I find that I'm just drawn to anything that's going to challenge me as an actress. So any time I get a chance to do a little comedy, that's also a nice change for me. Most of the time people think of me as a dramatic actress and singer. And there's a challenge there because comedy is hard. What do they say? "Dying is easy; comedy is hard."

It's easy to spend - especially in this day and age - to spend your time not being in the present. It's very easy to be way ahead. What's tomorrow and the day after that?

I think in the end there is one ultimate goal with all my careers, and that is, as a performing artist, you want to explore the deepest, most truthful way to express a point of view, or whatever the character is thinking, or whatever emotion you're trying to convey. I think with the different media it's just about what muscles you use to express that.

I'm still an artist who's searching, trying to evolve, an artist who - nine times out of ten - is dissatisfied with her work, and beats herself, and goes out there and tries again and again, and falls on her face and looks for new challenges.

A doctor can be a doctor today and they will be a doctor tomorrow. But an actor, well you're not working at anything right now, whereas the doctor is going to have their job tomorrow, for the most part. So there's the insecurity of that, and you have to go where the work is.

I think it's absolutely essential to encourage creativity. I think we come in as these wide-eyed sponges, ready to create and absorb and evolve, and I think more often than not we are squashed, the older we get.

Pedigree matters: if you break your shoulder trying to open a door, it's much harder to play the game once you get in the room.
