One of the films made by Two Cities Films in the 1940s and 1950s, this is a mostly, well-done story of newspaper reporters running into fifth-columnists within their midst in Britain during WW II. The editor of the paper and some other characters say some silly lines, but they can be overlooked. Richard Greene, Valerie Hobson, and Basil Radford star in this predictable spy thriller, showing the realities of bombed out London, although much of it is a background screen projection. The plot brings up the usual "Do we fight back or acquiesce?" wartime debate.
Hobson had played Elizabeth in Bride of Frankenstein with the master B. Karloff in 1935. Greene was Sir Henry Baskerville opposite Basil Rathbone prior to "Unpublished...", and would later play Robin Hood in the British TV series for several years. Two Cities Films was part by the Rank Organization, which made films for many years. The Rank Organization would later be turned into a casino operator, which is still operating as a public company in England. Another interesting tidbit is Hobson's marriage to producer/writer Anthoney Havelock-Allen; she appears to have met and married him in 1939, and made nine films together. Sadly, they divorced in 1952, and she only made a couple more films after that...
