American Horror Story: Coven star Jessica Lange revealed in a recent interview that she plans on leaving the show after Season 4.

"I'll do one more season. That'll be it."

While FX hasn't officially renewed the hit series for a fourth season, it seems inevitable after the record-breaking ratings from the Season 3 premiere. The actress also spoke about her character, Fiona Goode.

"The spine of the character is that thing of a wasted life," Lange says. "The idea that this woman has gone through life basically like a bulldozer, in the most selfish, self-centric fashion. Things just falling by the wayside. Now, she's at a moment in her life where she's confronted by all these things - her mortality; the fact that maybe she's alone and what did she discard on the way, like her daughter, that could bring something meaningful, but it's too late. That Portrait of Dorian Gray element fascinates me: What do you trade off for this idea of eternal youth and beauty and how much are you willing to sell for that? How much of your soul are you willing to give up?"

She also spoke about how this season is starting off with a lighter tone before delving into darker material.

""I think Ryan was maybe even surprised by how fast and how dark it got last year. Of course, that's right up my alley. I like that a lot. But I think this season was a deliberate attempt to lighten it and add some humor. And I'm not against humor; my sensibilities just always tend toward the more tragic or the darker. Oh, it's going to change really fast. It's only going to get darker. We're going to move into territory that's much more interesting to play than these first few episodes."

She also spoke about Fiona's romance with Danny Huston's The Axeman, a character based on a New Orleans serial killer from the early 1900s who was never found.

"I wanted a romance. Especially for a woman that's at the end of the line and for the first time in her life finds love."

When asked about working in New Orleans, she had this to say about that community.

"There's Madame LaLaurie, there's Fiona Goode, there's Marie Laveau, there's New Orleans. It's unique in this country I think, that city. It has this extraordinary ability to live in the past and the present. Time kind of melds. I don't know any other place like that. And so authentic still, to its culture and to the people. You feel on the street what these people feel about this place. I mean, you walk down the streets of New York and everybody just looks so unhappy. They're not all that happy to be here. But in New Orleans, you get this sense that this is home and we're connected. We're connected through generations and we're connected through the arts and the music and the food and the culture. I mean, it permeates the air ... not to paint too rosy a picture because there's a lot of darkness there, but what I find fascinating is how you can be in a place where you sense the decay and the decadence and the elegance and the spirit and everything is just moving together."
