Examiners from the BBFC give an insight into film classification Using clips from a range of films including Borat, Die Hard 4.0 and Casino Royale, film examiners from the British Board of Film Classification explain how they take difficult decisions about which certificate to award a film. The examiners say they reflect public opinion and, as public opinion changes, they respond with new guidelines. One of the trickiest decisions for the examiners is whether a film should be a 12A or a 15. They look closely at the content of every scene. Four main issues determine the final classification – violence, sex and nudity, taste and decency, and bad language.
