Children will be children, and they're inquisitive. If teenagers want to know what's out there, they'll look, but there are things that aren't for their eyes.

The funny thing about children is that, whichever room we're in, that's where they'll be. If I'm in the bath, they'll want to be in there too, playing with the toothbrush pot or brushing my hair.

There's nowhere to hide in the theatre. You can't be the one in rehearsal who doesn't know their lines.

'Upstairs Downstairs' and 'Downton Abbey' appeal to people because they're about our history, they look so beautiful, are written by amazing writers and have high production values.

Botox and other fillers make everybody look the same, with the big cheekbones where they fill you up. It's much cheaper to have a fringe - it takes years off everybody.

I don't like dirt. Cleanliness is high on my agenda, but I don't have a phobia of dirt. I'm just not keen on it. I don't really like dirty people or houses or smelly things.
