HeyUGuys.co.uk got an update from Superman director Zack Snyder, explaining that the ensemble film will not bear a link to either his project or to the upcoming The Dark Knight Rises.
‘It doesn’t [connect]. Like what Chris Nolan is doing and what I’m doing with 'Superman', what they’ll do with 'Justice League' will be it’s own thing with its own Batman and own Superman. We’ll be over here with our movie and they’ll kinda get to do it twice, which is kind of cool."
One key project that seems to be temporarily left out of the equation is this summer's Green Lantern which still could, foreseeably, tie-in to the nascent Justice League film. Likewise, with recent word that WB will reboot the Batman franchise following the release of The Dark Knight Rises, it's still possible that the team picture could build up through cross-released franchise entries, a la Marvel Studios' lead-in to The Avengers.
