Stuart Beattie is the person who came up with the main story for Star Wars: Obi-Wan Kenobi, but left the project and his work moved to the limited series scripts after the box office failure of Solo. In an interview with The Direct, the screenwriter - credited on episodes 1, 2, 3 and 6 - has revealed that the project was initially conceived as a trilogy of films. The first season of the limited series picks up the storyline he had intended for the first one.
"So when I pitched my Obi-Wan story to Lucasfilm, I said, 'There's actually three stories here. Because there's three different evolutions that the character has to make in order to go from Obi-Wan to Ben.' And the first one was the first movie, which was the show, which was, 'Surrender to the will of the Force. Transport your will, surrender your will. Leave the kid alone.'”
Mortality and sacrifice
The second was to deal with the fate of Kenobi: "one of the most powerful and probably the most powerful moment in all of Obi-Wan's story is that moment where he sacrifices himself in A New Hope." However, "if you stop and think about it, it's a pretty sudden thing", so the screenwriter points out that this scene needed something previous, a previous acceptance of what was going to happen.
"it's one of those universal things we all struggle with, to come to terms with our own mortality." This second step in Obi-Wan's evolution is somewhat in response to the teachings of Qui-Gon, his master, when he tells him that there is an instant when he is going to have to sacrifice himself for the sake of others. when that moment comes up in [A New Hope], you understand. He's recognizing he's been on this journey already, and he's waiting for this moment. To me was the second evolution, the second film." Mind that, he says nothing about the plot of the third.
It is rumored that Star Wars: Obi-Wan Kenobi may have a second season. The truth is that Lucasfilm has not ruled it out, although it has been said from the beginning that it is a limited series. Beattie has addressed this possibility. "If I have anything to do with the second season of Obi-Wan, that's the character evolution that I would take him on. That, to me, is really interesting. And like I said, universal."
