Hmm. I knew this would be a troubled production as soon as the rumors of a Dark Tower movie were swirling around years back. It's just too ambitious a project to produce in such a way where it will a.) be even semi-affordable, and b.) appeal to both fans of the series and the general Summer theater-goer. There's just too much to it to encapsulate in a single film where it can appeal to everyone, its financiers included.
The main catch 22, as I see it, is that to be faithful to the franchise would mean investing a great deal of money into an unproven cinematic property.
...And that could go abysmally (See: Dune -- I absolutely LOVE Lynch's Dune for what it is, mind, but I realize it's basically the poster child of box office failures based on literary works).
...Or it could go brilliantly (See: Lord of the Rings and Harry Potter. However, for every LotR there's a Hobbit, so...yeah. Even a proven property can sour).
So, the movie was in a precarious position from the beginning. They couldn't be too ambitious because the franchise has been pretty far removed from the public consciousness after about 13 years now, since the last book was released, and there's really no telling how the public will respond. And based on what's been said of the test screenings in this topic, the answer seems to be "not real well."
So, it seems they've had to reign the production in quite a bit. Because, if they blow a hundred million or more dollars on a film that brings in a quarter of its budget, or even less, that will very likely mean an end to to not only the property's future cinematic prospects, but a potential end to those involved in its creation. One need only look as far as Michael Cimino's career after Heaven's Gate, and he had The Deer Hunter behind him, which was a critical darling.
In my opinion, for a cinematic adaptation of the Dark Tower series to be truly faithful to the source material, it would almost have to be a series, if the director et al. were hoping to capture the work from beginning to end. I could possibly see it condensed into a trilogy, by shoehorning some of the books together into a movie. But, that would be exuberantly expensive, and as I said before, there's no telling how well it would do since the final book of the series is now thirteen years old. If the books were being released in the same time frame as the movie, as the Harry Potter books were when the films were being made, it would possibly have more series potential, but as it stands, a series would be too financially risky.
So, I guess I can understand why they're doing this weird sequel/reboot/whatever thing they're doing. It can't really be helped. It seems they're basically toeing the water to see if there's further series potential there. If the movie flops, they're only out sixty mil and they can all move on with their lives. But if it does well, then they have at least some proof that the series can sell, which will increase the likelihood of a sequel. It's a fiscally much better situation than spending two or three times as much and having the movie crash and burn at the box office.
The Dark Tower is one of my favorite properties in fiction, so I am still excited to see the movie despite my reservations. I think there's some potential there. I really hope it does well, because the series, in my mind, something truly special.
I was in a fortunate position to be able to start and finish the whole series, from book I through VII, over the course of a summer, after the final book had released, so I didn't have to go through that ungodly wait between The Wizard in Glass and Wolves of the Calla. That said, the ending did come as a gut punch, but it didn't ruin the whole of the journey I'd been taken on.
So, I'm hungry for more Dark Tower...even if the movie crumbles and takes the Tower with it. It will hopefully at least be quite a spectacle.
