In David Attenborough’s short trailer he demonstrates how to launch an argument and sell in documentary in just a few powerful seconds. If you’ve done the Copycourse you’ll recognise the structure he uses a mile off.

David Attenborough: I am David Attenborough and I am 93. I ‘ve had the most extraordinary life. It’s only now that I appreciate how extraordinary. The living world is a unique and spectacular Marvel. Yet the way we humans live on earth is sending it into a decline. Human beings have over run over the world. We are replacing the wild with the tame.

This film is my witness statement about my vision for the future. The story about how we came to make this, our greatest mistake. How if we act now we can yet to put it right. Our planet is heading for disaster. You need to learn how to work rather nature rather than against it. And I’m going to tell you how. In cinemas 2020.
