According to The Hollywood Reporter, Noah Gardner and Aidan Fitzgerald have been hired to pen a horror-inspired about the Trench, a sect of Atlantians who evolved into feral creatures that dwell in darkness. Aquaman director James Wan and Peter Safran are attached as producers. This spinoff would likely hit theaters before a direct sequel, which is in talks but not yet in the works at the studio.
Appropriately, The Trench spinoff will be set in the Kingdom of the Trench. However, the main cast of Aquaman will not appear. Additional details are being kept under wraps.
In the comics, the Trench debuted in 2011's Aquaman #1 by Geoff Johns and Ivan Reis. When Atlantis fell into the ocean, the people of the Trench settled in a trench near the Mid-Atlantic Ridge, developing their own language and adapting to the conditions of their new home. As depicted in the film, they appear more animalistic, in that they do not speak and attack anything that enters their territory.
Directed by James Wan, Aquaman stars Jason Momoa as Aquaman, Amber Heard as Mera, Patrick Wilson as Orm, Willem Dafoe as Nuidis Vulko, Yahya Abdul-Mateen II as Black Manta, Temuera Morrison as Thomas Curry, Dolph Lundgren as Nereus and Nicole Kidman as Queen Atlanna. The film is now in theaters nationwide.
