Mike Flanagan spoke to Script Apart Podcast about his ideas for The Dark Tower and it turns out he want to add characters from The Shining and Doctor Sleep to The Dark Tower universe.
“Abra Stone in the Dark Tower universe, as a Breaker [telepathic agent], is really interesting,” he says. “There’s a character in The Dark Tower named Dandelo, who I think is a cousin of the True Knot, who’s this emotional vampire but who feeds on laughter instead of fear. But there’s room in that world for the True Knot themselves, there’s room for Rose The Hat. There might be room for Danny Torrance.”
What do you think, should Abra, Danny and Rose The Hat be in The Dark Tower adaptation? Personally I don’t think so. They are fine in their own world and not everything King has written are connected to The Dark Tower.
