It was revealed on Monday that Kathy Bates had joined the cast of the third season of FX's "American Horror Story" and would be starring alongside Frances Conroy, Taissa Farmiga, Jessica Lange, Lily Rabe, Sarah Paulson and Evan Peters (all of whom will be playing new roles).

Bates will reportedly play an old friend to Lange's character who is soon revealed to actually be a nemesis. Talking to TVLine, producer Ryan Murphy talked more about the character.

“Oh, Kathy’s never [played] someone this bad,” Murphy said. Her [character] is a bad, bad woman!” he said, adding that she'll be “five times worse than [her] Misery character — which is why she liked it."

"When I pitched this to Kathy, her mouth was drop-jawed because what I was pitching actually happened," Murphy continued. “It’s a true event… You’ll see. It’s some good stuff.”

Season three is again planned to run for 13 episodes with production slated to begin this summer and the season premiering this fall.
