DC's famous demon hunter is headed to television this fall in Constantine, and NBC has just released its first trailer. The show, based off of the comic series Hellblazer, follows John Constantine's crusade against a hidden evil rising up on Earth. From the trailer, the series looks to be creepy, terrifying, and even a little funny, with pretty impressive special effects for a television show. Matt Ryan of Criminal Minds stars as Constantine, and Lucy Griffiths of True Blood costars as his new demon-hunting partner; a couple of Lost alumni turn up in the trailer too. It'll be airing on Fridays — so you may be recording it for later — but from the looks of it, Constantine has the potential to be a big series nonetheless.
