Factual error: In the first frontal shot of Percival's Porsche following Lorraine, virtually every car parked at the side of the road is from after 1989, one of them not even being on sale until 2007. (00:16:10)
Revealing mistake: During the car chase when the car gets hit by the truck and goes into slow motion you can see the roll cage inside the car.
Factual error: A comment is made about Sinead O'Connor's shaved head during the debriefing. She shaved her head for the video of "Nothing compares to you" released in 1990 a year after the fall of the Berlin wall, after the setting of this movie.
Factual error: Lorraine Broughton gets out of her ice bath and drinks vodka while a view of Big Ben and Portcullis House can be seen out the window. Atomic Blonde is set in 1989 and construction on Portcullis House wasn't started until around 1992 .
Factual error: The Porsche 911 that McAvoy drives is a 964 Turbo, which was only available on the market in late 1990/beginning 1991.
Revealing mistake: After Sofia Boutella dies, she blinks in the next scene in the background. (01:33:05)
Factual error: James Faulkner is wearing Tom Ford glasses (James McAvoy too) - Tom Ford as a brand wasn't created until 2006.
Continuity mistake: During the car chase, the 1st car comes up from behind and shoots out the rear window and rear passenger window then falls behind Lorraine's car. She turns and shoots the driver and passenger and the car roll to a rest in the middle of the street. Continuing down the street, the 2nd car appears in front of her. She stops and throws the car in reverse where the 1st car should have been in the middle of the street, but it's gone. (01:20:00)
Factual error: Berlin never had blue subway trains, east or west.
Continuity mistake: In the opening walk to the London meeting she walks by a parked blue MGB GT (reg E55...) twice on different roads, and then it passes her as well.
Factual error: The trench coat worn by David Percival has the collar tabs on the collar. East German trench coats never had collar tabs, only regular uniform jackets.
Factual error: I just don't buy the idea that you can fit an adult male corpse into the front luggage compartment of a Porsche 911. Especially if rigor mortis has set in.
Suggested correction: You not believing something is not an error. Do you have any facts and figures to back up your statement? Have you actually checked the capacity of the front compartment?
