The "Man of Steel 2" production has an official title: "Batman v Superman: Dawn of Justice."

The Warner Bros. film stars Ben Affleck as Batman, Henry Cavill as Superman, Gal Gadot as Diana Prince/Wonder Woman, Jesse Eisenberg as Lex Luthor and Jeremy Irons as Alfred. 

"Batman v Superman: Dawn of Justice" is currently filming on location in Detroit, Mich., but will also shot scenes in Illinois, Africa, and the South Pacific, according to a news release. 

Director Zack Snyder recently shared the first image of Affleck in his new Batsuit posing next to the Batmobile.  However, fans have yet to see Gadot in her Wonder Woman armor.  Snyder teased details about his first encounter with the new superhero costumes to Forbes.

"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."

"Batman v Superman: Dawn of Justice" will be released to theaters on May 6, 2016.
