I don't think we have enough imaginary creatures in cinema. It seems like we're stuck with zombies, vampires, and werewolves. We should have everything. We should have minotaurs. We should have elves. We should have mermen in popular culture. But instead we've stuck with vampires.

Never make a promise - you may have to keep it.

The whole Ireland was taken over by greed and materialism. It was extraordinary. The price of every house had skyrocketed. If you were a small farmer and you had two fields outside, if you built 17 bungalows on them all, you become a millionaire, that kind of thing. It was extraordinary to see how rapidly that kind of ethic takes over a whole culture, but that's what's happened to us since the year 1998, about. It's completely extraordinary how little regard the culture had for the landscape. The country is now full of these half-built industrial parks and hotels.

The Company of Wolves is about how society teaches young women to look at themselves, and what to be afraid of. It's about a girl learning that the world of sensuality and the unknown is not to be feared, that it's worth getting your teeth into.

It's the opposite journey from what I've usually done with films. I find it very easy to go from, say, a lit, pleasurable environment, like what you see outside there, to a very dark place. But the opposite journey, which is what this movie takes, is much more complicated.

The most difficult thing is the organization of people and the expression of your intentions. It's very easy to have a picture in your head and to imagine that you've told everybody about what you need.

I've also worked hard portraying an Ireland which is fast disappearing. Ireland was a very depressed and difficult place in the 1980s, and I've tried to include that in the script. I worked really hard to find the heart of the book.
