Regarding Batman Vs. Superman, Snyder is asked if they are building a trilogy with these movies, with Snyder offering up that Justice League is next, which includes hint of a "bigger enemy."
"In a weird way, Justice League is the next step for these characters," Snyder offered. "You know to form a bigger team... Maybe there is a bigger enemy to fight."
Snyder also talks about working with Ben Affleck and Henry Cavill in the video.
"Batman v Superman: Dawn of Justice" has a March 25, 2016 release starring Ben Affleck as Batman, Henry Cavill as Superman, Gal Gadot as Wonder Woman, Amy Adams as Lois Lane, Laurence Fishburne as Perry White, Diane Lane as Martha Kent, Jeremy Irons as Alfred, Jesse Eisenberg as Lex Luthor, Ray Fisher as Cyborg with Callan Mulvey, Holly Hunter as Senator Finch and Tao Okamoto as Mercy Graves. Justice League is to follow directed by Zack Snyder as well.
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.
