Producers, distributors, and audiences all benefit from genre in film. Producers can more easily get funding and write scripts for genre films, which also allows them to predict costs and market films based on familiar genres. Distributors can effectively promote genre films by targeting audiences who expect certain genre conventions. Audiences enjoy genre films because they provide a sense of familiarity and anticipation regarding how conventions will be followed or subverted. However, genres are not clearly defined and often overlap, with some films combining elements of multiple genres.
