Jason Momoa will play the titular character in the film while no actor has signed on to play the villain (nor has Warner Bros. confirmed Black Manta will be in the film).
According to The Wrap, Black Manta – Aquaman’s long-term arch-nemesis – will feature, coming as no surprise to DC fans.
Before then, Momoa will reprise his role as Aquaman in Justice League, having previously appeared as the character in Batman v Superman.
Recently, director James Wan discussed bringing in horror elements, while a new report has seemingly revealed the film’s villain.
