His pay might be at stake, after all you do want to continue acting in next episode. Don't forget, he was on the same page of how Luke was supposed to be with the former director.
First reaction is normally the correct one. I don't blame him for retracting.
Disney being confident on Rian's Trilogy, may be a bad one. To me, is how his editing and story telling that actually is the problem. TLJ can pass in story, is the editing and how the story is being told has failed. But hey, I am just an audience, we vote with our wallets. ATM is how episode nine concludes, it decides for me, whether I like this trilogy at all.
Someone explain to me How Rian J was picked to do TLJ? I thought he has no experience at all with Sci Fi? All he did was Looper?
I mean look at JJ, that I can understand why he can touch Star Wars, But Rian? Looper? urm how the heck he got this?
