Factual error: Gorillas are strict herbivores. So why does Isabelle eat a rat at the beginning of the film? The serum may have turned her into a crazed killer, as it does with Sebastian, but it hasn't changed the structure of her teeth and palate, biochemistry of her digestive system and so on, all of which would be required. She might kill or torture the rat, but she'd never eat it.
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
Factual error: During the final battle over Area 51, Russell Casse appears in his F-18 and states he is armed. After he attempts to acquire radar lock on the alien's primary weapon, he states he is locked on and has tone. He then says the tactical brevity code Fox-2, which indicates the launch of an infrared-guided missile. However, the missile he is actually attempting to launch is an AIM-54 Phoenix, which is an active radar guided missile, designated by the launch code Fox-3. The master monitor display also incorrectly shows the missile mounted on the port wingtip launcher of the aircraft where the AIM-9 Sidewinder would normally be mounted, instead of on the port wing's weapon pylon where the missile actually is. Historically, the F-14 Tomcat was the only fighter capable of carrying the AIM-54, as it was such a heavy missile; the AIM-54 was never used on the F/A-18. Instead, they carry the AIM-120 AMRAAMs, not the AIM-54 Phoenix that were shown in the film.Stonewall
Factual error: The cavemen Harrier pilots are shown using the hover mode frequently. Harriers, even with drop tanks as depicted in the film, can hover for at most 5-10 minutes, as the thrust required to keep the aircraft in the air without any lift consumes massive amounts of fuel and overheats the engine, and real-life Harrier pilots are instructed never to hover for long periods of time, unless absolutely necessary. The amount of time the cavemen spent hovering (hiding out of sight in a parking garage, sneaking up on the Psychlo gunships, etc.) would have easily caused their fuel to run dry.Dom
Factual error: It is barely credible that a young Victorian woman like Elena would even think about wearing a goatskin miniskirt - exposing her legs in those days would be akin to walking about topless nowadays. Even if she did those bright yellow cotton knickers - gleefully visible in the scene in the beehive - are in no way from the 1860s. Her pants are a hundred years ahead of their time.
Factual error: Trevor - a Professor of Geology - boasts about having an article published in Scientific American, and that is not something any scientist would do. Scientific American is looked upon with slight disdain by the scientific community, considered to be a populist crowd pleaser. It is not even peer reviewed. Considering that he has just turned the geological and archaeological worlds on their heads he would have been better off publishing in Journal of Geological Research or Geology, both prestigious professional journals.
Factual error: In the scene where Neo is shot at by the French guy's henchmen, they shoot with different types of guns. 4 of these are submachine guns which would fire 9mm. Another is a M1928 Thompson would fire .45 APC. Lastly there is a Heckler and Koch G36K which would fire the drastically different 5.56x45mm NATO. When Neo stops the bullets, they are all 9mm Parabellum rounds.
Factual error: The ferry splits in half down the middle, enough so the water is flooding in dramatically as the split grows. There is no possible way that the two halves of the ferry could have remained afloat like that. It would have sunk immediately. Then, as Iron Man "welds" the two halves back together, the ferry is afloat at the same waterline as before the incident, certainly not feasible with all the water it took on.Kit Sullivan
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: The geodes occurring in the mantle during the film are impossible in two ways. Firstly, there are no gaps at those depths. The pressure is approximately 3.5 million times surface pressure, and it is not feasible that such structures could form, let alone be maintained. Secondly, the crystals inside the geodes are described as amethysts. Amethysts are a purple variety of quartz, and as any undergrad geology student could tell you, there is no quartz in the mantle, it simply is not stable at such high temperatures.
