Heard has previously posted pictures of herself working with 87Eleven, the production company responsible for the fight choreography in John Wick, John Wick: Chapter 2, and the upcoming Charlize Theron starring Atomic Blonde.
Amber Heard has had to do a lot more than just workout for Aquaman or her cameo in Justice League, but her role as warrior princess Mera seems to demand no less.
All of this is to say that Mera is going to be a serious badass in these movies.
The actress has also had to do a ton of training in other skills to be prepared to handle the onscreen action.
