I think people that will find this film interesting, are those who enjoy watching movies in a historical context. Released in 1939, it was one of the earliest movies with a distinct anti-Nazi theme. There is no subtlety here. The film's theme is that there is a vast network of Nazi spies and sympathizers at work to subvert America. The film ignores the the likelihood that there were more, and better organized communists running around, then Nazi supporters. But, the purpose was political, convince Americans that there was a eminent Nazi threat. I suspect in this, the Warner Brothers, succeeded.
