Factual error: Part-way into the movie there is a scene where Ivan Cooper is walking up the road towards a crowd of people. On the road between him and the crowd are speed cushions, (a traffic calming feature to slow vehicles down). Back in 1972 speed cushions did not exist, they are an invention from the early 1990's.

Factual error: In various shots throughout the film "Sky TV" style satellite dishes can be seen on houses - the film is set in 1972 many years before satellite TV existed.
