Factual error: The movie starts in 1985, jumps '5 years later' and then back to Sasha Luss, then '3 years earlier'. So, in her crusty apartment in an impoverished neighbourhood of 1987 Soviet Russia, Anna is filling a form on her laptop computer.
Factual error: The movie starts in 1985. In the first arresting scene, one of the American spies is using a flip mobile phone.
Factual error: USB wasn't invented until 1995, and flash drives were not available until at least sometime after the year 2000. Anna is plugging a USB flash drive into a fairly modern laptop toward the end of the movie.
Factual error: The car that hits the Soviet mole at the American embassy in the beginning of the movie is a 2019 G class Mercedes but the movie is set in the 1980s. (00:02:45)
Suggested correction: The G class exists since 1979, and it is not the 2019 model and not the 2012 model due to missing LED daydrive lights. Even the bullbar on the front is an very old one, a grill-like cover for the front and lights. Beside that you can not verify if it's a 1980 model or 1995 or 2001.
Factual error: The car chase in Moscow is in a S class Mercedes (W 140) that was a model 1991 (or later) but the scene is set in 1987. (00:20:26 - 00:26:03)
Suggested correction: This is actually not the S class, it is the E class (W124) as you can identify it based on the dashboard. The W124 was build from 1984 till 1995. Found some for sale built around then.
