If it's crap ... We'll tell you
I won't deny, I would be interested in seeing him direct just to see what the finished product would be, but in terms of possible-quality, I'm thinking Takashi Miike, Duncan Jones, or Rian Johnson are easily the ones with the most potential.
By giving Miike the Director's chair, you might as well let David Cronenberg direct. For a kid's film like Star Wars, I'm certain many of us fans don't want to see that.
Then again, David Lynch made "Dune" so anything is possible.
David Lynch rejected George Lucas' offer to direct Return Of The Jedi, saying as his reason that, "I didn't, and still don't understand what Star Wars is all about". I'd think Kathleen Kennedy would learn from Lynch and Dune.
Considering that Star Wars is essentially a Samurai film series set in space, with Miike doing a really good Samurai flick with the 13 Assassins remake (and, going off of RT, he did a fine remake of Hara-Kiri), and is incredibly diverse as a director (he doesn't do just disturbing shit, y'know), that his range and unpredictability as to what he'd bring to the table would be his greatest asset. Most potential overall.
Just stick with Jones and Johnson.
Duncan Jones would be great directing Star Wars, I agree. I think out of any director, he'd work best with the material, judging from his first two films.
If he makes it as fetishistic as 300, Watchmen, or Sucker Punch, I'd certainly see it.
I'd be really interested in ANYONE directing Star Wars Episode 7.
And that's not a jab at George Lucas, I just think it'd be cool to see anyone's vision of the universe.
I'm fine with him directing, but not if he's writing (Sucker Punch proved he needs outside help with scripts)
Duncan Jones, or Rian Johnson
Those are some damn good choices! I would even suggest Neil Blomkamp for the director's chair.
I wouldn't suggest Blomkamp, if only for the reason that I don't want to see a Science Fiction allegory for political shit. If you watched Attack Of The Clones, the absolute worst Star Wars movie, you could tell where most of its shit came from.
With Johnson, Looper felt like something maybe pre-Schindler's List Spielberg would do, whereas with Jones, I'm excited as all hell for Mute.
you do not want to see a science fiction allegory for political shit? thats what every Star Wars film is along with a good peppering of religious shit.
