What I'm looking for out of the director is someone who can match the tone of the original trilogy. I want this to be a return to glory for the franchise. I want it to be fun adventure, I want there to be warmth in the acting, I want it to switch effortlessly between genuinely funny dialogue and mythic seriousness. I don't want SW to change to fit the director.
Exactly. Tim Burton, Chris Nolan, David Fincher (and his bloody teal tint)--all these would be poor choices. You want someone like Irvin Kershner who has a sensitive, fun and intelligent style without intruding into the look of the film.
My concern with Spielberg is that his DP, Janusz Kaminski, would make it look too clinical.
