In a new interview, filmmaker Guillermo del Toro updated Total Film on the progress of his forthcoming Justice League Dark movie, Dark Universe. Among other things, he gave the first semi-official insight into what characters might be involved, with previous reports that the movie would star Swamp Thing, Constantine, Madame Xanadu and others rooted in rumor and speculation. "I am going to be presenting my storyline to DC and Warners of where I want to take this universe," del Toro said. "We do have a writer, but until that is firmed up, I have to keep it a secret. I hope it happens." He added, "It's going really, really well. It's like meeting old friends. I grew up with Demon Etrigan, with Swamp Thing, with Deadman, so these are characters that are near and dear to my heart." Given that most casual audience members wouldn't know most of the characters, it's probably unsurprising that del Toro would want to do a spin on some of their origins and mythology for the film. "I'd love to use the origins that are proper to each character," he said. "I love the idea of Jason Blood as a paladin and a knight...I love the entire Constantine mythology, the Deadman mythology, the Alec Holland Swamp Thing mythology. These are really rich things to well, and to dig."
