We’ve known since the packing previews for Batman and Harley Quinn were released that the next DC Comics animated film would be an adaptation of Gotham by Gaslight. The Brian Augustyn and Mike Mignola comic was originally released back in 1989 (a good year for Bat-fans) and spawn a 1991 sequel Master of the Future.
Having ventured in to the domain on magic with Justice League Dark this is the DCAU’s first foray in to the plethora of Elseworlds stories using DC Comics characters. The near 8 minute preview is available in the player below!
Gotham by Gaslight is written by James Krieg and executive produced by Bruce Timm. The voice cast includes Jennifer Carpenter as Catwoman, no other casting announcements have been made as yet. The film is due in late 2017/early 2018.
