The first trailer for the film leaned heavily into tropes and references from Stanley Kubrick's acclaimed adaptation of The Shining, as an adult Danny Torrance revisited the Overlook Hotel decades after the classic story's events.

The rating confirms that Flanagan's film will similarly bring the supernatural scares as Danny finds himself looking after a girl with her own psychic abilities who is targeted by a murderous cult. Judging by the MPAA's rationale for the R-rating, the adaptation is unlikely to pull its punches in terms of graphic content.

Doctor Sleep, which centers on the adult Danny Torrance years after the traumatic events at the Overlook Hotel, stars Ewan McGregor, Rebecca Ferguson, Carl Lumbly, Alex Essoe and Zahn McClarnon. It's scheduled for release on November 8.
