This project aims to increase knowledge and understanding of the contemporary feature-length documentary film industry in the UK. It has three core objectives: 1) to map the industry and analyse its operation; 2) to historicise the industry's formation and the factors that have shaped its development; and 3) to investigate the criticisms and challenges the industry faces and explore how these might be addressed. Documentary has formed a major part of British film culture ever since John Grierson, the figurehead of the British Documentary Movement (1926-46), coined the term in 1926. However, with so much British scholarship focusing on that period and its achievements, subsequent developments have been marginalised. One of those developments has been the emergence of a feature documentary industry comprised of organisations dedicated to the production of feature-length (70 minutes or more) films for broadcast or theatrical exhibition that is distinct from - albeit often related to - factual or specialist factual television production). Since the beginning of the 21st century, feature-length documentaries have experienced a major upsurge in popularity and become a significant global box-office attraction. Although this is most obviously evidenced by US films such as Farenheit 9/11 (2004) or An Inconvenient Truth (2006), a range of UK feature documentaries have enjoyed significant (critical if not necessarily commercial) success, including Black Gold (2005), The End of the Line (2008), Selfmade (2010), Up in Smoke (2011), the Oscar-nominated The Act of Killing (2012), and the Oscar-winning Citizen Four (2014). As a result, the UK feature documentary industry is now an established part of the broader film and television industries, with distinct subsectors dedicated to finance, production, distribution and exhibition. Yet despite its established presence, and the fact that UK documentary is widely acknowledged to be experiencing a 'golden age' (Sight & Sound, September 2014, p. 52), little scholarly attention has been paid to the industrial structures underpinning it. There is thus a timely and urgent need to study the UK documentary industry if its current economic and cultural success is to be understood, supported and sustained. This project has been developed in association with three institutional partners - the British Film Institute (BFI), Creative England and The Grierson - as well as five partners from each of the industry's main subsectors (finance, production, distribution and exhibition): The BRITDOC Foundation is the leading broker of documentary film finance and distribution in the UK; Dartmouth Films is one of the UK's most influential documentary production companies; Dogwoof is the UK's leading documentary distributor; Sheffield Doc/Fest is the preeminent documentary film festival in the UK; and Yaddo, the UK's first documentary webcaster, was launched in 2016 by the former head of BBC Storyville, the UK's leading broadcast platform. All partners will participate in the research via a series of semi-structured interviews, while the partners from the industry's subsectors will also take part in a period of Participant Observation. Combined with desk-based analyses of primary and secondary materials (academic literature, trade press, close analysis of the films themselves), this comprehensive methodology will best enable the three core objectives to be addressed. The project will have a number of tangible applications and benefits to the industry in addition to the range of academic outputs it will generate. The policy proposals will provide the BFI and Creative England with evidence-based, practically-applicable recommendations. Together with the Doc/Fest workshops and project website, these will facilitate knowledge exchange between academia and industry that will expand understanding and work towards a more sustainable, innovative and culturally and economically successful documentary industry.
