Savor these Horror-less months while you can, TV fans. FX's anthology screamfest will be back before you know it for a fourth round of thrills and chills — entitled American Horror Story: Freak Show. But who will be back for the horror?

We do know that Jessica Lange (Fiona Goode) will play a role. The 64-year-old actress — who has earned an Emmy Award for her work on AHS — announced that she will return for a fourth and final season on the show. She'll play a German ex-patriot who has rescued "unusuals" as performers in her sideshow. The story will take place in Jupiter, Florida, around 1950.

Those "freaks" will be played by Kathy Bates and Angela Bassett — who joined the series for Coven — and Sarah Paulson, Evan Peters, and Frances Conroy — who have been around since Season 1, Murder House.

And, at PaleyFest, Ryan Murphy revealed that Gabourey Sidibe, Emma Roberts, Denis O'Hare, and Jamie Brewer would be returning in some capacity — and that The Shield star Michael Chiklis is joining the cast.

Unfortunately, Lily Rabe will likely not be available — she's taking a lead role in the ABC alien drama The Visitors. The show still in the pilot stage, so there's a chance ABC won't order it to air, but don't hold your breath.

We might also see cast members returning to the show after skipping Coven. If CBS cancels Hostages, Dylan McDermott (Murder House's Ben Harmon) might be available, unless his Kevin Williamson pilot is picked up. Zachary Quinto (Asylum's Oliver Thredson) could potentially film a part before returning to the Star Trek franchise. Chloë Sevigny (Asylum's Shelley) has expressed interest in coming back. As for Connie Britton (Murder House's Vivien Harmon), well, we might prefer to see Nashville renewed than to have her return to the show — but here's hoping she can pull double-duty!
