Historical documentaries and historical feature films are collectively referred to as films with the theme of major events in history. Most of the content involves political and military struggles. Because the creation of historical films is based on historical facts, the expression of historical events and historical figures must conform to the historical truth, but the secondary plot and detail description allow a certain degree of artistic fiction.
War movies, also known as "military movies", are movies about major military actions in the history of war. There are two kinds of common war movies. The first is to portray characters, focusing on their ideological character through the description of war events, battle processes and battle scenes.
The other mainly reflects war events, and vividly expounds a major military action, military thought, military principle and strategy and tactics through the description of characters and story plots.
