Who would you want directing a Justice League movie?

[Sussudio]

With the recent news that George Miller was supposedly confirmed as off the Justice League project, then back on, and to the disappointment of many people that he was even approached to direct it, who would you feel comfortable handing the reigns over to should a Justice League movie ever enter major development (if without Miller)? Someone that has already directed a super hero movie? A newcomer to the genre?

nolan is unquestionably my first pick (although he would never do it), but i think alex proyas might do an admirable job. or for something truly epic maybe james cameron. i've always wanted to see him attempt a superhero movie, but he'd never do it either (even though i know he was in talks to direct spiderman)
