This features quite an effective use of archive to bolster US public awareness of the risk of idle talk. Using a variety of social scenarios, we put some “I’ve heard” or “I’ve read” sentences in the mouths of those in the shops, the hairdressers and the bars and then attempt to counter these speculative gossips with some facts and then some out and out propaganda about the superiority of the American soldier, kit and technology against not just the Japanese, but the Nazis too. On that last front, it does recognise that the  USA is not the only nation fighting here, but as this is essentially designed to boost domestic morale and encourage people to keep their traps shut, it’s largely a celebration of the might of a military and the strength of a democracy that will prevail, no matter what. There is some original photography here, but if you’ve followed the approach newsreel cinema took to World War II in any depth, then you will have seen most of that before. The commentary is far too earnest, and the more I watched this I wanted someone sarcastic and caustic - like Pete Smith - to make the point a little more engagingly and less like it was a school lecture, but in 1942 it probably served it’s purpose.
