According to a Gotham showrunner, Harley Quinn may have already appeared on the show and is a character that fans have been watching for a long time. At least that's the tease executive producer Ken Woodruff told IGN at yesterday's TCA Summer Press Tour. "You may have already seen Harley as a person that you thought you had met and known for a long time. So we always reserve the right to sort of do that as well."
Selina Kyle actress Carmen Bicondova apparently didn't know anything about that development, reacting with genuine surprise, "Ummm, I didn’t know that!"
It seems Woodruff may have revealed too much as his fellow executive producer, John Stephens quickly added, "the Harley Quinn of it all is a bit more of a sticky wicket but it’s one we’ve already thought about for the character. We don’t want to give too much away but it will definitely be someone connected to the Joker cult world that we have set up. But it’s down the road, later in Season Three right now."
It's obvious the show is looking to ride Suicide Squad's moment in the pop culture spotlight as the show will also be introducing a proto-version of Killer Croc "fairly early in season 3."
The question now is what previously featured character on the show could actually turn out to be the show's version of Harley Quinn?
Season 3 of Fox's Gotham premieres on September 19.
