I'm a natural blonde, but I feel like a brunette.

Inspiration is the key to everything.

In Alien, Sigourney Weaver's role was written for a man. In Salt, Angelina Jolie's role was written for Tom Cruise. These things, when reversed, do prove to be just as exciting and entertaining with women in leading roles.

Early on, I knew I had ideas, but I wasn't sure when it was appropriate to bring them to the table and I was so intimidated by these titans that I was working for.

You're 30: You know stuff now. Your 20s were for 'ducking up,' as my auto-correct would say, and learning from those mistakes. (For instance, never again will I convince myself that sleep is for sissies and go straight from a party to the airport. You will not 'sleep on the plane'; you'll vomit in the security line. Go to bed.)

Do some yoga. I never feel more beautiful than after I've really spent some time breathing.

I feel like the luckiest person on the planet. 'Tron' was such a departure for me.
