Plot hole: There is no reason at all why, being targeted by a few arrows by unseen enemies - a fire suppressed already by the salvo of their own archers - the Rourans would turn around their heavy siege equipment, away from the bulk of the enemy forces, and fire it, hurling a single heavy stone to the middle of nowhere when they have the whole rest of the army who could storm the rock the supposed enemy commandos hide behind, or the archers who could keep shooting - again, they proved to be completely successful. It also makes no sense that the all-powerful witch who made the warriors flee managed to do any of this, 'sneaking' by horse in the middle of the steppe.
Suggested correction: Mulan used the helmets of the fallen warriors to make it appear that a large force has flanked Rourans. Rourans didn't expect this new "force" and knew nothing about it. They didn't know its size. And while their original target seemed harmless, this new "force" was killing Rourans. Fear and death were the reasons. What you see in this scene is an enactment of one of Sun Tzu's famous quotes: "All warfare is based on deception. [...] Attack him where he is unprepared, appear where you are not expected."
What we see in the scene is laughable, and not because of the idea, which surely is based on the profound strategic motto you mentioned and we find in many folkloric tales in other cultures as well; what we actually see in the movie, is that she grabbed a couple helmets lining them up on a rock, and she shot a few arrows. Then she stops shooting, and we see helmets knocked down in their full view. The movie truly surpassed itself in showing it in the most phony way; had they shown her shooting from behind the rock responding to their fire, or the helmets not falling, or them just shooting at mist, terrified, it would have maybe worked. It's an enormous overreaction. That and, under no circumstance trebuchets are used that way anyway. And she did all this setup unseen, again.
In response to death, nothing is an enormous overreaction. Something or someone was killing them. They wanted to kill it, and they didn't have time for Facebook's famous brand of pseudo-myth-busting. What if they knew it was one girl shooting at them? They'd still have done the same. Being killed is a very personal matter.
Plot hole: There is no logical reason to switch off the Bombe at midnight when the codes change. Firstly, Turing's proving the concept of automated code breaking, so even if it only finds the right settings days or weeks later, the experiment is worth doing, then you can work out how to speed it up to be operationally useful. Secondly, even in steady state operation, cracking "yesterday's" settings (and thus intercepted signals) is still going to be pretty useful in most cases. Threatening to smash the Bombe up at midnight is good stuff to add some movie tension but, in reality, it's nonsense.
Suggested correction: It's not a plot hole, it's how they operated it in reality.
I have a copy of British Intelligence in the Second World War, by F H Hensley (the official historian and ex-GCCS). I quote page 309 as an example - 'the knowledge of the Tracking Rooms was far from perfect on account of delays in breaking the settings...During the first half of 1943, however, while the traffic was read with delays that were sometimes less than 24 hours, days when the settings proven to be unusual stubborn were not uncommon...Between 10 March Andy the end of June the setting standards for an a further 22 days were either not broken at all or broken only after a long delay.'...'A delay of as much a said three days in learning that U-boats had been ordered to move to new position so could thus mean than intelligence was received too late to be of use in diverting convoys'. So pretty clear that they carried on attempting to crack the settings well after the end of a day so they can process intercepts which might still be relevant.
Plot hole: When Claire is getting interviewed at the FBI building, there's pics of inside the bank during the robbery, even though the security tapes were destroyed in the microwave.
Plot hole: When Evan is in jail with the religious prisoner trying to get him to help him get his journals back he goes to the scene where he is drawing that homicidal picture in kindergarten, but he gets up and puts the spikes that holds documents through his hands, creating a stigmata-style scar. The religious guy in the cell with him is so amazed because of this he thinks Evan is a prophet and he decides to help him. If Evan had gone back in time and got those scars on his hands, he would have changed the original timeline and would have arrived in jail with those scars the whole time. Some people try to correct this using the "If I can create scars, then can I fix them?" statement Evan made to defend the mistake and suggest he can create instant scars but he was using the word "scars" to refer to the negative events; not literal scars on his body. The scar he got when he burned himself in the past didn’t magically appear on him the moment he returned from the past; it became part of a new, slightly altered timeline (just like the scars on his hands should have been) and it let him know he can change history.
Suggested correction: This isn't necessarily a correction so much as a possible explanation. It's possible that the religious inmate (I think his name was Carlos) just simply didn't see the scars on Evan's hands when he first came to the prison in the timeline where he got the scars or Evan knew to hide them in the scar timeline (due to the fact that it was the sole purpose of him going back) and due to his fanaticism he didn't question him a second time.
Nope, after jamming those things in his hands Evan simply came into the prison with the scars already on his hands and would have never thought of showing the religious guy his powers using that particular moment in the past to convince him, or doing what he did a second time as he already had done it. It doesn't matter if the religious guy didn't see them before, they won't be the object of Evan convincing him. He would have had to try it some other way, each and ever time. That how this time travel works and its definitely a plot hole that it worked as it did, whilst it shouldn't have. Of course, it's a time travel movie and they never make sense.
Plot hole: When Tim Robbins is floating away in space his wife could have easily saved him. She could go out a little further, use the grappler to catch her husband, then use the fuel she has remaining to halt their acceleration towards the planet and return them partway to the necessary orbital altitude/velocity to rendezvous with the resupply module. Then, Gary Sinise could come out partway to them using his thrusters, Connie could shoot the grappler out to him, and he could reel both Connie and Tim Robbins back in to the resupply module.
