With the likes of Gotham (FOX), Agent Carter (ABC) and The Flash (the CW), it seems that NBC themselves also want to get into the comic book and have commissioned Constantine for a series.
The official description from NBC ...
Based on DC Comics' Hellblazer graphic novels, the drama centers on master of the occult John Constantine (Matt Ryan - Torchwood).
The drama centers on Constantine as he struggles with his faith while
haunted by the sins of his past but is suddenly thrust into the role of
defending humanity from the gathering forces of darkness. Dexter's Daniel Cerone penned the script and will exec produce the Warner Bros. Television drama alongside David S. Goyer (The Dark Knight trilogy, Man Of Steel, DaVinci's Demons). Lucy Griffiths (Robin Hood, True Blood), Harold Perrineau (Oz, Lost)and Charles Halford co-star.
I have to admit this really could go either way as a series. Constantine as a show seems more like something that would be better suited to a cable channel for adaptation rather than a network but NBC have done well with the likes of adapting Hannibal, so perhaps it will work out well here and it'll probably be better than the Keanu Reeves movie did a few years ago and at least Matt Ryan looks the part too. Either way, this fall season certainly seems to have an interesting influx of comic adaptations, doesn't it?
