Guillermo Del Toro
Rumors in November 2012 suggested that Guillermo del Toro was working on a Justice League Dark film titled Heaven Sent. It would feature Deadman, the Spectre, Swamp Thing, John Constantine, Phantom Stranger, Zatanna, Zatara, Sargon the Sorcerer, and Etrigan the Demon. Del Toro later confirmed in January 2013 that he is working on such a film, with the working title, Dark Universe, and was hiring a screenwriter. Del Toro revealed Swamp Thing, Constantine, The Spectre, Deadman, Zatanna and Zatara were characters in the story.
In March 2013, del Toro gave an update on the film at WonderCon 2013, while talking about his film Pacific Rim. He revealed that the story bible was complete and he hoped to start the screenplay soon. Production would begin after his next project, Crimson Peak. The film's story would center around John Constantine recruiting Swamp Thing, Etrigan the Demon, Deadman, Spectre, and Zatanna. The film would not be an origin story, with each character already established and elements of their backstory coming into play throughout the film. Del Toro also revealed that Floronic Man will be in the film. In May 2013, del Toro revealed that his script features Constantine, Swamp Thing, Madame Xanadu, Deadman and Zatanna as the team, with other "in the mix". He also revealed that he was still waiting for the go-ahead from Warner Bros. Pictures. Del Toro revealed in July 2013 that he hopes the DC Extended Universe, which started with Man of Steel, will become as cohesive as the Marvel Cinematic Universe, and he added that if there was any correlation to that universe and this film, he would honor it.
In October 2013, del Toro stated he felt his film would be able to coexist with the television series, Constantine and reiterated that the film was still active and in the writing process. In July 2014, del Toro once again stated he was working on the film, and stated it would be independent from the universe established with Man of Steel, saying, "DC and Warners have been very clear that they are trying to keep [this film and Sandman] separate so when the time comes they can unite them, once they know they’re quantifiable." Del Toro also added that his Constantine would not adhere to the continuity established in the television series, but he would consider incorporating elements from it, and even think about casting the same actor (Matt Ryan). In November 2014, del Toro confirmed that the script was complete and handed it in to Warner Bros. to be reviewed. In December 2014, he hinted that the film will be part of the DC Extended Universe.
In April 2015, del Toro said the script revision has been handed in and if there was availability in his schedule, he would direct it; if not, "somebody else will do it... [The film] needs to fall into the plan of the shared universe." In June 2015, the film was confirmed to still be in development at Warner Bros., with some of their other Vertigo Comics film adaptions moving to New Line Cinema. The Hollywood Reporter stated that del Toro was no longer attached to the project. In August 2016, it was announced that Doug Liman will direct the film with del Toro and Scott Rudin producing and Michael Gilio writing with the film being titled Dark Universe.
