I think you know what you're up against when you take on a piece that you know is going to involve dragging up a lot emotions - you can end up being deeply immersed in gloom.

If I want to run around a field when I'm 70, I would like to have that option.

Running gave me a focus to start looking after myself, to eat properly, and focus on building up my strength.

I always start from scratch with a character - they're never based on anyone else. You get ideas of what people look like, and I'm a great people watcher. You can draw inspiration from people.

I think some people think that being on television makes you a sitting duck, but you have the right to remain private.

I could suddenly see the pressures all around; these endless magazines and cheap reality TV programmes poking at women, humiliating us for every flaw. It makes me so angry. I really wonder what it is we are doing to ourselves, because I do think women can be the worst ones for picking each other apart.

I still love coming into work everyday after so many years working as an actress. I've been working more or less continuously and I find I have to really want to do the project to make it work because you have to put such an enormous amount of effort into it.
