This hot new trailer for the upcoming thriller Constantine was unveiled on Saturday, July 26, as Warner Bros. Television Presents a Night of DC Entertainment at Comic-Con 2014. Matt Ryan stars as John Constantine, an irreverent, working-class con man and occult expert waging war against the forces of darkness - from both within himself and the outside world. Take a look at the first footage before the series premieres Friday, October 24, at 10/9c on NBC, then read on for information about newly confirmed characters.

Series creator David S. Goyer recently spoke with IGN, where he confirmed that Papa Midnite and the Newcastle Crew from the Hellblazer comics will be popping up in Season 1.

"We have access to the occult corner of the DC Universe. I'm sure many of you saw the Doctor Fate helmet [in the pilot], and that was a clear indicator of our intentions."

The series creator also announced that Bear McCreary (The Walking Dead, Battlestar Galactica) has signed on as the show's composer.

John Constantine is a man waging war against the forces of darkness -from both within himself and the outside world. An irreverent, working-class con man and occult expert, he's an experienced exorcist and demonologist with an extensive list of supernatural contacts, each with their own paranormal talents and abilities. Following the aftermath of a tragic incident, Constantine has voluntarily checked himself into an asylum and sworn off investigating matters of the supernatural, but when a cryptic message calls him out to reluctantly resume his old life, he finds himself saving the life of a young woman whom he's never met but is connected to in a very important way. With dark forces gathering power in the world, Constantine allies himself with Manny, a rogue warrior angel, and his giant childhood protector, Chas-the only friend who's managed to stay alive. Based on characters published by DC Entertainment, Constantine reflects the lore of the fan-favorite comic, combining noirish storytelling with the evolving mythology of John Constantine, a morally challenged character who doesn't come down on the side of either good or evil...but ultimately might be the only thing defending us against the dark forces from beyond. The series stars Matt Ryan (Criminal Minds: Suspect Behavior), Harold Perrineau (Lost), and Charles Halford (True Detective) and is executive produced by Daniel Cerone (Dexter) and David S. Goyer (The Dark Knight trilogy). From Bonanza Productions Inc. in association with Warner Bros. Television, Constantine will air Fridays at 10/9c on NBC, premiering October 24.
