Great WW2 short.A short movie, made for wartime informational / morale-building purposes. Shows how gossip-mongers undermine the morale of the population, spreading false, negative information and other rumours. Debunks many of the rumours of the time, eg US vs Japanese fleet strengths in the Pacific, and rather methodically sets out the argument that the Allies are stronger, militarily and resources-wise, and will thus win the war.Quite well made and very convincing. Some of it is propaganda but much of it is unadulterated fact. The narration and gossip-mongering scenes are pretty good too, and quite funny at times.

This is an amazingly well made propaganda film--one that is backed up with facts and isn't about stirring up the people. In fact, unlike most propaganda, its aim is to CALM the public--to get them to understand the facts and NOT give way to crazy rumors. In essence, this short film demonstrates that propaganda CAN be good, as propaganda consists of an argument meant to sway opinion--and isn't always bad. In particular, the industrial output of the Allied nations is compared to the Axis--showing that victory is all but inevitable (which turned out to be true)."Mr. Blabbermouth" is also effective because in addition to using a lot of facts, it also employs a nice sense of humor when addressing the nay-sayers and people who spread wild rumors. You can't help but laugh AND be a bit inspired and relieved when you see the film.All in all, at the time this came out, there couldn't have been a much better tonic for frightened Americans. Folks WERE falling prey to insane rumors and they needed to relax and understand that the war was winnable--just not immediately. And, to understand the need to keep your head and confront rumor-mongers for the good of the nation. A wonderful little piece of history that seemed very well reasoned and constructed throughout. Well worth seeing.

Wartime or peacetime, the basic idea of this film still applies: "for safety's sake, please engage brain before putting mouth in gear"; and don't assume that the guy you're listening to has followed that rule!As Ray Bolger observed in "The Wizard of Oz" back in 1939, "Some people without brains do an awful lot of talking!" And while such people usually only damage themselves by looking ridiculous in front of people who actually do know something about the subject under discussion, sometimes they do manage to do major damage to others, whether by innocently ruining a reputation over something they've misinterpreted or by "only trying to help!" (case in point on that last: the Mr. Blabbermouth who invited himself along on a camping trip some friends and I had planned--he nearly laced our trail stew with "perfectly harmless wild mushrooms" which my friend D correctly identified as death angel mushrooms and intercepted in the nick of time!)War or no war, Mr. Blabbermouth lives and can be hazardous to your health!

At first glance this seems to be a stereotypical patriotic U.S. WWII film. It is much more than that even when you factor in some of the cringing portrayals of the enemy. If the enemy were as idiotic as they are often portrayed why were they such a problem? This film balances the jingoistic part with a very good message about attitude. Mr. and Mrs. Blabbermouth are the people who always make the worst of a good situation. If there is any good to be found they will bury it. This film tries to give the American public a feel good boost about their situation in the war. It's a morale builder and it works. I know that I would have felt more optimistic after seeing this short in 1942.
