Warner Bros. and DC Entertainment have just dropped the first official trailer for the R-Rated Justice League Dark animated feature. Check it out after the jump.

Much like Batman: The Killing Joke, Justice League Dark isn’t really one for the kiddies, with darker themes and a fair bit of the horribleness that we’re not entirely accustomed to seeing. Heck, they even have John Constantine in here.

Justice League Dark is directed by DC Animation veteran Jay Oliva, with Matt Ryan as John Constantine (reprising his live-action performance), Jason Omara as Batman, Camilla Luddington as Zatanna, Nicholas Turturro as Deadman and Ray Chase as Jason Blood/Ertigan. The cast is joined by Jerry O’Connell as Superman, Rosario Dawson as Wonder Woman, Enrico Colatoni as Felix Faust, Alfred Molina as Destiny and Roger R. Cross who plays both Swamp Thing and John Stewart.

Justice League Dark is set to release on Blu-ray and as a digital download sometime in early 2017.
