Factual error: In a few scenes at the hotel by Heathrow Airport, several British Airways aircraft are seen, all with the current paint scheme instead of 1995's.
Factual error: Whilst the autopsy is been shown on international television, Kiev is shown to be in Russia, when in fact Kiev is in the Ukraine.
Factual error: In the scene where Ray is delivering the pirated video tapes to his friend, in the background shots there is a Citroen Xsara Picasso quite visible in the scene. This is a car that was launched in 2000 so wouldn't have been on the streets of London in 1995.
