Ron is a good solid choice. I don’t know if he’s the sort who has a “vision”, but he’s helmed plenty of complicated FX heavy films.
Maybe he can work in a real zero gravity sequence shot aboard the Vomit Comet as he did for Apollo 13.
I’ve always felt he’s a competent and underrated director. I enjoy A Beautiful Mind, Apollo 13, Cinderella Man, and Willow for instance. In fact, his handling of Willow (yes, I know critics didn’t like it much, but I love it!) gives me confidence in his ability to handle a Star Wars movie.
