It may have taken longer to get underway, but now that it has, WB's Justice League movie universe is adding more and more characters and cast members by the day. But as reliable as heroes like Superman, Batman, or even Wonder Woman may be, audiences are still not sure what to expect from James Wan's take on Aquaman. With leading man Jason Momoa (Game of Thrones) guaranteeing a hero that nobody will (openly) mock, the surrounding story, setting, and supporting characters are far less clear. Thankfully, one key figure can apparently now be locked in place.

After previous rumors claimed that Amber Heard (Magic Mike XXL) was in talks to take on the role of Mera, Aquaman's main love interest (and eventual Queen of Atlantis), the actress has now personally confirmed that she's accepted the role... and even tried on the costume. Since those same reports stated that Heard would make her debut in Justice League Part 1 before the standalone Aquaman movie, fans may not have to wait as long as they fear for some official updates or details.

The confirmation comes not from the studio, but from Heard herself. While being interviewed by ET for her upcoming film The Adderall Diaries, Heard was asked if she was able to tease anything about the role of Mera, and whether or not she had tried on the costume:

"Yeah, yeah I have. It's... interesting [laughs]. I'm wearing, um... it's like, half suit of armor, half scales. I don't know, it's strange. But we're in the process of building it now, so it's coming along."

Fans may have already gotten their first look at concept artwork of Mera in costume, when the artwork was teased - alongside Aquaman's full armor costume - in behind the scenes photos taken of Zack Snyder and Momoa. It was impossible to pick out details, but Heard's description seems fitting with the entire universe underneath the seas of DC Comics' version of Earth. In fact, a blend of armor and scales is likely to be expected from her love interest, as well.

For the unfamiliar, Mera is more than your everyday Atlantean, and a powerful (sometimes too powerful for her own good) superheroine herself. Blessed with the same strength and endurance as Aquaman, Mera's expertise lies not with sea life, but water itself, bending it to her will... and if required, able to evaporate every bit of it in a human body. It's hard to know just how Mera's presence in either Justice League or Aquaman will impact the story, since it's still completely unknown if the film will follow a version of Aquaman already in place as King of Atlantis, with Mera by his side, or his pursuit of the throne after clinging to his half-human side.

Now that Heard has confirmed the role, first in Justice League, then taking on a larger one in James Wan's Aquaman, what do you think of her casting? Does she seem like an interesting contrast to the hulking hero, or did you have another actress in mind? Let us know in the comments, and we'll keep you updated when and if official details arrive.
