Check out the trailer for Batman: Bad Blood here, and Frank Miller speaks on a few things too:
Batman: Bad Blood follows Son of Batman and Batman vs. Robin, with the returning cast including: Jason O’Mara (Batman), Stuart Allan (Robin), Sean Maher (Nightwing) and Morena Baccarin (Talia al Ghul).
Ernie Hudson is also voicing Lucius Fox, who is a longtime associate of Bruce Wayne and Batwing’s father.
