My conception of it was that in a normal film you have a story with different movements that program, develop, go a little bit off the trunk, come back, and end.

If movies have to satisfy every possible quadrant before they're even made, they're dull. You only get great things when people overreach themselves.

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.

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 truth is that seals look more like dogs. And I'm surrounded by seals because I live by the sea. They're odd bloody creatures. Not fish, they don't have gills, they should have legs, but they don't. They're the weirdest things, you know?

I mean I grew up in Ireland, so one would have to be consciously blinkered not to have reflected on the issue of political violence because that was the story since I was 19 years old or 20.

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.
