John Con Noir is a one-episode clay-stop motion animation web series. The web series premiered on January 16, 2015 alongside the broadcast of Constantine, as well as online. The web series is developed by Cool Town Creations to support the petiton for the television series. It features Matt Ryan reprising his role as John Constantine, and Frankie Wagner as Rosacarnis.
Using claymation, we see the story of John heading out to try and find two missing writers, David S. Goyer and Daniel Cerone... and John knows that they are the showrunners for the story of his life and if he doesn't find them, there will be no more Constantine.
