Now Hamill has revealed another way Luke changed during the process, going back to his brief scene in The Force Awakens.
As the actor tells it, Abrams was originally going to make that final shot a showing of Luke’s power, which would have likely translated into The Last Jedi.
This seems to have happened when Rian Johnson was handed the franchise in The Last Jedi, killing off characters and changing them at their core in the process.
The most obvious example of this is Mark Hamill’s Luke Skywalker, who was a dark and jaded former hero.
