OK, so, strap in for this one, it's time to do some reaching. The Entertainment Tonight interview, mentioned earlier, took place at Ryan Murphy's Hollywood Walk of Fame star ceremony. Murphy wouldn't give away the theme for season nine: "I can't say what it is! I'm going to this luncheon, and many of the Horror Story actors are there, and I'm gonna tell them for the first time. So I have to tell them first." If you'll permit, I'd like to jump to some conclusions: at least some of the Horror Story stars at this luncheon will be in season nine.
Based on Instagram posts, here are the AHS alums who were in attendance: Emma Roberts, Cody Fern, Billie Lourd, Finn Wittrock, Leslie Grossman, and of course, Jessica Lange and Sarah Paulson.
Again, it's not a guarantee that all of these stars will appear, but I'm willing to bet some of them are on the roster. (We're looking at you, Sarah Paulson.)
