Plot hole: Anderton's wife gains entry into the jailhouse using her husband's eyeball - but he's already locked up inside, so his eye would not still have access to enter as it pleased. Any place anywhere that would have any sort of security system requiring anything from a simple passcode to a card key to a retinal scan, would immediately delete the user in such instances from all rights. And would also certainly report on any attempted use of such (retinal scan, pass code, whatever). (02:00:45)
Suggested correction: I thought that this was a mistake as soon as I saw it on screen, but reconsidered. It's perfectly possible that there was some, probably human caused, delay in updating the security system. After all, there wasn't a rush to do it since they already had the chief on ice. Maybe the sleep jail was still on a legacy system without automatic updating. Just assuming that in the near future that all systems are all perfectly integrated and instantaneous does not validate this as a mistake.

Plot hole: When Sarah Paulsen pulls the necklace out of the water, the necklace clasp is obviously closed. Since the circumference of the necklace is too small to fit over the top of Anne Hathaway's head, why would anyone believe that it fell off her when she was running to the bathroom? The only way that could have happened is if the clasp (which we were earlier told can only be opened by a magnet) had opened. The trained security guards wouldn't have suspected something wasn't right about a closed necklace falling off over of her? They were following her. They saw that at no point did she lower her head on her way to the bathroom for the necklace to fall off over her head to begin with. It also could not have fallen off her when she was vomiting into the toilet in the bathroom since the clasp was closed. (01:18:25)

Plot hole: At the end of the film Mardukas reveals that he has been wearing a body belt packed with cash - "in the neighbourhood of three hundred thousand dollars" - ever since Jack detained him in New York. Are we to assume that Jack Walsh, an experienced, hard-bitten ex-police officer, now a bounty hunter who routinely chases down violent and armed bail absconders who would kill him without a second thought, didn't even perform a perfunctory search of Mardukas when he detained him? This man used to work for the Mafia! What if he was carrying a weapon? A body belt with three hundred one thousand dollar bills in it would be uncovered by even the most casual pat down.

Plot hole: The convicts remove the radar transponder from the Conair aircraft and put it aboard a tour plane to distract their pursuers. That won't work. By law the tour plane will have a working radar transponder of its own, and two working transponders that close together will show up on radar as a collision. Air traffic controllers would immediately alert emergency services who would, obviously, wonder how two aircraft that had collided had managed to stay in the air. Nobody disconnects the first transponder - Pinball carelessly tosses the second transponder under the rear seat of the aircraft (the implication being that it continues to operate, perhaps on backup battery power). He doesn't disconnect the original transponder either - Swamp Thing, a skilled pilot, does that. There is no time for him to do any of this before he is stopped by the female security guard anyway.

Plot hole: Spoilers. It's revealed that the barn game takes place at an old farmhouse owned by the family of Jill Tuck - Jigsaw's widow. It's public knowledge that she was married to Jigsaw and that buildings they owned served as the headquarters of several past traps, so the barn should have been investigated at some point in the meantime. Ten years have passed. It makes no sense that the barn was never investigated and that the bodies of the barn victims were never discovered.
Suggested correction: The game was unknown to police even 10 years after John died. Now they've found all his other games and his multiple lairs. There would be no need to continue the search.
Hogwash. They would have definitely searched known properties associated with Kramer and his family.
I agree. In the second Saw movie, the police discover that John Kramer is Jigsaw. With this knowledge, not only would the police be able to freeze his assets but, they would be able to look into his financial records and look into any properties he owns like houses, warehouses, etc. Since the cops now have a face and a name, it's a very big plot hole why they never searched his home or any other places. If they had, more traps would have been found and confiscated.

Plot hole: In the end, all they have to do is ask the President, when he's conscious (Liev didn't kill him; he just knocked him unconscious), who killed everyone in the control room and nearly killed him. He would know who the traitor is and it's not Salt - when they look back at the facts, they'll see how Salt only killed when she absolutely had to, and how she saved lives and stopped a 3rd world war.

