regarding Nolan's comments about how he thinks it's best if Batman is the only superhero in the universe, and if Superman is the only one in his own, how it makes them more 'important' to the citizens of the world, etc.... What if they have a multiverse? (Bioshock Infinite is all about this concept, and that's a AAA high-budget blockbuster game. Fringe had it. And each time people say that it's mindblowingly awesome. Nolan's next movie looks like it's going to have it. Is it really as 'outlandish' as people have made it seem? ) Perhaps it puts a new spin on 'assembling the heroes'. Instead of assembling from one world, they are assembled from multiple universes. Mondo epic. That's one way to 1up Avengers, or at least differentiate from it and not feel like a 'me-too' concept. It can also be a way to keep universes tonally different, and thus have the characters' movies/universes be truer to themselves. Ie: WW exists in a universe that has outlandish gods, etc, while Batman's is more grounded and does not have Greek Gods flying around. -- Too complicated? If there's a Flash solo movie prior, perhaps it can introduce/tease the concept, with Jay Garrick coming through to meet Barry Allen or vice-versa; Barry experiencing strange phenomena; people not recognizing him, etc. It could make Flash a unique superhero movie in its own right; the superhero movie about time-travel/alternate universes, etc, all related to his connection to the speed force, while serving as a set up for JL. -- For the JL movie, in Barry Allen's universe (where baby Clark never made it to Earth), The Martian Manhunter arrives with a warning that Braniac has spread across the universe, and is coming for Earth next (coming to learn what Barry Allen has discovered, multidimensional travel, etc, so that it can conquer the next universe once he's done with his own, etc). So Flash quickly reaches out into the multiverse to find Batman for some help (from the Reboot), whose legend seems to have spanned across multiple universes (a nod what Bruce accomplished in TDKT, in a different universe). Batman then forms a plan, and recruits based on specific abilities required to perform a specific task in their mission. He pulls in WW and Aquaman (from the universe where Gods exist), GL (a different one than GL2011's universe, where the Corps also exists), and lastly Superman (from MoS). At the end of the movie, they go back to their respective universes. (it would also solve the 'problem' of why they don't help each other out in their solo movies; Superman's superhearing doesn't span into parallel universes after all) --- The multiverse is also very DC, which would be cool to celebrate in the Justice League movie.
