“There were two key things Trevorrow wanted to be changed – and they were not minor”, claims the rumour. “These two things have been known for a while around Disney. Firstly, he wanted Luke to still be alive in 9. He strongly disagreed with killing Luke off in 8 when he had just been re-introduced. Luke and Leia were to be a pivotal part of his script, with Leia’s Force affinity revealed in a much more brother/sister way that was apparently going to be ‘beautiful and tragic’. Mark Hamill loved it. ‘We were on the same page,’ as he’s said about Trevorrow’s storyline. However, Kennedy and Johnson wanted Luke dead – period. Second, he wanted Snoke to live, as his back story was to be more discussed. Fisher dying scuttled his original plan for the Leia Force affinity reveal, of course. But he still needed Luke alive for the story he wanted to tell to end the trilogy – more of a Luke handing off the baton to Rey and a Luke ‘walking off into the sunset’ idea, in the last film – rather than Luke dying in 8. They refused. He argued. They fired him.”
