When he isn't being mixed up with Dermot Mulroney on Saturday Night Live, Dylan McDermott has been appearing on American Horror Story, with his first on screen appearance in the FX drama series' second season taking place just last night. And it looks like he'll be sticking around the horror genre for one of his upcoming feature roles, as he's been cast in Universal's adaptation of Stephen King's short story Gramma, titled Mercy.
Stephen King’s short story Gramma was published in Weirdbook magazine back in 1984. And while countless King stories have made their way to the silver screen over the years (decades, really), Gramma has long been overlooked. Not any more. Peter Cornwell is stepping up to direct the horror thriller, using the title Mercy, and casting officially is underway.
