Sir David Attenborough's extraordinary life and career is celebrated in a new film premiering in theaters in September and on Netflix. Attenborough also offers a stark warning about the destruction to natural habitats and fragile ecosystems he's witnessed across the decades and the devastating impact climate change is having on the planet. The film - created by Silverback Films, the team behind Attenborough's acclaimed "Planet Earth" and "Blue Planet" series, and WWF, the world's leading conservation organisation - was originally supposed to premiere in theaters in April 2020 but had to be postponed because of the pandemic.
