Right, so here are my choices.
Cycle of the Werewolf - I've long maintained that this is one of the few SK adaptations that deserves a remake. What they need to focus on is the aesthetics, which would blend right in with the book's theme of changing seasons. You want a limited series with a gorgeous, distinctive look? Put Bryan Fuller in charge of it. Look at his Hannibal TV series for reference, as well as American Gods. And the werewolves MUST be practical effects (with just the right touch of CGI embellishment), designed to look like the Wrightson drawings. Drag Rick Baker out of retirement for this one.
Duma Key - a fantastic book with a whole lot of story that deserves a limited series over a two hour film. Bryan Cranston's always been my pick for the lead, as he has the right blue-collar appeal for the main character. After watching Godless (Lord how I loved that show), I'd also throw Jeff Daniels in there for the lead or Wireman.
Firestarter - I don't mind a remake, but it will draw inevitable comparisons to Eleven's story in Stranger Things. Still, the movie wasn't a good adaptation, so I wouldn't mind a revisit.
Here are some thought on the other choices.
The Talisman - the best HBO series that HBO hasn't optioned as yet.
The Stand - it's currently being developed by Josh Boone. He was kind enough to show up on this forum to share some info on the project, including correcting some misinformation I had posted (based on an old article I read). I'm very interested in seeing what he has planned for us.
Joyland - would be perfect for a done-in-one Netflix film.
Needful Things - wouldn't mind a series, but it's not high on my wishlist.
The Tommyknockers - didn't like the book enough to want to see another adaptation.
From a Buick 8 - didn't enjoy the book, not interested in a film.
Christine - as much as I liked the first film and acknowledge that it left out a fair amount of story, I'm not sure how another adaptation would work. It's hard to see anyone taking a haunted-car story seriously now, so they'd probably have to go full-retro on it and make it an 80s-film. I can't see Christine working in this age of social media, cell-phones and information-overload. That said, I think Carpenter's film is a such a wonderful little rock n' roll nugget in the horror genre (story shortcomings and all), and no CGI will ever replace that incredible scene of a car on freaking fire and chasing that dude down the street. That scene still blows my mind every time I see it.
Doctor Sleep - regardless of platform (cable tv, film), I've always wondered how the heck this will work. It's a continuation of Danny's story in The Shining yes, and will no doubt be marketed as a sequel, but sequel to what? Kubrick's film, that one that King famously hates and takes huge liberties with the story, or Garris's mini-series, a faithful retelling hampered by some questionable casting (I'm looking at you, annoying little kid) and pacing issues? That's a conundrum right there. John Cusack has openly expressed his interest in playing the adult Danny, by the way.
