As Jason Momoa's Aquaman and the Lost Kingdom is slated to hit the theatres on December 20, the director of the film James Wan recently revealed that one of the key themes for the next installment in the franchise will be touching upon global warning.

"I think people are going to be excited to see that this movie is quite different from the first movie in terms of tone. It’s a little bit more serious, and we’re dealing with issues like climate change. We’re not afraid to lean into that in a big way, because the Aquaman comic book, even way back when, has always been environmentally conscious. He’s always been someone who’s fought to keep the ocean clean, and it feels more relevant in the world that we’re living in today. So this movie has something to talk about, but it’s still a fun action-fantasy movie," the director was quoted as saying by a Collider report.

Aquaman and the Lost Kingdom will see Jason Momoa returning in his titular role and also marks the return of Amber Heard, Patrick Wilson, Dolph Lundgren, and Yahya Abdul-Mateen II. The filming of the sequel commenced earlier last June. James Wan will direct from a script provided by David Leslie Johnson-McGoldrick.
