The Dark Knight Returns (film)

A film in the DC Universe Original Animated Movies line, based on the comic of the same name. Batman has been retired for ten years, alcoholic and consumed with grief after the death of Jason Todd. Commissioner Gordon is weeks away from retirement, The Joker has been silently locked away in Arkham for years, and Two-Face is about to be released back into the world with a brand new skin. In Batman's absence, and in the midst of a killer heat wave, Gotham City is overrun with crime, plagued by a monstrously violent gang known as The Mutants. After encountering a Mutant gang in the alley where his parents were murdered, Bruce Wayne resurrects Batman, aided in his renewed crusade by Carrie Kelly, a 13-year-old girl who becomes the new Robin. Defeating the Mutants, though, turns out to be child's play compared to what Batman faces next...

Set to be released in two parts, voice actors include Peter Weller (Robo Cop) as Batman, Ariel Winter (Modern Family) as Carrie Kelley, Wade Williams (Prison Break) as Harvey Dent/Two-Face, and Michael McKean (Laverne and Shirley) as Dr. Bartholomew Wolper.
