Gunn confirmed that the previously announced Wonder Woman- adjacent project, Paradise Lost, a prequel series set on the island of Thymascira, Wonder Woman's home, but set long before her, was still in development. Gunn called the series "slow moving" but assured that it is still moving forward.

In an interview with Entertainment Weekly, the “Superman” director revealed that a new “Wonder Woman” film is “being written right now,” alongside an already-announced HBO series “Paradise Island,” which will focus on the superhero’s homeland of Themyscira and which Gunn says development is “slow moving, but it’s moving.”
