Warner Bros. is reportedly starting afresh on Justice League Dark and Doctor Strange writer Jon Spaihts is reportedly leading the charge.
Justice League Dark is currently in development and has no official release date.
Some of the difficulties with Justice League Dark could be the outcome of the DCEU and its unfixed future.
Justice League Dark has yet to get off the ground, however, despite both Guillermo Del Toro and Doug Liman having been involved in its development before stepping down.
