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.

Everything, every part that you approach has to be somehow rooted in yourself. You have to somehow root everything so that it's not just words coming out of you.

Some things you know about, you know what the ingredients are - maybe not all of them. But it's up to you to put in the amount. It's up to the director to nag you until you get it right.

I need to learn every day.

I was in Yorkshire. We were a family of five and I used to be sent sometimes to get the rations for the week and was easily able to carry them back. It was like one egg and a tiny bit of tea.

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've figured out what to do so far, but it's always the next thing you come to where the man with the bucket of ice cold water is waiting - whoosh! in your face. That's why you work with directors who know what to tell you to do.
