Days after it was cancelled after its first episode, it was reported that Swamp Thing had a three season plan to introduce Justice League Dark. DC hasn’t made an official announcement as to why the series was cancelled, much to the surprise of the cast and crew, which makes the Justice League Dark reveal even more surprising.
Justice League Dark is the magic-based iteration of the Justice League, whose members include Etrigan The Demon, Madame Xanadu, Deadman, Shade, the Changing Man, and Zatanna. The report claims that Swamp Thing would’ve been used as a way to spin off these characters into their own series.
In 2013, it was revealed that Guillermo del Toro was working on a Justice League Dark film. 2015 saw del Toro leave the film and Doug Liman stepping in direct. A year later, Liman left the project and it’s been in development hell ever since.