Plot hole: Considering the incredibly elaborate plans Maddy makes to have her husband murdered after forging a will she knows is invalid so he dies intestate and she - as his widow - gets his entire fortune, you'd think she would have worked out one little fact - Edmund Walker does not die intestate. It is established in the film that the dud will supposedly written by Ned Racine replaces a previous, valid will which bequeaths half his fortune to his niece Heather. When the new will is declared invalid under Florida law the previous will takes precedence and Heather and Maddy split the fortune. In no way will Maddy get the lot.

Plot hole: Where do the flyers come from that are in the bags that are carried out of the vault and into the van? Danny and Linus couldn't have taken them down there and there is no room with the Chinese man. They are carried out to the van before the SWAT team appears, which means they'd have to have been in the vault to start with? In the commentary by Steven Soderbergh he acknowledges that there's no explanation. (01:35:05)

Plot hole: Harry tells Doc Ock that in order to find Spider-Man he must find Peter first. Doc Ock finds Peter with Mary Jane in the cafe and throws a car through the window straight at them, then later throws Peter against a brick wall. Any normal person would've been killed instantly (or very badly injured), and Doc Ock doesn't yet know that Peter is Spider-Man. Given that Peter is his only lead on Spider-Man, it makes no sense that Doc Ock would try to kill him.
Suggested correction: Doc Ock is being controlled by the arms. They aren't behaving rationally.
Creating a series of silly explanations for obvious plot holes never resolves them. These arms were not behaving irrationally. In many scenes they were shown to be very intelligent. A good example is the scene where they attack doctors who try to remove them from Doc Ock's body. Saying that they weren't behaving rationally is absurd.
He may not have been trying to kill Peter, he could've been trying to make more of a scene of his entry, so Peter would take him more seriously and tell him where Spider-Man was. He could've been thinking of it as a risk of killing Peter though, but his arms made him go crazy.
This is only a theory. Theories never resolve mistakes.
It's not a theory. When Otto is first giving his demonstration to everybody at his apartment, a woman asks if the advanced AI for the tentacles would make him susceptible to being controlled. Otto says that yes it would so he shows everybody the inhibitor chip that he designed so he would not fall under its control. After the inhibitor chip gets destroyed, it's seen that the tentacles have not only taken control of his mind by forcing him to commit crimes, but have slowly driven him insane.
This scene is much too confusing for many people. This entry is correct. This is a mistake.
If these tentacles wanted him to finish the experiment then they wouldn't make him kill the person who has valuable information for him.
The arms are influencing his thoughts but not controlling every part of him. Doc Ock still seems to have control when defending himself but they seem to work in tandem with Ock. The only time they work on their own is when he under anesthetic. As we don't see him before he throws the car, we can only speculate the arms were trying to hurt Peter by themselves.
It's a cool scene regardless man.
Killing Peter would probably send a message to Spider-Man as well, so Ock probably wasn't concerned about being gentle.

Plot hole: For a convicted murderer who violated her parole and assaulted her parole officer while escaping custody, Ashley Judd moves around the country and even boards airplanes with little to no problems.
Suggested correction: She was simply careful. There's constant manhunts for much more serious felons and parolees on the lam who seem capable of moving around without getting caught.
How did she keep the gun if she flew across the country?
She likely put the gun in her bag and then checked it with other passengers' luggage at the airport. As long as she wasn't carrying the gun on her, it would go through.

Plot hole: Patrick Redfern needs someone to be in the boat with him to corroborate his and his wife's deception and be his alibi. That is whole point of his wife lying on beach - he gets this when taking Myra for a ride - but it was portrayed as a random ride she got, he did not intend or plan giving her a ride, he did not see her loitering near the boat, or even in view of him untying the boat. Even if that was intention in the story for him to be seen ready to cast off, the movie viewers did not see her viewing him, only her appearing just before he was set to cast off. Without someone with him the whole deception would not work, he would have no alibi, he could have killed Arlena unseen.

