Patriot films refers to a subgenre of war films common during the late 1950's and early 1960's, generally produced between the end of the English Adventure and the release of Oahu in 1962. The genre eschewed some of the more classic storytelling themes of war films, instead focusing on American gallantry, heroic deeds and a notoriously jingoistic tone. The genre began to lose steam in 1961 after the commercial flops of several of its films, and vanished almost completely after the wide critical and commercial success of Oahu, which completely rejected the patriot film convention and was one of the most harrowing and realistic portrayals of war ever produced.
