Stephen King says fans should expect changes in Dark Tower movie

Stephen King says that despite the best efforts of director-writer Nicolaj Arcel, the upcoming adaptation of his novel The Dark Tower will have some changes that fans may not like.

Talking to Entertainment Weekly, King said that the chronological order the story follows will change to make sense for the adaptation. He said that while he knew fans of the book may be upset, once they see how the changes have been implemented, they'll understand why.

"It starts sort of in medias res, in the middle of the story instead of at the beginning, which may upset some of the fans a little bit," King said.

The author did assure people that the movie will start at the same place the book does, however, adding that he was very insistent that's how the movie should begin. King said that Arcel has been great about listening to his concerns and he believed everyone was on board with where the movie should start.

The Dark Tower follows Roland Deschain, a knight in the desolate land of Mid-World on a mission to reach a tower that stands in the middle of time and space so he can save his world from devastation. While he's trying to reach the tower, however, so is the villainous man in black, who plans to use the tower to take over the various lands.

The Dark Tower, which stars Idris Elba and Matthew McConaughey, is set to be released Feb. 17, 2017.
