The film adaptation of Stephen King's 2013 The Shining sequel, Doctor Sleep, hits cinemas on October 31 starring Ewan McGregor as an adult Danny Torrance (from the first movie.)

King disliked Stanley Kubrick’s 1980 adaptation of The Shining as he felt it changed too much of the story. Yet the iconic fiction writer sanctioned elements of Kubrick's version to be incorporated into Doctor Sleep. Mike Flanagan directs the new movie, which stars McGregor as the Torrance character. He has psychic powers and is also battling alcoholism.

"My problem with Kubrick’s film was that it’s so cold," King says in Rolling Stone's report. "The reason I didn’t have any problem with this script is they took some of Kubrick’s material and warmed it up."

The Institute, his new novel, might well prove to be his next Hollywood adaptation, joining The Stand, The Outsider and Lisey's Story, along with the seven movies in development.

The story concerns a group of children with psychic powers who are fighting an evil force. The adults who run the Institute of the title make them undergo medical experiments. "I wanted to write a book like Tom Brown's School Days, but in hell." King says, name-checking Thomas Hughes' 1857 novel about a British boarding school.

The mega-selling novelist has script-approval on all his Hollywood-related projects."The scripts have to work," he says. "They can’t have 19 pages of flashbacks to when the characters were kids. I want the pedal to the metal as much of the time as possible."

The horror writer's next book, If It Bleeds, is due in 2020. The work is a continuation of his ongoing Holly Gibney detective series. It needs is 'a polish', he says. "But it’s basically done." He is already doing the initial work on the book that should succeed If It Bleeds, though he is reticent about it.

"I’m 71 years old," he says, "and a lot of people my age are forgotten and I’ve had this late season burst of success. It’s very gratifying."

Retirement is 'God’s decision, not mine," says the best-selling author. "But I’ll know when it’s time. I’ll either collapse at my desk or the ideas will run out — the thing you don’t want to do is embarrass yourself. As long as I feel like I’m still doing good work, I can’t see myself stopping."
