With “Aquaman” raking in over a billion dollars at the box-office, Warner Bros. Pictures isn’t wasting time and has already begun developing not just a sequel but a spin-off revolving around The Trench creatures.

What the spin-off involves however is not clear. There have been some reports saying it won’t include any characters from “Aquaman” while others suggest Jason Momoa and Amber Heard will be making an appearance.

Whatever the case, “Aquaman” director James Wan (who is only producing “The Trench” spin-off) offered an idea of the tone to expect from the new film which is definitely not a superhero movie. He tells ComicBook.com:

“We, you know, we’re still deep in sort of crafting the script, crafting the story right now so I don’t want to get into that too much, but definitely it’s one that I really want to lean into the horror of it, so it’s going to play more as a monster horror movie then it will as a superhero film, but it’s still definitely part of the Aquaman world.”

The Kingdom of the Trench is one of the seven kingdoms that splintered off when ancient Atlantis sank, and its inhabitants devolved into savage deep-sea beings. Within said kingdom is a one-way portal to the Hidden Sea at the Earth’s core.

It’s expected “The Trench” film will arrive before the “Aquaman” sequel hits cinemas, the latter is currently targeting a December 2022 release.
