I quite enjoy the lines on my forehead because they show my life. That’s my history and I like to see that in other people. Like this wrinkle is due to some girl who broke my heart. I don’t want to escape it in any way.

Sometimes if I stick in a character too much I feel like I might start to get blinkered, because I'm making my decisions too definite.

I don't think peroxide-blond hair is a beneficial look for me.

As an audience member and as an actor I much prefer to find ambiguity.

We moved to Ireland when I was two and we settled in Killarney, Co Kerry. Where we were living in Germany is very industrial and very grey and my parents wanted to have countryside around for my sister and I to grow up in.

For me, addiction comes down to basically where a pattern of behaviour has developed and that pattern of behaviour is becoming a very damaging cycle. It's sort of damaging your relationships, friends or lovers, it's damaging your own personal health and it's damaging for you and your workplace.

I take my work seriously but I can't take myself too seriously. I'm in such a crazy privileged position.
