War Film

War films are a film genre concerned with warfare, usually about naval, air or land battles, sometimes focusing instead on prisoners of war, covert operations, military training or other related subjects. At times war films focus on daily military or civilian life in wartime without depicting battles. Their stories may be fiction, based on history, docudrama, biographical, or even alternate history fiction. John Belton identified four narrative elements of the war film within the context of Hollywood production: a) the suspension of civilian morality during times of war, b) primacy of collective goals over individual motivations, c) rivalry between men in predominantly male groups as well as marginalization and objectification of women, and d) depiction of the reintegration of veterans.
