Ryan Murphy is assembling quite a powerful group of women to round out the cast of American Horror Story: Coven, the third installment of his FX anthology series. The AHS co-creator took to Twitter yesterday to announce that Angela Bassett and Patti LuPone would both be joining the third season, set to debut in October and believed to center around witches.

The actresses join Jessica Lange, Kathy Bates, Gabourey Sidibe, Taissa Farmiga, Sarah Paulson, Lily Rabe, Frances Conroy and Evan Peters.
