Filming is underway on a feature adaptation of Stephen King's Gramma. Titled Mercy, we now have the official plot synopsis released by Universal:
"Based on a short story by Stephen King, Mercy tells the tale of two young boys (The Walking Dead’s Chandler Riggs and Super 8’s Joel Courtney) who move with their mother to take care of their dying grandmother at her decrepit farmhouse. When they suspect that the elderly woman they love has encountered a dark spirit, they fear she might not be the only one who won’t make it through the summer alive. Once George (Riggs) and Buddy McCoy (Courtney) arrive at their Gramma Mercy’s (Shirley Knight), what they find inside her 150-year-old home is nothing short of terrifying. As the brothers experience deeply disturbing phenomena they believe to be the work of an ancient witch, they must fight for their lives and overcome the evil forces threatening their family.
Directed by Peter Cornwell (The Haunting in Connecticut), Mercy is produced by Jason Blum of Blumhouse (Paranormal Activity, Insidious, Sinister), McG (Terminator Salvation, Charlie’s Angels) and Mary Viola (Brooklyn’s Finest, We Are Marshall) of Wonderland Sound and Vision."
As previously reported, Dylan McDermott, Frances O’Connor, and Chris Browning are also starring in the movie. A release date has not been announced, but we'll let readers know as soon as it's set. Stephen King's Gramma was first published in Weirdbook magazine and was part of 1985′s Skeleton Crew.
