Mr. Blabbermouth! (1942)

Overview

Following Japan's attack on Pearl Harbor, America was rife with rumors about the size of Japan's armed forces and how well-equipped they were to wage war against the U.S. Using animation, the first part of this film dispels these rumors by showing that the U.S. had more raw materials and more fighting ships. The narrator also cautions moviegoers against spreading rumors (which are often initiated by enemy infiltrators to create fear and dissention) and believing everything they read in the newspapers. Just because "they say" something, that doesn't make it true.
