Much has been revealed about next year's "Batman v Superman: Dawn of Justice," the follow-up to 2013's "Man of Steel" that kicks off the rapid expansion of Warner Bros.' shared DC film universe. We've seen stills as well as behind-the-scenes pictures and even learned a bit more about how "BvS" connects with "Suicide Squad."

Even more DC details have emerged via the "BvS"-centric issue of "Empire," which ComicBookMovie has transcribed. This time the quotes in question pertain to the wider "Extended Universe," as the WB is referring to it, and the upcoming "Justice League" team up films.

"What we are doing is ground up all the way," said "BvS" and "Justice League" director Zack Snyder. "It is one giant story. The first thing we had was the Justice League concept. The other movies, in a way, have to support that. That is our Wonder Woman, our Aquaman. They have their own creative concepts that supports them, but they do serve 'Justice League' in the coming together of those heroes."

Many of those films already have directors attached; David Ayer is currently shooting "Suicide Squad" while Patty Jenkins will direct "Wonder Woman" and James Wan will helm "Aquaman." Snyder spoke to how he's working alongside those directors to help bring this "extended" universe to life.

"I want all the other directors of the other films to be able to stretch their legs and do what they want, but at the same time there is a big interconnected universe," said Snyder. "I have given everyone amazing access to our story, to me, and what we are doing. All the films have like minded conceptual jumping on points."

"Batman v Superman" producer Charles Roven likened the methodology to a sandbox. "It has borders around it, but everybody gets to play in the sandbox," said Roven. "On 'Suicide Squad,' David Ayer has a lot of specific control over his area of the sandbox. Even if he crosses the line a little bit, we see if we can push our boundaries back a little bit."

Fellow "BvS" producer Deborah Snyder mentioned in the article that there is an official, internal "timeline of what every movie is, where it is going, and where the films fit in relation to each other."

"Batman v Superman: Dawn of Justice" opens on March 25, 2016. "Justice League Part One" is scheduled to open on November 17, 2017.
