Pictures (BMP) worked with the Hollywood movie studios to produce films that advanced American war aims. According to Elmer Davis, "The easiest way to inject a propaganda idea into most people’s minds is to let it go through the medium of an entertainment picture when they do not realize that they are being propagandized." Successful films depicted the Allied armed forces as valiant "Freedom fighters", and advocated for civilian participation, such as conserving fuel or donating food to troops. By July 1942 OWI administrators realized that the best way to reach American audiences was to present war films in conjunction with feature films. OWI's presence in Hollywood deepened throughout World War II, and by 1943 every major Hollywood studio (except Paramount Pictures) allowed the OWI to examine their film scripts. OWI evaluated whether each film would promote the honor of the Allies' mission. Foreign operations The Overseas Branch enjoyed greater success and less controversy than the Domestic Branch. Abroad, the OWI operated a Psychological Warfare Branch (PWB), which used propaganda to terrorize enemy forces in combat zones, in addition to informing civilian populations in Allied camps. Leaflet warfare gained popularity during World War II and was utilized in regions such as Northern Africa, Italy, Germany, the Philippines, and Japan. For example, in Japan, the OWI printed and dropped over 180 million leaflets, with about 98 million being dropped in the summer months of 1945. Leaflets dropped in Tunisia read: “You Are Surrounded” and “Drowning Is a Nasty Death”. Millions of leaflets dropped in Sicily read: “The time has come for you to decide whether Italians shall die for Mussolini and Hitleror live for Italy and civilization”. OWI also used newspapers and publicized magazines to further American war aims. Magazines distributed to foreign audiences, such as Victory, intended to convey to foreign Allied civilians that American civilians were contributing to the war. Victory showcased America's manufacturing power, and sought to foster an appreciation for the American lifestyle. Aside from the aforementioned publication and production styles of propaganda, the OWI also utilized unconventional propaganda vehicles known as "specialty items." Specific examples of these items include packets of seeds, matchbooks, soap paper, and sewing kits. The packets of seeds had an American flag and a message printed on the outside that identified the donor. Each matchbook was inscribed with the “Four Freedoms” on the inside cover. Soap paper was etched with the message:
