Set to star the more supernatural characters of the DC Comics, Justice League Dark will feature characters such as Constantine, Deadman, Swamp Thing and the Demon.
While promoting Pacific Rim, Guillermo Del Toro offers an updated on the Justice League Dark movie, and the good news is that it's in very active development as they are just waiting for the writer (which some think to be Man of Steel writer David Goyer).
Here is the update (via The Collider):
Justice League Dark is very active. I’m doing one more revision while we wait for the writer. It’s somebody big, [and] we’re patiently waiting for that writer. I think it’s worth it, I think it’s a guy we all admire. I’m doing my revisions on my sort of Bible, on my story for the film. I can tell you it’s the writing project I’ve enjoyed the most in English. Devil’s Backbone and Pan’s Labyrinth are in Spanish, but of all my writing and screenplays, this was so much fun because it was character. It was a pretty easy plot, but the character interaction, Swamp Thing with Deadman and Demon, it’s so joyful for me to write that. Constantine is such a great character, so dry. I think it could be a great movie. I don’t want to do many changes until the proper writer comes onboard.
