its funny you mention these things Zombie because I also think despite his dedication to cutting edge technologies, there isn't a filmmaker more poorly suited for 21 century filmmaking. Its not just art-house and serious dramas that demand strong actors, directors and storytelling - people want these from blockbusters as well (except maybe transformers, lol. but how the hell does michael bay continue to get such great casts!?)
thing is, and correct me if Im wrong, lucas does NOT live at skywalker ranch. He lives in San Rafael. so he is not cut-off from civilization. he just dislikes people unless they are sycophants.
As for him saying that films are cut and modified without directors consent - well, I hope for his sake there is no truth to the rumor that the director of red tails was fired and lucas took control (I don't buy for one second that those were just normal reshoots and pickups).
