Factual error: The scene where Yuri starts the car with his voice has two mistakes in it. The first one is that to use voice activation in any kind of car you have to push a button to let the car know that you're talking to it and secondly no car manufacturer would make the voice recognition the only way to start the car, there would always also be the option to start the car via a button or with the key simply because of safety reasons.
Suggested correction: I'm fairly sure a billionaire oligarch could afford to pay for a custom job like that considering a pop star from the 2000s paid Ferrari a solid gold engine and a lawnmower.
Other mistake: When Tamara Is trapped in the middle section it's flooding. It is impossible for the middle section to flood before the end section.
Suggested correction: It would make sense that the door is designed to close much faster than it opens as it is a sealing door and needs to close quickly to form a water tight seal.
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.
