Watch Amber Heard practice intense Aquaman fight scene

If her latest Instagram post is any indication, Amber Heard is poised to make waves in the new Aquaman movie.

The All the Boys Love Mandy Lane actress shared a short clip of herself training for one of the upcoming superhero flick’s fight sequences, hashtagging the film’s title while noting the intense training was just “another day at the office” for her.

Before portraying Mera — a queen of the sea and spouse to the titular character played by Jason Momoa — in Aquaman, she will first appear in Warner Bros.’ impending comic book adaptation Justice League, which hits theaters Nov. 17. She can be seen for a brief moment in the new Justice League trailer, which dropped March 25.

Watch Heard prep for her role in Aquaman above. The film, also starring Nicole Kidman, Willem Dafoe, and Patrick Wilson, is scheduled for release on Dec. 21, 2018.
