Ryan Murphy sat in on his very own mega-panel Sunday at Comic-Con with the casts of both “American Horror Story: Hotel” and “Scream Queens.”

Murphy, famously known to stay mum on spoilers, offered up a few details on the upcoming season of “AHS,” much to the delight of Con attendees in Hall H.

“Everybody on this side of the table are bad boys and girls this time,” Murphy said looking at cast members Angela Bassett, Matt Bomer, Evan Peters, Sarah Paulson and Kathy Bates.

The actors, for the first time, also revealed their character names. Bomer will play Donovan, Peters is Mr. March, Paulson revealed she is Hypodermic Sally and Bates is Iris.

As for the most anticipated star on the new season, Lady Gaga, Murphy says she’ll also play bad — which is something the star requested. “She said, ‘I want to be evil,'” the show creator recalled of his first meeting with Gaga, who approached him for the show, as she’s a big fan herself. “I said, ‘You came to the right place.'”

“It was one of the weirdest things of my career ever,” Murphy continued, recalling Gaga approaching him for her part. “‘Horror Story’ has a lot of fans obviously and I get calls from some people…how it happened with Gaga is she wrote and said, ‘I love the show, would you consider putting me on it?’ And I wrote back, ‘Yes. CAPS CAPS…’ The best call ever is ‘Please wait for Gaga’…and she got on the phone and could not have been lovelier.”

Murphy said that the superstar will shoot all of her episodes during one window to accommodate her busy schedule. “She likes to do one thing at one time,” he explained, confirming that she will only be acting — no singing for Gaga in “AHS.”

The creator also teased Gaga’s style on the series. “When you work with someone like her, you sign up for something that is larger than life and I think that’s what you want,” he said on the panel. “Part of her role involves fashion. You want Lady Gaga to look a certain way. The designers have been coming out of the wood works with looks for her.”

The fifth round will also bring back even more familiar characters, Murphy confirmed, bringing truth to longstanding theories that all “AHS” seasons are connected. “Things are connected,” he said. “This season, you’ll see more and more and more of that. Characters from previous seasons will come check into the hotel.”

As for “Scream Queens,” Murphy also remained tight-lipped, but did promise that the killer is in the premiere episode. “If you go back and watch that episode at the end, I think it’s very clear,” he said, shocking the cast who does not know the killer’s identity. Lea Michele offered up her own theory, if her character Hester happens to be the murdered. “Maybe her neck brace is her motive — she’s like, get this thing off me!”

Jamie Lee Curtis, however, did reveal a detail that sent Hall H into an uproar: there will be a moment in “Scream Queens,” which is an homage to “Halloween.”

Curtis also applauded Murphy and the writers’ team on Fox’s horror-anthology, explaining that she was attracted to the project because of the quality of writing. “For somebody who spent her life in horror films that honestly weren’t written well it’s an honor.”

Though both “AHS” and “Scream Queens” are anthology series, Murphy says they’re very different shows with different formats. “The thing with ‘Horror Story’ is every year, there’s a new story, there’s a new theme and the actors play different characters.”

And for “Queens,” he says, “there are survivors that go on to a different location and the characters that you have grown to love, many of them will go on to the next season — and many will not.”
