I've done my share of period stuff. I'm not sure why, but people say I have a period face. The bread and butter of British TV is Jane Austen adaptations and bridges and bonnets and boats and horses.

I always found the extraordinary loss of life in the First World War very moving. I remember learning about it as a very young child, as an eight- or nine-year-old, asking my teachers what poppies were for. Every year the teachers would suddenly wear these red paper flowers in their lapels, and I would say 'What does that mean?'

I don't think anyone, until their soul leaves their body, is past the point of no return.

It’s always about, somehow, finding a part of myself that is relevant, and then turning the volume up on that particular part. So, I am all of the characters I've ever played, and I am none of them at the same time.

I try not to make plans. God always laughs at your plans.

I did a production of 'Journey's End,' an RC Sherriff play about World War I, at the Edinburgh Festival. I was 18 and it was the first time that people I knew and loved and respected came up to me after the show and said, 'You know, you could really do this if you wanted to.'

You've got to do something, even if it's just to kick-start the day. I use music. And running.
