Describes the frenzied, intense world of documentary film-making, tracing its history back to the early pioneers, such as Dziga Vertov and his ground-breaking Man with a Movie Camera. The book deals with the British documentary tradition founded by John Grierson, and discusses the work of American masters such as the Maysles brothers, Frederick Wiseman and D.A. Pennebaker, as well as Europeans such as Marcel Ophuls, Claude Lanzmann, Chris Marker, and Werner Herzog
