Before the Flood is a 2016 documentary film about climate change directed by Fisher
Stevens. The film was produced by a collaboration between Stevens, Leonardo
DiCaprio, James Packer, Brett Ratner, Trevor Davidoski, and Jennifer Davisson
Killoran. Martin Scorsese is an executive producer.
As revealed by DiCaprio on September 9, 2016 at the Toronto International Film
Festival, the documentary has debuted October 30, 2016 on the National Geographic
Channel. As part of National Geographic's commitment to covering climate change, the
documentary was made widely available and free of charge on various platforms.
The film shows DiCaprio visiting various regions of the globe exploring the impact
of man-made global warming. As a narrator, DiCaprio comments these encounters as
well as archive footages. DiCaprio repeatedly references a 15th-century triptych by
Hieronymus Bosch, The Garden of Earthly Delights, which he uses as an analogy of the
present course of the world toward potential ruin as depicted on its final panel.The
film also documents, in part, the production of DiCaprio's 2015 film The Revenant.
DiCaprio's comments and inquiries focus extensively on climate change denial, mostly
among corporate lobbyists and politicians of the United States
