Make yourself smell nice. I even wear perfume sometimes when I'm alone.

I think that it's important for every single person, no matter what they do in life, to participate in the well-being of humanity and the planet. Don't let a year go by knowing you didn't make an effort to do something - no matter how small - outside your own problems and drama.

There has never been a female director who has won an Oscar. There has only been one woman who won at the Cannes Film Festival.

I love family films. Of course, as a mother who has to watch so many movies, you really appreciate it when somebody makes a film that is for everybody - family entertainment that's really for the family, where everyone has a good time.

I believe that change keeps you young.

I received so many hate letters when I breast-fed a starving baby in Africa. I was in Sierra Leone in 2009 and I was weaning my child at that time - she was not there with me. There was a hungry baby who was crying because his mother had no milk, and I thought, 'Why throw away my milk if I can give it to a baby who needs it?'

I am so, so lucky. I am the luckiest girl in the world, really. And still with access to everything I could possibly want I still say 'Oh dear, what am I going to wear today?' There's no ending to that question!
