One of the great what-ifs of Hollywood comic book films is undoubtedly the Guillermo Del Toro Justice League Dark that never was. While the movie is apparently still in the works from Warner Bros., Del Toro left the project a few years after its announcement due to a combination of scheduling conflicts and the sudden rise of the DC Extended Universe. Recently, however, the auteur explained a bit more what his original plan was for the supernatural anti-heroes.
“Suffice to say that Demon or Swamp Thing mean to me what Batman and Superman mean to most mortals - perhaps even more. Swamp/Abigail love was a great source of inspiration for me,” he said during a Reddit AMA, referring to the relationship between Swamp Thing and Abigail Holland, as well as the rhyme-happy hellspawn, Etrigan.
Alec and Abigail Holland's long-term relationship is one of the hallmarks of DC Comics' Swamp Thing mythos, resulting in some of fans' most beloved stories over the years. Given Del Toro's penchant for tales about otherworldly love and forlorn demons, his plan to anchor the film around the two characters alongside Etrigan probably isn't too surprising to most.
While the script is currently being polished by Gerard Johnstone (Housebound), Justice League Dark still lacks casting and a release window.
