As we can see above, the USA had much better sales than the UK did. I don't believe the film was targeted at a British audience as you can see by the figures there was a bigger sale in the USA where the film was made, with American actors. However, the film is based in a city and a thriller which may then target the niche audience of Brits of the demographics of occupations in the city or a lover of thrillers.
