Depending on how big a fan of spoilers you are, this could come as either excellent or horrible news. “Batman V. Superman: Dawn of Justice,” the first film in Warner Bros.’ Justice League franchise, which will be out in 2016, will include the character of Robin as well.

This time though, Batman’s ever-faithful sidekick will be female.

According to ComicBook.com, one extra from the set in Michigan agreed to breach their NDA and talk about what they’d seen so far of the film, which is now shooting there and in Detroit.

The biggest surprise is finding out that the script includes Robin, who will be female. This has sparked rumors that Jena Malone (“The Hunger Games,” “Sucker Punch”) will be appearing as Carrie Kelley / Robin.

The extra also talks about a scene shot at the Art Museum on the campus of the Michigan State University, which will see Bruce Wayne and Lex Luthor get into a very violent fight – so violent that it will require a military intervention, but also include “fireworks, paparazzi and heavy special effects.”

“Dawn of Justice” will see Henry Cavill reprise his role as Superman from “Man of Steel” and Ben Affleck make his Batman debut. The film is directed by Zack Snyder, who directed “Man of Steel,” but it’s not a sequel to this one, aiming instead to introduce all the superheroes that will appear in the “Justice League” movie.

Warner Bros. has been working for years on a superhero film franchise to rival Marvel’s, but it seemed to get started with the wrong foot with Affleck’s casting. Gal Gadot’s casting as Wonder Woman only made matters worse, just like Jesse Eisenberg’s as Lex Luthor. Who knows how the fans will react to a female Robin.