Plot hole: Shortly after the robbery, Kevin Kline and Jamie Lee Curtis get together in a little flat and Kline calls the police from a landline to tell them who committed the robbery. In England this would immediately lead the police to the flat from which the call was made, and the person reporting the robbery would be the first person the police would want to find and speak to. Otto has handed it to them on a plate. (00:12:29)

Plot hole: Peter goes into Carl's mind to save Catherine. When he's in there he sees the tank with the water nymph. On the tank are strange symbols which provide the FBI with the clue needed to find the latest victim. Makes sense so far. But, go back to the scene just after the FBI have captured the comatose killer and are looking in his basement. The FBI are looking at the contraption that the killer uses to suspend himself over the victim. On the contraption is the same symbol seen later on the water nymph's tank. Why didn't the FBI follow up the symbol then?

Plot hole: The entire plot hinges on the villain's gang obtaining the tablet that allows admin access to the building's systems. However, it can only be unlocked via facial recognition and it is keyed only to Will Sawyer's face. In fact, when they finally do get it, Xia unlocks it by holding it up to Sawyer's face. So what was the point of trying to steal the backpack containing the tablet? Without Will to unlock it, the tablet is useless.

Plot hole: Robert first shoots the electrical transformer on the pole's top, then enters the bakery, slices the wheat sacks and uses electrical fans to create a dust cloud for a dust explosion. How are the electrical fans supposed to work after the electricity is cut?

Plot hole: Apart from the impressive pyrotechnics, what is the point of destroying the Blue Thunder helicopter? By far the most expensive, time consuming and technically complex part of producing any aircraft is the design and development phase - once the prototype is in the air production is relatively straightforward. The bad guys can make new Blue Thunders any time they like, and Murphy has destroyed the only evidence he has that there was a criminal conspiracy behind the whole programme - the 'videotape' he has of blurry, false coloured characters will convince nobody. Without the helicopter to back him up that tape is of no value to him.
Suggested correction: The Blue Thunder is caught on camera by a TV helicopter during the aquaduct chase which is evidence it existed.
A helicopter is filmed on CCTV, yes, which gives no detail at all to its use, where it came from, or anything about the conspiracy behind it. The helicopter is proof of the sinister plot and Murphy just destroyed it.

Plot hole: At the end of the film, we see Edward carving ice sculptures in his mansion. How did he get the ice up there? First of all, it takes place in a warm climate and I didn't see a freezer up there in the castle. He couldn't have gotten ice from town because firstly he had scissors for hands and couldn't have gripped the ice. And, even if by some miracle he could, he wouldn't be able to buy any from town because everyone in town but Kim was convinced that Edward was dead, she told everyone that they killed each other. And Kim didn't bring it to him because she told her granddaughter in the end that she never saw him again after that night. So where did he get that ice?

