Series creator Ryan Murphy was recently on the red carpet of The 64th Primetime Emmy Awards and whispered that he had a new casting scoop. When he was asked what the spoiler was about, this was his response.
"It's about Eric Stonestreet coming back to Horror Story. He's coming as a killer. [He has] a really good scene with him and Sarah Paulson."
It isn't known which episode recent Emmy-winner Eric Stonestreet will appear in this season. He previously portrayed Derek, a patient of Dylan McDermott's Ben Harmon in the Season 1 episode "Piggy, Piggy".
