Attendees at the Batman: The Dark Knight Returns, Part 2 panel at the IGN Theater in the Jacob Javits Convention Center at the New York Comic-Con on Saturday got a sneak peek at the epic animated conclusion to Frank Miller’s story featuring Gotham City’s Caped Crusader.

Moderator Gary Miereanu introduced long-time DC Animated producers: multiple Emmy Award winner, voice and dialogue director Andrea Romano, along with as called by Miereanu, “the architect of superhero animation” Bruce Timm. To the crowd’s delight, intros were immediately followed by a trailer of the upcoming sequel to Batman: The Dark Knight Returns, Part 1.

Another clip was shown which featured the Joker on a talk show, in which the host was voiced by Conan O’Brien. At first the footage was campy, then turned rather sinister as the Joker manifested his controlled viciousness.
