New interview with Rian Johnson:
"Is there an overarching plot for where the trilogy goes? You obviously have The Force Awakens as a jumping off point, but is there a place you need to get to, in order to set up J.J. Abrams’ Episode IX?
RJ: Not really. That’s what’s been really cool about the storytelling process. There is definitely the idea that we know it is a three-movie arc. We know the first film is an introduction, then the middle act is training, meaning challenging the characters. The third is where they all come together and you have to resolve everything.
But I was truly able to write this script without bases to tag, and without a big outline on the wall. That meant I could react to what I felt from The Force Awakens, and what I wanted to see. I could make this movie personal. I could also just take these characters where it felt right and most interesting to take them. I think part of the reason the movie feels like it goes to some unexpected places with the characters is that we had that freedom. If it had all just been planned out and written down beforehand, it might have felt a little more calculated, I suppose."
