‘AHS: APOCALYPSE’ ARRIVES AS ‘CASTLE ROCK’ CONCLUDES

It’s the end of the world as we’ve never seen it. Or something. “American Horror Story: Apocalypse” (10 p.m., FX, TV-MA) debuts. While many series arrive heavily promoted, “Apocalypse” remains a fairly guarded secret. As of press time, the FX site hadn’t even been updated to reflect its existence.

Suffice to say, it will feature many familiar faces from the anthology cast, including Sarah Paulson, Kathy Bates, Evan Peters, Adina Porter, Emma Roberts, Jessica Lange and Taissa Farmiga. Oh, and Joan Collins, too!

Hulu streams the final episode of “Castle Rock” (TV-MA), a series executive produced by Stephen King and set in a locale reverberating with references to his many works.
