Warner Bros.’ next animated movie will be Batman: Gotham by Gaslight.

Originally published in 1989, Gotham by Gaslight tells the “What if” story of a 19th century Caped Crusader who comes face to face with the Butcher of Whitechapel. It’s Batman vs. Jack the Ripper written by Brian Augustyn and illustrated by the creator of Hellboy, Mike Mignola.

The back box art for Batman and Harley Quinn lists “A Sneak Peek at DC Universe’s Next Animated Movie: Batman: Gotham by Gaslight” as one of the special features.
