Deep down am I superstitious? No. Do I believe in trying to be as kind as possible and as compassionate as possible because ultimately you're alone with yourself and your own conscience, and you want that to be as clear as possible? That's not superstition. You have to just try and stay pure and know what you value.

I dig my heels in every now and then, and think 'I'm not going to do what's expected or what people think is the right thing.' So I have a little bit of that in my personality.

I want to go home at night and feel discomfort.

I never like to tell people what they should take.

In particular, for my character, Celeste [in Big Little Lies], there was a way in which we wanted to present her, because she has sort of barriers that she has to put up for protection because of things that are going on in her life. Yet she wants to be, I suppose, very presentable but neutral.

I auditioned for the role of an angel in the Nativity play at school. I didn't get it. I auditioned for Mary; didn't get it. So I made up the character of the sheep who sat next to Baby Jesus.

I think if you have someone to love and someone who loves you, that's the greatest beauty secret.
