Batman V Superman: Dawn of Justice is now in theaters, and with the movie pulling in loads of box office cash despite some less-than-stellar reviews, there is no doubt that Warner Bros. will be moving full-speed ahead with the Justice League movie that Batman V Superman sets up.

In addition to Batman and Superman themselves, Batman V Superman features another Justice League member’s debut with the introduction of Wonder Woman. Flash, Cyborg, and Aquaman are teased as well, although they do not enjoy the screen time that Wonder Woman getsWhile that would be a pretty impressive team in and of itself, Batman V Superman and Justice League director Zack Snyder has now hinted that the roster won’t end there.

In the interview with IGN below, Snyder talks about the world-building aspect of Batman V Superman and how he decided which Justice League members to include:

“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.”

There are, of course, many DC superheroes who have come and gone from the Justice League in the comics and cartoons; for instance, Hawkman and Hawkgirl, who appear in The CW’s Legends of Tomorrow but have not yet made their way to DC’s cinematic universe. There is also Shazam, who is scheduled to appear in his own standalone movie in 2019 (or perhaps earlier, according to its star, Dwayne “The Rock” Johnson). That would be well past the release date of the first Justice League movie, but that doesn’t mean he couldn’t appear in Justice League first. Green Lantern is still missing from the lineup as well, and his addition to the movie could at least have the potential to make Tyrese Gibson very happy.

Like Marvel’s Avengersthe scope of Justice League is really only limited by how many heroes can fit into a single movie before it becomes incoherent. With Batman V Superman, Snyder has proven that he can make a superhero movie that is epic in scope, even if it is not to everyone’s liking. Just how epic Justice League will end up being remains to be seen, but hopefully Snyder makes good on his promise of “shocks of awesomeness” to come.

Batman V Superman: Dawn of Justice is now playing in U.S. theaters. Suicide Squad will arrive on August 5, 2016, followed by Wonder Woman on June 23, 2017; Justice League Part One on November 17, 2017; The Flash on March 16, 2018; Aquaman on July 27, 2018; Shazam on April 5, 2019; Justice League Part Two on June 14, 2019; Cyborg on April 3, 2020; and Green Lantern Corps. on June 19, 2020.
