Acclaimed filmmaker Mike Flanagan is tackling Stephen King’s epic fantasy horror series The Dark Tower, and there are already a ton of exciting updates about the new TV show. Starting with the publication of 1982’s The Gunslinger, the Dark Tower series is set in a bizarre parallel world in which a mysterious Western-style gunslinger named Roland traverses the land in search of The Man in Black and the eponymous monolithic tower. A stark departure from many of King’s other works, the deft blending of genres makes The Dark Tower one of the most unique book series of the 20th century.
