Now that filming on Batman V Superman: Dawn of Justice has been ongoing for a few weeks, you'd expect Warner Bros. to at least have confirmed which actors will be playing the major players in the movies. Casting speculation is still ongoing, however, with the most recent rumor pointing to Tao Okamoto (The Wolverine) playing Lex Luthor's assistant, Mercy Graves.

The big news this week, however, was a report that Jason Momoa - the Game of Thrones star who at one point was expected to play Drax the Destroyer in Guardians of the Galaxy - had been cast as Aquaman, and would make his first appearance in Batman V Superman after being drawn to the surface by the impact of Zod's world engine on the Indian Ocean.

The report was quickly corroborated by other sites like THR and Variety, but Momoa has been very cagey about the issue since he was originally said to be in talks back in December 2013, and the HitFix article that broke the latest casting news warned that the actor was "sworn to secrecy" about the role. Sure enough, when Momoa was directly quizzed about playing Aquaman during his appearance on Jimmy Kimmel Live, he refused to confirm or deny the reports. Here's a transcript of the conversation for parsing.

Jimmy Kimmel: Will you wear the green leotard in the water as Aquaman?

Jason Momoa: [Stroking beard] Am I answering or asking the question... would you like to see me in green leotards? [Laughs]

JK: I don't know. I like that they cast you as Aquaman, because Aquaman...

JM: Those are all rumors, I'm just...

JK: Really? Because I have a printout that says "Jason to Play Aquaman in Batman V Superman." Now, is that a rumor or is that happening?

JM: [To audience] That would be pretty exciting, what do you think? [Applause] We'll just have to wait, we'll have to wait and see.

Jason Momoa responds Aquaman rumors

The most likely explanation for Momoa acting so coy is that Warner Bros. asked the actor to sign a non-disclosure agreement. It's possible that the studio was planning for the Aquaman casting to be a surprise reveal at San Diego Comic Con next month. It could also be the case that Momoa is only in final talks, as opposed to already being officially signed up for the role.

Momoa has been busy of late, having made his feature directorial debut this year with Road to Paloma, a drama about a Native American who goes on the run after avenging his mother's death. Speaking retrospectively about why he decided not to star in Guardians of the Galaxy in an interview with Zap2It earlier this year, Momoa explained that he wanted to stretch himself as an actor after spending four years on Stargate Atlantis playing Ronon, an alien who doesn't do much talking, and then going on to play similar roles in Conan the Barbarian and Game of Thrones.

Momoa has confessed, however, to being a big comic book fan, and playing Aquaman would certainly be the perfect opportunity for him to step into the comic book movie world without getting pigeon-holed into another "thug" role.
