I don't know that any woman could ever not think about that at some point - even making the choice not to do it and getting to the place of peace of choosing not to be a parent, there would have still been some struggle in between. I'm not a man but I don't think it would occupy their minds as much.

It seems like a lot when you have three movies back to back but that's not really how it is.

I go to a dance class myself called BBS - Body By Simone - its little mini dance routines and I am often the oldest person in the room although I forget that. I'm fairly fit.

My mum put me in drama classes when I was about 14. I'd been going on about it for some time, so maybe it was a way to shut me up.

Since I had children I have taken huge amounts of time off. In a way it's a really good thing, in this show business especially, to have lots of private time, having lots of time to be in the world to observe people and read and take care of my kids helps me to come back into work with a thrill.

In your 20s - and these are generalizations of course - I feel like I didn't care about as many things or as many people, or even myself, as much. There's more recklessness and more ruthlessness; you're not as considerate of how things land with other people I think.

I love being outside with trees and water, lying down somewhere or walking. I do transcendental meditation, which keeps me calm and steady.
