The BBFC guidelines are used to classify films based on their content such as violence, language, sexual content and drug use. This determines the age rating of films to ensure appropriate content is available for different age groups. Films are examined prior to release and rated accordingly to provide consumers information on the film's contents. The guidelines specify restrictions on different types of content based on the age rating, with more restrictive limits on content deemed unsuitable for younger viewers such as discriminatory language, realistic portrayals of dangerous behavior, strong language, nudity, sexual behavior and violence.
