Justice League: 8 Big Changes It Will Bring To The DCEU

Justice League is set to make the DC Extended Universe a larger and more diverse place, complete with its very own underwater kingdom.

Naturally, we're talking about the deep sea realm of Atlantis, a place that must feature heavily in the film since it has an Aquaman solo outing to set up.

We already know Jason Momoa's Atlantean king will have a big role in the movie, but its cast list confirms that we'll also get a close look at Amber Heard's Mera and Willem Dafoe's Machiavellian Nuidis Vulko in action.

Wonder Woman has already showed us some of the DC Universe's mythical depths by unveiling Themyscira, but it will feel like a much bigger location once Atlantis has been added it its map and the Aquaman groundwork has been laid.
