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).PEDAUNT
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.
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.Sean4000
Continuity mistake: At the end, the blanket wrapped around the baby changes. In the wide shots, the red stripe is near the feet, but in the close up shots, the red stripe is around the body, next to Katniss' hand. And in the wide shot and first close up shot, the baby's right arm is lying on the blanket, but in following shots, the arm is under the blanket without Katniss doing anything.Bishop73
Continuity mistake: At the end, the TV newscaster reports that 150,000 reserve human forces have been activated. But the crawl strip at the bottom of the screen reads "150,000 RESERVED human forces," a different meaning altogether. (01:59:00)
Continuity mistake: In the scene with the fireworks, the Deputy driving the vehicle has his outside mirror knocked off by a firework. You then see the same and only Deputy in the car, in the mirror getting out of the passenger side of the vehicle to confront the misfits. The change isn't due to the reflected image. (00:13:05)
