This page shows you the list charts. By default, the movies are ordered by how many times they have been marked as a favorite. However, you can also sort by other information, such as the total number of times it has been marked as a dislike.
The 'Case Studies' page of the British Board of Film Classification (BBFC) provides detailed accounts of particularly controversial films to help with academic work.
These case studies provide insight into how the BBFC come to their classification decisions about films and explains why the films featured may have been a problem for the board to classify.
This list provides you with every film that has a case-study written on it, many of them considered some of the most controversial movies ever.
