When I was younger and in primary school, I'd do maybe a film a year, and I had to adapt to being away from everyone for a couple of months.

For me, clothes are about individuality. When I wear things that are different and it works, it makes me feel good.

I try as best as I can to have a normal life. People recognise you, of course, and that's very strange. But I sort of leave my working life behind when I go home. That's my other world.

My name means freedom in Irish.

I remember being on Atonement and it felt very right to be there. There was so much excitement every day. I remember very vividly how it felt to be a child on a film set, and that is actually really important to hold on to for as long as you continue to make films.

Once you move away from home, it's never quite the same again. You expect everything to be just as you left it, and it never is. It's almost the first step into adulthood, realising you've got to make your own way.

If you don't have eyebrows, you don't really have a face.
