ObiWan no one knows what this movie will be except DC ENT execs, Chris Nolan, Jonah Nolan, and David Goyer! What was posted in the original article is purely speculation. That is all we have on this movie yet. The only thing we do know that seems to be confirmed is that the film will be shot in Vancouver
There is nothing confirmed or known about the plot, casting, who will be composing the film, etc. It was reported a month or so ago that Zack will be getting more hands on with this project once he wraps up his commitments for "Sucker Punch" which should be soon since he's been in post-production for a while now. I suspect we'll be hearing significant news about this film (including the title which isn't known yet either) sometime in the new year, maybe as soon as next month.
