This fascinating book from veteran film journalist Ian Haydn Smith, with a foreword from award-winning director Asif Kapadia, explores 100 of the most compelling documentaries, each with the power to radically change our perceptions and challenge the way we see the world.

Every so often a documentary comes along with the power to change the way you think, to share alternative perspectives, to make you furious about injustice or warm your heart.

Contained in this book are documentaries that fulfil these criteria and astound viewers around the world; real-life stories to stop you in your tracks, bring tears to your eyes and put your heart in your mouth.

From Barbara Kopple's Oscar-winning gritty depiction of working class America in Harlan County, USA to James Marsh's breathtaking Man on Wire, from powerful sporting tales such as Touching the Void to stories of true crimes and their repercussions such as Making a Murderer, this book delves deep into how these films were made, what makes them great, and also what other films you might like if you loved these ones.
