I found out a few months after we started [True Detective] that I was pregnant.

"OK, well everyone makes a mistake, right?" But then when you think it probably happened again that's when you think: "Shame on you once and shame on me twice, or however that saying goes." But everyone's been down that road. It's not about the little things anymore, but the major things that tell you if you don't move on at that point then I'm a fool.

I think the first thing is to recognize that there is an ebb and flow to your career. There are going to be moments that are really high, and then you're going to have moments where you step away for a little bit, and maybe that's just by choice or maybe you have a family.

I've never felt limited by my circumstances, no matter what they were. Even when I was living in Iowa, it wasn't like I had big dreams, but it wasn't that I felt I couldn't have any. I always felt very capable.

Woody [Harrelson] and I actually worked together years ago on North Country. So I felt completely at ease.

Everything looks more beautiful in retrospect.

So, it was really important that I go do the necessary research. In doing the research, I spent time with a lot of medics and women down at Fort Bliss. I went through an intensive medical course there, with other medics. And then, I really sat down with all of the women that had been deployed, or were getting ready to deploy again. The common thread for them was family, and what a struggle it was for them to come home and face their children and flip a switch.
