A grown man shouldn't really be discussing a 'Carry On' film, but this has always been my personal favourite; and the series soon went into a precipitous decline after the franchise was taken over by Rank in 1966.
It actually rewards knowledge of classic adventure films of the forties like 'The Maltese Falcon' and 'The Third Man', both referenced by the presence of Eric Pohlmann - since he is referred to as 'The Fat Man' and was actually in 'The Third Man (not to mention having recently voiced Blofeld in 'From Russia with Love'); and has some genuinely witty dialogue (such as "Was it - THEM?" "Well it certainly wasn't - US!!" and "So you knew my father!!"). There's even a little mild satire, such as the Russian-accented cipher clerk played by Gerton (sic) Klauber squinting at an intercepted message as he reads it aloud to the head of MI5, and the sign on their table that greets our heroes in a Viennese restaurant reading 'Reserved for Party of British Agents'.
Cameraman Alan Hume actually graduated to the James Bond series. The opening sequence beginning with Victor Maddern driving up to the north entrance of Pinewood Studios anticipates that of 'Get Smart!', while the finale at STENCH headquarters is well worth the wait. Embellished with atmospheric music from Eric Rogers, presided over by the memorably strange Dr. Crow and staffed by stern henchwomen dressed like Modesty Blaise, (SPOILER COMING:) it obligingly has a prominently displayed panel for blowing the place up like the lever in Frankenstein's laboratory at the end of 'Bride of Frankenstein'.
Richard Wattis did three days work on this; his one and only 'Carry On'. Liz Fraser had sadly just left the series, and her replacement by Barbara Windsor (although playing a genius with a photographic memory) showed the series was coarsening. But Dilys Laye compensates by providing a memorable dragon lady.
