“The 11th Hour” is a new feature-length documentary on the extent and gravity of the global environmental crisis and its impact on human life as we know it. The film is produced and narrated by actor Leonardo DiCaprio and includes interviews with Nobel Peace laureate Wangari Maathai, physicist Stephen Hawking, former Soviet President Mikhail Gorbachev and environmentalist Bill McKibben. We play clips from the film and speak to its two co-directors and writers, Nadia Conners and Leila Conners Petersen. [includes rush transcript]
