The director of the recent Dune movies, Blade Runner 2049 and Arrival revealed in a podcast, why he has no interest directing a Star Wars movie:
“I was the target audience. I was 10 years old. It went to my brain like a silver bullet. I became obsessed with Star Wars. I mean, The Empire Strikes Back is the movie that I anticipated the most in my life. I saw the movie a billion times onscreen. […] I adore Star Wars. The problem is that it all derailed in 1983 with Return of the Jedi. […] I was 15 years old, and my best friend and I wanted to take a cab and go to L.A. and talk to George Lucas — we were so angry! Still today, the Ewoks. It turned out to be a comedy for kids. Star Wars became crystallized in its own mythology, very dogmatic, it seemed like a recipe, no more surprises. So I’m not dreaming to do a Star Wars because it feels like code is very codified.”
