Overview
Department S is a British spy-fi adventure series, produced by ITC Entertainment. It consists of 28 episodes which originally aired in 1969 and 1970. It stars Peter Wyngarde as author Jason King (later featured in spin-off series Jason King), Joel Fabiani as Stewart Sullivan, and Rosemary Nicols as computer expert Annabelle Hurst. These three are agents for a fictional special department (the "S" of the title) of Interpol. The head of Department S is Sir Curtis Seretse (Dennis Alaba Peters).
Production
"When a case proves too baffling for the minds of Interpol, they turn to the talents of Department S." – from the ITC trailer for the series.
The series was created by Dennis Spooner and Monty Berman, although neither wrote any of the episodes, which were instead scripted by ITC regulars such as Terry Nation and Philip Broadley. Many of the directors on the show had also worked on other ITC shows such as The Saint, Danger Man and Randall and Hopkirk (Deceased).
The series was shot on 35mm film and designed, like all ITC's film productions, to fit the United States commercial format. Although episodes begin with a cold open (after the 'S' logo is shown), unusually, the episode title, writer and director credits appear on screen before the opening title sequence, though after the theme tune has started. With a few exceptions, the principal cast is always studio-bound. Some exteriors are represented by studio buildings, while the rest are mainly shown in second-unit footage using doubles where necessary. Outside locations were, in common with similar series, largely restricted to the Hertfordshire countryside in the vicinity of Borehamwood. At least one foreign location was used, featuring Peter Wyngarde on the streets of Vienna. Otherwise, foreign locations are usually established by the use of stock footage. To further cut costs, the series was produced back-to-back with Randall and Hopkirk (Deceased).
