The Last Jedi writer-director Rian Johnson talked about George Lucas during a press conference in France (at 8:44).
“I had a conversation with Lucas at the beginning of the process. It was just very general. He was very supportive. He wasn’t involved in the process of actually making the movie. I went to USC, the film school I went to, because I’ve read a book about George Lucas. I grew up with him as a hero in my mind.”
