Plot hole: When Tim takes his sister Kit Kat back in time, she gets a sudden brain change as she realises she's now going out with his friend and finds him attractive in the changed timeline. However, Tim has no idea anything's different in his life until he gets home and discovers his daughter has become a son.
Plot hole: Throughout the entire movie, barns, houses, cars, 18-wheelers, etc. are demolished and lifted into the air like they were made of paper. And yet Jo and Bill pass through one tornado after another with nothing more than their hair getting messed up a little. You'd think the debris alone flying into their faces at 100 miles an hour would be enough to give them a few injuries.
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: When the castle is about to blast off, Brad and Janet abandon Dr. Scott's wheelchair at the door of the castle and carry/drag him across the porch and down the steps. After the blast off, Brad, Janet, and Dr. Scott are on the grass and have been blown some distance apart from each other (in the UK version, there's another song where Brad and Janet crawl toward Dr. Scott so they are blown farther apart than shown in the US version). It seems extremely unlikely that the remains of Dr. Scott's wheelchair just happened to fly from the doorway to land directly under him during the blast. Brad and Janet can barely crawl so they didn't move him or it. (01:34:10)
Plot hole: Hiding in a fridge (or anything else) in order to be conveniently blown out of the way by an exploding nuclear device is absurd beyond belief. The fridge is just so much extra reaction mass and would be vaporised by the expanding nuclear explosion - it wouldn't be daintily picked up and thrown a few kilometers to safety. If it was, why doesn't it land in a shower of similar artifacts which have also been dislodged and thrown around? Incidentally, even if it was thrown out of the way as shown, anyone inside it would be turned into a smear of strawberry jam by the acceleration required to beat the shock and heat wave of a nuclear blast, and then liquefied by the deceleration involved in hitting the ground at that speed.
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: Why was $100,000,000 worth of heroin sitting in the police vault all this time before the bad guys stole it? Wouldn't the DEA have taken possession of the drugs long before that?
Plot hole: Barry gets killed violently at the pageant. So obviously there should be blood everywhere. When the police go up to the crime scene, they find nothing. There's no way the killer had time to clean up anything, let alone drag away Barry's body without someone seeing him. And blood starts dripping after the police leave the scene.
Plot hole: In the Cowboys' last possession of the final game, Spike makes a long run before being stopped on the goal line. The Cowboys' next play is a run up the middle. The Little Giants stop the run and the Cowboys lose possession, but since that was the first possession of a new set of downs, the Cowboys would have three more chances to score.
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?
Plot hole: When Charlie sets out to hijack the money train, he jumps off the platform onto the tracks as it arrives, in plain sight of the driver and other passengers at the station, and only puts his mask on once he's in position on the tracks. The train conveniently stops right over top of Charlie, allowing him to enter through the conveniently-placed grate on the train's floor. (01:17:15)
Plot hole: While it is essential to the story, there is a problem with apes in the space ship. While it is the one that took Taylor to the future, there is no way the chimps could have salvaged the ship from the water (plus there wasn't enough time for such a salvage operation. Kira and Cornelius were living in the ape city we see in "Beneath the Planet of the Apes" never mentioning to Brent that they found a spaceship he could travel back with). They didn't have the technology for such an operation, no diving suits, and chimps are scared of water. Also, the water would have destroyed the power systems of the ship when it sank. (00:00:25)
Plot hole: When Greg gets caught faking his summer job, the receptionist tells his father that they don't employ minors, but Heather Hills who is sixteen (we know this because she is about to have her sweet sixteen) is a lifeguard at the pool.
Plot hole: In the end of the film it is heard the police want to exhume the body of Charles Lee Ray from his grave site in New Jersey. Now when Chucky and the crew get to the grave site they find and kill a coroner who is digging up the body. He is the only one there at 1am, by himself, a lonely coroner without any police officers, after all this is a police investigation and I doubt the cops would have him there alone. Then right at the end the Detective who is hunting them arrives. Now he is a cop from Lockport, about six states away. A. Why did he drive all that way to see the body? B. A cop from all the way down there shows up but no new Jersey cops are at the scene?
Plot hole: The first time they communicate with the "entity" in the spaceship, they find a correspondence between numbers sent by the entity and letters of the alphabet. The entity presents itself as "Jerry". Later on, the entity tells Dustin Hoffman, "Stop calling me Jerry" - and then Dustin Hoffman realizes that the number-letter correspondence was wrong, and the actual name of the entity was "Harry". But if that is true, how could they have communicated without problems before? The very first word that the entity used was "hello", which would have to be displayed wrong, since it begins with an "h" and has an "e".
Plot hole: We see Jason get his outfit from Harold's clothes line. Yet in Chris's flashback Jason has these same clothes already on.
Suggested correction: I went and looked at both Chris version of Jason and Jason in the recent Part III. The Part III Jason outfit in Chris version has a lot darker clothes. Same style, just darker. That type of clothing is very similar though.
Plot hole: There is absolutely no point in getting James involved with Layla for Burke. She could have given him the program, why get someone to sabotage his own plan?
