The 11th Hour is a 2007 documentary film, created, produced and narrated by Leonardo DiCaprio, on the state of the natural environment. It was directed by Leila Conners Petersen and Nadia Conners and financed by Adam Lewis and Pierre André Senizergues, and distributed by Warner Independent Pictures.
Its world premiere was at the 2007 60th Annual Cannes Film Festival (May 16–27, 2007) and it was released on August 17, 2007, in the year in which the Fourth Assessment Report of the United Nations global warming panel IPCC was published and about a year after Al Gore's An Inconvenient Truth, another film documentary about global warming.
With contributions from over 50 politicians, scientists, and environmental activists, including former Soviet leader Mikhail Gorbachev, physicist Stephen Hawking, Nobel Prize winner Wangari Maathai, and journalist Armand Betscher, Paul Hawken, the film documents the grave problems facing the planet's life systems. Global warming, deforestation, mass species extinction, and depletion of the oceans' habitats are all addressed. The film's premise is that the future of humanity is in jeopardy.
