The film will be released on Blu-ray, DVD, and digital platforms on September 25th. It's described as follows:
It’s been a decade since Bruce Wayne hung up his cape, following most of the other superheroes who had been forced into retirement. Facing the downside of middle age, a restless Bruce Wayne pacifies his frustration with race cars and liquor – but the bat still beckons as he watches his city fall prey to gangs of barbaric criminals known as The Mutants.
Peter Weller provided the voice of Batman/Bruce Wayne and is joined by David Selby as Commissioner Gordon, Ariel Winter as Robin, Wade Williams as Two-Face and Michael McKean as Dr. Bartholomew Wolper. The film is directed by Jay Oliva, written by Bob Goodman and executive produced by Sam Register and Bruce Timm.
