Because Peter Sellers was dealing with a divorce dispute and could not leave the UK, Kubrick chose to shoot the film at the Shepperton Studios in London. The crew set up the Pentagon’s war room, the B-52 bomber, and Ripper’s offices and corridors in the three main studios of the studio. The film’s art direction is Ken Adam, who has just completed "Dr. No". When designing the war room, Kubrick was very optimistic about the double-layered set design plan at first, but then changed his original intention. Adam immediately completed the expressionist set that finally appeared in the film. The entire concrete room is 130 feet long and 100 feet wide. , 35 feet high, it is like a triangular air-raid shelter. In addition to the huge strategic map on the wall, there is also a large round table that looks like a card table in the center of the room. Although the film is black and white, Kubrick still insists on putting a green countertop on the table, so that the actors can We feel more deeply that they are participating in a dangerous game of playing with the fate of the world.
Since the Pentagon was not able to assist, and the B-52 bomber was a cutting-edge weapon that was not allowed to be visited at the time, the set designer could only refer to the cabin structure of the B-29 bomber and the photos of the cockpit of the B-52 to create the film. Inside the cabin, when the set was completed, the invited Air Force officials were full of praise for the accuracy of the cabin. It is said that even the black box is not bad. Kubrick was deeply disturbed by this. He doubted the legality of Ken Adam's research work, lest the sensitive FBI would investigate the matter.
