Factual error: When Chigurh is in the gas station and throws the wrapper on the counter, the "Nutrition Facts" are visible on the label. Set in 1980, the "Nutrition Facts" label wouldn't have been available for at least another fourteen years, as nutrition labels were started in 1994.

Factual error: Near the beginning of the film before James McAvoy heads up to the house for the evening meal, he is seen looking up through a skylight when a Lancaster bomber slowly flies overhead. At the time it was was supposed to be 1935. The Lancaster bomber did not fly until the beginning of 1941. Can't be an Avro Manchester either, they only had two engines and first flew in 1939.

Factual error: During a montage depicting Afghan fighters shooting down Soviet aircraft, the stock military shots show an A6 Intruder, an F4 Phantom, and soon after, an F-16 Falcon getting shot down. All are jets Russia never used, as they are American aircraft. (01:22:15)
Factual error: Firearm issues abound throughout the film. The British detectives (who all seem to be armed, rather than a low proportion of AFO (Authorised Firearms Officers) as in real life) are shown carrying Beretta pistols, even though the Metropolitan Police issue the Glock 17. The SFO (Specialist Firearms Operations) officers are shown carrying MP5 submachineguns, which is accurate, but fitted with cheap toy-shop lasers. Weapons handling is poor throughout, with chickenwing syndrome particularly prevalent. Weapons carriage also appears geared to look "cool" rather than realistic; shoulder holsters - which practically everyone wears in this film - are rarely used for concealed carry in reality.

Factual error: Most of the semi trucks shown in the movie are much newer than 1990, even 1992. One of the trucks that gives Chris a ride has a DOT color-coded inspection sticker in a style that was not around in the early 90's.

Factual error: When Jean-Dominique is taken on a boat ride, a 'Speedferries' vessel can be seen in the background. This company did not commence business until 2004, years after the time in which the story is set and years after Bauby's death in 1997.
