NBC's "Constantine" has a scheduled debut date: 10 p.m. on Friday, Oct. 24, as announced Monday by the network. This puts the show on the latter-end of NBC's fall premieres -- only "State of Affairs" will bow later, on Nov. 17.

"Constantine" stars Matt Ryan as John Constantine, DC Comics' long-running mystical antihero first introduced by Alan Moore, Steve Bissette and John Totleben in 1985's "Swamp Thing" #37. The character starred in the "Hellblazer" comic book for 300 issues, and is currently features in New 52 series "Constantine." Here's NBC's official description:

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.
