Right now, we're less than two years away from a Batman and Superman team-up, the kind of geeky synergy that many thought would never happen. Because it's not like DC hasn't tried it before.
The tentatively titled "Batman Vs. Superman" is the second attempt at that specific team, but there was another project in 2007 that would have brought together the entire Justice League, something that still might be years down the road for this current "Man of Steel" iteration.
That version was to be directed by "Mad Max" mastermind George Miller, and it was set to star Armie Hammer as Batman, Megan Gale as Wonder Woman, D.J. Cotrona as Superman, Adam Brody as The Flash, and Common as John Stewart.
The script for that project has recently leaked online (via Superhero Movie News), and it provides an interesting look into an alternate universe where that project didn't fall apart in the development phase.
The year that the project was taking shape, 2007, is worth noting because it was right around the infamous WGA writers strike that resulted in a number of half-formed films, like "Quantum of Solace" and "Revenge of the Fallen."
And as some who have read the script for "Justice League" are pointing out, the screenplay by Kieran and Michele Mulroney also suffered from the strike, claiming that the treatment isn't very good at all.
The story follows Superman, Batman, Wonder Woman, Green Lantern, Aquaman, The Flash, and Martian Manhunter as they struggle with their own superpowered interpersonal relationships and the spy satellite that Bruce Wayne installed to spy on them.
