Case studies

Welcome to the BBFC case studies. Written by BBFC staff, our case studies explore why a film has a particular age rating, if it was cut, or even banned.

Please note that all our case studies and 'From the archive' files are subject to copyright and may not be reproduced or transmitted in any form (electronic, photocopying, recording, or otherwise,) without prior written permission from the BBFC.  You should email us if you wish to reproduce any of these materials.

Our film case studies tell you why we made certain decisions and offer background information that you won’t find anywhere else. Find out why some films and their BBFC age rating were discussed in the news media, what films received complaints about their age rating, and which were praised.

Some case studies are for films you will definitely have heard of, like A Clockwork Orange. Others like Freaks are lesser known but important films. Some are films like Juno and Fight Club that you might know of but weren’t aware they caused a stir when submitted to the BBFC. We provide case studies for all films we introduce as part of our longstanding relationship with IntoFilm. We no longer classify video games but there are some video games case studies which offer a historical view of how we classified some well-known video games.

We regularly update our case studies, and add new titles several times a year. We welcome suggestions for new case studies, but, as each one takes a while to research and write, we prioritise requests.You can email us to suggest a Case Study.

If you are researching a specific title and would like access to the BBFC's paper file archive this may be possible depending on the age of the work. You can request access to our archive in Education resources.

Based on Suetonius's Lives of the 12 Caesars, Caligula had been creating legal difficulties and controversy long before it was submitted to the BBFC for classification.

Cannibal Holocaust

Genre: Drama, Horror

This 1979 Italian cannibal horror film was not submitted to the BBFC at the time of its original production, presumably because no distributor felt that it was likely to be acceptable for classification at that time. Instead, a version of the film that had already been slightly pre-cut by its...

Genre: Horror

Cloverfield was first seen by BBFC examiners in an unfinished state, for advice as to its likely classification category. An advice screening is a facility offered by the BBFC to distributors.


Genre: Animation, Children, Fantasy

While adults might pay for a cinema ticket to endure strong, bloody, gory horror of films such as Saw and Hostel, they aren’t the only audience for horror at the cinema. Films aimed at children have their fair share of scary moments, and always have. So how does the BBFC treat horror aimed at...

David Cronenberg's film of J G Ballard's controversial 1973 novel had already aroused comment in the press before it was submitted to the BBFC. Its screening at the 1996 Cannes Film Festival had provoked the Evening Standard's film critic, the late Alexander Walker, to describe the film as 'beyond...
