As part of the ongoing social media campaign to get Warner Bros. Animation to put something together, actress Susan Eisenberg – who played Wonder Woman – shared a Tweet to whip up some support from fans. In response, one individual questioned whether Mark Hamill could be involved as well, given that he played the Joker in several episodes of the show, which was a spinoff of the acclaimed Batman: The Animated Series.
Can @HamillHimself come too?
