I can sleep anywhere! I can come off stage during the interval of a play, lie down for four minutes then wake up feeling better.

So often when you meet child actors, they're weird - they're freaks. No, I mean it, they're really odd people.

To be honest, my husband and my children are my best friends.

I listen to Radio 4 all the time. I didn't go to university, so that's my further education.

If you're constantly frightened of being unhappy, how bloody exhausting must that be?

Theatre is liberating because it only works if it's truthful, That's what it requires. That's not true of film: the camera does lie.

I used to say that theatre was my favourite thing. But the more I do film, the more I appreciate it.
