I don't feel the need for religion. But I went on a yoga retreat last year and I do believe slightly in the karma thing and just being good and true unto yourself. And I slightly believe that you can attract good and bad to you.

If you're at an award ceremony, you're against your mates.

Having a child makes you strong and gives you chutzpah. It relaxed my attitude to the job; my center of focus shifted, which I think is very helpful, because even if you're not a very indulgent actor you spend a lot of time thinking about yourself. I don't think that is particularly healthy.

Her death has had a huge effect on me. It felt like a big hole appeared on my left side - apparently your left side is your mother - which I thought could never be filled.
