3. A Marketing Nightmare
One of the greatest things about the Dark Tower series is that it defies categorization. Some people think of it as a western, others say its a fantasy, and yet others call it a western-fantasy-sci-fi-action-adventure-horror-romance-literary hybrid. The last one is closest to the truth, as the story explores countless chambers of the mind and heart, leaving no stone unturned. Therein lies its brilliance. Therein also lies a very big problem for the film folks with the big bucks. With no clear category to file the Dark Tower under, studio heads will be pulling out their hair trying to come up with ways to market the film series to a new audience. And that's where the real money is to be found. They can count on the rabid fans (or Constant Readers, as Uncle Stevie affectionately calls them), but in order for the adaptation to be a big enough hit, they need to create new fans. Figuring out how to show them what kind of flick this is in a poster, a still image, or even a trailer, may be nearly impossible.
