Book excerpt: The Insiders' Guide to Factual Filmmaking is an accessible and comprehensive 'how to' guide about the craft of making documentaries for TV, online or social media. Filmmaker Tony Stark distils a long career at the BBC and as an independent producer to explain the conceptual, visual, editorial and organisational skills needed to make impactful and stylish factual films. Interviews with top industry professionals in the UK and US - commissioners, executive producers, filmmakers, strand editors and media lawyers - add valuable insight and authority to this book. For more experienced filmmakers The Insiders' Guide tells you how to get the green light for undercover investigations, how to tell film stories online and on social media, and how to budget a factual film. This is a key text for anyone who wants to succeed in the rapidly changing, competitive freelance markets in Britain and America. It provides expert guidance to students on filmmaking courses, journalists wanting to move from print to video and non-professionals with an interest in film-making. Whatever the final destination of your film - and whatever the budget - The Insiders' Guide provides a vital roadmap. The book's accompanying website is a 'show-me' resource for new directors: with 24 specially-shot film clips illustrating the key rules of filmic grammar and sequence shooting - together with downloadable versions of essential production forms.
