The Aquaman sequel is to be the last of the DCEU.

Director James Wan is set to reunite with Jason Momoa for “Aquaman and the Lost Kingdom.” It is the most anticipated sequel to the highest-grossing DC film ever. It will be in theaters on December 20. Joining them are familiar faces from the first installment. Patrick Wilson, Amber Heard, Yahya Abdul-Mateen II, and Nicole Kidman are returning. In the sequel, Momoa returns as Arthur Curry, who now faces the daunting task of balancing his duties as the King of Atlantis with his newfound role as a father.
The stakes are higher than ever as Black Manta (Abdul-Mateen II) returns with a burning desire to avenge his father’s death and wield the mythical Black Trident, which harbors an evil force. Aquaman must forge an unlikely alliance with his imprisoned brother Orm, played by Patrick Wilson, the former King of Atlantis, to combat this new threat. Together, they must set aside their differences to safeguard their kingdom, protect Aquaman’s family, and prevent irreversible destruction from befalling the world.
