The Secret Service broke the pattern of most of the Supermarionation series that preceded it by being set in the present day (most of Anderson's other shows of the 1960s were set in the near or far future). It also made unprecedented use of live action footage, which was blended in with close-ups of the Supermarionated puppets. Where in previous series, live action was limited to closeups of hands or feet, footage of real actors was often used when showing characters from a distance, driving a car.
