Updated May 19, 2017: Mera actress Amber Heard herself has tweeted another look at her costume in Aquaman from her first day of filming, seen here. Though differently lit, this image shows off the range of color in her scaled body suit.
Original Story: Aquaman director James Wan has tweeted the first image of Amber Heard as Mera in the film.
In the image, Mera sports a much more faithful comic book look than that seen in previous images of her appearance in Justice League. No images of Aquaman's look for the film have been released, though his upgraded Justice League armor has been seen in various promotional materials.
Aquaman is due out in theaters December 21, 2018.
