Factual error: Eddie specifically tells the gang not to take his mom's "Delicious Deals" snacks because his mom loves them. But Delicious Deals are made by Mrs. Freshley, a company that was not founded until 1994. The boxes used in the movie even include the modern design that can be found today in most Dollar Tree stores. (00:23:00)
Factual error: How would the creature be able to re-enter the ship by climbing into the reactor piping? The reactor fuel system is not open to the living space of the International Space Station.
Factual error: Mr. Butler called the school that Lucas previously attended and was able to acquire contact information for a former teacher (who longer worked at that school). This type of information is not given out.

Factual error: When the astronaut is being questioned by a 3-star general, he keeps referring to the officer as "colonel", in fact the closed captioning does the same.
Factual error: Following the blowout, Sara's phone is shown several times as being connected to Wi-Fi with a full Wi-Fi signal. Being in the middle of nowhere, surrounded by hills, it's highly unlikely there would be a public Wi-Fi connection for her to connect to.
Factual error: The depiction of lasers is completely off in the movie. While surgical laser is indeed a real thing, such a highly concentrated beam with enormous cutting power seen in the film would take industrial size instruments and an extremely high power supply. Also, a laser beam simply doesn't look that way. Those scenes are way off into science fiction for an otherwise raw and realistic-looking thriller.
Factual error: One of the deaths involves a burning candle, a car and a leaking fuel tank, resulting in an explosion. This wouldn't happen. Multiple independent test evidence that petrol/gasoline can't be ignited this way, a flame isn't hot enough. Only the fumes can be ignited, which isn't what happens here, and the tank wouldn't explode anyway.
Factual error: When the bank robbers pull the money out of the vault, they claim all the cash is from 1982. Yet most of the bills have large faces, which was introduced into rotation in 1996.
