So far neither of the other Atlantians have been seen during filming, but both Dafoe and Amber Heard, who plays Mera, have been spotted in Iceland where Justice League is filming.
IGN has been able to release the first official look of Heard as Mera, with a very comic accurate costume on display for the leading lady.
For fans of the character, this should be a great first look at the live-action version of Mera.
Momoa got his first chance to play the king of Atlantis in Batman V Superman: Dawn of Justice, but is set to have a much larger role in Justice League.
