THE TOMMYKNOCKERS - TBA
Stephen King's stories are just as much rooted in horror as they are science fiction. And, in The Tommyknockers, the science fiction elements are front and center. This 1987 novel takes place in the fictional town of Haven, Maine, in which the locals become bewitched by a mysterious extraterrestrial artifact that's been unearthed in the woods. In 1993, The Tommyknockers was adapted as a TV miniseries, and now, a feature length adaptation is currently in the works, with James Wan (The Conjuring, Aquaman) attached to produce.
THE TALISMAN - TBA
In 1984, Stephen King teamed up with author Peter Straub to write The Talisman, a fantasy novel about a young boy who travels into a parallel world in order to find a magical talisman that might save his dying mother. There is currently an adaptation in the works, courtesy of Steven Spielberg (he's owned the rights to the book since its release, and though he may not direct the movie, he'll play some role as a producer), but it's been a slow journey getting it made to say the least. Josh Boone (writer/director of both New Mutants and The Fault in Our Stars) was announced to pen the screenplay in 2017, but few details have been released since concerning the movie's production schedule.
REVIVAL - TBA
Stephen King's stories often revolve around horror and religion, and his 2014 novel Revival is no exception. In fact, one of the two main characters is a priest who not only battles with his faith, but ends up opening a portal to another world. There are very few details surrounding production, aside from the fact that Josh Boone (who is also attached to direct not only The Talisman, but Kings Lisey's Story and a miniseries adaptation of King's The Stand) will direct, according to Deadline.
LISEY'S STORY
Speaking of Lisey's Story, this 2006 horror-romance novel from Stephen King centers around the titular Lisey who's dealing with the death of her husband. However, in dealing with her husband's death, she ends up entering a dark world in which her husband frequented when he was still alive. Just barely in the early stages of development, there are very little details regarding the adaptation, aside from the fact that Josh Boone is attached to direct.
SUFFER THE LITTLE CHILDREN - TBA
A short story in Stephen King's Nightmares & Dreamscapes, Suffer the Little Children revolves around an elementary school teacher who grows increasingly more suspicious of the children in her class. However, as she attempts to piece together the mystery, people in town begin suffering unexplainable deaths. According to Deadline, newcomer Sean Carter (Keep Watching) will pen the screenplay and direct, though very few other details have been released.
