He may also be in protracted silence if he is negotiating on a new Dresden Files show with someone like Disney or Amazon or Netflix, and we suddenly see him everywhere promoting that. I think of the recent Amazon Jack Reacher series which popped up out of nowhere seemingly. Given the tug of war over his creative input on the Blackthorne series you have got. It’s been 15 freaking years now that this major IP has not been on screen.
This would be amazing, and I've wondered about it. It would certainly be pretty awesome to see a modern production of a Dresden Files show. I could see 4 to 6 episodes per book, with 2-3 books per season. Season 1 is first three books (3, 3, 4 episodes), Season 2 is next three books 12 episodes (4, 4, 4 episodes), and subsequent seasons are two books (they get longer in word count) per season at 5 episodes per book. It'd be 12 seasons to get through everything, which is a LONG time, but that would give actors time to age (the timeline would still have to be compressed) and Jim time to write the remaining 8 or 9 books... (Or maybe not, considering current production.)
Something like that would be absolutely incredible.
