I read that earlier this afternoon. I think it would be interesting to explore Obi-Wan Kenobi's story after the events of Revenge Of The Sith. And I think Ewan McGregor is a really good actor, too. In fact, I just finished watching his documentary series "Long Way Round" that he filmed shortly after production for Revenge Of The Sith wrapped production.
I think there have been times where it's been cool to hate on Star Wars. But I think in the case of Ewan McGregor he went into the experience of making the prequels with the expectation that it would be like the OT with these fantastic sets. But the reality of making the PT was that a lot of the work was done in front of blue and green screens. From the perspective of an actor I can imagine that could be a little demoralizing. You're expecting to be able to immerse yourself in this otherworldly place that informs your performance, but then you're standing on some decorative floor with a bunch of green screens around you.
The approach that J.J. Abrams is taking with the practical effects and sets have to be a much more enticing situation for the actors. Mark Hamill went into this saying that he would be far more interested if the sequel trilogy films incorporated physical sets and practical effects. And now these actors get to immerse themselves in the world of Star Wars as they might have hoped to when they saw the original films. Plus, in the case of Obi-Wan Kenobi? There are rumors that there are echoes of his past that pop up in the new Sequel Trilogy. And some discussions have even gone so far as to mention a resolution to the Darth Maul story arc in just such a project. Perhaps something that even draws from that Visionaries graphic novel. So I think a Star Wars Anthology film that follows Obi-Wan Kenobi might resonate further than the one individual film.
