Jason Momoa might be the newest cast member to join the "Batman vs. Superman" production.

Batman News reports sources revealed Momoa has signed on to the film, but didn't confirm which role the "Game of Thrones" actor will possibly be taking on in the film.

"According to my source, Momoa signed the dotted line and joined the Batman vs. Superman cast a couple of months ago," Batman News reports.  "There's no word yet on who Momoa will be playing, but previous rumors have tied him to Aquaman. I'm labeling this as a rumor for now, but I feel that this information is accurate based on who I got it from."

In other "Batman vs. Superman" news, director Zack Snyder recently spoke with Forbes about his reactions to seeing the Batsuit, Superman costume and Wonder Woman armor lined up together in the same room.

"The thing also that's really fascinating for me is that, even just in the tests we've been doing, the costumes, right? You basically have Batman and Superman - and this is without Ben [Affleck] and Henry [Cavill] in the costumes, but just like the stand-ins, just testing to see what the costumes look like," Snyder told Forbes.  "And  you have them standing there and they're standing in the same shot - and then we have Wonder Woman, you know, all three of them in the same shot. Even just for a test, you really have to go, 'Wow, that's crazy!'"

"Not only is it the first time that I'm seeing them, it's the first time they've ever existed together on screen in a movie," he continued.  "And that's kind of a huge deal. Even just Batman and Superman standing next to each other... [I]t's kind of epic. You do sort of sense the weight of the pop culture iconography jumping out of its skin when you're standing there looking at the two of them and Wonder Woman. It's crazy. But it's fun. I mean, I have the first photo, I've got it in my archive because I was like, 'Okay, I better keep this, it's gonna be worth something."
