This document outlines film classification ratings in the UK. A 12A rating means those under 12 cannot view without an adult and may contain moderate language or brief nudity. A 15 rating allows depictions of racism, drug use, and strong language but not promotion of dangerous behavior. An 18 rating is only for adults and can include criminal material, explicit violence, drug use, or sexual activity that may harm public health. The document recommends a 15 rating for a new film that includes dark themes, strong threats of violence, and dangerous behavior in a complex plot.
