One of the worst-kept secrets in the years leading up to Batman v Superman: Dawn of Justice was that this movie would introduce Aquaman (Jason Momoa), The Flash (Ezra Miller) and Cyborg (Ray Fisher), who will eventually unite with Batman (Ben Affleck), Superman (Henry Cavill) and Wonder Woman (Gal Gadot) in Justice League. Sure enough, all three of those new characters were introduced in unique cameos, and during an interview with IGN, director Zack Snyder revealed why he decided on Aquaman, The Flash and Cyborg to round out this superhero team.

"I thought long and hard about who to bring in, like who the Justice League would be made up [of], and it was really to me like those were the heavy hitters right now. I mean of course, there's room for more, and I had to keep some back for the next little shock of awesomeness. But those guys felt like the guys that needed to surface."

Production begins on Justice League Part 1 on April 11 in the U.K., with Zack Snyder revealing next week that Batman will be bringing these characters together to form the Justice League Fans were given quite the surprise at the end of Batman v Superman: Dawn of Justice, which featured the "death" of Superman, who sacrificed himself to help kill Doomsday, but the movie's final scene teased that Superman is still alive, in one way, shape or form. How he will be resurrected hasn't been made clear at this point, so we'll have to wait and see.

Zack Snyder has made it clear that Batman will be responsible for assembling the rest of these aforementioned heroes in Justice League Part 1, and we assume that he'll be getting some help from Wonder Woman as well. One of the several Easter Eggs in Batman v Superman: Dawn of Justice was the Omega symbol that teases the emergence of Darkseid, one of DC Comics' most iconic villains. Very little has been revealed about the story thus far, but hopefully we'll learn more as production gets under way in just a few weeks.

Justice League Part 1 is shooting at Leavesden studios in southeast England, and will utilize on-location shoots in London and Iceland. Contrary to believe, Justice League Part 2 will not shoot back-to-back with Part 1. But it is staying put on the DCEU release schedule for 2019. It will arrive after solo movies for The Flash and Aquaman in 2018. These movies will be followed by Cyborg, starring Ray Fisher, in 2020 and Green Lantern Corps., which doesn't have any actors attached yet. There is also a rumored Untitled Batman Reboot that will allegedly debut sometime before 2020, to be co-written and directed by Ben Affleck, but that has never been confirmed by Warner Bros. and DC. What do you think about the Justice League lineup?
