The movie was shot entirely in Scotland, especially Edinburgh, but one shot - the opening scene where the camera flies over the city - is Chicago. In the story, detective Dan Lawson is from Chicago and flies to Scotland to investigate a crime. Therefore, the choice of locations is justified by the plot.
