I don’t think you’ll have to worry.
First off, I thought that was a particularly funny post because I wrote the description of Hades in my books before Adam Driver was a known actor.
Second, and I’ve said this before, I don’t have any authoritative final say over casting, ultimately, but I’m pretty confident that a brand new show can’t afford the salary of anyone who was in Star Wars.
Think Game of Thrones… there was one actor who was relatively well known to anchor and carry the first season (Sean Bean). All the actors who are now household names are known because they came up through the popularity of that show. Sophie Turner, Kit Harrington, Jason Momoa, Maisie Williams, Emmelia Clarke… their current fame and continuing careers are largely resultant of Game of Thrones.
I imagine that Pawns of Olympus will be the same way.
