DC's next animated movie may be taking a trip back to the past! According to some leaked art from the back of the DVD box for the Batman and Harley Quinn animated release, Gotham by Gaslight is DC's next animated movie. It's a fact that Batman and Harley Quinn will have a featurette about the next movie, but the press release left it nameless until now.

After the DVD's back cover was released on Reddit, several websites ran with the story. Though it wouldn't be too hard to fake this one, it seems like an odd subject for a hoax. Bleeding Cool reached out to a source at WB Home Entertainment in an attempt to verify, but they had no comment.

Gotham by Gaslight was a 48 page DC one-shot released in 1989 (but set in 1889) by Brian Augustyn, Mike Mignola, and P. Craig Russell that sees Batman face off against Jack the Ripper.

Although not originally labeled as such, Gotham by Gaslight is considered to be the first Elseworlds story, where DC Comics heroes are taken out of their usual setting and put into alternate timelines or realities. Subsequent printings have included the "Elseworlds" logo.

In 1889, Bruce Wayne is on a tour of Europe. His trip to Europe ends in Vienna, where he has come to learn from Dr. Freud. Bruce tells Freud that he has a recurring dream in which he recalls the murder of his parents and decides he must return to Gotham City. On the return trip, Bruce meets Jacob Packer, an old family friend who he calls Uncle Jake, who also returned from a trip to Europe. Shortly after arriving, Inspector Gordon informs Wayne about criminal gangs currently operating in Gotham. Gordon also shows Bruce the case of a man who poisoned his wife and tried to commit suicide with the poison, which left him alive with a permanent grin. Bruce takes up the mantle of Batman to fight criminals on the street. At the same time, a series of murders of women take place and some people begin to suspect that Batman is the murderer. It is soon discovered that Jack the Ripper has come to Gotham, as the murders in Gotham City seem to resemble the Ripper murders.

Batman and Harley Quinn will be released on August 15. Watch the trailer below:
