It might be quite boring if you did something and thought it was perfect.

I've never, ever done a piece of work - and can't imagine doing a piece of work - when I've thought, 'I was pretty perfect in that.'

My family weren't actors, and we didn't know any actors. It wasn't even something I was aware you could do as a job. I thought you had to be a Redgrave or a Barrymore before you were allowed to go to drama school.

I know it sounds ridiculous, but I haven't quite got over the miracle that you plant things, and they do sprout up.

I was told it might be quite difficult to conceive, so it really was a great blessing when my pregnancy suddenly happened. I had been diagnosed years ago with polycystic ovarian syndrome, which can affect your fertility - but luckily, in my case, it didn't.

You can finish the day's filming or the whole shoot or watch something months later and think you could have done it so much better. It's frustrating.
