I'm a bit of a Doubting Thomas - always worrying about things.

Having a career is a bit like navigating an Atlantic crossing - you have to make sure everything is keeping and is balanced.

I think I'm inspired mostly by other artists that aren't actors, like writers or singers or artists, for being so brave.

I know I can be bolshy and really unpleasant, and it always happens if I lose confidence in the people I'm working with. If I've got no confidence in what I'm doing and they don't provide me with some assurance that we're doing the right thing then I bully people. I'm a horrible bully.

I mean my father was killed when I was six. And I only have tiny, tiny flashes of memory.

I was terrible at school.

If you make a film about a pig farmer in Wales and you are a huge hit as the pig farmer's wife, the next thing is you'll be asked to do a film about a sheep farmer in Scotland.
