Jena Malone who you may know as Johanna Mason from the Hunger Games movies may be in the new Batman V Superman flick. She has visited the set, and the new hair color would be perfect for Carrie Kelley the female Robin character from the comic books. Red hair could also be Harley Quinn or Barbara Gordon (Batgirl), or you know she may just like red hair, and it is a good look on her. Her set visits could also just be that she is good friends with director Zack Snyder, and she just wants to check out one the biggest movies of 2016. Heck I know I would.
Regardless you can read all the speculation over at Batman-news.com.
I would be happy with any of those situations. It would be fun to see a live action Harley Quinn grace the screen.
It would. Quinn is by far the best cartoon universe creation.
Though one of the producers seemed to leak on Twitter that Batman is on the outs with Robin in this movie, so then this casting rumor would make sense. Robin could have a quick cameo and then be setup for future movies.
I hope it is Batgirl since Barbara Gordon is way more important to the DC universe. We will see though.
