During the First World War, many films were made about life in the war. Topics included prisoners of war, covert operations, and military training. Both the Central Powers and the Allies produced war documentaries. The films were also used as propaganda in neutral countries like the United States. Among these was a film shot on the Eastern Front by official war photographer to the Central Powers, Albert K. Dawson: "The Battle and Fall of Przemysl" (1915), depicting the Siege of Przemyśl, disastrous for the Austrians, with incidents reenacted using soldiers as extras.
