Plot hole: Since they took down the telephone network, it would have been impossible for Justin Long to even be speaking to the emergency response woman for the car, much less send a signal to start the car up.
Suggested correction: Is it possible this is a satellite phone call akin to Onstar?
No, the BMW system requires a cell signal to work, which was taken down earlier in the movie.
Plot hole: After Superman has reversed time the Hoover Dam reverts to its previous undamaged state as it should, but Jimmy Olsen should then have been replaced back on the dam. Instead he interrupts the potential kiss between Lois and Superman and complains of being abandoned by Superman in the desert.
Suggested correction: Superman is moving at speeds fast enough to turn back time. He can spend 5 seconds to yank Jimmy away from the top of a dam he knows is going to be destroyed just to be safe in case he can't actually stop it all from happening again.
Plot hole: The factory in Norway has to be destroyed - at huge cost - as it is producing fuel for the V2 rocket. That fuel was ethanol - ordinary industrial alcohol. There is no reason at all to have a specialised factory hundreds of kilometers away producing such a simple chemical. The Germans could have manufactured it in virtually unlimited quantity in an ordinary brewery - and there were plenty of those in Germany.
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.
Plot hole: When Astrid gets on Toothless for the first time, Toothless takes off uncontrollably and tries to scare her. Hiccup seems to have no control over him at this time. How is that so if with the new tail fin, Toothless cannot fly without Hiccup's precise control of the tail fin? That whole sequence would have fallen apart. This mistake was even admitted to on the DVD commentary. (00:53:35)
Plot hole: Joy and Sadness are stuck outside of the control center. They are trying to figure out how to get back, and encounter maintenance workers who are discarding old memories. The maintenance workers show that they have the power to send memories back up to the control center to be played. Why couldn't they send the core memories that Joy had back up the same way? Better yet, why not use that method to send Joy and Sadness back up to the control center? The director of the film is even aware of the plot hole, and said "Yeah, well then we wouldn't have a third act," before explaining how the idea of recalling memories was added in later, "box[ing] [the screenwriters] in a corner a little bit."
Suggested correction: Even if they do send the core memories up to headquarters, they wouldn't be able to get joy and sadness through the tiny gap that the workers send the memories up. Joy has to be in headquarters for Riley to be happy.
This mistake is large enough that the director is aware of it. I think that more than qualifies it to be on this site.
Suggested correction: Joy is a control freak, she wants to return the memories herself. She doesn't even imagine that the workers can do such a thing.
Plot hole: At the start when the guys are infiltrating that building they parachute down to the roof. They are dressed in black so they can't be seen, but their parachutes are white. (00:02:50)
Plot hole: In Paris, why does the assassin go to the ridiculous amount of trouble of swinging into the room on a rope with a machine gun when he came in from the lobby (as proved by the dead woman downstairs)? Alternatively, if his intention was always to surprise Bourne by coming in through the window, why venture downstairs at all? (00:44:07)
Plot hole: When the first security guard, who stayed back to get something to eat, hears something in the laundry room, he walks over to the washing machine where he finds the head of the other security guard inside. He turns around screaming and trips over the security guard's body on the ground with no head. Wouldn't he notice the dead body on the ground when he first entered the room?
Plot hole: They aren't able to travel before the birth of their children or their children become different. Despite that, he visits his father one last time before their third child is born. His Dad and he then travel back to when he was a kid, which would have changed his first 2 kids.
Suggested correction: This is not necessarily inconsistent with the movie's time travel logic. Since Tim goes back in time to visit his father and inside that particular time travel, they use time travel to go back to a day where Tim was a child. Then, they return back to the original time travel where they're playing ping pong. At that moment, both of Tim's kids were already born. So, when he returns from the ping pong scene, there's no change regarding his kids.
Also, paraphrasing the Dad, he said they aren't going to change anything. It is more like reliving a memory than changing the future to get what you want. The Dad couldn't go back to not smoke before his kids were born because that was major and would have changed the course of his life; walking a bit differently on a secluded beach that you walked on in your younger days (as long as you spent the same amount of time - presumably) would not alter the trajectory of one's life.
The slightest change in 1 second of being on the beach would absolutely affect his kids. A man produces 1500 new sperm every minute. Altering the timeline and delaying every event that is going to happen by literally 1 second would most definitely alter which exact sperm was used when conceiving both of his first two children.
Plot hole: In the unedited video footage of the helicopter incident shown to the crowd, the last shot of Arnie getting knocked out is seen from his perspective and as such could never have been filmed by any camera.
Plot hole: The movie is based on one huge plot hole: if it wasn't for the "professional" hitman's sloppy work, Bullitt and his team wouldn't have been needed for much. The hitman enters the hotel room, wounds the policeman, then shoots the target with one shotgun blast to his upper left shoulder area. Any hitman worth his fee knows that this is not likely to be an immediately fatal wound. The hitman had a pump shotgun and should have finished the job right then and there. Surely he had more than two shells. Instead, he sees the target is slumped unconscious, then leaves the hotel room without checking to see that his victim really is dead. Nothing seems to be immediately threatening the hit team, though. The hitman spends the rest of his life trying to finish his job and pays the ultimate price for being lazy.
Plot hole: One of Snape's memories show Lily telling baby Harry to be safe, be strong. That had to have occurred before Voldemort killed Lily. Snape was not in the house until after Lily was killed and Voldemort was gone. Only Lily and Harry should have had that memory, but not Snape.
Plot hole: In all scenes where special or heavy items are used against the sixers, they are 'zeroed' in waves or circles. This can be seen by their stations turning red in clusters. This makes no sense as the stations have fixed positions, meaning that the sixers would have identical positions in the Oasis and have no freedom or own will to move relative to each other.
Suggested correction: From a military point of view it makes perfect sense. AOE weapons would be most likely to hit members of the same squads, companies or battalions. It would make sense for squad mates in the oasis to stick together in stations as well. I just watched that scene. As long as the Sixers are trained soldiers or players it makes perfect sense.
Plot hole: Scar tells the pack he didn't make it to the gorge in time to help Mufasa. However Zazu was with them at at the gorge. He could have easily told Sarabi or any of the other lions on the numerous times he spoke with them, exposing Scar.
Suggested correction: Actually, Zazu wouldn't honestly say that Scar was lying; he left Scar at the gorge, but for all he knows, when Scar talks about not getting to the gorge in time, Scar could just mean that he couldn't find a safe path into the gorge to help Mufasa and Simba escape.
Suggested correction: Zazu wasn't with them when Scar said so. He was with Rafiki. He couldn't have heard what Scar was saying.
Suggested correction: But it wouldn't have confirmed that he killed Mufasa.
It would prove that Scar (who had the most to gain from Mufasa and Simba's deaths) was lying about the circumstances surrounding their deaths. But no-one brings it up.
It would prove Scar is lying about the events of Mufasa's (and Simba's presumed) death, and given Scar gained the most from it, the other animals should be extremely suspicious of him.
Plot hole: When Leo, Gustav and Himmel are driving through Miami looking for Pest, Gustav notices that the tracking device that was put in Pest's underwear shorted out because of how much he was sweating. An earlier scene showed that Pest jumped off a boat in the middle of the ocean and swam to Miami. Since the tracking device was in Pest's underwear the whole time, it should have shorted out the moment he jumped into the water leaving Pest safe and Leo, Himmel and Gustav driving around aimlessly.
Plot hole: The opaque red lined map that Otomo retrieves from his first fight is ridiculous. Why would people who know where the hidden base is be carrying around a map on them (which shows a route so basic that they'd have to be brain-dead not to be able to remember it anyway) just so that conveniently one of their enemies can get it?
