"The comic book will influence the history of Batman vs. Superman, on which the writer David S. Goyer and myself will work."
Snyder elaborated on the set-up that The Dark Knight Returns provides for their cinematic world, explaining that Ben Affleck's version of Bruce Wayne will serve as a good opposition to Henry Cavill's Superman.
"Ben brings an interesting counterweight to the performance of Henry in the role of Superman. He has the experience necessary to paint the picture of an older and more advised man than Clark Kent, who bears the scars of a seasoned vigilante while retaining the charm that Bruce Wayne deploys when present in the world."
Written by Chris Terrio, from a screenplay by David S. Goyer, the film will star Henry Cavill and Ben Affleck, in addition to Gal Gadot as Wonder Woman/Diana Prince, Jesse Eisenberg as Lex Luthor and Jeremy Irons as Alfred. Set to open worldwide on May 6, 2016, the film also reunites Man of Steel stars Amy Adams, Laurence Fishburne and Diane Lane.
