It's been a good long while since we've heard very much from the front of NBC's DC-adapted 'Constantine,' but with the fall of superhero TV underway, and our Hellblazing premiere set for October 24, NBC continues lifting back the veil on its new occult detective. Get an in-depth look at 'Constantine''s pilot with a brand-new behind-the-scenes featurette and dozens of new photos!

Audiences already got a tasted of the re-vamped 'Constantine' pilot "Non Est Asylum" at Comic-Con 2014, the few tweaks of which offered additional explanation for Lucy Griffiths' unexpected departure, though the new featurette and photos provide our most in-depth look yet. The photos also offer up a good taste of the effects and scale of the DC-adapted demon detective drama, with executive producer David S. Goyer even putting in a background cameo.

Apart from the additions of 'Guardians of the Galaxy' star Emmett Scanlan as Jim Corrigan / The Spectre, 'The Wire' star Michael James Shaw as DC villain Papa Midnite, along with 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.
