In this epic new chapter directed by James Wan, Jason Momoa returns as Arthur Curry, the reluctant king of Atlantis who finds his land and family threatened by an ancient power unleashed from the depths. To face a foe with the devastating potential to destroy both the surface world and the undersea kingdoms, the once-estranged Aquaman must forge an uneasy alliance with his imprisoned brother, Orm, played by Patrick Wilson. As they embark on a perilous quest to find the mythic Lost Kingdom, Arthur is also tested on the homefront, balancing his royal duties with his life alongside his queen, Mera (Amber Heard), and his father, Tom (Temuera Morrison). This high-stakes adventure plunges audiences into a visually stunning world of fantastical action and deep-sea intrigue, where old enemies must become new allies to prevent an unimaginable catastrophe.
