Dylan McDermott Cast in Stephen King's Adaptation of GRAMMA

Dylan McDermott has been cast in the lead role of the big screen adaptation of Stephen King's short story Gramma, which had been re-titled... Mercy.

The story is part of King's 1985 short story collection Skeleton Crew. It follows two young boys who go with their single mother (O'Connor) to take care of their elderly, senile grandmother named Mercy, only to discover that she's a witch who made a pact with a dark force many years before.

The coolest part about this story is that its set in set in H.P. Lovecraft's the Cthulhu Mythos. It includes characters, creatures, and unearthly powers that are featured in Lovecraft's work.

McDermott joins the previously cast Frances O'Connor. Peter Cornwell (The Haunting in Connecticut) is set to direct it from a script written by Matt Greenberg (1408, Halloween H20). Jason Blum, best known for the Paranormal Activity franchise, will produce alongside McG.
