In an never seen interview done a few years before his death, filmmaker Sidney Lumet takes us on a tour of his life and work - the powerfully dramatic and wildly entertaining movies that make up the canon of one of the most socially conscious directors in the history of American cinema. The man behind works such as Serpico, Dog Day Afternoon, 12 Angry Men and Network, Lumet reveals, with grace and humor, what matters to him as an artist and as a human being. Shown at Cannes Classics 2015.
