Long-running rumours about Doomsday being a part of Batman v Superman were confirmed when the deadly DC villain surfaced in the film's latest trailer. Now, in his recent interview, director Zack Snyder revealed that the villain's storyline will tie into the subsequent Justice League films.

While speaking to The Daily Beast about Batman v Superman, Synder stated: "Well, you have Doomsday, right? He doesn't just crawl out of the ground. He has his own mythology, right? So that has to be explored."

The director also hinted that fans may not necessarily see the last of Doomsday in Dawn of Justice. He teased that the villain might have a significant part in the overall DC Cinematic Universe. "To us, it really made sense to give [Doomsday] to the audience now," Snyder said. "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."

That bigger world will eventually see the Justice League come together but before its (Justice League Part 1) November 2017 release, Suicide Squad and the solo Wonder Woman film will expand the stage set in Batman v Superman.

"It is constantly evolving, but we're starting to get a handle on where we're going with the world," said Synder. "That's fun because it allows us now to be driving toward a goal that we don't have to make up as much. The rules can be the rules, and the movie can exist in a closed universe... it allows us to tie things together."

Batman v Superman: Dawn of Justice opens in theatres on 25 March 2016.
