This document discusses genres in film and their relationship to producers, audiences, and ideology. It notes that genres use sets of conventions across aspects of filmmaking like cinematography, editing, and narrative. Producers find genres instantly marketable as they can draw from pools of talent and resources, while audiences find genres useful for distinguishing film types and personal preferences. The document then discusses how genres can reflect and shape societal ideology, with action movie characters often featuring stereotypical male heroes, love interests, and villains, and narratives starting with an event or thing at risk that is resolved through approved violence and a return to normalcy.
