Earlier this year American Horror Story creator Ryan Murphy promised he wouldn’t repeat the mysterious Season 6 approach to themes. Going forward, fans will always know what they’re getting into in advance. Murphy is already making good on his promise. At Entertainment Weekly’s PopFest on Sunday, he revealed that an upcoming season of American Horror Story will re-visit two popular themes: Murder House (Season 1) and Coven (Season 3) for a jam-packed cross-over event.

Murphy cautioned that the New Orleans/Los Angeles mash-up season won’t be up next on the docket for American Horror Story. “It’s not going to be next season,” he said. “But we are going to do a season that’s a crossover between Murder House and Coven together, which is very bizarre.”

The hold up, it seems, might be scheduling which could indicate that Murphy is pursuing some early American Horror Story favorites who aren’t in the regular rotation anymore. What are Connie Britton, Dylan McDermott, Alexandra Breckenridge, Kate Mara, Gabourey Sidibe, and Zachary Quinto up to these days? (Okay, we know the answer to a few of those.)

But, tantalizingly, Murphy mentioned that he’s already rounding up the troops: “There will be characters from Murder House and characters from Coven together. I’ve [already] started going to actors from both of the seasons, quietly, saying, ‘I think in this window, if you could fit us in. So yeah, it’s fun. It’s weird.”

And since Murphy has proven he’s not shy about one actor playing multiple characters in any given season (think Sarah Paulson as both Hypodermic Sally and Billie Dean Howard in Season 5), the cast combination possibilities here are endless. Murphy did not guarantee anything, but I think we all have our fingers crossed for Evan Peters to reprise his role as Tate Langdon. And what, really, would be the point of doing Murder House and Coven without at least one Jessica Lange character?

The biggest sticking point, of course, will be the rule of Season 1 which is that all the ghosts in the Murder House are physically stuck to the confines of the property with the exception of Halloween night when they get to roam free. Then again, if anyone can free some ghosts from their earthly Angeleno prison, it’s a coven of witches.
