Halloween II picture

Plot hole: In the first scene Alice hears on the radio that three teenagers had been murdered in Haddonfield just down the street from where they live. Yet a few scenes later, the sheriff finds out from his deputy that 3 bodies have been found. Wouldn't the police department know that before it made its way onto the radio news?

Suggested correction: When Alice is on the phone, she tells her friend she can hear the sirens so the police knew about the bodies. As for the sheriff, he'd been busy with Loomis all night. He might have heard about the bodies in the house but figured the other policemen could handle it and that way he could continue helping Loomis. The main reason the deputy came to talk to him, however, was to tell him that his daughter was one of the victims found.

Halloween II was a troubled production, and the scene with Alice was added during re-shoots. Note that the previous scene with Mrs. Elrod also includes a news report about the discovery of the bodies. I've seen no concrete evidence of this, but I've wondered if the scene with Mrs. Elrod was shifted closer to the start of the film, and was originally meant to take place after the scene with the sheriff.

Good theory, but the deputy runs up to the sheriff and informs him for the first time of all three bodies.

The Order picture

Plot hole: How did a woman who had just escaped from a mental institution get out of the country so fast? Even if she had a passport already, she wouldn't have it - the hospital or her family would. How could she get it back from them without SOMEONE turning her back in to the institution? It takes a lot to get involuntarily committed in the US, and I doubt she could get un-committed that fast, even with the guy she tried to kill vouching for her.

Contact picture

Plot hole: During the Congressional hearing, it is suggested that the alien signal could have been faked from a satellite - as Ellie only has her own experience to go on, it leaves her believing what happened, but still with an element of doubt. However, as a professional astronomer, Ellie would have immediately dismissed this since a simple parallax (triangulation) would have confirmed that source was at the distance of Vega - a distance far too great for any rocket to reach. (This is mentioned in the book). In fact, this is mentioned early in the film, when the employees in New Mexico calculate the source of the signal while it is transmitting prime numbers.

I, Robot picture

Plot hole: Sonny hides among the 1000 robots in the big store room. They are all placed in very straight rows. Sonny would not be able to take over another robot's place in the grid (when he starts running we see a large robot-sized gap) without getting another robot to move. And while Will Smith is running around the rows, he would have noticed if the others moved to make room.

Suggested correction: Will Smith shot one of them, it's possible this hole in the front of the row caused that line of robots to move forward one spot, to complete the row again. As they did Sonny could have slipped in. When he spotted Sonny the first time Sonny was simply standing between 2, as Will Smith only saw them from the front at that point, when he started running it's impossible to notice a simple step forward of 1 row of robots and Sonny slipping in.

Hellraiser: Hellseeker picture

Plot hole: After Bret shoots himself, Trevor goes to look for Sage; considering she sort of tried to stab him to death when last they 'met', it doesn't seem likely he'd go to her for help, when she has become another person he can't trust.

Copycat picture

Plot hole: When SWAT enters Peters wife's room, the officer reaches for her neck and almost as soon as he touches her, he states "no pulse". This guy's EMT skills are phenomenal! Carotid pulse with a glove on in less than 2 seconds. This guy is good.

Battle Royale picture

Plot hole: After Nanahara and Noriko run away from Akamatsu at the school, Niida shows up from behind some bushes opposite the school and inadvertently kills Akamatsu with his crossbow. But Niida is Boy 16, which means he should still be in the school building (he's supposed to come out after Noriko, who's Girl 15). There's no way he has any time to get into those bushes.

Enigma picture

Plot hole: When the police search the white car and the barn they fail to find the compartment in the car behind the boot in which the decoding equipment was hidden. This is completely improbable. It was a standard car, the compartment was not a secret add on, and the police were supposed to undertake a thorough search of everything.

Theatre of Blood picture

Plot hole: Edward Lionheart severs the head of theater critic Horace Sprout while Sprout and his wife are asleep. (Lionheart gave them both a knockout injection). Sprout's wife (and his maid)discover the severed head in the morning, and both scream and faint. But in the next scene, critic Perry Devlin retrieves his morning newspaper and then reaches for his bottle of milk, only to find Sprout's head perched on the milk bottle. How did the head get from Sprout's house to Devlin's place?

Heat picture

Plot hole: In the scene after the bank job where Charlene waves Chris off alerting him of the setup, Chris drives away and is stopped by the cops to verify who he is. He has a fake ID and they let him go. The police CLEARLY know who Chris is and what he looks likes for most of the movie but somehow, those cops don't have anything with Chris' name and face on it?

