Aquaman…time to meet your nemesis!

Insidious‘ Patrick Wilson has scored the role of the villain in James Wan‘s upcoming adaptation of the DC Comics superhero with Jason Momoa reprising his role from his cameo in Batman v. Superman and the upcoming Justice League movie.

Wilson is a favorite of Wan’s, having appeared not only in Insidious but Wan’s recent outing The Conjuring. Wilson will play Orm Marius, the evil half-brother of our hero who becomes known as Ocean Master (right). Wilson joins Momoa, Amber Heard, and Willem Dafoe in the film, which is due for release on October 5, 2018 from Warner Bros. and DC.
