Eating at home is important for us, because we eat out so much when we're away. When I'm at home I cook a lot and we eat pretty healthily. I'm not a massive vegetable fan - I've got better since I discovered how to undercook them.

If oil exploration can threaten a place as beautiful and meaningful as Virunga, where next?

My whole family is quite petite, so I have good genes on my side. But I find it quite tiresome that we have to keep talking about sizes and how much weight we can lose.

I've never been onstage in my life.

The doctors say it dates back to a film where I had these huge prosthetic breasts because my character was breast-feeding. The weight of them, and of the baby, did my back in.

Onstage, there's no hiding; you either can or can't act. There's no second take.

People became more interested in my love life than in me, and that has a certain effect. You start to feel very empty and worth nothing, you start to become a piece in a board game you never wanted to play.
