Actress Holly Hunter and '300: Rise of an Empire' star Callan Mulvey are joining the cast of director Zack Snyder's 'Batman vs Superman' movie.
Tao Okamoto, who played Mariko Yashida in 'The Wolverine', has also boarded the project, with all three stars signing up for unspecified characters never-before-seen in the DC Universe, reported Deadline.
Hunter is an Academy Award and BAFTA-winning actress, who also recently earned a Screen Actors Guild Award nomination for playing an eccentric guru in 'Top of the Lake'.
Filmmaker Snyder hailed Hunter as one of his "favourite actresses" in a statement confirming her casting.
"She has immense talent and is always captivating on screen. I had an opportunity to meet her a while back and knew instantly that I had to work with her, so as we began writing the script I made sure to create a role specifically for her," the director said.
The 'Batman vs Superman' movie is a sequel to Snyder's 2013 blockbuster hit 'Man of Steel'.
The highly-anticipated movie will be released in cinemas on May 6, 2016.
