The appalling fact that RON HOWARD is directing seems to have eluded everyone here. Good on you for being optimists.
Just a few highlights from the man's back catalogue:
Da Vinci Code
Frost/Nixon
Cinderella Man
A Beautiful Mind
The Grinch
EdTV
Apollo 13
Backdraft
Willow
Now I dare say there's probably some films in there that one might begrudgingly call 'OK.' But from a purely tonal, generic and thematic point of view, who the hell looked at that list and thought, 'Perfect for Dark Tower'!?
I can't see this being anything but a failure. The books border on unfilmable anyway. Part of their charm lies in being a King metaseries, and how is that going to work on screen? I also have very good reason to believe that a lot of King's dialogue in the series, whilst perfect in the literary world, would be virtually unspeakable for an actor. And if you have to change the dialogue you're losing a lot of the original charm of the series.
Couldn't Chris Carter be considered? I'm not saying his back catalogue is any less cheesy, but at least he's in the right genre. Better yet, get the guys behind Deadwood or Carnivale involved.
