The Secret Service

The Secret Service

The Secret Service is a 1969 British children's espionage television series, produced by Century 21 / ITC Entertainment for Associated Television, Granada Television, and Southern Television. Created by Gerry and Sylvia Anderson, and produced by David Lane and Reg Hill, it was the eighth and final Century 21 production to feature Supermarionation. Under the direction of Gerry Anderson, who wanted to compensate for the inadequacies of Supermarionation and increase the realism of the format, The Secret Service incorporates footage of live actors for long-distance shots. Father Stanley Unwin, voiced by and resembling the real-life comedian of the same name, is the parish priest of a rural English village. But Unwin is in fact a secret agent for BISHOP, a covert British Intelligence branch that battles international criminal and terrorist threats. Aided by junior operative Matthew Harding, Unwin answers to his London-based superior 'The Bishop', as he would in his public profession.
