This idea has been pined over for many years here on the forum. I believe the material has been optioned several times, if I'm remembering correctly what Dan has said. Most recently Bradley Cooper was going to write a screenplay for it, but that never got anywhere, and Dan may have the rights back again (and may have already optioned them off again for all I know).
I think more diagnostic of what may happen with other of Dan's works is the success of THE TERROR. The entire run of ten episodes is now streaming on AMC, according to an email I received from AMC this morning, so that should bring even more eyes to his work, and hopefully convince someone to make more of his books into movies or television. If I were Bill Gates-rich, I would find a way to make it happen myself, starting with CARRION COMFORT, and then moving on to either Hyperion or Ilium-Olympos, another personal favorite. And then, for those who aren't quite so interested in speculative fiction, he has several wonderful historical fictions (DROOD, THE FIFTH HEART, BLACK HILLS, THE ABOMINABLE, etc.) You could make an entire career as a producer out of his body of work, and every work unique.
