Ryan Murphy, the co-creator of Glee, has a cast that just keeps growing for his latest project, American Horror Story. Now what’s weird about this latest cast addition is the two actresses are playing the same person. The Hollywood Reporter says Frances Conroy and Alexandra Breckenridge will both be playing Moira O’Hara, the housekeeper of a haunted house where husband and wife Ben (Dylan McDermott) and Vivian (Connie Britton) come to save their marriage.

The housekeeper will appear as a woman in her 60s (Conroy) to Vivien, while a younger version (Breckenridge) will appear to Ben.

Ryan Murphy has a good track record in a variety of different genres of programming, from Nip/Tuck to Glee and now this. He’s versatile and doesn’t stick to a formula when creating new shows, and that if anything has my interest in this show peeked. It’s a different idea for sure; a classic haunted house tale, but stretched into a TV show. And the cast is pretty impressive at this point, also featuring the talents of Jessica Lange, Dennis O’Hare, and Taissa Farmiga.

Still a lot can go wrong with a horror story. There’s a reason why most horror movies are terrible. They have to be scary and make sense, while still building believable characters. That’s hard to do in two hours, so perhaps American Horror Story has the upper hand with being a series; more time to build its characters and mythology. It’s a risky show, and sometimes risky can be a very good thing.
