Amber Heard prepares for ‘Aquaman’ with a stack of comic books

We’ve seen Amber Heard physically preparing for her role as Mera in Aquaman, and now the actress is preparing mentally as well.

Heard just shared a photo on Instagram of a stack of Aquaman comic books. “Catching up on my reading #aquaman #dccomics,” she wrote.

Heard is expected to head down to Australia in the next few weeks to begin work on Aquaman. The movie is being directed by James Wan and will be released on December 21, 2018.
