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