Jena Malone has been added to the star cast list of upcoming 'Batman v. Superman

According to the Hollywood Reporter, it has been hinted that the 'Hunger Games' actor might be playing Robin in the most anticipated superhero movie.

A female Robin is not out of the realm of possibility for the movie. Director Zack Snyder has said previously that the movie was taking many cues from The Dark Knight Returns, the classic Frank Miller miniseries published in the 1980s.

Batman v. Superman is also rumored to feature Nightwing, who is a former Robin now grown to adulthood.
