Aquaman adds Dolph Lundgren in a villainous role as Warner Bros. continues inching closer to the start of their next DCEU project. James Wan is currently finishing the pre-production stage on his DC debut that will mark the third appearance of Jason Momoa as the titular character. Momoa has already made his way to Australia to gear up for filming, while Amber Heard (Mera) has continued to keep up to date on her training.
With filming not yet underway, much of the plot remains unknown, outside of the inclusion of Black Manta, indicating he and Arthur Curry clash will over control of the sea. Well, it looks like Black Manta will not be the only foe Aquaman will have to fight off in his first solo film.
THR is reporting that Dolph Lundgren is hopping back into the superhero genre for a role in Aquaman as King Nereus. He is the ruler of Xebel, the home city of Mera. For the purposes of the movie THR says Nereus “claims Mera as his own and wants to kill Aquaman,” putting Lundgren definitively in an antagonistic role.
Here's a shot of the comic book likeness of Dolph's character:

Pretty cool news.
