10:32 AM PDT 5/21/2014 by Tatiana Siegel, Borys Kit

Production got under way on the film, which stars Henry Cavill in the role of Clark Kent/Superman and Ben Affleck as Bruce Wayne/Batman.

The untitled Batman-Superman movie finally has a title.

Warner Bros. unveiled the title as Batman v Superman: Dawn of Justice, just as production got under way in Michigan.

Zack Snyder directs the film, which stars Henry Cavill in the role of Clark Kent/Superman and Ben Affleck as Bruce Wayne/Batman.

The line of "Dawn of Justice" is meant to refer to how the movie sets up the Justice League movie, which Snyder and the studio are already developing. That movie could bow as soon as 2017.

Batman v Superman: Dawn of Justice also stars Gal Gadot as Diana Prince/Wonder Woman, with Amy Adams, Laurence Fishburne and Diane Lane returning from Man of Steel, Jesse
Eisenberg as Lex Luthor, Jeremy Irons as Alfred, and Holly Hunter in a role newly created for the film.

The movie is shooting at the Michigan Motion Picture Studios and on location in and around Detroit. It also will shoot in Illinois, Africa and the South Pacific.

Batman v Superman: Dawn of Justice is written by Chris Terrio, from a screenplay by David S. Goyer. Charles Roven and Deborah Snyder are producing, with Benjamin Melniker, Michael E. Uslan, Wesley Coller, David S. Goyer and Geoff Johns serving as executive producers.

Principal photography will take place on location at Michigan Motion Picture Studios and on location in and around Detroit, Michigan; Illinois; Africa; and the South Pacific.

Set to open worldwide on May 6, 2016, Batman v Superman: Dawn of Justice is based on Superman characters created by Jerry Siegel & Joe Shuster, Batman characters created by Bob Kane, and Wonder Woman created by William Moulton Marston, appearing in comic books published by DC Entertainment.
