A script based on another of his stories,
“Understand,” is also in development.
How in blazes do you make a movie of a story that happens almost entirely in the guy's head? And what on Earth did they do to the ending to make it mainstream-palatable? That said, I sort of feel like the author buried the lede, with this one. It's one of my favorite stories, and I hope they do it justice.
[Mild spoilers ahead] There's the drama of the initial accident, then the recovery. Stealing the vials. Pursuit by the government agency. Locating the opponent, and the final conflict between them. Plenty to work with there, I think.
The challenge, as you say, would be to do justice to the story and not turn it into some kind of car-chase/superhero mess.
