Two directors that WON't be involved...
Zach Synder is not interested.
Actually, despite his misgivings I bet that he could have done the movie justice.
Quentin Tarantino is not interested.
This is a good thing because, A-- He wasn't going to asked anyway, and B-- as much of a Tarantino fan as I am, I wouldn't want him within a light-year of a Star Wars movie.
