Aquaman spinoff, The Trench, in the works
Noah Gardner and Aidan Fitzgerald will write the script centred on the Trench, the deadly amphibious creatures who attacked Aquaman (Jason Momoa) and Mera (Amber Heard) in the movie. The project will be set in the undersea kingdom in the Marianas Trench, where a group of the original inhabitants who were sent after Atlantis sunk and evolved into savage monsters.
James Wan and Peter Safran will produce The Trench, which is being developed as a lower-cost version of Aquaman without the main cast. The movie does not have a cast or crew yet.
The Trench creatures were created by Geoff Johns and introduced as antagonists in the Aquaman storyline in DC Comics in 2011. The Mariana Trench is the deepest point on the planet and has served as the home of antagonists in The Meg and Pacific Rim.
