The Society for Total Extinction of Non-Conforming Humans (STENCH for short) has grabbed a secret formula and the British Operational Security Headquarters (BOSH in brief) tackles the job of getting back Formula X and outwitting its arch enemy, Doctor Crow. Through shortage of personnel, the assignment is handed to Simkins (Kenneth Williams), an agent in charge of training new spies, and three of his pupils.
Best knockabout sequences take place on the Orient Express, in a Viennese restaurant, a murky quarter of the Casbah and in the Automatum Plant where the inept foursome nearly come to a sticky end, but are rescued by good luck and the intervention of a beautiful spy.
Kenneth Williams’ brand of camp comedy, while very funny in smallish doses, can pall when he has a lengthy chore as here. But Bernard Cribbins brings some useful virility to his fatuous role, Charles Hawtrey contributes his now familiar performance as the guileless one and Barbara Windsor proves a well-upholstered and perky heroine as the girl spy with a photogenic memory.
