Factual error: When Amy is fired from S'Nuff magazine she takes her story on Aaron Connors to Vanity Fair, who run with it. That is not going to happen. Amy wrote the article while a paid employee of S'Nuff magazine and that means the copyright in the article (and, very relevant to this issue, the photographs of Aaron they paid to have taken), resides with them, not with her. It isn't hers to sell. No magazine editor of any standing is going to buy an unsolicited article without checking its provenance backwards and forwards, and that would mean checking with Amy's previous employers - after all, what would happen if they changed their minds and ran the story themselves?
Continuity mistake: Ellis leaves in in his dad's Jeep (model year 2005-2007) and in the very next scene he is driving a newer model.
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).
Factual error: Towards the end of the film, Solomon is trapped in a small Plexiglas box and fires his gun into the bulletproof sides numerous times, but the bullets don't ricochet or get embedded in the glass.
Continuity mistake: After Rey touches Luke's lightsaber she begins to have the vision, and when she falls to the floor the blaster is missing from the back of her belt, but after she "sees" Luke and R2 and then stands up the blaster is back again, tucked into her belt (even though Rey's having her vision of things all around her, she herself is not a vision).
Continuity mistake: There are missing boys in 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. The last boy (called 'Jack' by cast and crew) dies in a deleted scene, the other two boys simply vanish without a trace or explanation.
Factual error: On the bus ride in Nepal, they're playing a Hindi song from an Indian movie (Kabhi Khushiyan Kabhi Gham) that was released in 2001. The time frame on the bus is 1996.
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.
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.
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. (00:44:00)
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."
