The terms Core and Niche are often used interchangeably and this is a mistake. The niche audience for your film is that slice of the population that has a particular interest in your film or an aspect of your film. The core audience for your film is those people within each niche that are your most ardent supporters. Those people who will spread the word about your film to not only their networks, but to the rest of that niche. You can have multiple niches that are interested in your film, and within each niche there is a core who combined adds up to the core of your film.
