It seems Warner Bros. are excited enough by Guillermo del Toro's script for Dark Universe, that they're interested in moving forward despite the Crimson Peak director leaving the project. Though they don't have a new director in place just yet, Latino Review has heard about several of the cast members they'd like to fill the various roles of DC's motley crew of witches, wizards, demons and dead men.
Apparently Del Toro wanted Ron Perlman for Swamp Thing and the studio like that idea, but they're also keen on Colin Farrell for John Constantine, and Monica Bellucci for Madame Xanadu. Word is Ewan McGregor has also been approached for the Constantine role, but he may "fall back on" Jason Blood, AKA Etrigan the Demon. The site also adds that they're seeking a "comedic presence" for Deadman, and an Hispanic/black actress to fill the role of Zatanna.
All with the usual grain of salt for now of course, but these are some very intriguing choices so let's hope there's some truth to it, and that the actors show interest.
