This movie starts well, with a trip round the offices of a film distribution company that is the spies' "cover", and the shabby bedroom opposite with two chaps filming anyone who comes or goes, with a rifle in case they really have to shoot anybody. Nigel Patrick and Jeffrey Hunter are good actors. I love b/w movies made and set during WWII and just after, but a kind of rot set in. Slightly relaxed censorship meant that Patrick and Hunter constantly make smirking references to the female characters - there are almost wolf whistles on the sound track. I gather that Hunter and Duringer's later affair is no-holds-barred. But this put me off watching any further. I was also turned off by the inability of the designers to even attempt 40s style. I suppose that by the late 50s wartime fashions seemed utterly frumpy, and no actress would have the long hair necessary for the elaborate styles.
