The document discusses film ratings by the British Board of Film Classification (BBFC). It states that a 15 rating means those under 15 cannot rent or watch in cinemas, and films may contain violence, nudity, or language if not too graphic. An 18 rating means those under 18 cannot rent or purchase, and contains similar but more extreme themes than a 15 rating. It provides examples of films like 127 Hours rated 15 and Sin City rated 18. Films rated 18 like Seven and Sin City contain very graphic violence not suitable for under-18s. Comparatively, films like Kiss Kiss Bang Bang and Memento rated 15 still have violence but not as graphic or extreme. The document concludes that their film will receive a 15
