As the British Board of Film Classification publishes its new guidelines, Ellen E Jones and Mark Kermode delve into the long, chequered history of film censorship and classification in the UK.

Mark speaks to BBFC President (and original Strictly Come Dancing winner) Natasha Kaplinsky about her role, and about her reaction to the new guidelines. And he discusses the Board's controversial history, and some of its most notorious decisions, with ex-BBFC Head of Compliance Craig Lapper.

Ellen talks to director Prano Bailey-Bond about her debut film Censor, which was inspired by the 'video nasty' moral panic of the 1980s. And pop culture critic Kayleigh Donaldson talks her through some of the differences between the BBFC and its US equivalent, the MPA Ratings Board.
