Warner Bros. has taken the first step towards the production of Aquaman 2, by bringing back David Leslie Johnson-McGoldrick to write the script. Johnson-McGoldrick had begun working on the Aquaman screenplay when he read the comics, three years ago. Aquaman, starring Jason Momoa and Amber Heard, had brought in $68.7 million within its opening weekend in North America. The title gained momentum in the following weeks, and hit $330 million in North America and $805 million internationally. The movie is currently the 20th-highest worldwide grosser of all time. Warner Bros. also announced that it was developing The Trench, a horror movie spinoff to Aquaman.