Plot hole: I have never seen a Daytona 500 race where the winner is immediately left completely alone and is able to walk over to his crew chief who is still at the pit wall and hold a quiet conversation.
Plot hole: Toward the end of the movie, it is revealed that Silvia spent the night in the secure room where the Matabo President was taken after the assassination attempt so that she could be alone with him and threaten to kill him. With the U.N. and Secret Service on alert for an assassination attempt, wouldn't they have swept the secure room right before the Matabo President arrived that day? In addition, Silvia would have had to use her access card to get in that area of the building, so there would be a record of her being in the building but not at her station. Wouldn't that raise some suspicion long before Tobin figures it out?
Plot hole: When the President of the United States attends a public gathering (such as the SuperBowl) the level of security is extremely high. So why wasn't Mason's delivery on the day of the game checked for explosive devices?
Plot hole: When Diana turns up at her director friend's house she finds it crawling with cops as his girlfriend Christie has been murdered and the house is now a crime scene. She explains she lent Christie a coat and is there to pick it up - and a cop helpfully finds it on the floor and hands it to her. Are we to believe that a homicide policeman will hand over an artifact from a murder scene to an unidentified woman without making any attempt to confirm her identity, or even if the coat is even hers!? They don't even ask.
Plot hole: The original ending planned was a massive tropical storm/water based chase scene. However, this was decided to be too expensive, and was switched for a cheaper, and some say weaker ending. Nonetheless, in Nicholas Cage's final speech, he says "I keep thinking about that tunnel, and what would have happened if I'd drowned." This makes no sense, given that in the new ending he came nowhere near a tunnel or drowning.
Plot hole: There's no way that Eddie and Nana left the flooded theater without getting a single drop of water on them. The water flooded up to the ceiling and there's no other way to exit besides the front doors, and Moon's secret exit, which also floods. They do not leave through either way.
Plot hole: George Lebay says that his brother died "6 weeks ago" inside Christine and that's why he's selling it. Later that evening after Arnie leaves his house and goes to Darnell's, Will Darnell says he "knew a guy who owned a car like that" and "the bastard killed himself in it." If it's only been 6 weeks since his death, shouldn't Darnell have recognized the car? It's not like there were lots of red Plymouth Furies (custom order color) running around the small town, let alone the USA, even in 1978. (Also considering how production even had a hard time finding them for the movie).
Suggested correction: He says he knew a guy with a car like that. It doesn't have to be the same colour or even the same generation. Just a Plymouth Fury.
Darnell basically said he knew THE brother of Lebay, not just some guy who owned a similar car. Darnell described Lebay's brother based on the story. Again, it was him, not just some other guy.
Plot hole: Despite their awareness of the red matter and the power of the singularity, no one on the bridge had the common sense to suggest pulling back to a safe distance. Nero had already refused their assistance so there was no need to stay so close to the singularity. And when a black hole was created inside Vulcan, an officer mentioned they had to reach minimum safe distance, so they know what they need to do, but no-one does it. (01:00:30)
Plot hole: Sgt Monfriez would have never been on a medevac helicopter with an automatic weapon. I served several years in U.S Army Medical units and they are allowed defensive weaponry only, medical units are not ever issued automatic weapons period. The plot says the Monfriez is from another unit and is asked to accompany the medevac but that would never happen; it is against the law of land warfare to put an automatic weapon on any type of ambulance vehicle.
Plot hole: Frank Miller sets fire to the stable Kane is hiding in; when he leaves it, you can see the large column of smoke. But the fire is ignored after that. In an age of wooden buildings and poor fire equipment, that could have burned down the whole town. Even assuming that people wouldn't come out to fight the fire during the gun battle, you'd think that when they all came out at the end, someone would have pointed out they had a major fire to deal with. (01:16:40)
Plot hole: During Howard's flashback the viewer sees from his point of view the two SS agents who had been following Enrique fire multiple shots at the now revealed Spanish police officer as he was talking to another police officer (Javier) who had just approached him. The scene ends leading the viewer to believe Enrique was killed by the SS agents. However, in the final scene when it's revealed that he was in fact killed by Javier the SS agents significant fire (9 shots I counted) and presence is completely forgotten. (00:40:00 - 01:12:00)
Plot hole: At the beginning, it shows Santiago crossing the border into the U.S. But the U.S. border patrol is on the Mexican side.
Plot hole: At the end, when Chris finds the informant's phone, he sees that there are 2 voicemail messages. Instead of listening to them, he calls the last number, which reveals Abel is responsible for the break-in when he answers and in turn reveals to Abel that Chris knows about the break-in. It would make more sense to just listen to the voicemails, as Chris became immediately suspicious when he saw them. Considering Chris called the last number, he must have known that the last number was also the person who left the voicemails. Very deliberately done to bring realizations between Chris and Abel for a climax.
Plot hole: After the scene at the Houses of Parliament where Irene Adler escapes through the sewer from the clutches of Lord Blackwood, she suddenly appears at Tower Bridge, about 3 miles away. Even assuming she ran there and the journey was skipped, going there makes zero sense. It slows her down, leaves her exposed and limits her exit points - she's got all of London to escape into! (01:48:00)
Plot hole: When the bomber is surrounded at the end he gets shot in the leg but manages to get away from all of the police that were surrounding him. They were literally an arm's length from him.
