“1984” is the ninth installment of Ryan Murphy’s horror drama. The uber-producer previously unveiled a teaser for the season, stylized in the vein of 1980s slashed movies. While the teaser did not reveal returning cast members, Murphy also previously announced that Emma Roberts would be part of the cast.
