go to April and ask where are the Teenage Mutant Ninja Turtles. An explanation is never given in the movie for why the Foot Clan never use that easy solution.
Suggested correction: First of all, the Foot Clan at the beginning of the movie is disorganized. Secondly, upon Shredder's return, he plants a Foot soldier named Freddy into April's news crew in order to keep an eye on her and find out where the Turtles are. Then they change tactics when they discover there is still some of the mutagenic ooze around, which they then decide to use to create their own mutants to lure the Turtles out of hiding.
Stupidity: Harrigan leaves his partner's badge on his grave where anyone could take it and use it to impersonate a cop or abuse it in other ways. (00:50:15)
Stupidity: In the Anubis universe, immediately around the time Lawless says, "Something's wrong," if you look closely, by Lawless, you see the two police officers behind Jet Li walk away to leave Lawless completely unprotected from behind. I understand it's a parallel universe, but that's some really bad police work to leave a prisoner wide open like they do.
Stupidity: The Chief Inspector wants the video cassette back because it shows him committing murder. Yet he spends the entire movie shooting and killing people in public trying to get Johnny and the cassette.
Stupidity: When Jonathan is chasing the truck to try and save Sarah, he could have removed his heavy backpack and run faster...but instead just leaves it on. No wonder he wasn't fast enough.
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: In the bar scene, Jack gets into a fight with a guy he busted a few years back, then Reggie turns to the bartender and asks for a gun. The bartender hardly hesitates and hands it over. There is just simply no scenario where a bartender would hand a loaded gun to a patron they had just met.
Stupidity: Anyone with a job in the White House would have to be known to the Secret Service on a daily basis, so the two Secret Service agents that find Cory the janitor should have been aware of his identity without him having to state who he was and that he worked there.
