American Horror Story [SEP] Season 10
On August 3, 2018, the series was renewed for a tenth season. In November 2019, Murphy announced that some cast members from the first three seasons may return for the upcoming tenth season, saying, "[T]he people who helped build this show into what it is, who believed in it from the beginning, have been contacted and are interested. So, if you look at the iconography of the first three seasons, you can figure who I've gone to and who might be coming back." He also said that the tenth season would be "about reuniting fan-favorite actors to come back." Later that day, Sarah Paulson confirmed that she would be returning to the series for its tenth season in a lead role.
