I keep thinking how great this would work for a Huge story like Stormlight.
You run each character as an HBO season and then after each season release the movie. So season 1 is Kalidins back story and the first movie starts with him in the slave cart. Second season shallan and so for forth. I get that a lot of the book story telling goes hand in hand backstory/present, but, I feel that could be tweaked to work.
Now it obviously couldn't be 1 season / movie a year, but if you did a season in conjunction with the movie release, it would still be really cool.
Anyways... Just random thoughts. Cheers!
