"After 115-days of photography, that’s a wrap on @patrickwilson73," the filmmaker announced this morning. "Thank you for accompanying us on this aquatic adventure."

Wan and Wilson are frequent collaborators, having previously worked together on Insidious and The Conjuring, and their sequels.

Introduced in 1966's Aquaman #29, Ocean Master is Prince Orm, the villainous half-brother of DC Comics' Sea King.

While details remain scarce on Aquaman's plot, Wan has promised a “swashbuckling action-adventure, sort of high seas adventure story” with Jason Momoa in the title role. He said it will be in the vein of 1980s classics like Raiders of the Lost Ark and Romancing the Stone, teasing that it's “ultimately a quest story,” without revealing what the object of that search is.

Arriving Dec. 21, 2018, Aquaman stars Jason Momoa as Aquaman/Arthur Curry, Willem Dafoe as Nuidis Vulko, Amber Heard as Mera, Patrick Wilson as Ocean Master, Yahya Abdul-Mateen II as Black Manta, Temuera Morrison as Thomas Curry, Dolph Lundgren as Nereus, Nicole Kidman as Atlanna, Ludi Lin as Murk, and Michael Beach as Jesse Kane.