Domestic Disturbance picture

Plot hole: In the middle of the film, after the custody hearing, Frank shows up at an event. Danny pretends that Frank dropped his wallet in order to have a brief conversation with his dad. Later, Rick confronts him about what they talked about. What does Rick expect? It's not like Danny will never be allowed to visit his father again. They are going to talk at some point. For Vince to expect that he will never talk to his father again is unrealistic.

Disturbia picture

Plot hole: Turner locks himself and Ashley in her car so he can confront her. However after his speech, Turner somehow manages to open the door without unlocking it.

Upvote valid corrections to help move entries into the corrections section.

Suggested correction: It is accurate that Turner can open the door without unlocking it, all modern cars can be opened from the inside whether the door is locked or not. Ashley never actually tries to open the door, she reaches for the handle and stops once Turner locks the door. Since the movie never actually shows Ashley try to open the door, this doesn't count as a plot hole. If anything this is a character mistake, Ashley should be well aware that she can't be "locked in" a car that new.

Four Brothers picture

Plot hole: At the start of the gun fight at the house, a snowball is thrown at Jack who then follows the person into the street. When they turn around the person is wearing a hockey mask and Jack realises he's in trouble. Jack would've seen the person wearing the hockey mask when the snowball was thrown, as the person had to be facing him to throw it. There was no reason after that for Jack to follow him.

Event Horizon picture

Plot hole: In the scene where Lewis and Clark nearly hit the Event Horizon, One of the crew is calling out the closing distance and another confirms this information. Regardless of clouds obscuring their view they were aware of their proximity and the fact that they were speeding towards it and forced to attempt an abrupt stop makes no sense.

Scream 2 picture

Plot hole: It is highly unlikely that the murderer knew Phil was going to put his ear to the stall when he heard the babbling. It is even more unlikely that the murderer is going to get him on the first stab through the stall. (Which also requires a lot of strength). We also have to assume that he spent time hanging out in the bathroom knowing Phil would go there to begin with, and that other two men with weak bladders were doing the same simultaneously forcing the victim to go to the stall to begin with. (00:07:45)

Suggested correction: The killer is incoherently whispering in a strange way in the adjacent stall to lure Phil to press his ear up against it. After stabbing him through it, the killer inspects the knife inquisitively, as if checking to see if he actually got him. While it's still not a terribly plausible scene, the killer's demeanor suggests that he encountered Phil in the restroom by coincidence and improvised the kill, rather than anticipating all of Phil's actions as part of a perfectly executed plan.

The general logistics and planning of the murder are a separate issue - because no, the murder was planned. The entry just says that it's "highly unlikely", putting it mildly, that the killer could guess the exact position Phil would pick to listen to the noise. Just a few inches up or down, left or right, make a huge difference. The killer looks at the knife admiring the results, because if he had any doubts that he got his victim, he'd be trapped in a bathroom with a screaming, wounded, angry Phil and plenty people who could come and help.

To be more clear, the correction here is that Phil had heard strange talking/whispering rather than music, which makes it at least a little more plausible the killer would think he might put his head up against the wall at a certain spot. Unlikely for sure, but unlikely isn't a mistake, it's just what movies do. Phil's death was planned yes, though it stands to reason the plan was more "surveil and strike when vulnerable" and less "wait for him in this particular stall we know he'll be next to."

The House of the Dead picture

Plot hole: When the main bad guy is being hung as a normal human character, he speaks as he is being hung. However people cannot speak when they are being strangled. (01:15:20)

Angel Heart picture

Plot hole: When Angel comes back to the doctor's home with food, he opens the bedroom door and turns on the light in that room. The lights are already on outside this room when we see him turn the doorknob. When Angel leaves, he leaves the light on in the bedroom and heads downstairs. Just before leaving out the front door, he turns off the light switch nearby. The shots changes to show the doc's body and the room going dark- as if Angel is still in the bedroom and turned off that light. (00:23:10)

North by Northwest picture

Plot hole: When Eve is being led out to the airplane, she bolts when two shots are fired from inside the house (presumably Anna firing at Thornhill, not realizing that the gun was loaded with blanks). Moments later, she jumps into a car driven by Thornhill, and they escape together. There is no way Thornhill could have gotten there that fast, given that he was in the house only seconds earlier.

The Fog picture

Plot hole: When the fog finally hits the lighthouse and is seeping in, the generator is hardly audible vs. how loud it was when it was first started.

The Deep End picture

Plot hole: When Margaret has to collect the $50,000, she goes around to various banks trying to get a loan on their house, which she can't get because her husband, co-owner of the house, isn't around. Why couldn't she just have taken the papers, said she was going to take them home to her husband, forged his signature, and brought them back? You can't exactly say she has either moral problems or isn't devious enough, since we've already seen her stuff a body into a dinghy, toss it into the lake, and come back to her house looking fairly normal.
