NBC's 'Constantine' TV series brought to Comic-Con 2014 an updated version of its pilot to help explain its early season cast change, but also the good news that veteran genre composer Bear McCreary would score the series based on DC's 'Hellblazer' comic. Now, a new featurette for the 'Constantine' TV series reveals McCreary's moody composure, blending hard rock with harpischord for DC's demon detective.

Though NBC's new featurette curiously omits any actual interview with McCreary ('The Walking Dead,' 'Battlestar Galactica,' 'Agents of S.H.I.E.L.D.') on his composure, we do get a rich taste of the score, and footage of the pilot interspersed with the orchestra recording. It's certainly a more memorable score than we've heard in recent years, and we imagine the graphics that accompany the music to prove every bit as compelling.

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 Bear McCreary's score in the featurette above, as well as the latest trailer below, and tell us what you want to see when the DC detective hellblazes onto our screens this fall!
