We finally know a big mystery role cut from 'Batman v Superman'

"Batman v Superman" will debut a lot of DC characters to the big screen. Not only will we see Ben Affleck as a new, older Batman, we'll also get the first on-screen appearances of Wonder Woman, The Flash, Aquaman, and maybe even more superheroes.

But there's at least one role that's been kept well hidden, until now.

One of the biggest mysteries of "Batman v Superman" has been Jena Malone's role. You may remember her as the fiery, outspoken Johanna Mason from "The Hunger Games." (She was the one who stripped in the elevator in front of Katniss.)

The Hollywood Reporter first confirmed Malone was cast in the film back in October 2014. Rumors pegged her to play a version of Robin, or possibly Batgirl/Barbara Gordon. Well, it looks a survey from Warner Bros. spilled the beans.

Warning: There are spoilers ahead!

Comicbookresources noticed a Reddit posting showing off a screenshot of a survey taken by members of Warner Bros.' A-List Community site. (You can apply to be a member, here.)

Among the questions in the survey, one asked members which actors/characters they would like to see "more, less, or the same amount of" in future advertising for the film.

Malone is mentioned and her role appears to be Barbara Gordon.

Gordon eventually becomes one of Batman's sidekicks in the comic, Batgirl. Depending on the timeline, Gordon goes on to become another heroine known for her hacking skills, Oracle as well.

Unfortunately, we won't get to see Malone make an appearance in "Batman v Superman." Her role was cut from the theatrical version of the film.

Malone will appear in the R-rated cut of the film which will be available on the Blu-ray release for the movie.
