WARNING: This article contains potential spoilers for director James Wan's "Aquaman."


Warner Bros. announced in December that "Watchmen" actor Patrick Wilson will play Aquaman's brother Orm, better known as the DC Comics villain Ocean Master, in the upcoming "Aquaman" film. However, a new Instagram post from star Jason Momoa seems to suggest Orm might not merely be the master of the ocean but also the ruler of Atlantis.

The photo shows Momoa and Wilson standing side by side, posing with contrasting expressions of silliness and sternness, but it's the accompanying caption that raises an eyebrow. In it, Momoa refers to himself as Arthur, and Wilson as "King" Orm.

Does this mean Ocean Master will sit on the throne of Atlantis when "Aquaman" hits theaters? Well, there's certainly precedent for that in the comic book source material. In DC Comics' New 52, when Orm's father is killed and Queen Atlanna dies unexpectedly, it's Orm who inherits the crown. After receiving assistance from the Justice League, Aquaman is able to defeat his brother and reclaim his kingdom.

Details surrounding the plot of "Aquaman" are scarce, so whether we see a similar storyline play out remains to be seen. However, this does seem to conflict with earlier reports, which stated the film will center on Aquaman as a reluctant ruler who's caught between land dwellers that are always polluting the globe and his own people who are ready to invade the surface.

The film arrives in theaters Dec. 21, 2018, but Momoa will next be seen as Aquman in director Zack Snyder's "Justice League," which opens Nov. 17.
