Aquaman and the Lost Kingdom features a star-studded cast led by DC star Jason Momoa.
Directed by James Wan, Aquaman 2 is poised to be the send-off for the current DCEU, bringing together Momoa's titular hero and the Kingdom of Atlantis for one final adventure.
Marketing has yet to ramp up for the DC sequel, but anticipation is mixed after The Flash's recent box office failure.
Aquaman 2 Cast: Every Actor & Character
Jason Momoa - Arthur Curry/Aquaman
Jason Momoa returns as Arthur Curry (aka Aquaman) for, presumably, one last time in the upcoming DC sequel.
At the end of the first film, Arthur becomes king of Atlantis and protector of the seas, and this responsibility is pushed to the forefront in Aquaman 2.
Alongside his leadership duties, Arthur also tries to keep his new family together due to the birth of his son, Arthur Jr.
Conversations surrounding Momoa's time as Aquaman have made headlines amid the impending DC reboot. It is unknown if the actor's iteration will carry over into the new DCU, but Momoa already casted doubt on a potential third movie.
Amber Heard - Mera
Despite the controversies she faced with her husband Johnny Depp and fan backlash, Amber Heard returns as Mera in Aquaman 2.
In August 2022, The Wrap reported that Heard will only have "20 minutes" of screen time in the sequel, indicating that she has a minor role.
During the actress' legal battle, it was revealed that Mera is pregnant in the movie.
In Aquaman and the Lost Kingdom, though, Mera has a significant role, becoming Queen of Atlantis, a parent, and one of Atlantis' greatest warriors.
Patrick Wilson - Orm Marius
After serving as the main villain in the first movie, Patrick Wilson's Orm Marius returns in Aquaman 2.
Aside from sporting a new look, Orm (reluctantly) teams up with Momoa's Aquaman to try and defeat Black Manta, who is possessed by King Necrus.
Wilson is best known for his roles in the Insidious and Conjuring horror franchises.
Dolph Lundgren - King Nereus
Dolph Lundgren makes his DCEU comeback as King Nereus, Mera's father and the leader of Xebel.
Lundgren said that the sequel is "better" than its predecessor, teasing that the "script is stronger and it's more exciting."
In Aquaman 2, King Nereus has a more active role in the quest to find Black Manta, tagging along the forces of Atlantis to put an end to his terrifying reign.
Lundgren is known for Rocky IV, Masters of the Universe, and The Expendables.
Yahya Abdul-Mateen II - David Kane / Black Manta
Yahya Abdul-Mateen II reprises his DCEU role as David Kane aka Black Manta.
Aquaman's post-credits scene managed to set up Black Manta's bigger role in the sequel, meaning that he has a bone to pick with Jason Momoa's titular hero.
Alongside Atlantean upgrades and his new partnership with Stephen Shin, Black Manta is much more dangerous in Aquaman 2.
Black Manta also has a new weapon called the Black Trident, an ancient artifact held by King Necrus of the Lost Kingdom.
Abdul-Mateen II is set to star as Simon Williams in Marvel Studios' Wonder Man series. The actor is also known for his roles in Candyman, Black Mirror, and HBO"s Watchmen series.
Randall Park - Dr. Stephen Shin
Randall Park returns as Dr. Stephen Shin in Aquaman 2.
During the first film, the character was pretty obsessed with proving that Atlantis exists, and it seems that this obsession will carry over in the sequel as he teams up with Black Manta to try to take down the titular hero.
Park is known for his role as the MCU's Jimmy Woo. The actor's other credits include The Interview, Always Be My Maybe, and Fresh of the Boat.
Temuera Morrison - Thomas Curry
After briefly returning in The Flash, Temuera Morrison also reprises his role as Thomas Curry, Arthur's human father, in Aquaman 2.
Morrison is best known for his role as Boba Fett and Jango Fett in the Star Wars movies.
Nicole Kidman - Atlanna
Nicole Kidman is also back as Atlanna in the DC sequel, the former queen of Atlantis and Arthur and Orm's birth mother.
Atlanna plays an active role in protecting her family from the forces of Black Manta. After Arthur and Orm reunite, Atlanna tells both of them to do their best to set aside their differences and protect one another.
Kidman's past credits include Rabbit Hole, The Golden Compass, The Invasion, and Batman Forever.
Indya Moore - Karshon
Indya Moore is one of the newcomers who joins the DC universe in Aquaman 2.
In September 2021, it was reported that Moore had joined the cast of the sequel as Karshon, a Green Lantern villain from the comics.
In DC Comics, Karshon (aka The Shark) is a telepathic and anthropomorphic tiger shark whose evolution was fast-tracked after being hit by radiation.
Moore's version of Karshon in Aquaman 2 is drastically different. Karshon is a member of the High Council, and Arthur is clearly not a fan of her inclusion.
Moore is known for her roles in Pose and Escape Room.
Pilou Asbæk - Kordax, King of Necrus
Pilou Asbæk plays King Kordax of Necrus, one of the chief villains in Aquaman and the Lost Kingdom. Kordax is also King Atlan's brother whom he defeated in a previous war between Necrus and Atlantis.
In an interview with Comicbookmovie in August 2022, Asbæk briefly teased his involvement in the sequel, saying, "Yes! That’s gonna be cool...but I can’t say anything!"
Aside from Game of Thrones, Asbæk is known for Samaritan, Ghost in the Shell, and Overlord.
Jani Zhao - Stingray
Jani Zhao portrays Stingray in Aquaman 2, an original character created for the sequel. Stingray serves as one of Black Manta's loyal enforcers in the sequel.
Zhao's past credits include The Sugar Captains, South, and California.
Vincent Regan - King Atlan
Vincent Regan is back as King Atlan in the DCEU sequel.
The character served as the original king of Atlantis prior to its submergence and the owner of the powerful trident.
Aquaman 2 relives the crumbling relationship between King Atlan and his brother, Kordax, ultimately leading to the fall of Necrus.
Regan is known for his roles in 300, Lockout, Troy, and Clash of the Titans.
Martin Short - Kingfish
Veteran comedian Martin Short joins the cast of Aquaman 2 as the voice of Kingfish, the leader of the pirates who is situated in the Sunken Citadel.
Kingfish is integral to Aquaman 2's story since he is the one who gave Black Manta's location to Arthur and Orm.
Short recently appeared as Oliver Putnam in Only Murders in the Building. The actor also has credits in Inherent Vice, Innerspace, and How I Met Your Mother.
John Rhys-Davies - Brine King
John Rhys-Davies lends his voice to Brine King, the leader of the Brine Kingdom who joins Arthur, Orm, Mera, and King Nereus to fend off the forces of Black Manta and Necrus.
Rhys-Davies also serves as the voice of other characters in the DC Animated Universe, such as Baron Waclaw Jozek in Batman: The Animated Series and Hades in Justice League.
Aquaman and the Lost Kingdom is set to premiere in theaters on December 25.
