Andrew Kreisberg producer on Arrow told Comic Book Resources not to expect more of Harely Quinn this season. While she had the tiniest of cameo’s in season two’s Suicide Squad episode, DC didn’t even really want that happening. Andrew Kreisberg said,
“There are very few things we’ve asked DC Comics for that we haven’t gotten. That was something you asked for, and what you saw is a compromise that Geoff Johns and I came up with. To even get that much was a thrill for us. I know that they may have other plans for her, but it was certainly an Easter egg that thrilled us. But the Suicide Squad will definitely be back. Whether we see the ‘deranged female killer’ we saw before, we’ll have to wait and see.”
Other plans? I’m skeptical we’ll see a live action Harley Quinn anytime soon. Though the way DC seems to be cramming every character in the company’s history into Batman vs Superman that would be my guess where we’ll see her next. The longer DC teases the character the more they run the risk of disappointment when she does finally reveal herself. One plus for a live action version is that hopefully we’ll see a costume that is practical enough for the actress to move normally. I’d like to see the classic version, though I know that is wishful thinking.
If DC asked my input on Harley I’d tell them to translate the current Amanda Conner and Jimmy Palmiotti into a late night cartoon. It would translate perfectly and could even expand the fan base if it was paired with someone akin to Rick and Morty or Archer. But then again DC hasn’t called me yet.
