Despite being just a few months away from hitting theaters, there's still a lot of mystery surrounding the villains and conflict at the heart of "Batman v Superman: Dawn of Justice." There's the titular match-up between superheroes Batman (Ben Affleck) and Superman (Henry Cavill), of course, but there's also Lex Luthor (Jesse Eisenberg) and the real wildcard, Doomsday. The most recent trailer for the film revealed that the massive alien warrior will play a role in the film, most likely as a threat created by Luthor using the corpse of General Zod. But there might be more to Doomsday, as director Zack Snyder revealed in an interview with The Daily Beast.

Snyder mentions that there was a "long conversation about just taking ownership of" Doomsday's reveal, and putting it in the trailer "in a controlled way that I felt was consistent with the escalation of the campaign." Snyder also followed up on a quote he gave in a previous interview that posited that there will be bigger threats out there for the Justice League to face in their upcoming team movie.

"Well, you have Doomsday, right?" said Snyder, playing coy when asked about the kind of bad guys the Justice League might encounter. "[Doomsday] doesn't just crawl out of the ground. He has his own mythology, right? So that has to be explored..."

Doomsday's involvement also implies a larger world than what we've seen so far. "To us it really made sense to give [Doomsday] to the audience now. I really wanted to make the audience a promise that... though I'm super excited and happy and fulfilled by the conflict of Batman and Superman, there's also a bigger world to start to think about."

While the rules of the newly-formed DC movie-verse are "constantly evolving," Snyder notes that the brain-trust behind the shared universe are "starting to get a handle on where we're going with the world."

"It allows for a coherent universe, which is important," he added. "I think that makes the experience a little more satisfying because we know where we're going, so the misdirects can be stronger and the reveals can be bigger."

Directed by Snyder and starring Henry Cavill, Ben Affleck, Gal Gadot, Jesse Eisenberg, Amy Adams and more, "Batman v Superman: Dawn of Justice" opens on March 25.
