The BBFC considers 9 main issues when classifying films: sex scenes, nudity, language, violence, weapons, drugs, horror, racism, and techniques that may harm children. Sex scenes and nudity are classified based on whether they are explicit or implied. Language is classified based on the use of swear words. Violence is considered based on depictions of blood, weapons, and whether violence is glorified. Drugs and racism must not be depicted in a way that glamorizes them. Harmful techniques like suicide cannot be shown. Overall, the BBFC aims to classify films at the appropriate age level based on these various content issues.
