Actor Michael Emerson (Lost, The Practice, Person of Interest) will be voicing the Joker in the second Batman The Dark Knight Returns DC Universe animated original video. Fans know that this animation is based on the 1986 Batman: The Dark Knight Returns limited series by Frank Miller, Klaus Janson, and Lynn Varley and tells the tale of Batman in a future dystopian Gotham city.
Emerson says ""He's one of those great villains that an actor like me likes to play because he has layers — he has a face for the world and a face for himself" and finds the character "delightful and confounding".
Dark Knight Returns will also feature the voicework of Peter Weller (Batman), Mark Valley (Superman), Ariel Winter (Robin), David Selby (Jim Gordon), and Wade Williams (Harvey Dent).
Part 1 of the two-part animated movie will debut on September 25, 2012 on DVD, Blu-ray and digital download. Look for part 2 in 2013.
