The document discusses choosing a target audience and age rating for a new thriller film called "Psychosis". It decides on a 15 rating to attract a wide audience, as 64% of UK cinema goers are aged 7-34, and 15-rated films have the highest number of releases and box office earnings. A 18-rating would restrict many potential viewers. The content of "Psychosis" fits best under a 15 rating to balance appropriate themes and maximum audience reach.
