While we don’t want to spoil the surprise for viewers who haven’t yet seen the “American Horror Story” finale by revealing which characters lived or died, Ryan Murphy, a creator of that FX series, had another surprise up his sleeve, announcing on Thursday that none of characters from its first season, living or otherwise, will return in Season 2, nor will the creepy Los Angeles mansion that was the setting for the show.

“The next year of the show – every season of the show – will be a different haunting,” Mr. Murphy said in a conference call with reporters. “So what you saw in the finale was the end of the Harmon house, and the second season of the show will be a brand new home or building to haunt.” He added: “Just like this year, every season of the show will have a beginning, a middle and an end.”

Created by Mr. Murphy and Brad Falchuk, who are also among the creators and producers of “Glee,” “American Horror Story” focused in its first season on a psychiatrist, Ben Harmon (played by Dylan McDermott), his wife, Vivien (Connie Britton), and their daughter, Violet (Taissa Farmiga) as they adjusted to life in a new home — one populated by vengeful and murderous ghosts, and located next door to the house of a faded movie actress (played by Jessica Lange).

“American Horror Story” has been a breakout hit for FX, drawing 3.2 million viewers for its Wednesday finale, the network said, and earning Golden Globe nominations for the series and for Ms Lange’s performance.

Mr. Murphy would not reveal which of his cast members would or would not be returning for Season 2, saying only that any actors who returned would be playing entirely new characters in a new story line and setting.

“The house is done,” he said. “It was a very sad day, in fact. It was like a week ago where we tore down all the sets. And usually when you wrap the first season of the show, you don’t do that. So it was kind of a weird but really satisfying moment. That was always the plan.”
