Murder House starred Connie Britton, Dylan McDermott, and Taissa Farmiga as the Harmon family, who encounter, battle, and befriend the paranormal inhabitants of a haunted mansion. Jessica Lange and Evan Peters costarred as Constance, a meddling neighbor, and Tate, a psychopathic teen ghost, respectively, and both jumped to Coven, Murphy's New Orleans-set exploration of witchcraft, voodoo, and Hellish ritual. Farmiga and Murder House alumni Sarah Paulson, Zachary Quinto, Lily Rabe, Frances Conroy, and Denis O'Hare also stuck around for the third season, which added Emma Roberts, Gabourey Sidibe, and Kathy Bates to the cast.
“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,'” said Murphy. “So yeah, it’s fun. It’s weird.”
Roanoke may wind up playing a role in connecting the two seasons. Murphy confirmed to EW hat Lady Gaga’s druid character, whose lifespan stretches from the first American colonies all the way to present day, is in fact the first "supreme," the top witch position established in Coven. Murphy also said that November's finale “is the wrap-up to Roanoke but the mythology and some of the characters will continue in subsequent seasons. So it’s the ending but not the ending." Can we expect The Avengers of the AHS universe?
