The BBFC classifies films in the UK according to their content and assigns age ratings to help audiences determine if a film is appropriate for them to view. Films featuring strong language, violence, sexual content or other adult themes receive higher ratings like 15 or 18, meaning younger viewers are not permitted to see them. Thrillers and horror films usually receive a 15 rating due to their potential for menace, threat, or gory images, though some psychological thrillers with less intense content may be rated 12A to allow for a broader audience. Filmmakers aim for lower ratings when possible to maximize profits from a wider eligible viewer base.
