During Saturday's panel for Pacific Rim at WonderCon, director Guillermo del Toro said that John Constantine -- a blond one, he emphasized -- will be the main protagonist in his planned Justice League Dark movie tentatively titled Dark Universe

Constantine will be the central figure who rounds up the gang. The director revealed that the film won't be an origin movie per se, with each character already established but elements of their backstory coming into play during the course of the story. For example, Swamp Thing is now at peace with who he is, but Deadman will still be in search of the man who murdered him.In addition to Constantine, Deadman and Swamp Thing, del Toro said the team's members will include Etrigan the Demon and Jason Blood, whose past with Merlin's Knights will be mentioned. (Zatanna and the Spectre have also been previously mentioned as members.)Del Toro said they have finished the bible for the movie and hope to start the screenplay soon with a writer whose identity he still can't reveal. Dark Universe will not be del Toro's next film, though, as the helmer said he expects to shoot Crimson Peak after Pacific Rim is done.
