Here is the official synopsis and information from Warner Brothers:
From Warner Bros. Pictures and director James Wan comes an action-packed adventure that spans the vast, visually breathtaking underwater world of the seven seas, Aquaman, starring Jason Momoa in the title role. The film reveals the origin story of half-human, half-Atlantean Arthur Curry and takes him on the journey of his lifetime — one that will not only force him to face who he really is, but to discover if he is worthy of who he was born to be … a king.
The film also stars Amber Heard (Justice League, Magic Mike XXL) as Mera, a fierce warrior and Aquaman’s ally throughout his journey; Oscar nominee Willem Dafoe (Platoon, Spider-Man 2) as Vulko, council to the Atlantean throne; Patrick Wilson (The Conjuring films, Watchmen) as Orm/Ocean Master, the present King of Atlantis; Dolph Lundgren (The Expendables films) as Nereus, King of the Atlantean tribe Xebel; Yahya Abdul-Mateen II (Baywatch, Netflix’s The Get Down) as the vengeful Black Manta; and Oscar winner Nicole Kidman (The Hours, Lion) as Arthrur’s mom, Atlanna; as well as Ludi Lin (Power Rangers) as Captain Murk, Atlantean Commando; and Temuera Morrison (Star Wars: Episode II – Attack of the Clones, Green Lantern) as Arthur’s dad, Tom Curry.
Wan directs from a screenplay by David Leslie Johnson-McGoldrick (The Conjuring 2) and Will Beall (Gangstar Squad, TV’s Training Day), story by Geoff Johns & James Wan and Will Beal, based on characters from DC, Aquaman created by Paul Norris and Mort Weisinger. the film is produced by Peter Safran and Rob Cowan, with Deborah Snyder, Zack Snyder, Jon Berg, Geoff Johns and Walter Hamada serving as executive producers.
