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

For example, the character of Claire in In Dreams wasn't imagined enough by me. Annette Bening is a great actress, and she gave a great performance, but because I hadn't fully written it essentially the character wasn't finished.

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.

For me, the filmmaking has to be about the dramaturgy.

You've got to play what people think you are, rather than what you are. You have to have a sense of what you are as you're playing what people think you are.

The Company of Wolves doesn't belong in any category, so it's difficult to prepare an audience for it. It's not a horror film, it's not a fantasy film, it's not a children's film - so what is it?

Ireland is becoming like everywhere else, but that's the one I grew up in: the one that's hugely illogical. Rather wonderful, in a way. I never found this oppression of religion and that, but I did enjoy growing up in a culture that didn't need to be rational all of the time.
