New set photos from the “Batman v. Superman: Dawn of Justice” production may have revealed a new character.

Fans have been posting images on Twitter, catching Clark Kent and Lois Lane in action. However, one photo posted on the “Filming in Chicago” account featured a sign that read “Kahina’s double.”

Kahina is a DC character and member of The Others who has a direct relationship with Aquaman. While “Kahina” could be a code name for another character, many are speculating Jena Malone is playing the role.

Malone was reportedly spotted on the “Batman v. Superman” set, which sparked rumors she was playing the female version of Robin, Carrie Kelly. However, the Warner Bros. production hasn’t confirmed or denied her connection to the film.

Other set photos and videos reveal Superman flying through the air. Henry Cavill was spotted on the streets of Detroit strapped into a harness. Watch the videos below to check out the action. See set photos of Cavill and Amy Adams here.

The “Batman v. Superman” production isn’t revealing many details about the film, but cast member Holly Hunter dished to The Wall Street Journal what it was like seeing two iconic superheroes on the same set.

“I have scenes with Superman. He looks phenomenal. And to see Ben [Affleck, who plays Batman] and Henry [Cavill, who plays Superman] together is quite formidable. They are massive hunks of masculinity,” she said.

“Batman v. Superman: Dawn of Justice” is set to hit theaters on March 25, 2016.
