Lightsaber action, words of wisdom, an awesome beard, Obi-Wan can deliver plenty of those and more in this movie.
Ewan McGregor has expressed interest numerous times in playing Obi-Wan Kenobi again, and now’s the perfect time for Lucasfilm to give him a call.
Who knows, maybe there would even be a way to mix elements of the Boba Fett movie and that Tatooine movie into this Obi-Wan Kenobi story so that parts of those projects can still live on, though without taking away focus from Obi-Wan himself.
It’s been 13 years since Revenge of the Sith was released, so he’s the right age to play an Obi-Wan who’s camped out on Tatooine, years removed from when he defeated his former apprentice on Mustafar, but still a ways off from mentoring Luke Skywalker.
