Getting a jump on NBC's Constantine, Kevin Housand, Charles Winston Propst and One Riot One Ranger Productions have created Justice League Dark, an 11-minute short that sends the DC Comics occult detective and Zatanna on a mission to rescue her father -- with a little bit of help.

The fan film also serves as a prologue of sorts, teasing the introduction of at least one other character from DC's supernatural stable, which would presumably lead to the establishment of Justice League Dark.

Justice League Dark features John Constantine leading Zatanna through a city with the promise of rescuing her father from Hell. They meet a disguised Deadman along the way. The three are forced to work together and fight a dark force made flesh in order fulfill Constantine’s promise to Zatanna. Look out for a nod to another familiar Justice League Dark character in the final seconds of this film.
