The film industry spends significant time and money conducting test screenings and market research to understand what audiences want. This helps ensure their films will appeal to target demographics and be financially successful. Research identifies that the target audience for horror films is 15-25 year olds. Distributors use findings from Pearl and Dean research and similar films to determine their audience. Feedback from test screenings is crucial at different stages of production to improve story clarity and make necessary changes. Conducting questionnaires also provides useful feedback about audience preferences to incorporate into films.
