Continuity mistake: As Jackson is dropping his kids off in the limo, it shows all the mosquito bites on their faces. Later that morning, as the family is sitting down at breakfast, the bites have disappeared and don't show up again.
Factual error: Supposedly Charlie Frost was broadcasting his final moments from the highest peak in Yellowstone, some 2,000 feet above sea level. The whole park is at about 6,000 feet elevation or more.
Factual error: While supposedly in the Antonov aircraft, the characters are down in the cargo area. The Antonov does not have a pressurized cargo area, only the topmost area around the cockpit is pressurized.
Factual error: When Adrian is looking at Jackson's license, it shows his first name, last name. As in: JACKSON, CURTIS. Should be last name first, first name last. As in: CURTIS, JACKSON.
Factual error: In the beginning of the film, when they are in India, the scientist says the temperature could reach 100 degrees Fahrenheit. India uses the metric system, not imperial.
Revealing mistake: During the initial collapse sequence when John Cusack is driving the limousine against the tide of the collapse, the limousine ramps off a piece of floor that is collapsing inconsistently. The wheels stop spinning the moment they leave the road.
Other mistake: They go into the world's deepest copper mine to an underground computer office with windows lit from outside.
Suggested correction: That is probably exactly how it would look. Most underground facilities are conventional buildings, trailers, or modular units arranged in a large lighted tunnel or cavern. This is the arrangement in Cheyenne Mountain Complex, the previous U.S. Antarctic base (under the geodesic dome), and for offices and data repositories in salt mines. The buildings have windows, and the caverns are lighted to facilitate movement between buildings.
