I found yet another interesting WWII film that I thought you all may enjoy. London Can Take It! is a 1940 propaganda film made specifically for an American audience.
Director Humphrey Jenning also made a 20 minute film in 1942 about life during the war titled Listen to Britain. I've never heard of this film, but apparently it is extremely good and was nominated for an Oscar. Has anyone seen it?
