Book excerpt: British Social Realism details and explores the rich tradition of social realism in British cinema from its beginnings in the documentary movement of the 1930s to its more stylistically eclectic and generically hybrid contemporary forms. Samantha Lay examines the movements, moments and cycles of British social realist texts through a detailed consideration of practice, politics, form, style and content, using case studies of key texts including Listen to Britain, Saturday Night and Sunday Morning, Letter to Brezhnev, and Nil by Mouth. In discussing the work of many prominent realist filmmakers, the book considers the challenges for social realist film practice and production in Britain, now and in the future.
