Half of my mum's family is Welsh. I remember when I was a kid she used to read to me, and witches and wizards in books always had a Welsh accent, so I guess I took it from that really.
I love costume dramas, I love performing in them, because in a funny kind of way, you feel more free. You know about the period, you can read the books, you can see the paintings, but you've never actually going to know what it was like. You can kind of stretch those boundaries a bit.
It's a difficult thing when you try and make a film of a book that you really love. You have about two hours to tell the story, and it's never going to be enough.
