3 Days ago, screenwriter David S. Goyer has claimed that Man of Steel 2 would open a floodgate of DC Comics superheroes, and would be the stepping stone for the Justice League movie.
Basically we will either see a new Batman(one which isn’t connected to TDK trilogy), or Wonder Woman introduced in the upcoming sequel.
“It would be disingenuous to say Warner Bros doesn’t hope that this would be the starting point for a shared universe. And [Zack] Snyder has said that Bruce Wayne exists in this universe. It would be a different Bruce Wayne from Chris’ The Dark Knight trilogy, and it would be disingenuous to say that Zack and I haven’t had various conversations on set, around ‘what if’ and ‘moving forward’. That having been said, it’s all going to depend on the next few weeks. Warner Bros has hopes that there will be more Man of Steel films, and that this will be the beginning of a shared universe. We could meet Batman, or Wonder Woman, or the Justice League in these movies. But they all hinge on box office reception. If that happens, I would be happy, and nervous, to dive in.”
David S. Goyer also confirms that new screenplay in progress, though careful not to confirm himself as the author.
“They’re hoping that the film does well, but god forbid it doesn’t, things will change. I don’t know how many different iterations of Justice League they’ve tried to mount over the last decade or so. But for one reason or another they haven’t happened. I think Warner Bros has seen, and Christ[opher Nolan] deserves the biggest credit for this, that we were able to revitalize Batman and put it into the first billion dollar superhero film. And they’re hoping that Superman will be revitalized as well. And if we can do Batman and Superman, then maybe we can move on to Wonder Woman, and The Flash, and characters like that.”
