"Usually, you get a script and you have the whole story. All the acts are there, for a play. You know what happens in the first, second and third acts, and you know how it starts, where you go and where it finishes. [With American Horror Story: Asylum], it's a whole new experience. I don't know where it's going, and I don't know what's going to happen next. It's been an interesting way to work. It's made me work in a much more fluid, braver way, just taking every chance that comes along."
