While no other details about the film were announced, Register provided a video of William Shatner announcing the title of the film and that he would be portraying Harvey Dent/Two-Face.
Two-Face is one of the few Batman villains of the day to never appear on the original Adam West and Burt Ward-starring series. Harlan Ellison wrote an episode (correction: story-treatment, thanks Thad!) featuring him that never made it to air, and legend has it that Clint Eastwood was being considered for the role. That Ellison-penned tale was finally adapted into a comic in recent years.
Batman: Return of the Caped Crusaders will be in select theaters for one night only on October 10th, and will hit digital formats the next day. A physical blu-ray release will be coming November 1st.
