I know that you are avoiding almost everything about the prequels and, quite frankly, I can’t blame you. They were not that good but you did promise to make them part of the canon so you are quite stuck with those films as Episodes I to III.
All is not lost as it at least gives you access to the wonderful Ewan McGregor, whose Obi-Wan Kenobi was one of the best parts of the prequel trilogy. Even better, McGregor is absolutely willing to reprise the role in not one, but at least two films.
“I’ve always thought there was a story to tell between my last one and Alec Guinness’ first one. It would be fun to film that story now I’m older. I’d be the right age. I’m forty-five, Alec Guinness was what, sixty? I could do two of them (laughs)! I hope that they’re going to explore different genres under the Star Wars banner. And one of those could be an Obi-Wan Kenobi feature film. Or two! The Obi-Wan Kenobi Story Part 1 and Part 2!”
I’m not all that happy for the way the prequels turned out, so I think Star Wars owes it to McGregor to put him in a great film. It should also be noted that Liam Neeson also wouldn’t mind reprising his role as Qui-Gon Jinn, so having him in the film as a Force ghost would also be pretty great. He has already lent his voice to the Star Wars: The Clone Wars animated series, so he seems to really like being part of the Star Wars universe.
The only thing that might make fans pause is Obi-Wan is looking out for Luke Skywalker the entire time. Although it could be pointed out that it doesn’t mean Kenobi hung around the desert exclusively for nineteen years, and may have travelled to other planets during this time.
While we’re on that subject, we might as well point out that Uncle Owen seemed to grow a dislike of Obi-Wan between Revenge of the Sith and A New Hope, so they might as well bring back Joel Edgerton to reprise that role, and we can find out why.
Even if that doesn’t happen, we will almost certainly see Obi-Wan pop up again on Star Wars Rebels. The last episode, “The Antilles Extraction,” seemed to indicate that Darth Maul learned Obi-Wan is still alive, so I suspect we will see a rematch between the two — sounds like a season finale episode to me.
