NBC's 'Constantine' seemingly rededicated itself to exploring its DC roots with the most recent casting, and at long last, the TV adaptation of our 'Hellblazer' demon detective has its big bad. Michael James Shaw has been cast in the 'Constantine' role of the villainous Papa Midnite, a "formidable magical adversary" for our leading man.

News of Shaw's casting comes from USA Today, who add that the recurring guest role will emerge as the voodoo king of New Orleans, though the demonic forces rising all over may necessitate the two enemies working together before long. For his part, Michael James Shaw has few recognizable credits beyond a brief (and apparently uncredited) appearance in 'The Wire,' while Papa Midnite has appeared in 'Hellblazer' comics dating back to 1988.

Papa Midnite is known as an immortal voodoo priest and organized crime leader, and foe to John Constantine in the comics, while worth noting is that 'Guardians of the Galaxy' star Djimon Hounsou played an incarnation of the villain in the 2005 Keanu Reeves 'Constantine' adaptation.

Apart from the addition of telenovela star Angelica Celaya as comic character Zed, here’s how NBC describes its ‘Constantine' TV series:

Based on the wildly popular comic book series “Hellblazer” from DC Comics, seasoned demon hunter and master of the occult John Constantine (Matt Ryan, “Criminal Minds”) specializes in giving hell… hell. Armed with a ferocious knowledge of the dark arts and his wickedly naughty wit, he fights the good fight — or at least he did. With his soul already damned to hell, he’s decided to leave his do-gooder life behind, but when demons target Liv (Lucy Griffiths, “True Blood”), the daughter of one of Constantine’s oldest friends, he’s reluctantly thrust back into the fray – and he’ll do whatever it takes to save her.

Before long, it’s revealed that Liv’s “second sight” — an ability to see the worlds behind our world and predict supernatural occurrences — is a threat to a mysterious new evil that’s rising in the shadows. Now it’s not just Liv who needs protection; the angels are starting to get worried too. So, together, Constantine and Liv must use her power and his skills to travel the country, find the demons that threaten our world and send them back where they belong. After that, who knows… maybe there’s hope for him and his soul after all.

The cast also includes Harold Perrineau and Charles Halford. Writer Daniel Cerone (“The Mentalist,” “Dexter”) serves as executive producer with David S. Goyer (“Man of Steel,” “The Dark Knight Rises”). “Constantine” is produced from Bonanza Productions in association with Warner Bros. Television. The show is based upon characters published by DC Entertainment.

NBC's Constantine’ TV series will premiere October 24, but in the meantime check out the latest trailer below, and tell us what you want to see when the DC detective hellblazes onto our screens this fall!
