Zack Snyder in a recent interview stated the influence the Frank Miller’s graphic novel The Dark Knights Returns will play on Man of Steel 2. Snyder said the following,”“The comic book will influence the history of Batman vs. Superman, on which the writer David S. Goyer and myself will work.” Zack Snyder went on to explain how Ben Affleck will be a great opposition to Henry Cavil’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.”
Basically what he is saying is that Man of Steel 2 will stick to the storyline of an older and more seasoned batman, and that the difference and deciding factor in the Superman V Batman fight will be Batman’s age and wisdom, weather it is being the best detective and finding out Kryptonite is Superman weakness or something else to do with wisdom and being seasoned remains to be seen. My bet is that Batman/Bruce Wayne finds out about Kryptonite somehow, but regardless, the only thing the movie seems to be sticking to from The Dark Knight Returns is the fact that Batman is older and more seasoned vs. a younger and not battled tested Superman.
