Julianne Moore

I think to be courageous, you have to be afraid. For me, it feels very courageous when I go skiing because I'm very, very afraid to ski. It's dangerous! I feel very scared. But when I'm acting, I don't feel very scared.

I think people are always really surprised when they realise I'm not a very serious person and that I'm not tremendously serious about acting. I don't like to rehearse; I hate improv. Directors that don't like to talk, they're my favourite ones.

From 1961 to 1964, I was fortunate enough to work at a think tank in the Kenwood neighborhood of Chicago. As a writer and editor, I reported in a publication about the thinkers. Our offices were in a former mansion; I worked in what had been the ballroom. As I sat typing my copy, I imagined the dancers waltzing.

The importance of heart health became very real for me when my father died of heart disease seven years ago. Having experienced the loss first hand, I am inspired to do everything I can to break the cycle and prevent families from losing loved ones to this preventable disease.
