If you are an intelligent human being then you are interested in climate change because it's the most important issue of our time.

I made my first film McLibel independently but only by accident. I tried to get a commission from all the standard TV broadcasters but because they had been sued by McDonald's in the past none of them would commission me so I ended up making it by credit cards and rich boyfriends (I'm joking - about the boyfriends).

Doing nothing about climate change is still a fairly common affliction, even in this day and age. What to do with those people, who are together threatening everybody's existence on this planet? Clearly we don't really think they should be blown up, that's just a joke for the mini-movie, but maybe a little amputating would be a good place to start?

I have always thought that the role of the film-maker is to present the argument persuasively, emotionally and coherently and then it is over to the viewer, they are either convinced or not convinced, moved or not moved and they decide whether they will take action or not.

Silence is golden for me. I live in the country and hear only my pets, birds, crickets, and the wind in the trees.

After I published my first book, my sister, known as Kali Willows, began writing. She fell as in love with it as I did. She has a number of short stories.

I always carry a notepad with me, even on vacation. If I'm on the computer when the story 'hits', I open a Word document and start typing until I get it all out. I've got tons of notes that I never throw out. You never know when a story will strike!
