Man of Steel, meet Elastigirl.

Holly Hunter is the latest addition to the Henry Cavill/Ben Affleck superhero mash-up, tentatively known as Superman/Batman, with Callan Mulvey of 300: Rise of an Empire and Tao Okamoto of The Wolverine also joining the Zack Snyder film. All will will be playing new characters, never before seen in the DC Comics universe.

“Holly has always been one of my favorite actresses,” Synder said in a statement. “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.”

He did not offer specifics on the character The Piano Oscar-winner would be playing. Among the others already cast are Jesse Eisenberg as Lex Luthor, Gal Gadot as Wonder Woman, and Jeremy Irons as Bruce Wayne’s butler, Alfred.

Okamoto, a Japanese actress and Ralph Lauren model, played the crime lord’s daughter, Mariko_Yashida, in The Wolverine, and also appeared in the Japanese TV mystery miniseries Chi No Wadachi (a.k.a. Blood on the Tracks.)

Meanwhile, Mulvey has lately dabbled in the Marvel side of the comic book world, playing S.H.I.E.L.D. agent Jack Rollins in this week’s Captain America: The Winter Soldier. He also co-starred in Zero Dark Thirty, and came to know Snyder through the 300 sequel the filmmaker recently produced.

“I just had the good fortune to work with Callan on 300: Rise of an Empire and was very impressed with his incredible talent,” Snyder’s statement said. “He’s a fantastic actor and I’m looking forward to having the chance to work with him again. And, quite simply, Tao is a striking presence whose beauty is aptly rivaled by her amazing abilities as an actress. I’m really excited to have her joining us on this adventure.”

The untitled Batman and Superman (and Wonder Woman) film is set to open May 6, 2016.
