I used the British Board of Film Classifications website. www.bbfc.co.uk/
The information below is taken from the website about the 15 classification:
Discrimination - The work as a whole must not approve disriminatory language or behaviour.
Drugs - Drug taking may be shown but the film as a whole must not promote or encourage drug misuse. The misuse of easily accessible and highly dangerous substances such as aerosols is likely to be unacceptable.
Horror - Strong threat and menace are permitted unless sadistic or sexualised.
Imitable behaviour - Dangerous behaviour (e.g. self-harming) should not dwell on detail which could be copied.
Language - There may be a frequent use of strong language. The strongest language may be acceptable if it is justified by context. Aggressive or repeated use of strong language may not be accepted.
Nudity and Sex - Nudity may be allowed in a sexual context but without strong detail. Also sexual activity may be portrayed without strong detail. Strong references may not be acceptable unless it is justified by context.
Violence - Violence may be strong but should not dwell on the infliction of pain or injury. Strongest gory images and strong sadistic or sexualised violence are unlikely to be accepted.
Theme - All themes are allowed providing that they are appropriate for 15 year olds
