I think you can teach people a technique - you can teach them how to use their voices, how to breathe properly, how to move their limbs a certain way. But to actually explain how one performs comedy or drama or tragedy isn't the same as the movements one makes.

This is just the loveliest news. I'm so happy for everybody involved, and so proud to have been part of the wonderful experience that Philomena has been.

The secret of my success is my mother, who was from Dublin. All my relations are in Dublin or in the west, or as I found out, we went to Rostrevor in Northern Ireland to film and I got out, while they changed cars around, and this man said to me: "You know you have cousins in this town? And they're coming down to see you..." And so they did. I'm sorry we didn't go to a lot more places, so that I could find a lot more cousins. So, that was good. It's entirely because my father was also brought up in Dublin. So, that's my link.

I like to push myself beyond the limit every now and again.

The more I do, the more frightened I get. But that is essential. Otherwise why would I go on doing it?

I once said to someone when I was playing Lady Macbeth and they said: "That's tricky, emotionally, what do you do about murdering your husband's cousin?" And there are, of course, things that aren't in your personal repertoire that you have to somehow understand by reading or watching other things and listening to other people talk about them.

Every experience that you experience yourself you use, because that's our craft.
