“Speaking to IGN about the differences in approach to the character of Luke Skywalker between J.J. Abrams and Rian Johnson, [Mark] Hamill suddenly changed tack, and explained:
“I happen to know that George didn’t kill Luke until the end of [Episode] 9, after he trained Leia. Which is another thread that was never played upon [in The Last Jedi].” […]
More generally, Hamill compared the approaches between Lucas and Disney’s Star Wars films:
“George had an overall arc – if he didn’t have all the details, he had sort of an overall feel for where the [sequel trilogy was] going – but this one’s more like a relay race. You run and hand the torch off to the next guy, he picks it up and goes.
“Ryan didn’t write what happens in 9 – he was going to hand it off to, originally, Colin Trevorrow and now J.J. […] It’s an ever-evolving, living, breathing thing. Whoever’s onboard gets to play with the life-size action figures that we all are.” […]”
