15 Best American Horror Story Cast Members
5. Frances Conroy
Appearing in seven seasons, the phenomenal Frances Conroy is one of the show's most prolific mainstays, and also one of its most noticeably talented.
She first appeared in Murder House as housekeeper Moira O'Hara (a role she shared with the also-brilliant Alexandra Breckenridge), who had a dark past with Constance Langdon (Jessica Lange) and two distinct looks depending on who was looking at her.
She had a brief role as the Angel of Death in Asylum, and played the powerful Witches Councilmember Myrtle Snow in Coven. With key roles in Freak Show, Roanoke, Cult and Apocalypse, Conroy proved time and time again to be one of the most gifted actors on the show.
Even if she was occasionally underused, she made it a joy to spend time with her characters, most of whom are innocent women pushed into morally ambiguity because of their tragic lives.
Conroy is set to return in season ten, promising some more striking characters in her future.
