Constantine: Lauren Shuler Donner, producer of the upcoming comic book adaptation Constantine, starring Keanu Reeves, recently spoke with Sci-Fi Wire about the project.

"It's not an origin story of the character," played by Keanu Reeves, Donner said in an interview while promoting her next movie, Timeline. "It's 'Dangerous Habits,' if you know the Hellblazer [series]." RELATED: Why The Sandman Had to Recast Constantine for Netflix and What That Means Moving Forward

"Dangerous Habits," the 1994 graphic novel by Irish writer Garth Ennis, focuses on John Constantine, a magician faced with death from lung cancer, who finds himself straddling the line between life and death, heaven and hell. "We're filming," Donner said. "We're about a third into it. It's come along great. And it'll be out next year, probably, well, at the moment, September."

Donner added, "We're shooting in L.A. A lot at Warner Brothers. A lot downtown. Two weeks we're in Long Beach. And we're trying to stay as true to the comic as we can, though it's an obscure comic. Not many people know Hellblazer. And it's coming along well. We have a new director named Francis Lawrence, who's just doing a great job. We're very lucky, because he understands actors and understands the importance of telling a story, and not just the visuals. And yet it's going to be very stylish."
