The Stephen King adaption guy? He done anything that'd really fit the Star Wars sci-fi action mould at all, that also was good?
I gave several reasons above on why I think he'd be a perfect fit. Someone doesn't have to have had experience making a similar movie to possibly be good at it.
But on that note, I also realized one possibility that I'm surprised isn't one fandom is jumping on, as I would expect it to, but who I think are actually really well suited to it...
...are The Wachowski's.
