A week before the US presidential election, Leonardo DiCaprio’s “Before The Flood” documentary film started airing free-of-charge over the internet to educate the world about Climate Change and to help sway American voters to make an Earth-friendly choice for the next leader of the world’s largest carbon-emitter.

After only 10 days of “Before The Flood’s” Oct. 21 theatre premiere in Los Angeles, California, the 95-minute documentary film was aired over National Geographic Channel and was made available for streaming across the globe through YouTube, iTunes, Amazon, Facebook and Hulu in a bid to move people to action to delay Climate Change.

Directed by American writer Steven Fisher, the film documents the Oscar-winning actor’s interviews with Climate Change resource persons such as exiting US President Barack Obama, Pope Francis, United Nations former Secretary General Ban Ki-Moon, Indian environmentalist Sunita Narain, American diplomat John Kerry and SpaceX founder Elon Musk, among others.

Even before its release date, “Before The Flood” has been nominated for the People’s Choice Award at the Toronto International Film Festival 2016 held September.

Australian philanthropist and businessman James Packer produced the documentary film alongside DiCaprio, Stevens, Jennifer Davidsson Killoran, Brett Ratner and Trevor Davidoski. (Read: Why James Packer really dumped Mariah Carey)
