"American Horror Story" season 4 spoilers revealed that the series will face a major overhaul as fans would be treated to a very different series unlike the previous three seasons. Meanwhile, cast Kathy Bates confessed that she couldn't sleep after shooting her first scenes.

Showrunner Tim Minear revealed "American Horror Story" season 4 spoilers to The Hollywood Reporter whe he promised that "Freak Show" is "not like the first three seasons."

Sarah Paulson, who will play conjoined twins Bette and Dot, told THR that this early she's already playing favorites. "Bette is my favorite right now, and it's a week in and I don't know why that is," Paulson told the site. "It feels very organic to me and I love her."

She also promised that fans would be pleasantly surprised by how Bette and Dot will be presented in the "Freak Show" because "it's done in a way that's never been done before in a sense that no person has played a person with two heads."

FX head honcho John Landgraf dished out more "American Horror Story" season 4 spoilers to Entertainment Weekly when he talked about the tone of the show.

"Some years it's going to be big and bright and brash and campy the way 'Coven' is," he said. "Other years it's going to be dark and brooding-like 'Asylum' was," he said.

"I guess I would put Freak Show half-way in between the two. It's not quite as brooding and formal and Hitchockian as 'Asylum,' it's got a little bit more humor and a little bit more camp, but its got a brooding period feel to it also," the FX CEO said.

Meanwhile, Kathy Bates revealed to Den of Geek that shooting "Freak Show" unnerved her a bit.

"The man behind the curtain has come out in front of the curtain. It's so lame. I must be nervous. After my first scene one week, I got home and couldn't go to sleep, and then I slept for 30 hours - and that was without drugs. I swear to God, I think he scares the sh-t out of me," she said.
