There’s still a long way to go before “Batman v Superman: Dawn of Justice” leads to an expansion of the DC Comics universe. Despite the film’s having been teased since 2013, it is only now that one of the cast members involved in the bout between heroes is revealing why the two good guys are even squaring off in the first place.

Fans have known for a while that Henry Cavill’s Superman from “Man of Steel” will be going toe-to-toe with Ben Affleck’s Batman (aka Bruce Wayne) in the 2016 flick. In a recent interview with Total Film magazine, Cavill explained how the movie’s opening scene will set up the conflict between the two often-allied superheroes. 

“What happens there is one of Bruce’s buildings gets destroyed and he’s trying to save all the people inside the building and he can’t,” Cavill said (via ScreenRant). “So he is this angry person who fears what Superman may do. Why are they just going to trust this superpowered alien? What if he does decide to turn against us?” 

This moment was foreshadowed in the first full-length trailer for the film, which saw Affleck’s Bruce Wayne character running through the streets of a city where chaos had broken loose. Although it’s unconfirmed based on the trailer alone, it’s heavily implied that the scene is a flashback taking place during the destruction of Metropolis in the canon movie “Man of Steel.”

When the film came out in 2013, it was criticized by audiences for its final fight sequence, when Superman and Zod (Michael Shannon) wound up destroying half the city and presumably were responsible for countless deaths. “Man of Steel” didn’t really address the repercussions of that incident, which director Zack Snyder said was the result of a conscious effort to raise the stakes in “Dawn of Justice.”

“I was surprised because that’s the thesis of Superman for me, that you can’t just have superheroes knock around and have there be no consequences,” Snyder told Entertainment Weekly

Fortunately, it looks like those consequences will be coming for Superman in “Dawn of Justice” in the form of an incredibly angry Batman, who will be bent on stopping this new alien threat in an attempt to prove that human beings still have control of the planet.
