I can’t really imagine an Obi-Wan film set after ROTS without them making up any ridiculous stuff. Sonce he should have been living on Tatooine foe the entire time, I don’t think many would be interested in slice-of-life on Tatooine type of film.
They could just have the plot be about Obi-Wan protecting a settlement from criminals and/or Tusken Raiders or something.
Well, since SW was inspired by Kurosawa’s Hidden Fortress, why not a Yojimbo type film with Ben Kenobi on Tatooine?
I’d watch that, although I doubt it would ever happen.
However, I’m getting the feeling that Disney might be dropping the third anthology film (for now anyway). I’m pretty sure that they’ll make enough money with just the five films planned, and another anthology film after the main trilogy has been finished might confuse people a lot. A lot of people are already confused by the RO teaser. Sure, Disney is out to make back the 4 billion they spent on Lucasfilm, but they are after all making a new Indiana Jones film, so they might use that as a sort-of replacement. It’s scheduled for a 2019 release, so it’d probably be released a few months before ep. IX.
