Jena Malone is a part of the Batman v. Superman: Dawn of Justice cast, multiple sources confirm to The Hollywood Reporter.

However, whether or not she is playing a female version of Batman’s erstwhile sidekick Robin is being kept close to the Bat-chest.

New to the voice stable is Jeremy Sisto (Suburgatory), who will voice Talon, the Court’s almost unstoppable assassin.

Malone’s name surfaced in a report on Central Michigan NBC affiliate WILX-10 (the Warner Bros. tentpole is shooting in Detroit).

While describing a scene that would be filming — a fight between Batman and Lex Luthor at a swank party — a reporter for the station dropped the news that the script featured a female Robin character — and that Malone could be playing her.

The report then cut to a person claiming to be an extra — and the source of the information — who said that a multimillion-dollar lawsuit could be filed against anyone violating the movie’s nondisclosure agreements. In a bid to protect the source, only the person’s hands were shown and his/her voice was altered, giving the affair a Dr. Evil-meets-a-Munchkin vibe.

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. That story introduced Carrie Kelley, a schoolgirl who is saved by the Caped Crusader.  

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

Warners, as usual, had no comment.
