During Entertainment Weekly's PopFest event, "American Horror Story" creator Ryan Murphy announced that one of the future seasons would finally be a crossover event, intersecting the tales and characters of season 1, the "Murder House" season, as well as season 3, the "Coven" season.
As per EW's official report, Murphy explained this crossover would not be season 7, but it is in development, and it may happen very soon. This would mean it could be season 8 or season 9, depending on when the script is completed and when casting schedules are finalized.
"We do know what we're going to do," Murphy explained to the crowd attending the Los Angeles event. "It's not going to be next season, but we are going to do a season that's a crossover between 'Murder House' and 'Coven' together, which is very bizarre."
He then confirmed that some characters from both seasons would be coming back for the crossover event, but he did not state who he had in mind. He did point out he has begun approaching some of the actors, some of which had not returned to the series since seasons 1 and 2, hoping to get them back for the crossover.
Screen Rant also points out that the details regarding the crossover's timeline are yet to be revealed. "Murder House" and "Coven" take place across multiple eras and involve several different characters. It is widely speculated that the new season will take place after the most recent events from "Murder House" and "Coven."
It is possible that the new crossover will be a sequel to either or both series. It is also unknown if other stars from the previous seasons will be coming back for the crossover event. Given how "American Horror Story" is an anthology, with each season separate from the others except for a few cameos, it is likely that some mainstays will return either as new characters or to reprise previous roles they have played.
