However, Ellison’s story, titled “The Two-Way Crimes of Two-Face,” was adapted in 2014 as a one-shot comic book called Batman ’66: The Lost Episode #1.
Although the original Batman TV series featured many prominent members of the Caped Crusader’s rogues gallery, Two-Face never made the cut.
As you can see, not only is William Shatner voicing Two-Face, but his normal-looking side looks just like he did in his younger years.
Harlan Ellison did pen a story featuring the duality-obsessed evildoer, but the episode never aired, supposedly because the character was considered to be too gruesome for children to see.
