It's learned Guillermo del Toro is no longer attached to Justice League Dark.
Yesterday saw Warner Bros. shuffle their DC Vertigo titles around which saw Sandman moved from WB to sister arm, New Line Cinema.
In THR's report on the news, they state insiders say Guillermo del Toro is working on Pacific Rim 2 and is prepping for the release of Crimson Peak and is no longer set to direct Justice League Dark.
It is noted Justice League Dark is still at Warner Bros.; the movie is set feature the supernatural characters of the DCU including Constantine, Swamp Thing, Zatanna, and Deadman. The reason given (which may be why Guillermo del Toro is no longer attached) is that DC Comics recently moved the JLD characters into their regular DC Universe and the movie is doing the same.
Sandman is based on the Neil Gaiman comic and is being developed by Jospeh Gordon Levitt.
Dwayne Johnson's Shazam is still at New Line as well.
Deadline reports the reason for the Vertigo titles shifting to New Line under Toby Emmerich and Richard Brener is that the Vertigo titles are considered "subversive" compared to the WB-steered DC Comics titles with those "venerable superheroes."
