The second of a two-part documentary about the history of British film censorship looks at the films that have faced problems since the 1970s, a decade in which there were storms over "A Clockwork Orange," "Last Tango in Paris" and "The Exorcist." Film-makers including Bernardo Bertolucci, Oliver Stone and Steve Woolley talk about their battles with the censors over sex and violence. Plus an examination of the video-nasty panic of the mid-eighties, which brought statutory censorship to Britain for the first time, and a look to the future in the age of the Internet.
