Hidalgo wrote, “years before The Last Jedi began development, the treatment left behind by George Lucas in 2012 also had Episode 8 be the one wherein Luke Skywalker would die.” So, that doesn’t mean that Lucas would make the exact same decisions, but it sounds like the Jedi wouldn’t have made it to the end of the Skywalker Saga unscathed.
Mark Hamill has been asked about his read of Luke’s ending endlessly since The Last Jedi hit theaters. The actor tried to maintain a balance and perform but made it very clear that he didn’t agree with the decision.
"I said to Rian, 'Jedi's don't give up.' I mean, even if [Luke] had a problem, he would maybe take a year to try and regroup, but if he made a mistake, he would try to right that wrong, so right there, we had a fundamental difference," Hamill shared of his initial reaction to the script. "But it's not my story anymore, it's somebody else's story and Rian needed me to be a certain way to make the ending effective. That's the crux of my problem. Luke would never say that. I'm sorry."
"Well, in this version...see, I'm talking about the George Lucas Star Wars, this is the next generation of Star Wars," Hamill observed. "I almost had to think of Luke as another character. Maybe he's 'Jake Skywalker,' he's not my Luke Skywalker. But I had to do what Rian wanted me to do because it serves the story well. Listen, I still haven't accepted it completely, but, it's only a movie. I hope people like it. I hope they don't get upset. I came to really believe that Rian was the exact man they needed for this job."
