Just how far in advance is this overarching Star Wars saga planned out? Episode VIII, The Last Jedi, is on post-production now and headed to theaters this winter. Episode IX is in development, building off the events of that film. So how much of Episode VIII was set in stone, and when, to give Episode IX enough time to be fully developed and fleshed out? And is that movie setting the stage for an Episode X, and so on and so forth? These are the questions a man thinks to himself when he writes on the interwebs all day.
