David Goyer was suppose to adapt the book to the screen of the movie "Descent". Here is the description of what the story is about: A well received book crossing the science fiction and horror genres, if you haven’t heard of it, the story centers on a scientific expedition’s work to tunnel six miles into the earth, and the trouble they find after… well, what’s the title of the novel? The trouble they find are creatures who gave rise to the popular myths of Hell. I guess it is not looking good for this movie. Since this info was from last year and the IMDB has absolutely nothing on this. Has anyone heard something?
