You had me at wig.
I so enjoy that wig.
Ryan is good at a lot of things but his wig work is unparalleled.Oh, its extraordinary!

We could talk about the wig throughout the whole interview.
I was starting to piece together that he might not be considered to be the good guy.
I had no concept of who I was playing until two days before I started filming.

Your major relationship on the show is with Kathy Bates.
Working with both of them, they are such specific actresses and incredibly talented and furiously hard working.
I have loved it so much.

[We] have grown really close.
She was in the most iconic films ever.
Speaking of icons, you had to try and kill Jessica Lange in the pivotalMurder Housecrossover episode.
I felt like, What could I bring to this table that is going to add to this?
Not competing, but to just be able to stand in the scene with them.
Then because she is so good, she makes you so good.
She is so present that youre forced to be present with her.
You also had to be in the Rubber Man suit in that episode.
Dylan (McDermott) and Evan (Peters) have both told me its unpleasant.
It takes a lot of lube, you are extraordinarily hot or freezing cold there is no in-between.
and knowing that people are going to see the hood come off and its Michael Langdon.
I researched hand movements.
He always has his hands behind his back when hes illustrating something.
Be ready for some really significant surprises.
Once you are onAHS, you become part of the repertory company.
Would you do another season of this show?I would do anything for Ryan Murphy, absolutely anything.
Truly this experience has been the most extraordinary experience of my life working with these people.
We stop filming in a week and I dont know what Im going to do.
Its going to be a huge period of depression.
OnHouse of Cards, you have some intense scenes with Robin Wright.
It was one of my favorite shows.
And to be on it all of a sudden was just a mind-boggling experience.
because we met at the readings.
And I said, Claire!
Oh my God, I could have vomited.
Everyone felt a real sense of banding behind Claire Underwood and closing the story.
I had started filming in October and then came back in January so I experienced both moods on set.
So that felt very good.
It felt like we were honoring something that needed to be honored and deserved to be.
Whats next for you?
Do you know yet?I dont know whats next.
I am excited about the great unknown.
AfterVersaceandAmerican Horror Story, if that was the end of the line then I can go happy.
I feel like I really, really achieved something and have been a part of something special.
