When I was growing up, I wanted to be my half-sister Lucy. She was 14 years older than me and was impossibly glamorous. I grew up in awe of her.

Older men are wiser and that is much cooler to me. I've never been one for going out clubbing or getting off my head, so I always gravitated to men who were similar. They just tended to be older. I think you have more of an adventure with an older man. And a happier journey.

I've always believed in trying to be as open as possible. I think it almost comes with the job - if you can bare your emotions, it makes for better acting.

My mother was very ill when I was 18. She had a brain operation and then a nervous breakdown. It's very strange when you see your parents, who have always been your pillars of strength, suddenly become vulnerable. You don't know whether to be angry that they are not strong or devastated.
