NBC has given the green light for a TV series based on DC Comic's John Constantine. Constantine will follow the dark sorcerer and detective as he is forced to protect the world from evil. The antihero first came out as bisexual in an early 90's issue of the long-running John Constantine: Hellblazer.
The Constantine pilot is being headed up by executive producers Daniel Cerone and David S. Goyer, the latter of which was a script writer for Christopher Nolan's Batman trilogy and Man of Steel.
Looks promising--especially with a Batman trilogy alum like Goyer attached--but I hope they don't shy away or water down Constantine's sexuality.
