The revelations about Aquaman and the Lost Kingdom's reshoot chaos may support the idea of Jason Momoa being recast in the upcoming DCU. Since 2016, Jason Momoa has portrayed Arthur Curry/Aquaman in the DCEU, appearing in Batman v Superman: Dawn of Justice, Justice League, Aquaman, Zack Snyder's Justice League, and The Flash. The second leading-role appearance of Momoa is expected to be released in December 2023: Aquaman and the Lost Kingdom.
