The life of an actor is very random. It can be exhilarating but terrifying - you do wonder day to day where the next job will come from. Some of my friends are very talented people, but you see them out of work - which can be tough. If you wanted that kind of security, though, I guess you wouldn't be an actor in the first place.

I suppose it's whether you want to be a famous person, or whether you want to be an actor. You have to decide what your priorities are. Great actor, huge star. Sometimes, the two walk hand in hand. Most of the time, they don't.

I only went along to youth theatre with a friend when I was young to try to make myself a bit more sociable. But the whole thing was quite sore; it really hurt me trying to get into drama school. It was a world I knew nothing about - it was very middle class; all that usual stuff. But I was young, determined, and I just went for it.

I admire people who overcome obstacles or who have to commit - I've always really admired commitment, whether it be a commitment to living or a commitment to love. People who commit to a moment. People who are not somewhere else, but in the room with you.

I think age is sometimes just a number. But it's a real joy. Young actors don't come with any of the baggage that we load ourselves up with. They're not worried about their profile, they're not worried about how good they look, or all the nonsense. They just tell the story and ask: "What happens in this scene?" Well, I'll do that then. And professionally it's good for you because it means that you're forced to do the same thing, and that's always a good thing.

As I get older, I want to draw on my experience to make roles better. I see that in the older women who inspire me - their experience makes them better.

The experience of having a child does crack you wide open. I felt like I suddenly had to rebuild the skin that I'd grown over the years before having a child. Perhaps that might be quite interesting in terms of acting.
