Best movie mistakes of 2015
Factual error: Twice in the film it is made clear that the Pym particle works by reducing the space between atoms in order to shrink an object, and by increasing it to enlarge them. This means that the object will weigh the same, whether shrunk or enlarged - it cannot be otherwise. A 90kg man the size of an ant would punch a hole through any surface upon which he stood (and couldn't ride ants), Doctor Pym has been walking about with a 60 tonne tank in his pocket, Darren Cross lifts a full grown sheep between finger and thumb, and the supersized Thomas The Tank Engine would be far too light to crush the police car (in fact it would float harmlessly away as it would probably weigh less than the air it displaced).
Continuity mistake: There are missing boys along the movie: At the end of The Maze Runner, there are 8 boys that get out of the maze besides Teresa. At the beginning of Scorch Trials, only 7 get in the compound. When Thomas shows the stolen card to the others, there are 6 of them and they all escape with Teresa and Aris. When they get out the mall and enter the city, there are 5 of them besides Aris and Teresa.
Factual error: After Watney patches the blow out of one of the HAB's airlocks with plastic sheeting, tie down straps, and duct tape, he pressurizes the HAB and the plastic sheeting pushes out like an inflated balloon. Assuming the plastic and duct tape would hold this is correct, however the plastic would be much more taut given the pressure difference inside and outside. The real mistake is later in the scene during a sand storm the plastic flops in and out. The plastic would remain tautly inflated, since the inside pressure is much greater than outside, and since the HAB is airtight the storm would have no equalizing effect to cause the plastic to be sucked inward.
Factual error: When the house explodes there is a massive explosion and fireball that creates a pressure wave strong enough to send Brian flying into the van. However not a single window breaks on the houses just feet from the explosion.
Revealing mistake: Inside Jurassic World's main control room, Chris Pratt looks at a view screen depicting a paramilitary team tracking down the escaped I-Rex. In an homage to the film Aliens, the screen is complete with POV cam footage and heart rate monitors. Unfortunately, the FX team didn't catch the fact that all four people are shown having identical heart rates. Ridley Scott made the same mistake in Prometheus.
Continuity mistake: After Rey's lightsaber battle with Kylo Ren, when the Falcon appears in the wideshot Rey's head is turned to look at the Falcon behind her, to her left, with Finn to her right, but in Rey's two closeups - before and after that wideshot, she's looking straight ahead at the Falcon, with Finn lying directly in front of her.
Continuity mistake: When Anastasia returns home with the contract in her hand, she enters her flat and the computer guy is just finishing fixing her laptop. During this scene her brown leather jacket disappears, but she is still holding the contract in her hand - this is a continuous scene with no time for her to remove the jacket.
Factual error: At the beginning, the film is set in 1995 only for a brief few minutes. Then, it goes on to say "15 years later." This brings us to 2010. In 2010, the latest iPhone was the 4. However, throughout this film, nearly every iPhone shown (quite a few) appears to be an iPhone 5s. This is obvious by the rectangular body with fingerprint sensor. In addition, in some places the latest iPads are used, the iPad Air 2 and the iPad mini 3 - These were released in 2013 and beyond. Finally, although I am not 100% sure, towards the end of the film as the woman steps in to the car for the final time on the hill next to the boat, it appears she is wearing a gold Apple Watch or other smart-watch which was released later than 2010.
Continuity mistake: In the scene near the end of the movie where the kidnapped father overpowers one of the bad guys and grabs his gun, he shoots out the front tire of the truck and he and Justin go running away. In the very next scene, Tyler and his buddy jump in the truck to chase the father and son and the tire on the truck is miraculously fixed and inflated.
Factual error: In the film, the San Andreas fault produces the largest, most sensational earthquake in earth history that levels both Los Angeles and San Francisco, also creating a massive tsunami that also floods the latter. In reality, and according to many earthquake experts, the biggest quake that this fault could produce is an 8.3 and, being a land and not ocean fault, cannot cause a tsunami. Or as consultant to the film Tom Jordan, director of the Southern California Earthquake Center stated, "I gave (the filmmakers) free advice, some of which they took... But much of which they didn't - magnitude nines are too big for the San Andreas, and it can't produce a big tsunami."
Factual error: The main character from the video game "Paperboy" is among the alien invaders in the final battle; since that game was first released in 1984, he shouldn't be there, because the probe the aliens received featuring video game footage was launched into space in 1982.
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."
