War and Anti-War Films often acknowledge the horror and heartbreak of war, letting the actual combat fighting or conflict (against nations or humankind) provide the primary plot or background for the action of the film. Typical elements in the action-oriented war plots include POW camp experiences and escapes, submarine warfare, espionage, personal heroism, "war is hell" brutalities, air dogfights, tough trench/infantry experiences, or male-bonding buddy adventures during wartime. Themes explored in war films include combat, survivor and escape stories, tales of gallant sacrifice and struggle, studies of the futility and inhumanity of battle, the effects of war on society, and intelligent and profound explorations of the moral and human issues.Some war films do balance the soul-searching, tragic consequences and inner turmoil of combatants or characters with action-packed, dramatic spectacles, enthusiastically illustrating the excitement and turmoil of warfare. And some 'war' films concentrate on the homefront rather than on the conflict at the military war-front. But many of them provide decisive criticism of senseless warfare.War films have often been used as 'flag-waving' propaganda to inspire national pride and morale, and to display the nobility of one's own forces while harshly displaying and criticizing the villainy of the enemy, especially during war or in post-war periods. Jingoistic-type war films usually do not represent war realistically in their support of nationalistic interests, while avoiding the reality of the horrors of war. The good guys are portrayed as clashing against the bad guys (often with stereotyped labels such as 'krauts,' 'commies,' 'Huns,' or 'nips'). These revisionistic, politically-correct and historically inaccurate films, in such diverse examples as Sands of Iwo Jima (1949) and The Alamo (1960), would often redefine the facts.War films can also make political statements - unpopular wars (such as the Vietnam War and the Iraq War), have generated both supportive and critical films about the conflict (i.e., Robert Altman's M*A*S*H (1970), Kenneth Branagh's Henry V (1989), and Michael Moore's documentary Fahrenheit 9/11 (2004)).War films are often paired with other genres, such as romance, comedy (black), and suspense-thrillers. A number of war films are actually historical epics, authentic attempts to recreate the experience of war on screen, rather than pure war films. Some are actually westerns masquerading as war films.This genre has existed since the earliest years of cinematic production in the silent era. Film-makers have been provided ample opportunities for material from American history, stretching from the French and Indian Wars to the Vietnam War. In particular, the many wars of the 20th century (primarily the First and Second World Wars, but also subsequent wars) have provided rich material for film makers. War films as a major film genre emerged after the outbreak of World War I.
