Although Murphy and his stars were tight-lipped, they did reveal their character names: Bates is Iris, Bassett is Ramona, Peters is Mr. March, Bomer is Donovan and Paulson will play Hypodermic Sally.
"Actually everybody on this side of the table are bad boys and girls this year," he said pointing to the entire AHS team on the panel. "The fun thing about the show is I always want to write the opposite of the season before."
Murphy also revealed that Lady Gaga, who will star on the new season, will play an evil character as well. "She said, 'I want to be evil.' And I said, 'OK, you came to the right place,' " Murphy said.

Murphy praised his new leading lady, who he said asked him to appear on the show. "She's been very collaborative and incredibly fun. When you work with somebody like her, you sign up for something that I think is larger than life," said Murphy. "Part of her role involves fashion. You want Lady Gaga to look a certain way, so the designers have been coming out of the woodwork."
One thing Lady Gaga won't be doing is singing. Murphy ruled out musical numbers on Hotel after employing them heavily in past seasons, as well as on his other famed creation, Glee.
"Never say never," said Murphy. "I felt I got that out of my system. I loved doing it and I thought it was a weird thing that we did. But no, I feel like the fun of it is doing something different. So I feel like we did that."

Speaking to a fan theory that all the seasons of American Horror Story are connected, Murphy said that characters from previous seasons will check into Hotel. Said Murphy, "It's part of a very connected universe with a very cool thesis statement at the end of the run."
