During an interview with CinemaBlend, producer Charles Roven has been talking about the timeline of the DC Extended Universe, and more specifically where Aquaman fits into things. Unlike the DCEU’s first post-Batman v Superman: Dawn of Justice origin story Wonder Woman, the film will take place primarily after the events of November’s Justice League, although that may not necessarily be the case for all DCEU movies going forward.
“Aquaman will make reference [to Justice League],2 said Roven. “There will be some reference of something that preceded Aquaman that will be in Aquaman. I believe that is the intention. James Wan definitely knows where he’s going with [Aquaman], and that movie takes place in a world where Justice League happened, and Man of Steel happened, and Wonder Woman obviously takes place before Man of Steel — except for the bookends we have. So that’s where we have the most ability to freeform. We could do a movie that takes place after Justice League, we can do a movie that takes place after Batman v Superman… well not really. You can’t do a movie in between Batman v Superman and Justice League, but we can do movies that take place after Justice League and we can do movies that precede Justice League.”
Aquaman won’t entirely take place after Justice League however, as we have already heard that a young Arthur Curry has been cast, meaning we can expect some kind of flashbacks in the film.
Aquaman is being directed by James Wan (The Conjuring) and stars Jason Momoa as the titular hero, reprising his role from Batman v Superman: Dawn of Justice and Justice League, along with Amber Heard as Mera, Patrick Wilson as Ocean Master, Willem Dafoe as Dr. Vulko, Yahya Abdul-Mateen II as Black Manta, Dolph Lundgren as King Nereus, Nicole Kidman as Atlanna, Temuera Morrison as Tom Curry, Ludi Lin as Murk and Otis Dhanji as a young Arthur Curry. It is set for release on December 21st 2018.
