Beall, who wrote an early draft of the upcoming "Justice League" film, was hired in 2014 alongside frequent Zack Snyder collaborator Kurt Johnstad to work on separate "Aquaman" scripts to be developed on a "dual track." THR notes that "The Conjuring 2" writer David Leslie Johnson was added to the mix last year when Wan joined the project.
The website reports the dual-track approach was recently abandoned as Wan and Johns began to focus on the script. Beall then rejoined the project.
Opening July 27, 2018, "Aquaman" stars Jason Momoa as DC Comics' Sea King, Amber Heard as Mera, and Willem Defoe as Vulko.
