A new trailer for Batman: Gotham By Gaslight just dropped, and it's a pretty sweet-looking little animated picture.
Take a gander:
An adaptation of the popular '89 tale that introduced a Victorian Era Dark Knight, who was in hot pursuit of Jack the Ripper, the original comic was penned by Brian Augustyn and drawn by Mike Mignola (Hellboy). Batman: Gotham By Gaslight is widely considered the very first Elseworlds book (which magically placed DC characters in enviroments outside the DC canon). At 48 pages, the original story is definitely sparse, leaving plenty of room for the film's creators to expand on this candlelight universe.
No release date has been set for Gotham By Gaslight as of yet, but it's the first in a string of DC titles releasing in 2018, including Suicide Squad: Hell to Pay and Death of Superman. We'll keep you up to date as more info becomes available.
