One Day of War (1942)

Original title: День войны

A Soviet documentary chronicling a single day of the Great Patriotic War—June 13, 1942, the 356th day of the conflict. Filmed simultaneously across all fronts and the home front by 160 newsreel cameramen, and edited by Mikhail Slutsky at the Central Studio of Documentary Films, it offers a sweeping portrait of total war. Released in October 1942, the project captured the Soviet struggle against the German invaders in a single, coordinated day of filming.
