duck and cover

Duck and Cover was a social guidance film produced in 1951 by the United States federal government's Civil Defense branch shortly after the Soviet Union began nuclear testing. Written by Raymond J. Mauer and directed by Anthony Rizzo of Archer Productions and made with the help of schoolchildren from New York City and Astoria, New York, it was shown in schools as the cornerstone of the government's "duck and cover" public awareness campaign. The movie states that nuclear war could happen at any time without warning, and U.S. citizens should keep this constantly in mind and be ever ready.
