With more than $1.121 billion, Aquaman is at present the highest grossing DC Comics movie (globally) ever, even above The Dark Knight, etc. That’s a significant accomplishment for a character long considered a joke (including a long-running story arc on HBO’s Entourage).
All hints advocate that Warner Bros. is taking its nod from the successes of both Aquaman and Wonder Woman to tilt the tone of future films away from the “grimdark” of Christopher Nolan and Zack Snyder’s movies.
Those numbers also made it super obvious that Aquaman would get a sequel, and that’s precisely what’s happening, with one of the first film’s screenwriters currently working on a follow-up.
Aquaman director James Wan is on board as producer, but it’s vague as to whether he will also direct the sequel. Warner Bros. isn’t stopping there, though, as they’ve also hired two “newbie” screenwriters to work on a horror movie spinoff called The Trench, about the ”deadly amphibious creatures seen attacking the hero and his love, Mera” in Aquaman.
The main characters from Aquaman are not expected to appear in The Trench, which hints that the “horror movie” may instead focus on surface dwellers who come into contact with the monsters separate from any connection with Atlantis.
It’s also possible that Aquaman 2 and The Trench could just be the start of a new franchise of Aquaman related movies in the same way that Batman has led to films for Suicide Squad, Joker, Birds of Prey, etc.
