After several potential iterations and many years of waiting, the film adaptation of Stephen King’s The Dark Tower is finally arriving in theaters in less than two months. Idris Elba and Matthew McConaughey star in the Nikolaj Arcel-directed film, which Stephen King has given his personal blessing to.

In an interview with IGN, Arcel just revealed exactly what King wrote to him after seeing the completed film, and he also noted that King provided some notes during the scripting process.

“At one point he had, ‘I have some notes for script.’ And he sent us a hard copy of the script, with hand-written notes,” Arcel recalled. “He was very polite and very respectful. It was always like, ‘Maybe Roland doesn’t talk so much here’… he was just like the groundskeeper of the characters.”

He added, “After he saw the film for the first time, [King wrote to me], ‘This is not exactly my novel but this is very much the spirit and the tone. And I’m very happy.'”

Arcel also revealed that The Dark Tower is not a direct adaptation of any of the books in the series, but rather a “canon continuation” of the story in the novels.

Fran Kranz, Jackie Earle Haley, Abbey Lee, and Kathryn Winnick also star.

The Dark Tower was directed by Nikolaj Arcel and produced by Akiva Goldman, Ron Howard, Brian Grazer, and Erica Hughes.

Look for it on August 4, 2017.
