During a panel for "Scream Queens" and "American Horror Story" on Sunday, Ryan Murphy revealed on E! News that not only will AHS be revisiting both "Murder House" and "Coven", but will be revisiting them together, with characters from both seasons appearing at the same time.

"We do know what we're going to do," Murphy said during Entertainment Weekly's PopFest. "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."

The crowd cheered at the news, including Emma Roberts, who portrayed Madison Montgomery on "Coven" and spoke her desire to return to the show earlier in the panel.

Murphy clarifies his vision, stating, "There will be characters from Murder House and characters from Coven together."

On October 2011, the first season of "Murder House" premiered and followed a family - Connie Britton, Dylan McDermott, and Taissa Farmiga - who moved from Boston to Los Angeles and accidentally bought a haunted house filled with ghosts and surrounded by some questionable neighbors.

On the other hand, the season three of AHS, "Coven", premiered in October 2013 and focused on a group of witches in New Orleans.

Murphy added that the crossover won't happen next season because of the issues regarding scheduling.

"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," he said. "So yeah, it's fun. It's weird."

The announcement opens an opportunity for various "AHS" actors to come back into the fold. Stars like Dylan McDermott, Kate Mara, Alexandra Breckenridge, Zachary Quinto, Gabourey Sidibe, and, of course, Jessica Lange, could all presumably return in a "Murder House"-"Coven" crossover.

Meanwhile, the current season of "AHS", "Roanoke", is nearing the end of its 10-episode run. It airs Wednesday nights on FX at 10 p.m.
