DC and Warner Bros. aren’t really following the Marvel model when it comes to their superhero cinematic universe. Instead of establishing each hero with separate solo films leading up to the first Justice League movie, WB is introducing some characters in Batman v Superman: Dawn of Justice, while others will make their debut in Justice League. But will WB go back and explore the origins of these superheroes after they’ve been introduced in other films?

WB is introducing characters like the new Batman, Wonder Woman and Aquaman in Batman v Superman: Dawn of Justice, while The Flash won’t appear until Justice League: Part One. The studio is taking a different approach from Marvel, which set up their core characters in separate films building up to the first Avengers.

So what’s the deal with WB, then? Will Aquaman’s solo film explore his origins even though he’ll have already been established in two films by then? Collider spoke with Charles Roven, the founder and president of Atlas Entertainment and producer of both Wonder Woman and Suicide Squad. Roven explains that we’ll see these characters progress between Batman v Superman and Justice League, but there’s always the possibility that their solo films could take us back to their beginnings:

The Flash movie or the Aquaman film is gonna come out after Justice League 1, it’s not gonna be a completely different character; that character will have evolved from Justice League 1. Wonder Woman, when we see her in Justice League 1, will have evolved from Batman v Superman. Unless we decide that in one of these stories we’re gonna do something that happened in the past and have it be more of an origination story, in which case you’ll realize how that character became what they were in the movie that they were first introduced.

So it’s not entirely non-linear, but parts of the DCU might be presented out of order. It’s been heavily rumored that the Wonder Woman solo film will divide its time between World War I era and the present, meaning we’ll likely see where Diana came from before she met up with Batman and Superman. And while Justice League: Part One hits theaters in 2017, The Flash and Aquaman’s solo films don’t arrive until 2018.

Justice League will be our first real introduction to these guys (though Aquaman does reportedly have a small part in Batman v Superman) but it likely won’t waste time on offering back stories for each of them. That’s a bold approach, though it’s unclear how much time Zack Snyder plans on devoting to getting all of these characters together in the first Justice League. That alone could easily eat up the bulk of the movie’s runtime.

Roven went on to explain this sort of unconventional approach in a way that sounds like he’s in a “Californians” sketch on SNL:

So that’s really challenging and interesting, and you lay out a road map but then when you bring somebody else in they kinda go, ‘Well you’re going to San Francisco by Route 5, what if you took the 101?’ [And you go] ‘Well that’s interesting, maybe we should go Route 101. What if we did?’ And so that changes the whole thing and all of a sudden you realize you can actually get to where you need to get to by a whole different methodology than what you originally planned. Or you might decide to blend the routes. And by doing that it’s very fresh. You’ve got very fresh ideas, very interesting ideas. It’s just really a lot of fun if you’ve got really great collaborative minds working together to try to make things better, more interesting, more fun, more provocative.

Batman v Superman: Dawn of Justice hits theaters on March 25, 2016, followed by Wonder Woman on June 23, 2017.