Plot hole: The killer shows up at the scheduled appointment at 8 AM. They kill the idiot blackmailer with an overdose of morphine. Remember, that morphine that supposedly killed Thrombey in 10 minutes. Marta finds the blackmailer at 10 AM...alive, and does CPR on them, keeping them alive long enough for the ambulance to come and bring them to the hospital, even if in critical condition. So we went from "kills in 10 minutes, you can't even try to save him" to "after 2 hours, you are still hanging on"? (01:56:10)
Suggested correction: Marta injected an absurdly large dose. A smaller overdose would not kill in 10 minutes.
I read that objection before. From 10 minutes to 2 hours there's quite a leap that the movie does not explain or address at all, if it were part of the plot they should have said why this difference, on something so time sensitive (of which they got the factual details wrong anyway). Even visually when you look at the dose injected to Harlan and the dose in the syringe for the murder, they do not look different. He even stabs her with the syringe. Which makes sense since he has no reason to leave her there with a small. Controlled overdose in her veins risking that she would be saved as it -almost - happens - it's amazing he got away with it to begin with because she is so dumb to show up for no reason in a derelict place without talking to her accomplice that passed her the toxi report, or anyone.Without a throwaway line from an investigator or anything of the sort ("but you injected her the wrong way, so she was still alive two hours after"), we are just left with an inconsistency.
Suggested correction: You've assumed a hell of a lot! Marta said Thrombey was given a dose of 100 mg (instead 3) of Morphine and would die in 10 minutes unless given the antidote. You just asserted that "Thrombey would die in 10 minutes" as if it was fait accompli, while Thrombey didn't die of morphine overdoes at all! (He cut his own throat.) For all we know, Marta's 10-minute assessment was a worst-case-scenario assessment. Fran's age and physique, as well as Marta's CPR, helped negate the effect until the ambulance arrives. If the medics administered the antidote, it could have prolonged Fran's life. Finally, 2 hours is the time after which the viewer is informed of Fran's death, not her actual death time. Most importantly, this happens in the medical world all the time: A person who is supposed to die after 3 days lives for 16 years. There are case-by-case explanations for each one, but they baffle the medical examiners at first.
Two hours is not my assumption or when the viewer is informed of her death; the killer gives the appointment to the victim at 8 AM and to Marta at 10 AM, so as I said, after 2 hours with 0 medical care on her she is still hanging on and with barely a little tap she is ready to dispense important clues. I go by what the movie says also about the 10 minutes overdose time. Of course if you tell me that baffling freak occurrences can happen all the time in medicine and that very precise statements from the movie don't matter because the character can just have gotten it wrong by over 10x and the movie does not acknowledge it at all, well, that's a very respectable opinion; mine is that fiction (a whodunnit, not a slasher flick with a killer surviving multiple gunshots and the like) is not reality and it should respond to higher standards than "I guess she was still alive somehow."
I re-watched the movie to verify that Fran was given an appointment at 8 AM. I discovered something new: The bottle that was injected to Fran contained only 5 mg of Morphine. That's 1/20th of what was "supposedly" given to Thrombey Sr. So, yeah, 10x is OK. In fact, 20x is OK.
No, no; it contains 5 mg of morphine PER ml, it's the concentration, not the total. Go back to the scene when Marta "messes up", the vials are the exact same as the one that Ransom injects (obviously, since they come from Marta's bag after all). It's new for you but I covered that already in the Factual Error about it. It's something that piles upon a previous mistake. She did not give him 100 mg of morphine because it would have emptied the vial (which is more than half full) and because a full vial of ketorlac would have killed Trombe regardless, at that concentration! The movie gets both the props and the medical facts wrong (100 mg of morphine does not even kill most patients, Harlan would have not died in 10 minutes especially since he takes safely big doses of toradol and morphine), but nothing - in the script - says that Marta or Ransom got basic medical facts wrong.
Okay! It seems mistake after mistake is piling up. Now, it appears Fran lived 4 hours, during 2 of which she was unattended. Plus, 100 mg of Morphine from a 5 mg/ml vial amounts to 20 ml of liquid. Well, now, everything you say makes sense... or at least most of the things. On the whole, I think it was a complicated situation.

Plot hole: When Frank Martin steals the Mercedes, how does Lai manage to open the rear door, get in the back and hide - all with her hands bound behind an office chair? Not to mention actually closing the door and hiding herself (and the chair) in the rear footwell long enough for Frank to drive off and not notice her until they are out on the road. (00:29:25)

Plot hole: The pictures used in the newspaper article regarding the fire are obviously taken after Ponyboy and Johnny ran away since Pony's hair is blond and Johnny's is short (their hair was cut and dyed after they ran, ruling out the photos being old school photos), yet Johnny's face is free of burns. This would mean the pictures were taken while they were hiding in the church, which would be impossible.
Suggested correction: They could just be an old photo. Taken a year or two back, plenty of time for them to look roughly the same but have their hair change wildly. Could have dyed his hair and then stopped or cut the hair and then let it grow.
