JJ Abrams. I know he only produced Cloverfield, but I loved that. Lost was one of the best boxsets I've worked through and the Star Trek reboot was much better than I expected. He is my fave US director now, as David Fincher seems to have lost it these days.
Christopher Nolan. The Batman trilogy, Inception, Memento and The Prestige are some of the best modern day movies imo. He would be my top pick to direct all three. Couldn't imagine Hans Zimmer doing the Star Wars music though lol.
Both of these guys keep getting mentioned. Danny Boyle might be good as well.
