Plot hole: In Night at the Museum 2, the parts of the tablet that are missing were attached to the gate to the underworld, which implies it was originally attached to that, and those parts were left behind when it was removed. But in this film we see the tablet getting found on the wall in Ahkmenrah's tomb, and the missing parts are left behind on the wall of the tomb.
Plot hole: Sea-Plane tells the group that he has tried twice to cross the canyon and complete the transportation level. It would have made no sense for him to be completing that level moving toward the jaguar if he didn't have the jewel needed to finish the game. Either he had been given a jewel and it was reset back and given to the new players or there could be more than one jewel in the game but he doesn't mention having his own jewel.
Plot hole: While on the boat, Paddington suddenly appears inside the mail sack, thus implying he managed to open the precinct, get inside the sack and find someone who closed the precinct again. An impossible task.
Plot hole: The idea that Ben Gates had to run away despite the President's being okay with the kidnapping does not make sense. The President could simply pardon him if necessary. However, when he ran away, he would likely be committing other crimes (fleeing and eluding police, reckless driving, etc.) that would not be federal crimes and so would not be pardonable.
Suggested correction: That's basically what he did at the end. Even though the President was OK with Ben "kidnapping" him, if Ben didn't find the lost city of gold he would have been arrested and charged for kidnapping the President (amongst other charges). However, because Ben was able to find the city the President gave him and his crew a full pardon and explained that it was a misunderstanding.
Plot hole: Why on earth do they drive the Minis up the ramps into the bus while it is moving? They are on a long, straight, relatively quiet stretch of road, but there are cars and buildings about. That ramp is going to make a noise like the sky coming down (we see sparks as it scrapes on the road) and they put on a display anyone would be, frankly, amazed to see. Don't they think one single person would call the police? Don't they think that reports of three brightly coloured Minis will be connected with the recent robbery? They cannot possibly think they have to load the Minis on the run in order to elude the police; they have lost the police cars and are no longer being pursued. Why not just park the bus on the hard shoulder and drive the Minis sedately up that ramp? An unusual sight, maybe, but nowhere near as clumsy, obvious and attention-getting as the way they do it. They are asking to be pulled over and arrested.
Plot hole: Doyle attends Gondorff's betting shop three times, and he listens to the announcer calling three races from three different race tracks - Narragansett in Rhode Island, Belmont in New York, and Riverside Park in Missouri. He cannot possibly miss the fact that the same announcer calls all three races! J.J. Singleton, the race caller, has an instantly recognisable voice, and Doyle wouldn't be fooled for a second. Each race track would have had its own announcer.
Suggested correction: There are a lot of things Doyle is processing when he's in the shop. There's a lot happening, and he has a lot on his mind, and increasing pressure and stress each time. It's quite possible that he wouldn't notice the accent of the announcer, something he has no reason to doubt.
Rubbish. During his first two visits, he sits quietly listening to the race announcements. On his second visit, he would recognize J.J. Singleton's distinctive voice and would realize something was very wrong.
Plot hole: In the beginning, vampires are shown to be invisible in photos but then they seem to appear in videos like security footage and social media posts.
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: Near the end, when Ice asks to say goodbye to the kids in the hotel room, the kids have on their pajamas, yet their luggage was left on the train earlier in the day. It is unlikely that they would have gone to the train station to get their belongings following the chaos of the Christmas party.
Suggested correction: They have backpacks so their pyjamas were probably in their bags.
In a scene right after the train scene the kids tell the mom that Nick lost their luggage. The mom may have picked up some pyjamas for the kids after learning that they lost their luggage.
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: The newspaper headline showing young Alex being rescued from a crate is dated April 8, 1972. In the next scene, we see young Alex dancing in the Central Park Zoo, and watching him are Marty, Melman and Gloria as baby animals. This makes no sense at all. In the first film, Marty celebrates his tenth birthday. Key word: tenth. It is also known that the scenes of the main characters as adults take place in the present i.e. Alex confessing to breaking Marty's iPod. Seeing how the animals age quicker than humans, Marty, let alone his three friends, would have to have been born in the mid-1990s and the flashback scenes could not have taken place in 1972.
Plot hole: Not far into the movie, Starla decides to check out the basement to see what Grant's been up to. As soon as the door is opened she reels from the stench and we discover that it's full of rotting meat and dead animals. In reality, the whole house would have smelt like an abattoir for days before hand and the stench would have permeated out into the neighbourhood. A non-airtight wooden door would not have kept that kind of smell located to the basement only.
Plot hole: The police Inspector recounts the murders, comparing them to the ten Biblical plagues of Egypt, and he states that in keeping with this theme Dr. Kitaj was killed by rats. First, Dr Kitaj dies in a plane crash. Okay, he was attacked by rats in flight but nobody would know that - his plane crashes in a huge, violent fireball and nobody would find any rat remains after that. Second, there was no plague of rats in ancient Egypt! (Go ahead, look it up). Even if the police had made the connection between the mysterious deaths and the ancient plagues they would not make the connection here.
Plot hole: Captain Smolsky only gets hit in the back with the plaster. So why, later on, is his entire body covered in hardened plaster, like a mummy?
Plot hole: There is no reason for there to be sinks in the bathrooms. The cars may be able to use sinks just as they use toilets, but in the bathrooms they are too small and too inaccessible for any use.
Plot hole: When Butthead pushes Beavis out of Muddy's car, Beavis causes a huge car crash. Then, a few seconds later Butthead falls out and causes cars behind him to crash, but the crash that Beavis started made a barrier along the highway, so how could those cars get behind Butthead so fast? (00:51:50)
Plot hole: As shown when Robin comes under the influence of Slade's mind control device, the hypnotized people retain their abilities and higher intelligence, just with a loyalty to Slade. That being said, when Slade hypnotizes all the DC heroes, Superman and The Flash are among them in the theater. Slade orders all the heroes to chase after and destroy the Teen Titans. The Titans take off on foot with the others running after them and are able to keep their distance in a big chase sequence. Superman and The Flash never use their super speed to over take the Titans, which would have been so very easy.
Plot hole: The premise of the movie is that a group of this man's genetic offspring have united to learn his identity. He receives a stack of the bios of those in the lawsuit. One of the children he visits is severely disabled in a nursing facility and would not have been capable of joining the lawsuit.
