American Horror Story - Interview with Connie Britton

So your new show is remarkably crazy.
Oh, you have no idea.

What did you think when you read the script?
I had this amazing conversation with Ryan about it, and then I read the script and I was like, “Wait, what?” There was so much going on, and it was obviously so different from what I had been working on. I was like, “Okay, I’m not sure that I quite get it,” but I loved the idea of playing this character that, while technically on paper I’m playing a wife and mother just like I had just been doing on Friday Night Lights, was so the polar opposite of what I’ve been doing for the last five years. It felt really intriguing.

How did Ryan pitch the show to you?
He said, “I’m making this show. This is gonna be like nothing you've ever done before in your life, and you will get to play something that you’ve never played, and this is about betrayal, it’s about infidelity.” And, of course, this is me coming off of quote-unquote “the best marriage on TV,” so I was like, “Interesting! I haven’t done that in a while.” He was so specific about it, and so specific about it for me. He kind of had me at hello. And then I read the script and I was like, “Okay, so, wait, how does this work?” And we had more conversations about it, and, even when we were shooting the pilot, I was like “I don’t understand how this is going to work, or go together, or whatever.” But he directed the pilot and I really just put my trust in him. Even though, again, a lot of the days I had the feeling like, “Wow, I don’t know what I’m doing!” And then I saw the pilot, and I was like, “That’s amazing.”
