While speaking with EW, director Zack Snyder recalled the time he was trying to to figure who the villain would be in the Man of Steel sequel, before Batman v Superman: Dawn of Justice was even dreamt up at Warner Bros.
The direction of the Man of Steel sequel changed when Zack Snyder made a suggestion at a meeting with screenwriter screenwriter David S. Goyer and executive producer Christopher Nolan, which was when the idea of Batman v Superman was born.
Henry Cavill who stars as Superman in the film also explained that Batman v Superman is far from a Man of Steel sequel.
In Batman v. Superman: Dawn of Justice, fearing the actions of a god-like Super Hero left unchecked, Gotham City’s own formidable, forceful vigilante takes on Metropolis’s most revered, modern-day savior, while the world wrestles with what sort of hero it really needs. And with Batman and Superman at war with one another, a new threat quickly arises, putting mankind in greater danger than it’s ever known before.
Batman v. Superman: Dawn of Justice hits theaters on March 25, 2016.
