I'm not an overnight success. I've been doing it for 12 years. It's been lovely and varied so far.

The number of people my age, younger now, a whole generation younger, who are fiercely bright, over-educated, under-employed and who are politicised and purposeless really upsets me. It's soul-destroying.

Even though my parents experiences were different from mine. I wasn't a child actor brat; I didn't travel with them in the circuit. But I got a look into their world, so I did know what I was getting into, to an extent. And they are a constant source of grounding.

It's the same thing, I think, whether it's breathing or meditation or yoga. And running is a great way of doing it.

Being on set is quite difficult, because it's so big and you've got to try and relax, which isn't easy when you know you're in a massive film. I was terrified for quite a long time.

I think what I loved in cinema - and what I mean by cinema is not just films, but proper, classical cinema - are the extraordinary moments that can occur on screen. At the same time, I do feel that cinema and theater feed each other. I feel like you can do close-up on stage and you can do something very bold and highly characterized - and, dare I say, theatrical - on camera. I think the cameras and the viewpoints shift depending on the intensity and integrity of your intention and focus on that.

If you can't fail, you can never get better.
