This is my fan casting for a possible Justice League Dark movie, there are more characters that they had included in the current comics like Andrew Bennett, Black Orchid, Mindwarp and Doctor Mist, plus some characters mentioned by Guillermo del Toro like Etrigan the Demon and Sargon the Socerer, but I decided to keep these 13 characters.
Paul Betanny as John Constantine
Olivia Wilde as Zatanna
Sam Rockwell as Deadman
Paz Vega como Madame Xadanu
Taylor Kisch as Shade
Daniel Radcliffe as Tim Hunter
Note: When I was reading about this guy Harry Potter keep popping in my head. This is not going to happen, but I think it's funny.
Kevin Bacon as The Swamp Thing
Villains
Keanu Reeves as Nick Necro
Note: When I read Justice League 0, I couldn't help to remember Keanu's Constantine. This is not going to happen either.
Jessica Chastain as Enchantress
Jackie Earle Haley as Felix Faust
Supporting Cast
Alessandro Nivola as John Zatara
Paul Walker as Steve Trevor
Kerry Washington as Amanda Waller
