She will make her appearance first in Justice League, the movie that introduces various characters and story threads to fully launch the cinematic universe based on the DC Entertainment characters.

Warners had no comment.

Heard will play Mera, the love interest of Aquaman and eventual queen of Atlantis. First appearing in 1963, the character’s powers include the ability to control and even solidify water.

James Wan is attached to direct Aquaman, which is undergoing a dual-track development, meaning there are two separate scripts that are being worked on concurrently.

David Leslie Johnson, who is Wan’s writer on The Conjuring 2, is working on one script, while the other one is being penned by Kurt Johnstad, who wrote 300 with Zack Snyder, who is directing Justice League, producing Aquaman and is one of the architects of the DC movieverse.

Justice League is set to begin shooting in April and is slated for a Nov. 17, 2017, release date. Aquaman is due to hit shore eight months later on July 27, 2018.

Heard, last seen in Magic Mike XXL, currently appears with Eddie Redmayne and Alicia Vikander in awards player The Danish Girl. She also has crime thriller London Fields in the can.

Heard is repped by WME and Karl Austen at Jackoway Tyerman.
