A Day Called 'X'

A Day Called 'X' is a 1957 documentary film narrated by Glenn Ford, produced by CBS in cooperation with the Federal Civil Defense Administration (FCDA) to depict a simulated nuclear attack on Portland, Oregon. Because the film was produced in collaboration with a federal agency (FCDA) for civil defense training and public information purposes, it is frequently classified as a work of the US Federal Government, which places it in the public domain under 17 USC § 105. Even if treated as a commercial production by CBS, the film was released during the 1928–1963 window, which required a copyright renewal in the 28th year to maintain protection. A search of the Stanford Copyright Renewal Database and the Library of Congress Catalog of Copyright Entries (CCE) shows no renewal registration for this title or for the specific episode of the series 'Special Report' under which it might have been filed. The film is widely distributed by the National Archives and Records Administration (NARA) and is available on the Internet Archive without restriction, further confirming its status as public domain.
