Warner Bros has added Holly Hunter, 300: Rise Of An Empire star Callan Mulvey, and The Wolverine‘s Tao Okamoto to join Henry Cavill (Superman), Ben Affleck (Batman), Gal Gadot (Wonder Woman), Jesse Eisenberg (Lex Luthor), Jeremy Irons (Alfred), and Man Of Steel returnees Amy Adams, Laurence Fishburne and Diane Lane in the Zack Snyder-directed film.

The trio will play new characters. Mulvey just worked with Snyder in the 300 sequel. Chris Terrio and David Goyer wrote the script, and Charles Roven and Deborah Snyder are producing. The pic opens May 6, 2016.
