“The Trench” is getting developed as a spin-off of horror movie “Aquaman”, which released last year.

Warner Bros studio has hired Noah Gardner and Aidan Fitzgerald to write a script centred on the Trench, the deadly amphibious creatures that attacked Aquaman (actor Jason Momoa) and Mera (actress Amber Heard) in the movie, reports variety.com.

The project will be set in the undersea kingdom in the Marianas Trench, where a group of the original inhabitants 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 involved. No director or cast is yet attached.

The Trench creatures were created by Geoff Johns and introduced as antagonists in the Aquaman storyline in DC Comics in 2011.
